OUTSTPNDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR JULY, 1923.
The very unusual insect conditions recorded last month continued through July.
Grasshoppers are still attracting major attention throughout the Iississippi Valley and the Rocky Mountain and the Pacific Coast regions, the trouble extending into the Ohio Piver Basin and the Great Lakes region. In addition to the States reported as being seriously infested with grasshoppers during June, Indiana, South Dakota, Montana, Minnesota, and Nevada were reported in July. In addition to the grasshopper troubles, Utah reports a serious outlook for trouble with the Mormor cricket in the Uinta Valley, one band of these hoppers being 3 miles wide and several times as long.
The alfalfa weevil is established in Sierra County, California.
The Hessian fly infestation throughout the Middle Atlantic States and the Ohio Basin continues below normal, exceDt in New York State, while in the Upper Mississippi Valley the situation is reported as serious in Wisconsin, Missouri, Nebraska, Kansas, and Iowa, and the pest is apparently on the increase in Minnesota and North Dakota.
The greater wheat-stem maggot is materially affecting the crop in Mlissouri, North Dakota, Nebraska, and Oregon.
The chinch bug infestation is now becoming serious north of the region
reported last month. Reports of infestations are coming from southern Michigan, southeastern Iowa, and South Dakota. In Missouri calcium cyanid is proving an excellent material for use in chinch bug barriers.
The stalk borer is rather generally reported from New England, the Yiddle
Atlantic States, the Ohio River Valley, westward to South Dakota, and southward to Missouri.
* The garden webworm, both as a truck and as a field crop pest, is reported
from Missouri and Kansas. In Kansas some fanrers report a total loss of the second cutting of alfalfa.
The apple tent caterpillar was generally abundant over New England and
the Middle Atlantic States, with severe infestations also reported from. Wisconsin.
An interesting note has been received from Mtichigan to the effect that
the anthicid beetle Notoxus talpa has been riddling the fruit of sweet cherries
The rose chafer is epidemic throughout New England and the V'iddle
Atlantic States, south to Virginia and through the Ohio River Valley, and northward to Michigan, while the southwestern species, Macrodactylus uniformis, is reported as very abundant in Dona Ana County, New Vexico.
Scutellista cyanea has been discovered in New Orleans feeding on the
black scale. This parasite was sent to Dr. H. A. Morgan, then located at Baton Rouge, in 1896 by Doctor howard. There isino record, however, of its having been taken in the field in Louisiana until the present discovery. It is possible that its occurrence here is due to this introduction.
The sweet potato weevil is now authentically reported from Stephens County, Okla., where larvae were collected early in June.
The Mexican bean beetle is apparently spreading more rapidly than last year in South Carolina, and is now well established over central Tennessee and Kentucky. The last report placed the insect very near the Ohio line.
Wireworms are very seriously infesting onions in the northeastern part of Indiana, where a company reported losses amounting to from $15,nO0 to $20,000.
The July 20 survey of the cotton boll weevil is contained in this number, the pest having been observed over practically the entire Cotton Belt during July.
The cotton worm was observed on July 6 at Baton Rou e, La., where nature larvae were collected. It appeared in Hidalgo County, T4.-, as early as June 10, and by July 14 an outbreak extended from Browansville along the coast as far as Liberty County and inland to the main line of the Southern Pacific Railway.
By July 20 leafwoxor,-s v:c3re collected at Forest City, Ark.
The dandelion root aphid is reported as attacking a number of ornamental plants in Indiana and Tennessee, and the iris borer is generally abundant from
1,.aine to Pennsylvania and New Jersey.
A new pest is recorded in this number. The European weevil Phllobius
oblonus, known as a pest to apple buds in England, has been found rather nuerous on elms in tle city parks in Rochester, N. Y.
The arborvitae leaf-miner and the elm spankrorm are both recorded as prominent at several points of the northeastern part of the United States.
A geometrid moth, Eulvna hastata, is occurring in enormous swarms over Maine and northern New Hampshire.
OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA POR JULY, 192.3.
The rose chafer is present in great numbers and represents as severe an outbreak as has ever occurred in south-restern Ontario. The main centers of infestation are Middlesex, Elgin, Norfolk, Welland, Peel, and York Counties, but it occurs wherever the soil is light and aandy. The fruit of cherries, peaches, apples, pears, plums, and ornamental plants kavebeen freely fed upon by adults.
The apple seed chalcid has been reared from apple seed at Kelowna in the
Okanagan Valley, B. C.
The clover-seed chalcid has been found at Lethbridge, Alberta, in the
blossoms of alfalfa.
The spring cankerworm has been present in outbreak form in Welland, Norfolk, Northumberland, and Durham Counties of Ontario during the season.
The chinch bug has been found in destructive numbers in a small area 50 miles southwest of Rosetown, Saskatchewan. This outbreak is in an isolated locality 135 miles north of the international boundary and north of the South
Saskatchewan River and is of special interest as one of the first records of this species in the Prairie Provinces in destructive abundance. Edges of several fields of early-planted spring wheat adjoining prairie land have been invaded.
Grasshoppers have been particularly numerous in many parts of western
Canada. The most severe outbreaks are occurring in southern Saskatchewan, Alberta, and British Columbia. Melanoplus atlanis and M. bivittatus are the species at fault in each of the localities. A general absence of Camnula pellucida is everywhere noted. A notable outbreak of M. nackardii is associated with the lesser migratory grasshopper in the southern Okanagan Valley of British Columbia. Here these two species have defoliated young apple trees and small bull pines, and intercrops of vetch and alfalfa have been eaten to the ground.
The forest tent-caterpillar has been very conspicuous in New Brunswick. Caterpillars have been sufficiently numerous to hinder railway trains at several points.
Moths of Eu.lyia hastata Linn. were very numerous at a number of points in southern Quebec and northern Ontario during early July.
The stalk borer has been reported and submitted for identification on many occasions during the past month at points in the neighborhood of Ottawa, Ontario.
Notable i jtry has been caused by the iris borer, Macronoctua onusta Grt., at Toronto, Ottawa, and Montreal.
CEREAL AND FORAGE-CROP INSECTS
GRASSHOPPERS (Acr idiidae)
Indiana J. J. Davis (July 16).- Grasshoppers are more abundant this
year than for several years past and., though not in destructive
numbers at present, indicate probable trouble in a year or
Wisconsin E. G. Bailey (June 20): Grasshoppers are very serious in
localized regions, particularly throughout the northeastern
Minnespta A. G. Ruggles (July 29): Grasshoppers,Camnula pellucida,
have been very busy in the northern half of the State and and we have been trying out Kansas, Montana, and Canadian
methods of control. We have had numerous reports of grasshoppers
in other parts of the State, one right here in Hennipen County
being M. bivittatus. Alfalfa and bean fields are being entirely
North R. L. Webster (July 5): County agents in four of the ndrthwestern
Dakota and north-central counties report damage by grasshoppers in this
week's rye and wheat crop report.
South A. L. Ford and H. C. Severin (July 16): Grasshoppers are
Dakota appearing in the Black Hills country in damaging nrmbers. The
predominating species is !elanoplu bivittatus Say, while there
are more Camnula pellucidai Scudd. than there have been for
several years. We do not expect the damage from this pest that
weave had during the past three years.
Kansas Roger C. Smith (June 26): Mclanoplus bivittatus and M.
differentialis Thomas nymphs of about the third instar are far more abundant than during average years. There are also
quite a few %ttigniiakr in the outbreak.
Texas 0. G. Babcock (June 21): A general increase of lubber grasshoppers (Dictyophorus sp.) is recorded from Uvalde, Rock Springs,
Sonora, El Dorado, and San AxIl. At thesent they are in
practically all canyons over this region and are now ovipositing.
C. H. Gable (July 10): The situation in Mason and Llano
Counties and isolated areas in northern Gillespie County is
serious. They are having a real outbreak. The differentialis
grasshopper seemsto be the chief offender. In Mason and Llano
Counties only about 10 per cent of the land is under cultivation.
Pastures showed an estimated infestation of from 5 to 8 hoppers
per square yard.
Montana R. A. Cooley (June 27): A communication has been received
from Liberty County that "every inch of country is covered
with hoppers. This county seems to be the worst grasshopper
spot on the map, and farmers are in a bad way financially."
Utah I. M. Hawley (June 23): Several species of grasshoppers
are doing considerable damage in northeastern Utah and Millard
County in western Utah. The demand for amyl acetate has
been so great that it is now almost impossible to get it, even
at $5.50 and $6 a gallon. Sodium arsenate in the bait is giving good control in most places. A few growers in the
Uinta Basin are using hopperdozers.
Stewart Lockwood (July 20): I have just returned to Billings
from the Uinta Basin in Utah. The grasshopper doing the damage
is 11. bivittatus, though there were some atlanis Riley,
femur-rubrum DeGeer and nackardii Scudd. I founi that for
the most part the cropped land was not heavily infested with
grasshoppers but that there were several rather large sections where M. bivittatus had done all the damage it could. Several large fields of alfalfa were totally destroyed, hothing being left but the coarser stalks. Few parasites were found. From
conversations with farmers it would seem that they have
witnessed a typical increase in the population of this particular
species of grasshopper, i. e., for several years graashoppers
have not ben a great factor with the farmers, but last year
many fields were slightly damaged and some were destroyed.
