OUTSTANDING ENTOMOLOGICAL FEATURES IN TEE UNITED STATES FOR THE MONTH OF MAY,1925

This month has been marked by more widespread cutworm injury than any similar period during the-past four years. Notes on the destruction of large patches. of pasture and corn in Ohio, Iowa, Missouri and Kansas, and reports of serious cutworm damage in northern Michigan, Connecticut, Indiana, Illinois, Idaho, and California have been received. The outbreak of the army cutworm in the Middle West has about terminated, heavy flights of the moths having been observed in Texas and pupation of larvae reported from Montana.

The chinch-bug situation has not materially changed since our last report, as is also the case with Hessian fly, with the single exception of Kansas where thousands of acres of wheat have been plowed under on account of the heavy infestation,
Flights of the armyworm moths have been observed in Indiana and Illinois during the last week in April. Armyworm damage has already been reported from northern Indiana and also northern Illinois.

Telegraphic co,,umication dated May 27 has just been received from Alabama that larvae of the cotton worm are abundant near Corpus Christi. A note has also been received that on May 23 larvae were abundant in several fields near Brownsville, Texas. This is an unusually early appearance of this insect. In 1924 the first report was received from the Brownsville region on July 23; in 1923 the first report was received on June 8, and in 1922 on August 1. In 1921;the first lafvae were observed in Lowndes County, Ala., on August 26. The average date for the past three years for the first appearance at Brownsville was July 7. The present appearance, 42 days ahead of the average and 10 days ahead of the earliest appearance of this ineeet in the past three years, is of decided interest as the early appearance of the larvae of this insect is usually indicative of serio~is damage before the bolls are formed. We can also expect damage later in the season by.the moths attacking fruit in the Northern States.

The corn rootworm seems to be more troublesome than usual this year in the Southeastern and Gulf Region,

The pea aphid is reported as attacking alfalfa;and clover over a very broad region,-reports having been received from Connecticut, Michigan, Indiana, Illinois, and California.

The clover-leaf weevil seems to be very decidedly more prevalent this year than usual in Indiana, Michigan, and Iowa. It is also reported as causing somedamage in Maryland and Kansas.

Tent caterpillars are again proving very numerous in the New England and
Middle Atlantic States. A more restricted region of infestation is reported from Michigan.

Pear psylla infestation is general throughout the fruit sections of New York State.

The plum curculio has been materially retarded in the Georgia Peach Belt by dry 'weather. In Illinois and Missouri this pest is more prevalent than usual,
A limited but very serious infestation of'the black-lined cutworm in
blueberry plantation6in. M~ine is reported this month, single growviers suffering losses as high as'$12,000.

A species of Julus is assuming mqjor importance as a potato pest in northeastern Ohio.

Damage for the first time to activated crops by Eleodes omissa borealis
Blaisd., one of the false wirevorms,is reported from California.

A late report not included in this number of the Bulletin indicates that the Mexican bean beetle was taken in the field at Birmingham, Ala., March 30, three weeks earlier than in 1923 and 19214. By May 25 over 20 per cent of beetles had emerged in hibernation cages. The right infestation in this section is undoubtedly due to small number of beetles entering hibernation last fall on account of prolonged drought.

An interesting note of the gradual increase in destructiveness of the
garden fleahopper to truck crops has been received from the west coast 'of Mexico.

Two unusual pests of strawberries are reported in this number, one the raspberry fruit worm attAcking the youtg fruit in Connecticut, and the other a small beetle 3rachyvterolus valicarius, feeding on the blossoms in New York State. The latter was reported doing similar damage in New, York State in 1922 (ss I.P.S. Bulletin II, P.89, undqr Heterostom1s~pi1icarius L.

In the Sinaloa region of Mexico the corn earworm is reported as having destroyed a very appreciable quantity 6f the cannery peas, estimates running from 1 to 50 per cent in different fields. This is the first record that we have pf this insect being a serious pest to peas.

The camphor scale has been found for the first time in Vermilion Parish, Laa
The elm leaf beetle i6 reported as seriously infesting trees in Dayton, Ohio, where up to this time it has not been a serious pest.