This year the localities where there were grasshoppers last
year are now overrun and many more fields have been damaged
to a considerable degree. At the time I was there many of
the females were about to deposit their eggs, and it is
probable that some had already done this.
Nevada C. M. Packard (June 25): Hoppers are still small and
exceedingly abundant in colonies covering from 5 to 20 acres
in Elko County. Cold weather has prevented damage to date,
but with warm weather serious injury to all crops seems
Oregon L. P. Rockwood (June 12): Practically all the damage being
done in Lake and Klamath Counties can be attributed to
CanMula Pellucida. These hoppers -sually oviposit on slight
tidges and knolls in the otherwise poorly irrigated area.
Reclamations have materially increased the area in kich
hoppers oviposit. The trouble has been practically continuous
for five or six years and seems to be increasing in severity.
Stockmen have been compelled to drive stock out of their
pastures when they should have been at their best and, in
many cases last year, cattle died of starvation on the way to
distant mountain ranges. The areas of egg laying are
comparatively small and this gregarious habit should be taken
advantage of in controlling this pest.
Cqlifornia C. M, Packard (June II): Grasshoppers are destructively
abundant in many of the mountain valleys in Modoc and Siskiyou
Cftnties. Systematic control measures are already under way in Modoc County, where good results are being obtained with
the usual poisoned bran bait. The Reclamation Service set aside $5,000 for the use of settlers in the region around
Tule Lake for fighting grasshoppers. Modoc County also
furnished the services of five men to assist in mixing and applying poisons. An interesting machine was devised under
the direction of the Reclamation Sergice, consisting of hose
and burners to which distillate oil under pressure was conveyed,
the whole apparatus being mounted on a truck. About ten acres should be covered at a cost of about $1 per acre. Practically
all of the fttaturd hoppers were killed by this treatment. The
truck was driven forward slowly, with two men on foot, one man handling each burner, and each man covering a swath 30
California Weekly News Letter ,Vol. 5, No. 14 (July 14): A heavy
infestation of grasshoppers is reported from Yolo County. In
the control work in this outbreak 5 barrels of molasses, 700
pounds of Paris green, and 250 dozen lemons were used. Hoppers
are now fairly well under control, but the cold weather has
held back emergence, so that there will probably be heavy
control work for the next two or three weeks.
MORMON CRICKET (Anabrus simlex Hald.)
Utah Stewart Lockwood (July 20): Mormon crickets are not in the
Uinta valley to any degree as yet but I found them in large numbers on the top of Diamond Mountain, which is a high mesa about 2,000 feet above the floor of the valley. During the
trip many bands of crickets were observed.,some of them several
miles long. One in particular was 3 miles wide and several
times as long. All of them were traveling, though each band seemed to be going in a different direction from others. At
the end of the trip I could see 75 per cent of the cropped land was very heavily infested, 20 per cent of the grazing
land was full of crickets, ana the rest had from now and then one to four and five to the square foot. Most of the damage
I saw was done to native grasses.
'Wisconsin E. L. CGambers (June 20): Cutworms are damaging corn in 10
counties throughout northeastern and southwestern Wisconsin,
Nebraska M. H. Swenk (June 15-July 1): During the period covered by
this report the variegated cutworm, Lycohotia margaritosa Haw.,
was numerous, but not enough so to be injurious.
Utah I. M. Hawley (June 15): Corn is being injured by several
species of cutworms, with a loss of about 25 per cent in some
fields near Cedar City.
WHITE GRUNS (Phyllophaga spp.)
Michigan R. H. Pettit (June 1): I received today a few dozen samples of
Lacljnosterna, which is reported from Alamo, in Kalamazoo
County, as having defoliated butternut and walnut trees. It is
also reported Is working on maples to a less extent.
Indiana J. J. Davis (July 16): The species involved in the reported
hickory defoliation at Connersville on June 11 (see Vol. 3,
No. 4, Insect Pest Survey Bulletin, July 1, 1). 155) are principally Lachnosterna hirticula Knoch with occasional specimens of gibbosa Burm. ,fusca Froel. ,and ilicis Knoch.
HESSIAN FLY (hytophaa destructor Say)
New York W. R. Walton (July 30): Professor Crosby reports that partial
count indicates that Hessian fly is worse in western New York
than last year.
Maryland P. R. Myers (July 19): The average spring infestation of our
plats at Cambridge has dropped from 71 per cent last sumner to 6 per cent this summer. This large decrease in infestation is
probably due mainly to two factors; first, the protracted
emergence of the Hessian fly last fall, in which about 12 per
cent of the larvae hatching from late-laid eggs failed to mature;
second, the generally late sowing of wheat last fall throughout
the East on account of the drought.
Virginia P. R. Myers (July 19): The average infestation of the Hessian
fly in the plats located at Warrenton is 4 per cent less this
summer then it was last summer.
Ohio T. H. Parks (July 19): A wheat insect survey in 32 counties
shows no serious damage anywhere. The State average infestation
of straws is 4.4 per cent, compared with 10.9 per cent one year
ago. In 10 northwestern counties only 9 early-sowed fields were
found. These averaged 44 per cent infestat ion, with one field
94 per cent. The average of 81 fields sowed after the safe
dates in 10 northwestern counties was 3-9 per cent of straws
infested. The northern half of the State has 6.4 per cent
infestation while the southern half has only 0.6 of 1 per cent.
No damage is expected this fall.
Wisconsin Emil Swain (July): This pest caused almost a total loss in the
vicinity of Osseo, in Trempealeau County.
Minnesota A. Ruggles (July 23): The Hessian fly is becoming well
established in certain sections w~xre winter wheat is being
Iowa F. D. Butcher (July 24): We examined 30 fields in Page County
and easily found the fly in all of them. The damage varies,
but averages from 3 to 5 bushels per acre for the county. The
total loss is from $100,000 to $125,000 on 35,000 acres.
Missouri L. Baseman (June 27): Reports of serious damage from the
Hessian fly have beei received from Buchanan County and that vicinity. (July): Stubble records from experimental plats
over the State show that the Hessian fly is very abundant and
certain to seriously affect the next crop if thorough and
concerted efforts at control are neglected. The fly is "coming
back" stronger in the southern and northern portions of the
State and is less abundant in the central part.
North C. N, Ainslie (June 26): There is considerable infestation in
Dakota Golden Valley County by the spring brood of larvae. Excess
moisture in June may cause a partial s-umner generation that
will injure grain just above the joints.
Nebraska M. H, Swenk (June 15-July 1): During the last twoeweeks in
June the Hessian fly infestation was somewhat more general than
was realized on June 15 over the portion of southeastern Nebraska
lying west of Cass, Otoe, Nemaha, Richardson, Johnsbn, and
Pawnee Counties. Saunders, Dodge, and Butler Counties seem to
be very generally infested, a condition which extends less intensely west to Merrick County, in the general region of
the lower Platte Valley. Westwaraly along the Kansas border
the infestation extends to Redwillow County, Furnas County being very generally infested. However, owing to-he excellent growing
conditions for the wheat, the loss apparently will be much
less than it threatened to be.
Kansas J W. McColloch (July 10): Out of 606 crop reporters, 320
reported fly damage on June 16. Infestations are located generally
throughout the State. These reports coincide with our surveys,
and we have every reason to believe that the data furnish a good
idea of the distribution. The spring was cool, with excessive rainfall. (July 11): The second spring brood of the hes ;ian
fly was especially large and caused much fallen wheat at harvest
time. The present indications are that the fly will be one of
our major problems throughout the remainder of the year. The
State has been amply supplied with moisture this year, .7hich
again is ideal for the dev ulopment of the fly.
GREATER WHEAT-STEM IVAGGOT (eromyza americana Fitch)
Missouri L. Haseman (July): In some fields this spring as much as 25
per cent of the wheat heads were killed by this pest. The
infestations were local mostly in the western half of the State.
North R. L. Webster (July 3): Infestations in Cass and Richland
Dakota Counties are causing "white heads" in wheat and other small
grains. There is the usual amount of damage.
Nebraska Mo H. Swenk (June 15-July 1): There has been considerable comment
concerning the rather large minuber of whitened heads of wheat destroyed by this pest in some of the eastern counties of the
State. This has been particularly true in Saunders County,
where a large number of fields are reported as more or less infested. One case of infestation in that county estimated
50 per cent of the heads of wheat in the field whitened, but,
as a rule, the damage is small. Lancaster and Colfax Counties
report frequent but scattering infestations with this pest.
The reports were received from June 16 to 29.
Oregon L. P* Rockwood (June 23): Early-sown spring grain on hill
lands in Scoggins Valley show ragged appearance and a small
number of good heads because of injury by these insects
combined with rust and some Hessian fly. Conservatively
estimated, the least damage by these insects is a toll of 20
per cent of possible heads of wheat. The acreage affected is probably not large. From 15 to 20 acres have been seen
so far. Some of the injury has also been caused by ::'romyq
ni-r iventr is.
TvJMAT JOIhTWORM (Harmolita tritici Fitch)
Maryland P. R. Myers (July 19): There has beEn an average increase of
nearly 1 per cent in the infestation of this insect in our
plats at Cambridge.