A very serious infestation of a rose house in the vicinity of Philadelphia by the Surinam roach is reported in this lumber. In'one of the commercial houses in this vicinity approximately 30,000 plants have been girdled.












OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA FOR MAY,1925

The outbreak of Dendtoctonus monticola Hopk. in lodgepole pine at MartinmMo#ntain, B. C., has extended very rapidly since last year. During the control operations commenced this season over 25,000 infested trees have been marked for cutting.

An extensive outbreak of Dendroctonus beetles in spruce has bean discovered in the forests near Prince Rupert, B. C.

Control work conducted for the last two years on the pine bark beetle outbreak in the Aspen Grove.forest, British Columbia, where 300,000,000 feet of yellow pine was threatened with destruction, has resulted in the infestation being almost entirely removed. It is believed that'the success obtained is due in large measure7to the rigid enforcement of slash burning throughout the
yellow pind area.

Grasshoppers are not expected to cause any serious trouble in southern Manitoba during 1925.

An outbreak of the black army-cutworm Agrotis fennica Tausch., occurred over a limited area near Ottawa, Ont., during May. Some damage was done to clover
and p3eas, but the -outbreak was early checked by a- fungus disease which destroyed the majority of- the larvae.

The cricket, Anabrus lonies Caudell, is occurring in outbreak form at Kelowna and Vernon, B. C.

The leaf roller Cacoecia rosana. La is steadily spreading in the orchards-of the Saenich peninsula, B.C.

There was a heav',, deposition of eggs of the pear psylla, Psyllia
Pyricola Forst., in the orchards of the Burlington and Niagara districts., Ont., by the end of April.

GENERAL FEEDERS

GRASSHOPPERS (Acridiidae and Locustidae)

Georgia 0. I. Snapp (April 25): Grasshoppers have been unusually abundant
in several orchards at-,Montezama and Marshallville during the past
week. In some sectionsseverai orchards, especially in the lowlands, grasshoppers have. devoured or seriously injured .50 per cent hesh0e.
of the small green peaches.

Mississippi R. 7. Earned (March 11l): Reports have been received from Gulfport,
indicating that grasshoppers are causing serious damage to the flowers, shrubs, and& other plants in the cemetery at that place. From
the description given, this is probably the ork of the Southern lubber grasshoppe'r, Romalea microptera Palis. The grasshoppers are said to be rather thick on some of the lots in the cemetery
and collect in large numbers. on plants. It is reported that late
'in the afternoon the grasshoppers seen to seek shelter. (April 22):
A letter from a correspondent at Happton, Washington County, dated April 22, is as follows: "During the season of 1924 we had a very
heavy infestation of grasshoppers, from which we suffered heavy damage on cotton and soybean crops. They ate up absolutely, so
that not a stalk remained, about 40 acres of soybeans; and of cotton, many acres for considerable distances along ditch banks down into the
fields. We are now finding large numbers of grasshoppers hatching cut along the ditch banks; and this makes us fear the possibility of
heavy damage again in the 1925 season."

Minnesota A. G. Ruggles (May 13): On May 7 in Benton County we found that
the eggs of the grasshopper Camnula pellucida Scudd. had passed
through, the winter in good shape and some of the eggs were hatching.
All indications are that there will be several .outbreaks in this
part of Minnesota this year.

rkhoma E. Sanborn (May 7): Began hatching in southern part of the
State April 1 and in the northern part April 30. Belated forms are now hatching. They are 75 per cent more numerous than last
year.

J. L. Webb (May 12): G. A. Waloney, of the Tallulah Laboratory, sent in the following note: "Poison has been required to control
grasshoppers in Oklahoma."

Montana R. A. Cooley (May 1): Crickets were reported on April 8 as recently hatched and very ab-,ndant at Camnas Prairie, Sanders County. Damage to crops is expected. Am not sure of the species, either
Peranabrus scabricollis Thorn. or Anabrus simplex Ha1ld.

JITE GRUBLS (Phyllophaga spp.)