Ohio T. H. Parks (July): The wheat jointworm has not damagedwheat
in any county. Less than 1 per cent of the strqws were affected
in 30 of the 32 counties visited on the wheat insect survey.
The pest is not increasing.
Indiana J. J. Davis (July 16): This pest is more abundant this year
than for a number of years, particularly in the southern half of
Missouri L. Haseman (June 27): Many samples of injury from jointworms
have been received during the past week. The samples coming in
Eava been from Texas County and that part of the State. I do not think the insect will prove as abundant as in some years.
(July): This pest seems unusually abundant this year. It is most abundant from the Missouri River south over the eastern
half of the State. However, some severe infestations have been
found north of the Missouri River.
W14TS}ATH GALL JOIhTWORM (Harmolita vazinicola Doane)
Ohio T. H, Parks (July 19): This pest is now present in injurious
numbers on wheat sown very late in the eastern half of the
State and also in the southern and southwestern counties. The
pest is on the increase in this area. It has not been found
in the northwestern or central western counties.
FALSE WIRLWSORM (Eleodes spp.)
Colorado Cs P. Gillette (July 19): Pewver complaints concerning false
wireworms ha:e been receive, this year so far than during the two precedIng years. HcTe-er, several cor41aints have
come to this office from Logan County through the county
extension agent. Through him we have arranged some cooperative
work on these worms.
BLACK GRAIN-STEM SAWFLY (Trachelus tabidus Fabr.)
Maryland P. R. Myers (July 19): An examination of material from our plats
at Cambridge shows an increase of nearly 2 per cent in the
infestation by this insect this svzer.
Virginia P. R. Myers (July 19): There has been an increase of nearly 1
per cent in the infestation by this insect in our plats at
Warr ent on.
ENGLISH GRAIN APHID (Macrosiphuam ranariunKirby)
Nebraska M. H. S enk (July 1): Not since 199 have there been so many
complaints of an abundance of the Enig2_ish grain aphid on the wheat heads in southeastern Nebraska as there have been this
CHINCH BUG (Blissus leuconterus Say)
Michigan R. H. Pttit (July 19): We had the first report of the chinch
bug in this State this morning. It came from Union City,
Branch County, where a cornfield is infested.
Ohio T. H. Parks (July 19): Our wheat insect survey revealed some
bugs present in the wheat, but there has beer AQ dmnage to wheat
or corn in any county. The corn is already large and xvill not
suffer under the attack of the few chinch bugs present.
Indiana J. J. Davis (July 16): Chinch bugs are abundant and causing
injury in many sections of the State in the northern two.-thirds.
There are not as many reports to this office as last year.
From reports the heaviest infestation occurs in T7hite and Jasper
Iowa H. 3. Jaques (July 11): The chinch bug is showing up rather
ser ious*y throughout southeastern Iowa and is doing considerable
damage to wheat and corn and some of the other small grains.
I have been working in some fields in Davis County, where rather
heavy damage is being sustained.
Fred Do Butcher (July 14): Chinch bugs have been migrating
from small grain for 10 days. They are more severe over a
larger area than last year. Leef Des 'I'lloines, Van Buren, Henry,
Davis, Wapello, and Lucas Counties report outbreaks.
Missouri L. Baseman (June 27): Complaints regarding the heavy infestation of chinch bugs throughout the State are received daily. I
believe we will find that they are more abundant through the central counties and the northern counties of the Statc when the heaviest migration is on. Weather conditions in the past
week have delayed migration practically two weeks. (July): Late
spring delayed spring migration and breeding for about two
weeks. Rains at wheat harvest (June 15-J'UIY 1) caused wild
grasses to grow in stubble fields, which held up normal migration
to corn. Bugs sifted over Sor about three weeks. In central
Missouri the heaviest movement occurred between July 1 and July 10.
Calcium cyanid as a barrier gave excellent results. For
the best results it is applied in the bottom of a furrow at the rate of I pound of flakes to from 60 to 100 feet of furrow. The
heaviest movement of bugs occurs during the afternoon and the
cyanid is applied when the movement becomes heavy around the
noon hour. One application rill hold the bugs for the rest of
the day if the wind is not too strong. Such a barrier is not
too expensive to maintain,
Since the bugs reached the corn we have dusted it with
powdered calcium cyanid. This has caused some burning on the
upper leaves of small corn and in the tassels, but not much on
the lower blades or in the boots. With a knapsack duster it requires about 15 pounds of dust to do thorough work. When
dust was-iised fuil strength it gave practically complete control.
Very few that fall as dead ever recover, Some die so quickly
they do not withdraw their beaks. The prolonged migration
made it necessary to repeat the applications, and aven after
that a great many bugs are still present in the corn.
South A4 L. Ford and H. C. Severing (July 13): The abundant rain
Dakota this spring has held the bugs in check in most places. The
rains were not general, and in those places where moisture
is needed the bugs are doing much damage, Wheat and barley
seem to be the only grains seriously affected. Corn which is adjacent to wheat and barley is suffering in places. At Geedes murh barley and wheat has been ruined and farmers are burning
it to protect near-by corn. Many farmers are using dust
barriers to protect corn with success. The heavily infested
localities are small in area,, hot being over more than 8 or 10 townships at the outside. This infestation seems to have been
working north at the rate of about 30 miles a year, for the past
Nebr4ska M. H. Swenk (June 15-JUY 1): The situation concerning the
chinch bug has not materially changed since June 15.
Kansas J. W~. McColloch (July 20):- Adults begam to mature about
July 14 and eggs are now being deposited. Chinch bugs are more abundant than in the average year with damage
ranging from a few rows to as high as 30 acres. The
weather has been warm with high rainfall. Fungus and
egg parasites are still active.
SUGAR-EA3M BORER (Diatraea saccharalis Fab.)
Louisiana W. W1. Ingramn (July 20): Sugar-cane moth borers are abundant
in this section and are doing a large amount of damnage to
corn. In many cases they have completely destroyed the ear,
and in some fields the tops of the stalks have broken and
fallen as a result of the borers tunneling.
STALK BORER (Papaire.ma nitela Guen..)
Maine Es 14, Patch (July 21):- Frederick H. Jordan from South
Portland reports "active in garden corn."
N~ew P. Ro Lowry (July): This insect has been reported as injuring
Hampshire corn at Concord, W7ilton, Gossville,, and Winchester. It is
somewhat more abundant than in an average year.
Massachusetts B* IA. Patch (July 17): 0. S. Morse writes from Medford Hillside:
"I find them in tomato plants, rhubarb, golden glow, and
dahlias." The sample sent was a larva of this species about
Ohio T. H. Parked (July 19): This caterpillar is more abundant
than in an average year and is still attracting attention
as a corn pest, where it is being mistaken for the corn
borer. Damage is scattered.
Ind'an J. J. Davis (July 16): The stalk borer has been repeatedly
reported from all sections of the State. Reports began June
26 and are continuing at the present t ime. Crops reported attacked are principally tomato, but also corn, wheat, and
such flower garden plants as zinnia, Shasta daisy, rose,
delphlinium, and cal endu'la.
South Ao L. Ford and H. C. Severin (July 1~4): Damage is not
Dakota serious, but oat fields show considerable damage through
eastern South Dakota, This insect is more abundant than
in the average year,
Mis souri L. Baseman (July): This pest was very abundant and destructive
a little earlier, and many complaints about it were answered.
BILLBUGS (Snhenophorus spp.)
Indiana J. J. Davis (July 16): The billbug, injury at De otte
questionably attributed to Shcenophorus aegualis Gyll. has
been investigated by C. R. Cleveland and the original
tentative determination verified. Corn injury by billbugs
was also reported 6n June 23 from Monticello.
Wisconsin W. H. Eastman (June 23): Considerable damage is being done
at Sparta, and in Buffalo, Monroe, and Sauk Counties.
South A. L. Ford and H. C. Severin (July 5): Several reports with
Dakota specimens have been received. Damage is not serious but
unusual for this State, Infestations occur in Lincoln and
McCook Counties. We had a wet spring but it has been dry for
the last two or three weeks.
CORI-SILK BETLE (LuperoIes varicornis Lec.)
Louisiana T. H. Jones (June 22): W. B. Wheelie wrote from Bogulsa on
June 22: "There is a farmer who lives near the cn:r He has a young field of corn with velvet beans planted in it. The corn is fine- in silk and tassel. The beans have just about
reached the tops of the corn, and there are millions of these
beetles feeding on the bean leaves and eating the fresh corn
silks off; also they are in the tassel. The farmer is very
much worried and they are really doing lots of damage." Adults
accompanied the letter.
Connecticut W. E. Britton (July 6): Three fields are damaged, two only
slightly in patches here and there, and one small field is
50 per cent destroyed at Woodbridge.
A CARABID (Bembidion cua.riiaculatum L.)
Maine G. A. Yeaton through E. 1. Patch (June 29): We found hundreds
of this little black insect. They were apparently feeding on
the roots of the corn, because whenever we found a wilted stalk and dug into the soil they scurried in all directions. We could
not find anything else around the roots.
ALFALFA A!ID CLOVER
ALFALFA WEEVIL (Phytonom us osticus Gyll.)