7isconsin S. B. Fracker (:ay 14): Phlophaa spp. turned up in large numbers in the spring plowing in central counties of this State.









ndiana J. J. Davis (May 25): In addition to the numerous reports of
white grubs turned up by the plow we have received a report on
iay 16 frcm Pushville that gru os were, destroying wheat. Specimens accompanied the report.

Webraska M. H. Swenk (April): Wits grubs have been complained of as destroying lawns in all the southeas-tern counties of the State, but especially from the t'6 souTher, tiers of counties lying between
the 97th and 99th meridians, where this sort of injury has been
especially heavy. ,

CUT0RMS (Noctuidae)

Connecticut W. E. Britton (,May 22): Cutworms are seemingly more abundant this
year on vegetable plants in Litchfield, Hartford, Tolland, and
Middlesex Counties.

Michigan R. H. Pettit (May14): I am getting word of an outbreak of climbing cutworms, both in the northern part of the fruit belt in the
Lower Peninsula and way up at vEwen in the Uoper Peninsula, and these reports tell us that the cutwornms are in runheard-of numbers. May
21): We have received some larvae from the Up-per Peninsula and,
while they all died overnie2t, I was able to determine them as
Noctua fennica Tausch. A letter received from the county agent at
Ewen also tells me that the economic loss has not been heavy because
there is not so much in the way of agriculture going on up there,
but the damage done to wild plants has shown possibilities that have alarmed the whole county. Another species of cutworms which is destroying two-thirds of the buds of some trees in Montcalm County near Stanton, is still undetermined. Probably c-ni7rum L. Mr. Gentner, who has just returned from Benzie County (Beulah), tells me that the species which is making a lot of trouble up there is something still
different.

Ohio G. A. Anner (May 15): Climbing cutworms have caused some damage
to buds of apple in Ottawa, Erie, and Lorain Counties. Adults
bred from larvae found feeding on buds of apple have been determined
by S. E. Crumb of the Bureau of Entomolorgy as Rynchagrotis cupida
CGrote.

H. A. Gossard (Tay 21): I saw pastures of 60 acres in Licking
County with hardly a spear of green grass left in them and 10-acre
patches of destroyed grass were common through two or three townships. I was told that there were several much larger pastures
in the same condition. In one pasture we found the worms had advanced in a solid front about 25 feet per day during a period of four days, eating everything before them. Counts of the number of wozrms per square foot on this advancing front were made from 3 square feet located at different points along the line and the
average was 172 cutworms per square foot. In a few cases the
caterpillars were entering fields of wheat and oats, destroying
these as they went.








-100

There was an outbreak near Colunmbus in 1886 very similar to the present one and it was estimated that year that three or four thousand acres of pasture was completely destroyed. I judge the damage this year will be as great or greater than
this. We saw patches of pastu1tie destroyed in Delaware County about 5 miles north of Delaware and this cutworm present. The
bacterial disease now working on them will in all likelihood
prevent a recurrence of the attack next year. Probably very
few of these worms will pupate.

Indiana B. A. Porter (May 21): More complaints have been received of
garden cutworms than usual from home gardeners.

J.J. Davis (May 25): Have been reported as destructive in gardens since April 30 from Indianapolis, H organtown, Laporte, and
Mi shawaka.

Illinois UT. P. Flint (M1ay 22): A few reports of cutworm damage have been
received, but the insects seem to be less numerous than usual.
All damage thus far noted was to early-planted corn.

Iowa C. J. Drake (May 7): Cutworms are very abundant this spring.
The W-marked, N~ctma c-nigru L., the bronzed, Nephelodes minians
Guen., the greasy, Agrotis ypsilon Rott., and the dingy, Feltia
subothica Hw7., seem to be the more common species. Several
records have been received from various parts of the State. One
farmer stated that he found as many as 25 cutworms in a square
foot of ground near a hill of corn. The bronzed cutworm has
started to pupate.

.Liesouri L. Kaseman (May 1-15): On May 12 most of the bronzed cutworms
were apparently full-fed. They are widely distributed over the central part of the State. Some report them destroying pastures
much like the armywow.