Utah Geo. I. Reeves (June 25): The alfalfa weevil has neglected its
duties somewhat this season. Therehas not been enough serious
damage in Utah to provide material for control experiments. The
injury became serious just at the last moment before cutting,
having been retarded, as I believe, by the extremely cold
weather. The extensions of the weevil territory are slight and
do not involve any new counties. UBRARY
4 AT PLANT OAR
California G. H. Hecke (quar. Order 34, Amend. 5): "The fact has been
determined that the alfalfa weevil exists in the County of
V1.YJ M (Cirphis unipuncta Ha,.)
Indiana H. F. Dietz (June 22): Army.7orm moths are more numerous than
in the last three years. They were first observed on June 15, and the abundance of adults may indicate an outbreak of
this pest a little later.
J. J. Davis (July 16): Armyworms were sent in from Frankfort
on June 28 vith the report that they were damaging alfalfa.
One Peridroma saucia Hbn. larva was with the several armycorms
submitted, but, apparently, it was not responsible for the
FALL ARiY70RM (Labgma frugiper S & A.)
South Philip Luginbill (June 29): Specimens of full-grown larvae were
Darolina collected today at Columbia, which indicates that migrant moths
must have reached this place about June 15 this year.
GARDN WEB7.M (Loxostege similalis cuen.)
Iowa C. J. Brake (July 27): Garden webworm is reported from several
places in the State as very seriously attacking alfalfa.
Hissouri L. Haseman (July): This pest has just been reported from -estcentral Missouri in destructive numbers in alfalfa. The larvae
are now nearly full-fed (July 20).
Kansas J. R. Horton (July 6): Young corn is 90 per cent destroyed,
early-planted corn only about 10 per cent infested. It is also
damaging cantaloupes slightly; sweet potatoes severely; peas,
beans, cucumbers, radishes, and even Irish potatoes and
tomatoes more or less. Pigweed,and Amdranthus are almost
destroyed in Thage patches and about seven other 7eeds are
damaged. (July 13): The oitbbeaks in alfalfa extend over the entire area of Sedg7ick County. They-were first noticcl about four days after my previous report on this pest. Much of the
alfalfa has been cut in the last four or five days. Large numbers of Loxostege have now pupated in soil cells in this
latitude. Injury is so severe that the fields have a whitish appearance from a distance, where the leaves are chewed full
of holes and webbed together.
Geo. A. Dean (July 7): We have just received a report from Lyon County of the common garden webworm seriously injuring
corn. The bottom or lo7T lands of this county have been flooded,
and I presume this may have something to do with the .,orms
moving from weed-s and low-growing crops into the corn. However,
it is nothing unusual in this State for the webworm to attack
Roger C. Smith (July 10): This pest has been reported from
Manhattan. It is several times as plentiful as during the
previous three years. Moths fly up in clouds. They are
numerous at lights at night. In young growth of plants before
blooming most of the longer stems contain a nest and larva.
Larvae are nearly grown now. It is Ilso reported on corn by correspondents. No natural enemies have been observed.
Archytas analis Fab. are very plentiful and may parasitize them.
J. M. McColloch (July 12): Reports of injury by this pest
have been received from Emporia and Beloit. In bbth cases the
insects attacked pigweed in the field and after killing out
these plants moved to the corn, (July 20): Infestations
occur in eight counties in the northeastern part of the State.
Abundance is much greater than in an average year. Some
farmers report a total loss of the second cutting of alfalfa.
The weather has been warm with high rainfall.
MEAL SNOUT-BOTH (Pyralis farinalis L.)
Kansas Rpter C, Smith (June 26): Moths have been observed around the
haystacks. Only a ew larvae have been seen in old stacks.
Most of the moths appear bright and newly emerged. There will
probably be considerable damage by larvae later. Observations"
were made at Ashland Bnltbtfl near Manhattan. They are far more plentiful than in an average year, probably three times normal.
One to four moths flew up at each beating of the stak with a
net. They were not observed at all last month.
SERPTTINE LEAF-MINER (Agromyza pusilli Meig.)
New Mexico R, Middlebrook (June 25): This pest is attacking a newly planted
field of alfalfa, and attacks one variety more than another.
Infestation occurs in Dona Ana County. This pest was not present
to any extent last year. Its abtuidance has increased 50 per
cent from last month.
Colorado C. P. Gillette (July 18): I regret having to report a rather
severe infestation of the alfalfa nemnatode in Fremont County, near Canon City. The county extension agent states that "in some instances whole stands and fields are being killed out."
This is the first report of this pest in the State so far as I
am awar e.

GREEN APPLE APHID (Anhis rorni DeC.)
New York C. C. Wagoner (July 15): In Ulster County this insect is present
on apple and pear terminals, in some cases requiring control but
not in general.
Indiana B. A. Porter (June 21): A severe outbreak of the green apple
aphid is following on the heels of the rosy apple aphid infestation. In many of the young orchards growth has already been sto-pped. (July 21): This insect is reported as being much
less abundant compared with last month. The severe infestation
of about a month ago, at Vincennes, has about disappeared.
Utah I. hl. Hawley (June 15): This insect is found in small nuzrbers
on trees all over the State, but not in serious numbers.
ROSY APPLE APHID (Anuraphis roseus Baker)
New York G. E. Smith (July 15): This aphid is causing considerable injury
in many orchards in Orleans County.
Indiana B. A. Porter (June 21): Serious damage has been done by this
species throughout southern Indiana, both to foliage and to fruit.
The greater portion of the aphids have now migrated from the apple.
J. J. Davis (July 16): The rosy apple aphid has been more abundant and destructive this year, throughout the State, than for
CODLING VOTH (Carpocapsa Domonella, L.)
Delaware J. F. Adams (July): Serious injury has been noted in several
orchards in Sussex County.
Virginia L. A. Stearns (July 17): Pupation and emergence of the first
brood is about over. The maxinur period of deposition for firstbrood moths occurred from July 7 to.11. The first second-brood larvae left the fruit for cocooning on July 13, and Clocoorning is
on the increase at the present timre.
Indiana B. A. Porter (July 5):. The first second-brood moth emerged in
the insectary today.
J. J. Davis (July 16): The codling moth is very abundant in the
State, all unsprayed trees being heavily infested.
Missouri L. Haseman (July): The second brood of the codling moths appeared
on the wing in central Fissouri from July 5 to 15. In the
southern part of the State they emerged a little earlier and to
the north a little later.
New Mexico R. Middlebrook (July 16): The codling moth is attacking apples
throughout the entire State.
-OLLER (Cacoecia a s a walker)
New York G. E. Smith (July 15): This insect is very plentiful in Orleans
County this year.
Utah I. Eawley (June 13): The fruit-tree leaf-roller is very abundant in Cache and Utah Counties. It is more serious than it has been for several years. We counted 16 new, egg passes on a limb
1 foot long.
TENT CATFRPILL!R ( aj.acosona erica, Fab.)
New England A. F. Burgess (June 30): Var-cus reports i'om Fe England and Lew
and York show that the tent caterpillar ,as cor:,recn and abundant over most
New York of this area.
Connecticut E. M. Ives (June 22): Abundance corrpared "ith an average year is
1 per cent less, and none are to be found in dused orards.
New York G. 1. Codding (May 29): The tent caterpillar is present throughout
southern lew York in larger numbers than have been known for a number
New Jersey A. F. Burgess (June 23): New egg clusters are very crron on wild
cherry in the vicinity of Somerville on this date.
Wisconsin 0. S. Soholt (June 20): At Washburn, infestation is severe in sore
Washington M. J. Forsell (July 7): This pest is very scarce this year in
Snohorish County. The larvae were apare.:tly parasitized, as they
are a i l .g cead on the tents. Us;aliy this pest strips all the
native aides as well as apple crcharcs.
FALL WFB7!RMP (H-phar a cunca Drury)
New York G.E. Smith (July 15): Fct r:.anry are to be found in Orleans County,
and they are of little account et the res. 'nt. tire.
C. C. Wagoner (July 15): The fall 7e0'rorm is rather general over
New Jersey A. F. Burgess (June 23): Small larvae of the first generation are
comnon in the vicinity of Somerville on this date.
Delvaware C. 0. Houghton (June 25): Nests of this species are appearing in
considerable numbers on fruit trees in this vicinity.
Georgia 0. I. Snapp (July 11): This pest is very common on persimmon this
year in middle Georgia.
Indiana J. J. Davis (July 16): The fall webworm has been abundant, especiall
in the southern half of the State. It.is conspicuous both in cities
and in the country, probably more so in cities.
THREE-CORNERFD ALFALFA HOPPER (Stictocephala festina Say)
Utah I.'M. Hawley (June 14): Tree hoppers are serious in young orchards
and twigs of older trees where alfalfa or sweet clover is abundant.
A dormant spray of miscible oil was effective in killing eggs.
SAN JOSE SCALE (A~nidiotus perniciosus Comst.)
New York G. E. Smith (July 15): The San Jose scale is plentiful on fruit in
neglected orchards in Orleans County.
Indiana B. A. Porter (June 2): At Vincennes the first crawling young were
observed. (June 21): First-r-generation crad:,ling your are present
in large numbers. Where careless spraying ,as done, or where the
dormant applications were omitted, the fruit is already badly spotted.
J. J. Davis (July 16): The San Jose scale continues as one of the
biggest problems of the fruit growe -. Horev)r, Ca c,,rt-ol was obtained by the new luoricating-oil cu2sisn, ach drig tne
dormant season, and satisfactory results are also being obtained
with the summer applications of this emuilion.
Missouri L. Haseman (July): This pest has met a new check, lubricatingoil emulsion. iany Missouri gro;e- used it in place of the liresulptur during the last dormaxn- scsce. Genrally good results are
reported, but, like lime-sulphu-, t~e s ray kills only those actually hit by it. This pest also is a Lid its normal schedule, which will
probably result in one less brood this year.
New Mexico R. Middlebrook (July): The San Jose scale is reported attacking
fruit throughout this State, but pretty well controlled by spraying.
Washington E. J. Newcomer (June 23): Late applications of line-sulphur do not
appear to have been very effective this year. A period of war'
weather from April 15 to 17 apparently started the scales growing,
and they were largely able to ov1r-ec eRe effects of the spray
applied aoout this time or later. I one case 18 per cent of the
scale remained alive, and in arcThr per cent were alive, although
the latter orchard was very thoroughly sprayed. Lubricating-oil
emulsion killed 99 per cent at this sase time.
YSTE EL SCALE .(L)dosahes umi .
New York R. E. horsey (June 27): This insect was found on lilacs at Highland
Park, but not numerous. Young were micvg J.une 18 for the first
time this year. Less than usual are to be found.
G. E. Smith (July 15): This scale is abundant in Orleans County in
Indiana J. J. Davis (July 16): The oyster-shell scale continues as a big
problem in the State. It is particularly destructive to lilac,
corpus, and ash. Recently we observed it doing noticeable damage
to walnut shade trees at Portland, and incrusted rose twigs were
received recently from Veedersburg. Tests with summer sprays applied 10 days to two weeks after hatching gave good control.
Caustic soda fish-oil soap 1 pound, nicotine sulphate 1 ounce,
and water 5 gallons gave variable results, but immost cases
practically 100 per cent kill. Two per cent lubricating-oil
emulsion and Sun miscible oil (a new type of miscible oil) 1 to 40 gave practically 100 per cent control. In no case did the
treatments injure foliage.
Colorado C. P. Gillette (June 26): This insect has become rather abundant in sections of Denver and also in portions of the city of
Fort Collins, where it is doing very serious damage, especially to the American ash, the purple lilac, and the Carolina poplar.
I have been unable to find the scale upon apple trees or the
white lilac bushes. The lice hatched this month in Fort Collins
between the 18th and the 21st.
GIANT ROOT-BORER (Prionus laticollis Drury) New Mexico W. E. Emery (July 5): This insect is about 50 per cent nore
numerous than last year and in orchards inspected where this
insect occurs there is from 25 to 50 per cent damage in Dona Ana
RED SPIDER (species unknown)
New York V7. H. Hart (June 23): This pest was first noticed in increasing
numbers on foliage of susceptible varieties this week. It is
more abundant on foliage of varieties free from downy covering.

places, and in a few localities it is causing the leaves to turn
PEAR PSYLLA (Psylla pyricola Foerst.)
Delaware J. F. Adams (May 25): In Camden this insect is numerous on pear
trees. (July 5): In Dover one or more orchards are badly
New York G. E. Smith (July 15): The pear psylla is dangerously abundant
in a few orchards in Orleans County, but most orchards are fairly
PEAR-LEAF BLISTER- ITE (Eriorhyes nyri Pgst.) New York C. C. Wagoner (July 15): In Ulster County these mites are found
in goodly numbers in several orchards.
G. E. Smith (July 15): The pear psylla is very abundant in Orleans County in orchards near Holley and Yedina. Increase is noted over
the past season.
Utah I. M. Hawley (June 15): This pest is more abundant than last year
in many places, but not very serious as yet.
PEACH-T7IG BORER (Anarsia lineatella Zell.)
Maryland J. A. Hyslop (July 15): The peach-twig borer has infested from
80 to 100 per cent of the twigs in eastern Montgomery County.
California California Veekly News Letter, Vol. 5, No. 13 (June 30): A noticeable decrease in the prevalence of the peach-tvrig borer is noted in
orchards in the Buroank and Lankershim districts of Los Angeles
County, as a result of spray applications made last fall for this pest. Orchards which were badly infested last season show from
60 to 70 per cent decrease in infestation as compared with the
GREEN PEACH APHID (Yvzus Dersicae Sulz.)
New York G. E. Smith (July 15): This aphid is found more generally than
usual in Orleans County.
BLACK PEACH APHID (Anuraphis persicae-niger Smith)
California Roy E. Campbell (July 12): The black peach aphid is reported by
horticultural inspectors to be particularly nuirerous this season
in the San Fernando Valley. Growers are spraying with nicotine

Marleau, County Horticultural Inspector stationed at Glendale,
reports that the black peach aphid is particularly numerous this
season on orchards in Glendale, Burbank, and Lankershim districts.
SHOT-HOLE BORER (Scolytus rugulosus Ratz.)
New York G. E. Smith (July 15): This borer is destructive in Orleans County
to trees injured by the peach-tree borer.
Pennsylvania S. Y1. Frost and E. M1. Craighead (July): The fruit-tree barkbeetle, Scolvtus rugulosus Ratz., is doing considerable damage to
young cherry shoots in certain orchards in Adams County. The work
of these beetles resembles the work of the oriental peach moth,
but the cavities are much smaller. The injury thus far has been
noted only on sweet cherry. This type of injury has previously
been noted in literature but is not commonly found.
Alabama W. E. Hinds (June 30): Winter injury to pecans and young fruit
trees was severe and is being followed by bark-beetles. These include the fruit-tree bark-beetles in peaches and a species in
PEAR AND CHERRY SAWFLY (ealiroa cerasi L.)
Indiana B. A. Porter (June 7): This sawfly is defoliating cherry trees

cherry aphid was reported doing injury during the third week in
AN ANTHICID BEETLE (Notoxus talpa Laf.)
Michigan R. H. Pettit (June 28): I received word today fror F]iles, F'ich.,
that a beetle, which Mr. Gentner identifies as Notoxus tala Laf.,
has been riddling the fruit of sweet cherries and doing some injury
to sour cherries. The owner states that it was Aedaasaryt6p,',ik
the fruit of some trees in order to save it.
PLUM CURCULIO (Conotrachelus nenurhar hbst.)
Maine E. r. Patch (June 27): This insect is reported from Portland
attacking Governor Wood cherry.
Connecticut E. M. Ives (June 22): This insect is reported from Feriden attacking apples and plums, and more abundant than in an average year;
frequent sprays ord 'ingw a day or two apart have given some good
New York G. E. Smith (July 15): In Orleans County this insect is bad near
woods and in neglected orchards.
C. C. Wagoner (July 15): This insect is abundant in general in
Georgia 0. I. Snapp (July 16): No eggs of the second generation have been
deposited to date, and it now appears as though the entire Georgia peach crop will move this year without injury from the second brood of curculio larvae. About 4,500 cars of peaches have been shipped
to date from Georgia this year, and all of the crop has been remarkably free from "worms." The quality of the fruit this year is the
best that has been grown in Georgia since 1918.
RED SPIDER (species undetermined)
Ohio E. V1. Mendenhall. (July 3): Several raspberry plantations are badly
infested with red spider in the Dover district west of Cleveland.
This pest is doing considerable damage to the leaves of the raspberries.
BLACKBERRY CROWN-BORER (Bembecia rarginata Harr.)
Colorado C. P. Gillette (July 18): The blackberry crown-borer has recently
been reported to this office by County Extension Agent George R.

IMPORTED CURRAN 1TORM (Pteronidea ribesi Scop.) New York C. C. Wagoner (July 15): This species is general and quite des* tructive in some patches in Ulster County.
Nebraska M. H. Swenk (July 1): Young larvae of the second brood of the
imported currantworm were noted at work on currants during the
last week in June.
FALL WEBTORK (Hyphantria cunea Drury) GeaorgiA 0. I. Snapp (July 11): The fall webvrorm appears to be more abundant on pecan trees this year than normally. Numerous colonies were
observed on pecan trees today while riding through a section of
Louisiana Ti.R. Jones (July 2): Indications are that the weoworm, Hychantria

Society on this date T. F. Catchings, of the U. S. Bureau of Entomology,
reported the finding in New Orleans of what appeared to be Scutellista
cyanea, feeding on the "black scale," Saissetia oleae. I have since
been informed by Ed. Foster that this identification has teen
verified. It is interesting to note that this is the parasite
that, literature states, was sent to Dr. H. A. Morgan, then located at Baton Rouge, during 1898 by Dr. L. 0. Howard. So far as known,
there are no records of its being taken in the field in Louisiana
until recently. It is possible that its occurrence here is due
to the introduction in 1898.

about 50 per cent infested and replanting was necessary. They were planted right after a rainy period, when the ground was quite moist.
COVTPEA CURCULIO (Chalcadermus aeneus Bo4.)
Kansas J. R. Horton (July 6): Adults of the cowpea curculio continue to
puncture the stalks, and doubtless are depositing their eggs in
large numbers at this time. The greatest number of weevils to a
plant was 8, the average about 3. A few were found on cantaloupe.
MEXICAN BEAN BEETLE (Eilachna corruota Muls.)