Nebraska M. H. Swenk (April): The outbreak of the army cutworm, Chorizagrotis auxiliaris Grote, reported upon under dates of Narch 26 and 31 and April 9, did not result as seriously as the enormous
number of cutworms present in the winter wheat and alfalfa fields threatened, largely owing to the cool, rainy weather that prevailed over the heavily infested counties during the early part of
A-or l. The winter wheat in many fields was damaged but, having
a good root system, continued to grow, while the weather held back
the activity of the cutworms and in most cases the wheat eventually got ahead of the cutworms. In the alfalfa fields there has simply
been a -partial loss of the first cutting of hay, without any important killing out of the plants in the old fields. If dry weather had prevailed after the damage started the loss would
undoubtedly; have been very severe as the cutworms were exceedingly
abundant. In one field north of Brandon, in Perkins County, a piece of sod measuring 4 by 5 inches was found to harbor 44 cutwo.ns in and under it. Another one, slightly larger, harbored close to 60 cutworms. In a field just north of Madrid, Perkins










County, 65 ciatworms- vere found in and -ander an old cornstalk
1ying on the grcund. These hordesj of -.-orms, ho'-Yever,, grad-ually reached.mt1rtr for the m-st '. .rt; vi thc-.it corrpletely destroying the 6-ow37-Tn) crcps, and theis-e are now racove:.ng, in large

Darirng LApr A.1 inj-ury by th-'.s crtworm a-ppeared more or less in couiities To the east of the he---,Ily irifecte,_1 a:ea, but the damage
has not beea important. The co,)ti'Les eFso~c i'.lly rey.pcrin injury
are Lincoln, Kearney, and Riffalo Coizitics, in~ the Platte Valley,
and are almost wholly related to damge in alfalfa fields. At
the present time complaints of injury by the a-my cutworm have
entirely ceased.

Mssissippi R. W. Harned (May 21): Inspector N. Dl. Peets with headquarters
at Laurel, Jor.3s County, reports -under date of Ma y 12 as follows:
1C~twomzare dcing considerable damage on cotton in this section."1 The. spezcimenn that he sent in vith is note 'nave baen identif ied

Don B. Whelan (May 7): T have received a number of specimens of
the army cutworm, Chorizagrotis auxiliaris Grote, from Jerome County
where they were injuring alfalfa. These specimens were sent in
by the extension entomologist.

Calif ornia A. 0. ta6rson (April 24): Cutworms are more abundant this year on
truck crops in Stanislaus County.






CEREAL AND FORAGE-CROP INSECTS



CHINCH BUG (Blissus leucopte s Say)

illinois W. P. flint (May 22): baminations during the last week have
shown chinch bugs even less abundant than was the case during
the latter part of April. It now seems certain that no serious
damage from the first brood of this insect will occur anywhere
in Illinois this season. The weather for the past month has been extremely dry, and conditions in general have been favorable to the chinch bug had sufficient numbers survived the winter.

.:issouri L. Haseman (May 12): In some fields in west-central Missouri farmers are reporting that the pest is already affecting the wheat
(overwintering adults). Mr. Wade has also observed several badly
infested fields of wheat.
:.1ississippi R. W. Earned (May 21): More complaints have been received in
regard to chinch bug injury to corn this spring than during any previous year for a number of years. Most of these complaints
have come from the Yazoo-Mississippi Delta section of the State,
that is, the northwestern part of Mississippi. All the complaints received have been in regard to the injury caused to corn.
Conditions have been very favorable for the increase of these insects, as during 1924 we had the longest drouth on record. This
spring there has also been much less than the average amount of
rainfall.

Nebraska M. H. Swenk (May 25): Chinch bugs are more numerous and more
widely spread over an area in southeastern Nebraska than they were
last year at this time. We expect heavier infestation arA more
loss this year than last.

Kansas J. I. -M1cColloch (May 21): Chinch bugs are abundant in the wheat
fields throughout the eastern two-thirds of Kansas, and are causing
so' e loss. Their injury is obscured by the heavy infestation of the Hessian fly. Climatic conditions have been favorable for the
bugs. Young bugs have been hatching during the past week.