South Carolina J. A. Berly (July 16): This insect has been forwarded to this
office from points in Oconee, Lickens, and Greenville Counties,
apparently spreading more than last year.
Alabama V. E. Hinds (June 30): The Mexican bean beetle taken at Auburn
May 8 has died after having deposited about 400 eggs in seven egg
groups. These eggs have practically all hatched. No sign of
the beetle has been reported in fields in Lee County, but undoubtedly such infestation occurs.
New Mexico R. L. Middlebrook (July 11): For some unknown reason the bean
beetle has not appeared in the southern half of this State in any
numbers and the bean growers of the Yesilla Valley and other southern valleys have had no trouble to date. Usually at this time of
the year there are many inquiries. Owing to the fact that few
inquiries were received an investigation was made and it was found that there are few insects in comparison with last year and former
years and practically no damage is resulting so far. (July 16):
Only a few larvae have appeared so far. The first brood is behind
time. Few eggs mature. Very few batches have been laid in
comparison with former years at Dona Ana. The string bean crop
will be off before much damage can result, but the Pinto may get
PEA APHID (Illinoia i Kalt.)
Michigan R. H. Pettit (June 2): Mr. Harman visited the Paw Paw and Cassopolis
region to examine the pea-louse situation and finds that the large
number of plant-lice on alfalfa has dwindled very markedly indeed.
he rings batK pe:imens of ladybirds, of Lysiphlebus, of another
hymenptc~~.~3 onarsit-e, and a fungus disease, Fmrusaapidis. I also receiv-d 3cizriens of alfalfa bearing plant-lice killed in
large nu -e.'s :)y this latter fungus disease. I also received word that a large number of plant-lice are appearing in the pea canning
region north of Grand Rapids.
Indiana J. J. Davis (July 16): The pea aphid was abundant and destructive
to canning peas at 2abash.
Wisconsin J. E. Dudley, Jr. (June 25): Ladybird beetles are destroying large
numbers, syrphid flies are just getting a good start, and funus
disease is of no importance as yet. Aphids are extremely abundant
in some fields of late sweet peas. As many as 800 have been collected
in five sweeps of a net.
Iowa Fred D. Butcher (July 14); An aphid,evidently the pea aphid, was
found killing sweet peas on this date.
Vebraskd 1K. H. Bwenk (July 1): The last two weeks in June were characterized
by an unusual abundance of aeh1iis of several kinds. In the flower
gardens the pea aphid was complained of as doing much injury to
Utah I. MK. Hawley (June 23): Although this plant-louse has been abundant
on clover and alfalfa this year, it has not been found in serious
numbers on peas up to date. There has been some damage to alfalfa.
New Mexico R. L. M iddleorook: This insect has been reported from Vesilla Park.
STRIPED CUCUMBER-BEETLE (Diabrotica vittata Fab.)
New York C. R. Crosby (July 10): This insect has been reported from Woodridge
attacking cucumbers. Insects have been received.
G. E. Smith (July 15): This species is reported from Orleans County
as abundant in gardens.
Wisconsin Leslie Herzog (June 30): This species is reported attacking
cucumbers from Wisconsin.
Missouri L. Haseman (June 27): Reports are being received daily concerning
the cucumber beetles. Reports thus far have come from central and
southern Missouri, mostly, and the beetles seem to be as prevalent
as last year.
Nebraska VK. H. Swenk (July 1): The striped cucumber-beetle began serious
injuries to cucurbits about the middle of June,
A CUCUBER BEETLE (Diabrotica tricincta Say)
New Mexico R. Middlebrook (July 13): Reports from the eastern half of the
State indicate that these beetles are doing much damage to cucumbers,
cantaloupes and watermelons.
MELON APHID (Aphis eosspii Glov.)
Indiana J. J. Davis (July 16): The melon aphid has been unusually abundant
on cantaloupes in the southern part of Indiana.
Iowa Fred D. Butcher (July 14): Aphids are very generally present on
cucumbers, ratrmelons, and cantaloupes. Ladybugs and syrhids
are fairly plentiful.
California Roy E. Campbell (July 12): The melon aphid is appearing in various
fields on single plants, but infestation is scattered and damage
ONION MAGGOT (Hylemyia antiQua 1eig.)
Michigan W. L. Ward (June 6): The onion ragot is reported present at
Oregon E. A. Hayes (June 1): Large acreages of onions at Salem, are being
damaged by this pest.
WIRE70RS (Agriotes mancus Say and Kelanotus sp.)
Indiana J. J. Davis (July 16): Wire,::orms were reported destroying onions
near Albion in the northeastern part of the State. Investizat ion July 2 revealed tw;o species involved. One company reports losses arounting to from 15, o00 tc -(),0C0. Wireuo'rs of all ages were
found. All of the ground, which is ruck, is well drained, but much
of it is new ground, an-d the .ir :orms were on the "hole more destructive and numerous onr. the newer ground, as might be expected.
It was inttreocing to note tat ':kere the seed row was rolled when seed was plen;d the on.i.os ca-e up better and rsde a much greater
g"owvth than sewhe:-e and L. a result -rere least injured. The wireworms a>pearAd aou'; the oi lJe of June, at which time the plants in the r- s no t rolled -ere much sirller and the small amount of injury
to ,one rlans was much rore severe than on the larger plants in the
rolled rc:s; in fact the rolled rc'rs were cnparatively little
damaged. From all data that could be gathered, comparatively little injury would have resulted, except possibly in the newest ground, had
the seed rows all been rolled after planting.
193ONION THRIPS (Thrips tabaci Lind.) Indiana C. R. Cleveland (June 21): The onion thrips are beginning to appear
on young onions at Munster, Lake County, on this date.
SUGAR-BEET WEB17TORM (Loxostege sticticalis L.) South Dakota A. L. Ford and H. C. Severin (July 5): A serious outbreak occurred on the Cheyenne River in Fall River County, where the worms took
practically everything in their path. These were successfully controlled by poisoned bran mash.
Utah I. M~. Hawley (June 23): A few fields are infested and growers are
starting to spray.
SUGAR-BEET ROOT-MAGGOT (Tetanops aldrichiHendel) Utah I. M. Hawley (June 23): Flies are out and depositing eggs now.
They are not very abundant, and not much damage is expected.
PALE-STRIPED FLEA-BEETLE (Systena taeniata v. blanda Mels.) Michigan R. H. Pettit (June 25): Systena blanda is making trouble again on
beets, both on sugar beets and on mangels. They also attack beans.
SPINACH LEAF-4MINER (Peromya hyoscyami Panz.) New York G. E. Smith (July 15): This species is reported attacking beets
and Swiss chard in Orleans County, with the statement that it is
bad in gardens.
Delaware C. 0. Houghton (June): Beets are badly infested by this leaf-miner
at Newark this year.
MEALY PLUM APHID (Hyalopterus arundinis Fab.) Delaware O. Houghton (June): This species is appearing in large numbers
this year at Newark. There were very few last year.
DISONYCHA N, SP.
Porto Rico George N. Wolcott (June 25): This common pest of beets and hmaranthus
spp. had bitten holes in the leaves and killed a large patch of weed, Phil er:s :re +us L., growing around a water-hole. Blackbirds,
Hol~o salu.s br;,h ierus Cassin, were feeding on the beetles.
ASH-GRAY BLISTER-BEETLE (Macrobasis unicolor Kby.) Maine E. M. Patch (July 20): This insect is reported from Dodge Pond,
Camp Rangeley, as ruining Swiss chard, by Frank L. Badger.
:aine E. M. Patch (July 13): This species has been reported from Ponmouth
attacking sweet corn; I didn't see specimens, but the common species
in that locality is Agriotes mancus Say.
Missouri L. Haseman (June 27): Complaints are still being received regarding
wireworms, more or less in scattered vicinities over the State. Utah I. M. Hawley (June 12): Wireworms are doing lots of damage to
tomatoes in a few fields in Davis County,
ZEBRA CATERPILLAR (>arestra picta Harris)
Indiana H. F. Dietz (June 22): The zeora caterpillars are very abundant in
and around Indianapolis. This is the first time since 116 that
this insect has oeen abundant.
NUTTALL'S BLISTER BEETLE (Lytta nuttalli Say) North Dakota R. L. Wester (July 13): This species is more than usually common
on potatoes and beans.
Utah I. M Hawley (June 15): This species is very destructive in Davis,
Salt Lake, and Juab Counties. This small milliped feeds on everything and is spreading farther each year. It even kills out the
weeds where it is abundant.
BANDED FLEA-BEETLE (66tena taeniata Say)
Indiana J. J. Davis (July 16): The pale-striped flea-beetle which was
reported damaging corn at West Point and Goodland was later reported from other localities. WVithin the past week this species has
been destructive to late canteloupes and cucumbers just coming
through the ground at LaFayette.
SOUTHERN FIELD-CROP INSECTS
BOLL 17EEVIL (Anthonomus grandis Boh.)