HESSIAN FLY (Phytophaa destructor Say)

Illinois W. P. Flint (May 22): The Hessian fly spring brood is more abundant than was indicated by our reports last month. Recent examinations made by S. C. Chandler, in southern Illinois, and by J. H.
Bigger, in west-central Illinois, have shown a very high percentage
of wheat culms infested by this brood. At the present time the average culm infestation is close to 50 per cent in many fields, with early-sown fields running as high as 90 per cent. In some
cases late-sown fields show less than 10 per cent of the culms
infested. The figures given include all culms on plants examined
in whatever condition. In many cases where the infestation for
culms will run as hiph as 25 per cent, the damage is not great




-102-








-103

because of the fact that the infested culms are the smaller,
later, weaker ones which would never make heads in any case: Judging by present indication, the fly is practically all in
the ful21-grown larval or flaxseed stage. All vwheat is in a
poor condition owing to the very dry weather. Only 0.22 inch
of rain has fallen at Urbana during m~ay.

Iowa 0. J. Drake (May 7): The Hessian fly has been greatly reduced
in numbers and it is very hard to find specimens in wheat f ields.
Over 90 per cent of the farmers in the winter-wheat-growing section of the State cooperated in the Hessian fly campaign last
year.

-Tebras. .a M.H. Swenk (April): An inquiry into conditions in Johnson and
Pawnee Counties, made during the present month, showed that while there was considerable Hessian fly in volunteer wheat plants and
in drilled wheat sown considerably before the announced dates of
safe sowing, the wheat sown on or after the announced date of safe
sowing is practically uninfested.

Kansas J cColloch (May 21): Reports and surveys show that the
Hessian fly is present in damaging numbers throughout nearly all
the wheat-growing area of the State. Thousands of acres of wheat
have been plowed under. The second spring brood is just beginning to emerge and further damage is anticipated before harvest.
In many ways the present outbreak has been more destructive than
any previous one.

WIREWOPIIS (Elateridae)

Idaho Claude Wakeland (April 30): A toll of hundreds of acres of wheat
has already been exacted by wireworms in the irrigated sections.
Wireworm injury is so severe this season that we are planning making an extensive survey of Canyon County.

FALSE WIREORES (Eleodes spp.)

Idaho Claude 7akeland (April 30): The false wireworms are proving very
destructive to fall and spring planted grain in the dry-farming
areas of eastern Idaho.

7HEAT STPA 0PIi (Harrnmollta =andis Riley)

Kansas J. I. AcColloch (LMay 21): Samples of wheat infested by the strawworm have been received from Great Bend and Greenburg.

A ROOT APHID (Geoica sruamosa Hart)

Nebras.a M.H. Swenk (April): During the first week in April the whdatroot aphid, Geoica sounmosa, was found so abundantly on the roots of smartweed in a stubble field in Yuckolls County that the question was raised as to whether it would be safe to plant corn in
that field this spring. LBRAY
TATh pLANT BOARD











CLOVR MITE (BroX a raetiosa Koch)

Nebraska M. 1. Swen (May 25): This mite wvas swanning by the millions
during the first week in MaIy in a wheat field in Cheyenne County,
causing the wheat to die out in spots.

C01N

ARMYOPMQ (Cirphis unituncta Haw.) Indiana J. J. ravis (1.ay 10): First adults of this moth were noticed
April 25 at Lafayette. There has been cool weather since.
Adults were ag.in noticed the night of May 10. (May 25): The
armnyworm, Cirrhis uniuncta, has been reported (May 20) from several localities in Fulton County in northern Indiana. In all cases so far the worms were found in low lying meadow and
pasture land.

Illinois W.P. Flint (M.ay 22): A fairly heavy flight of armyworm moths
occurred in the central and northern parts of the State during the last week of April. Caged specimens laid unusually large numbers of eggs. The worms are just beginning to hatch in the field and one report of injury has been received from the northern -art of the State. The moth flight oas not as heavy as in
192- and although scattered damage is expected we do not look
for a serious general outbrck.
SPOTTED CTUC1FR BETLE (Diabrotica 12-punctata 5-.