General B. R. Coad and assistants: The boll weevil survey up to July 20
Distribution indicates that the weevil has appeared in the cotton fields over
practically the entire Cotton Belt. The present limits are within
a line extending from Hidalgo County, in southeastern Texas, in a
northwesterly direction through Bexar County to Cole County and
Mitchell County, thence eastward to Fontague County, in the northeastern part of the State, thence across the State line in a northwesterly direction to Tillman County, Okla., thence northeastward
to the east-central part of the State in Okfuskee County, thence eastward into north-central #rkansas through the southern part of
Polk County, to the northeastern part of the State in Sharp County,
thence across the M.ississippi River to the northwestern corner of
Tennessee in Obion County, thence in a southeasterly direction
through Decatur and Hardin Counties and along the northern border
of Mississippi and Alabama, across the northern part of Georgia,
including the entire State of South Carolina and northeasterly
through Cleveland County, h. Car., and eastward across this State
through Iredell, Stanly, Moore, Cumberland, and Wayne Counties, covering the southern third of the State. The region south of
this line is generally infested.
Alabama W. E. Hinds (June 30): There is a very heavy survival of boll
weevils throughout the southern half of two-thirds of the State, and it may be also through the northern part of the State. In some counties weevils are reported as being more nunrerous in the
cotton fields at the time the squares begin to form than ever
before. At Auburn in some experimental plat work we are finding
from 50 to 100 weevils per acre at the time squaring begins on land
that has not been in cotton during the past six years, which indicates an unusually abundant movement from cotton field areas to
newly planted cotton fields, I think the heaviest I have ever known.
COTTON APHID (Anhis gossypii Glov.)
Georgia 0. I. Snapp (July 15): Cotton aphids have been observed in numbers
on cotton at Fort Valley.
COTTON CUTrOIRM (Prodenia ornithogal!i Guen.)
Louisiana T. H. Jones (July): Larvae %nere sent in from Pleasant Hill on
July 3 and from Long Bridge on July 6.
BOLLP-O (Heliothis obsoleta Fab.)
Louisiana T. H. Jones (July): Larvae were received from Dubberly (7ebster
Parish) on July 10 and from Grant Parish on July 14.
COTTON SQUARE-BORE (Uranotes melinus Huebn.)
Louisiana T. H. Jones (July): Larvae were sent in from Pleasat Hill
on July 3 and from Long Bridge on July 6.
Porto Geo. N. Wolcott (June 25): For the past two years these beetles
Rico have been reported as injuring cotton at Quebradillas. This
year large numbers were found in spider nests anid cu:-rled-up
leaves of a number of bushes on the beach at Arecibo. An
extended examination of many cotton fields, both near by and
throughout the cotton district, near the beach and back in the
bills, failed to discover any of them on cotton.
Louisiana T. H. Jones (July): We received letters on July 2, 4, and
6 from Gloster complaining of injury by a caterpillar that
"seems to stay on the under-side of the leaf of cotton, and there is always present a kind of web." The corresp1ndents reported considerable damage being done in the section and
it was reported that one farmer was applying calcium arsenate
for control of the worms. Two larvae were sent in.
GARDEN WE7ORM (Loxosteee similalis Guen.)
Arkansas T. E. Holloway and B. R. Coad (July 12): D-ipht Ikaly,
Associate Entomologist, Arkansas, reports in the press of
July 8 the presence of the garden webworm. Reports reaching him indicate that the insect is doing considerable damage to
cotton in the vicinity of Roland.
COTTONWORMI (Alabama argillacea Huebn.)
L6uisiana T. H. Jones (July 6): Two larvae, practically full-grown,
were noted in cotton field at Baton Rouge.
Texas T. C. Barber (July 14): In regard to the appearance of the
cottonworm in the Brownsville section, I would state that
it has been in this section for -ore than the past month. The
first occurrence of which I heard was on last June 8, when it
was reported to be present in the vicinity of Rio Dendo. On
June 10 it was reported from several localities in Hidalgo
County. The first apeeimens which I saw personally in
Brownsville were on the Piper Plantation, 6 miles east, on June 14, but the plantation men told me that they had been
there for about three days then, and poisoning operations
were just bi;ng ccmesnced on a large scale. Towards the end
of Jre 'colar weather with cloudiness and frequent rains, which washed off the greater portion of the poison almost
as soon as applied, resulted in an outbreak of the worms which has absolutely got beyond control. During the few
days I was away on my trip nearly all of the cotton in
the Valley was defoliated, It is rather difficult to estimate what the actual loss from the attack will be,
since a large portion of the cotton crop is already opening,
several hundred bales a day being ginned in the Valley.
'hile the late cotton will be severely injured, the loss
will be partially offset by the boll weevil loss which
would have been experienced in the absence of the worms.
At the present time the outbreak of the cotton caterpillar extends from Brownsville along the coast as far as Liberty
County. Inland the northern limit of severe injury coincides
just now with the main line of the Southern Pacific Railway.
T. E. Holloway and B. R. Coad (July 12): The cotton leafworm
is reported as present in cotton fields in the vicinity of
Nacogdoches, the demand for arsenicals being stimulated there.
Ged. A. Maloney: Farmers of Carthage, Panola County, report
the presence of the cotton leafworm on July 5. Also the
State Entomologist reports through the press of July 15 an
unusually heavy infestation of leafworm throughout southern
Texas as far north as Travis County.
Arkansas Dwight Istly (July 20): The cotton leafworm was collected at
Forrest City, St. Francis County, on July IS*
Porto Geo. H. Wolcott (June 25): One live pupa was found at Hatillo,
Rico one empty pupal skin at Garrochales. These are the first
records this year of Alabama in Porto Rico, not a trace of
it having been found at Boqueron two and four months ago
after the outbreak of last fall and winter had been eliminated
by Chalcis incerta Cresson.
Connecticut John Fay (June 22): Cutworms are attacking tobacco at
Portland. They are much more destructive than in an average
year with 15 per cent damage. Poisoned-bait, hunting for worms by hand, and poisoned plants are the remedies used.
TRUE WIREUI ORMS (Elateridae)
Kentucky A. C. M:rgan (June 21): At Lexington some fields with 50
to 60 per cent infestation have sufficient injury to
require 10 to 15 per cent resetting. Practically every
field-; has some infestation.
TOBACCO BUDWORM (Heliothis virescens Fab.)
Georgia A, C'- Morgan through T. E. Holloway (July 10): This pest is
very general around Tifton.
Louisiana T, Ho Jones (June 21): During a visit to the Perique tobacco
section, St. James Parish, larvae were noted to be common,
especially on shoots that had come up from plants in fields already harvested. The county agent believes this to be the
most important insect pest of tobacco in this section.
TOBACCO SUCKFLY (Dicyphus minimus Uhler)
Florida F. S, Chamberlin (July 14): This insect is very abundant at
present. The tobacco crops were harvested in time to prevent
A WEV,7ORM (Acrolophus popeanellus Clem.)
Tennessee A. C. Morgan (June 21): Damage occurred in only a few fields.
The infestation in the worst fields ran as high as 9O per cent,
Louisiana T, H. Jones (June 21): During a visit to the Perique tobacco
section, St. James Parish, hornworms of various sizes were
noted to be fairly common, P, sexta was more numerous than
P, euinquemaculata. The county agent reports that hand-picking is the only remedy used, though the larvae cause severe injury
in some fields during some years,
RICE STALK-BORER (Chil plejadellus Zinck.)
Louisiana J9 W, Ingram (June 26): Both the larvae and pupae of the rice
stalk-borer have been found in the tall grass, commonly called bull grass, growing near the rice fields at Crowley. No stage of the borer has been found in the rice fields up to this time.
SUGAR-CAE BCORR (Diatraea saccharalis Fab.)
Louisiana J. W7. Ingram (July 20): I visited a field of headed rice 2
miles west of Rayne, The field was about 1 per cent infested with moth borers, The borers were more numerous in the rice
on the higher land and on the levees. No rice stalk-borer were
found in this field.
RICE WATER-WEEVIL (Lissorhootrus simolex Say )
Louisiana J. W. Ingram (July 21): The rice ;iater-.7eevil has been doing
its usual amount of ia- .his year. The damage is mcat
nnticeable along water furromand deeply flooded portions of
FALL T7WEBWORM (Lan~h--rma fru1inerda S. & A.)
Louisiana T, E. Holloway and W. E. Hal#;y (July 5): Large larvae of this
pest are on nearly every plant in some ports of a rlantation
near Nexw Orleans. The caromill recover, however, from the
damage so far inflicted. There is some evidence of a braconid
parasite which may hold the species in check. The season has
been wet and cool.
SUGAR-EANE BORER (Diatraea saccharalis Fab.)
Louisiana 2, E. Holloway and W. E, Haley (June 25-26): Considerable numbers
of young plants killed by this pest were found in szare ficlJs,
The damage is not so great at present, but it indicates ce-rious
damage later in the season. Many egg clusters of the o.r-cane borer were found, most of v7hich were parasitized by Tr';crmlma
ROUGH-HEADED CORN STALK-BEETLE (Ligyrus (Euetheola) rucicers
Mississippi R. W, Harned: We are still receiving many complaints in
regard to L. runiceps. This insect has apparently d0one a large
amount of lamage this year to corn and sugar cane., The complaints
are still coming in almost every day, but are not as numerous
as they were a month ago.
bouisiana T, H. Jones (June 25): A beetle and stalk of sugar cane showing
injury by this beetle were sent in by the county agent from
FOREST AND SHADE-TREE INSECTS
PERIODICAL CICADA (1':bicenr seotendecim L,)
BROOD XIV (SEVENTEEN-YEAR RACE)
New York J, J. Levison (July 17): The 17-year locust was exceedingly
abundant on an estate at Cold Spring Harbor and elsewhere
in the vicinity of Sea Cliff, L. Is They were so think that we
shoveled them up in pailfuls,
Pennsylvania P. R. Myers: A few adults,numerous papal skins, and chimneys
of this insect were observed along the mountains near Duncannon,
Perry County,-on May 27.
S, W. Frost (4ef): The 17-year locust was found at many
places in Adams Countyr Only in a few places has the injury
been fou-nd serious to orchards and in these places the injury
was principally along woods, Both peach and wuple were attacked
in such cases. The locusts are quite numerous in the woods and the dead leaves from broken twigs are very conspicuous.
Parker T. Barnes (July 10): Reports indicate that this brood
appeared over central and southeastern Pennsylvania, west
to Franklin, Huntingdon and Clearfield Counties, and notth
to Clinton, Lycoming, and Luzarne Counties.
Ohio T. H. Parks (July 19): Brood XIV adults have seriosuly injured
some young orchards in Lawrence and Scioto Counties, These
orchards were usually closely associated with native timber.
Forest trees now testify to the visit of the cicadas.
Kentucky A. 0C. Morgan (June 21): A belt of a mile or more at Bloomfield
and Hodgensville was noticed June 14, numerous enough to drown
the sound of a passing auto.
A NW PEST (Phyllobius oblonus L,)
New York R. E. Horsey through M. D. Leonard (July 17): A Auropean
beetle on elm was common June 2 to 9, the last two being found
July 6, It did little damage and we did not spray for it.
I only saw it on thtee American elms 50 feet or more tall,
about 40 years old, which were here before this became
park property. Across the road it a large collection of crab
apples from northeastern Asia and North America where no
$race of this insect has been found.
M. Do Leonard: On June 2 Mr, Horsey sent specimens to this office with a statement that the beetles were very abundant
and doing some damage to the leaves of elm trees in Highland
Park by eating holes in them. The insect was determined by Dr. Schwarz, who states that this snout-beetle had not
been found before in this country. It is recorded from England
as feeding upon apple buds, and it is thought that there is
some likkihood of its developing into a pest should it become
established in this country.
F4LL WEBWORM (Hyphantria cunea Drury)
Indiana Bo A. Porter (June 21): An outbreak of this species seems
abolf to occur in the region about Vincennes, Many nests are
already in evidence.
Kansas Geo. A. Dean (June 22 and 25): Infestation occurs at Edwardsville
and Manhattan on elm and box elder. The webworms are more abundant than in an average year. From May 1 to 116 it was
rainy and coll 4id from May 16 to 25 hot and getting dry,
FOREST TENT-CATERPILLAR (Malacosoma diestria Huebn,)
Massachusetts At F. Burgess (June 30): Several reports indicate that this
insect is common over most of New England. N6 serious defoliation
is reported, however.
Idaho Ja C, Evenden (June 26). Throughout the northern part of the
State the wild cherry is being defoliated by this insect. The attack in many places spreads to other native shrubs, but the
favored host plant is apparently the wild cherry.
Oregon A. Lo Lovett (June 22): This has been the season for an
unusual outbreak df tent-caterpillars. Here in Oregon they seem to come in rather definite seven-year cycles. In 1915
they were very bad, but were practically cleaned out entirely
by a Tachinid parasite in 1916, Last year they were serious
and this year the climax of the infestation is here, and again
we find somewhere in the neighborhood of 90 to 95 per cent
parasitism by this Tachinid fly, I note that the eastern tentcaterpillar likewise is unusually prevalent this year. Another
interesting thing to me in connection with these caterpillar
outbreaks is the practically absolute absence of hymenopterous
BAGWORM (Thrido]2teryx epehemeraeformis Haw,)
Georgia O, I. Snapp (July 20): Bagrorms are unusually abundant in this
section this year# attacking principally arborvitae and other evergreens, Some arborvitae have been completely defoliated.
Arsenical spraying had to be resorted to,
Indiana Jo Davis (July 16): Bagworms have been destructive to
arborvitae, cedar, and other tre-es in the southern fourth of
the State, reports coming in the last of June and early in
Kansas J. W. McColloch (July 20): This species is attacking cedars
in Wabaunsee, Shawnee, and Osage Counties in the no-theastern
part of the State, and in Greenwood, Jiison, and S-Lrmrer
Counties in the southeastern part, This inE ct is so'rewhat
more abundant than in an average year, bsdly defoliati'ng
trees in some places. The weather has been warm with high
ELU SPANWCRM (nomos subsimnarius Huebn.)
New York Co R. Crosby (July 9.10): A great flight of moths was observed
from Newark to Niagara Falls on the 12th. A few came to lights
at Lilly Dale.
Ohio T. H. Parks (July 19): These larvae were ntumerous on shade
trees in East Liberty, Logan County, during June and caused
defoliation, Adults were appearing during early July,
Indiana J* J, Davis (July 16): Additional records have been received
of the snow-white linden moth. Infestation occurred in a strip
several counties wide through the central part of the State, east and west from near the Illinois line to the Ohio State
line. The white moths were reported as being abundant in
several sections July I.
H, F, Dietz (June 22): The snow-white linden moth is very abundant this year in the northern two-thirds of the State.
Ash, basswood, hard maple, beech, elm, hacLiberry, water beech,
and ironwood are being seriously defoliated. The cate~inrllars
at this time are almost full-grown. Although last year between
50 and 75 per cent of the larvae collected around Indianapolis
were parasitzed by Pipla inquisitor (?) and an undetermined tachinid, this has not reduced the numbers of the pests this
ORIEnTAL MOTH (Cnidocampa flaveecens Walk.)
Massachusetts A, F. Burgess (June 30): This insect is abundant in the
vicinity of the Dorchester and Roxbury districts of Boston and
quite abundant in the Norfolk Downs district of Quincy, also
common in Winthr~p. It is found on various shade and fruit
trees, though it seems to be most common on Norway maple.
ARBORVITAE LEAF-MINER (Argresthia thuiella Pack,)
Maine E? M. Patch (July 20): This pest is causing consternation in
nurseries and to landscape gardeners. I judge the work is done
for this season.
Vermont Geo. M. Codding (May 29): On a trip through Vermont last
week I noticed that a leaf-miner was rather common on the
hbmlock and have also found it around New York.
Connecticut Geo, M, Codding (May 29): 'We found a leaf-miner in Stamford doing considerable damage to an arborvitae hedge.
New York M. Do Leonard (July 7): This insect has been common in
Rochtstdrr parks for years but is not injurious. R. E, Horsey
reports the finding on July 2 of one chrysalis and two
ASH BORER (Podoeesia fraxini Lugger)
North Co No Ainslie (June St): Ash trees 15 to 20 feet high are
Dakota riddled with larval mines and are being killed. It also
attacks lilacs. Twenty and more empty pupae were observed
extending from a single small ash tree. The trouble seems
local, neighboring t-owns free.
ASH iPHID (Pemphigus fraxinifolii Thom.) Nebraska M. H. Swenk (June 15-July 1): The last two weeks in June
were characterized by an unusual abundance of aphids of
several kinds. Reports of the curling of the ash leaves by
the ash aphid were received.
WOOLLY BEECH APHID (Phyllaphis a i L.)
New York M. D, Leonard (June 20): The walks in the town of Cannister
were reported spattered with honeydew. Beech trees are
R. E, Horsey (June 27): On vurJa and other small European
beech trees at Rochester this insect is very numerous on the
underside of the J aves. It is sprayed and controlled with
soap and Blackleaf 40, It was noted about June 12 and sprayed
about a week later.
Indiana H. F. Dietz (June 22): This is a bad plant-louse year, this
species being very abundant on the leaves of the native
beech .(FaAis Prandifolia Ehrhart), Leaves of large trees are
badly curled by this pest around Indianapolis.
SPEAR MK (Eulypa hastata L.)
Maine E. M* Patch (July 20): Rheumaptera hastata is swarming all
over the State. I am besieged with alarmed questions.
Carl Heinrich: Referring to B. hastata Linn, all the data
we have on this insect are to be found in Packard's Fifty
Report, page 503, under the heading Rheumptera hastata. The
caterpillar has several food plants-Betula, Mlyrica, sweet
gale, wax myrtle, huckleberry, and Rhododendron are recorded.
The species overwinters as pupa, the moths issuing in spring.
There are probably two generations a year.
New T. E. Snyder (July 26): The only record in this office of
Hampshire this insect reads, "moths which have been found in great
numbers this summer in our timber holdings in northern NH."
BRON0ZE BIRCH BORER (Agrilus anxius Gory)
New York M. D, Leonard (July 17): All birches of the cut-leaved variety
observed in the city parks and streets of Albany are dying or have died, The City Forester reports that this city has lost most of its finest cut-leaved birches from this insect.
BOXELDER APHID (Per iphyllus negundinis Thos.)
Utah I. M. Hawley (June 1)-: The boxelder aphid is abundant in
Davis, Salt Lake, and Utah Counties.
A LE AP-,A7L~ gA
Utah I. M. Hawley (June 13): The caterpillars of a leaf-roller