South Carolina Philip Luginbill (May 18): A large field of corn planted on
bottom land was completely destroyed at Columbia. The corn
was planted about April 15.

Alabama J. :. Robinson (April 29): The southern corn rootworm is causing considerable destruction to corn that has been planted after the turning 6f vetch. This is one of our rather serious insect
pests following this highly desirable legme.

Mississippi R. W. earnedd (April 13): Although this insect probably always
causes considerable damage in this State each spring, this year
it seems to be more abundant than usual in certain places. Under
date of April 13 a large planter at Natchez sent one of these insects to thisoff ice, stating that it was ',working great damage to
stands of corn in the black lands of the swamp. They get into
the corn jus3t as it gets above the gorund. It has destroyed
the stand unon 300 acres for us."

SOT TIHZ C0E LFAXF BEETL (:Y7ochrous denticollis Say)

Mississippi R. W. Harned (April 11): A correspondent at Dahomy, in Bolivar
County, cent a number of beetles to rs on April 11 that have been
identified by J. I. Lancston as 1grochrous denticollis. The correspondent states that these beetles were on his ccrn and that he found








most of them in fields which have been in sweet clover for two
years. On April 23 another correspondent from the same town
sent in specimens of these beetles with the statement that they
were causing damage to corn.

SEED-CORN MAG-GOT (Hylemia cilicrura Rond.)

Ohio H. A. Gossard (May 22): The seed-corn maggot is very numerous
and is very injurious all over the State.

Illinois ". P. Flint (May 22): A few reports of injury about this insect,
accompanied by specimens, have come in.

BILLBJGS (Sphenophorus spp.)

Indiana J. J. Davis (May 18): TwoSchenophorus zeae beetles to nearly
every hill of corn. The corn is 1 to 2 inches high. They work on the stalks below the surface of the ground and kill the plant.
Present indications are that they will destroy a 25-acre field.
Specimens were submitted.

ansas J. W. McColloch (Hay 22): The maize billbugs have been found in
cornfields at Junction City and Ogden, in numbers sufficient to cause injury to the crop. This is the first time that this insect has proved troublesome in this part of the State.

RWIRE7 0RS (Elateridae)
indiana J. J. Davis (May 25): W7ireworms were reported May 21 from Orestes
where they are destroying corn in the bottom lands.

andas J. W. McColloch (May 21): Reports of wireworm injury to corn are
just beginning to come in from Bronm, Riley, and Sumner Counties.
Abundance as compared with an average year seems to be about the
sa.:e.

ALFALFA AND CLOVER

PRA EPHID (Illinoia pisi. Kalt.)

onnecticut B. H. Walden (May 14-20): Abundance this year much more on alfalfa
in Hartford, New Haven, and Middlesex Counties. The infestation
is worse where the plants suffered from dry weather in 1924 and where the plants were slow in starting this spring, due to poor
: drainage. From 75 to 90 per cent of the plants were badly injured. An owner in East Windsor plowed his alfalfa under to plant corn. At North Branford and West Simsbury many aphids
were killed by Enpusa.

:ichigan R. H. Pettit (M:ay 14): The pea aphid is reported as being very
-plentiful in some alfalfa fields.

ndiana J. J. Davis (April 30): Reports were received of injury to alfalfa
by thisinsect on April 28 and 29, from Decatur, LaPorte, and Knox.












All reports were accompanied by specimens and indicate considerable damage. All lots are accompanied by numerous ladybird beetle larvae and parasitized individuals. (May 7): The
county agents of Decatur, Elkhart, and Marshall Counties were in today and reported increasing injury from the pea aphid on alfalfa. Spots are dying out and in some cases entire fields
are threatened with destruction. Continued cool weather has
checked parasite activity.

Illinois W. P. Flint (May 22): A number of cases of intary to alfalfa
by this insect have been reported in the northern part of the State. The aphid reached the maximm about May 1 and since that time they have been practicall'y-cieaned out by parasites
and predators. In a recent examination of alfalfa it has been difficult to find living pea aphids, although parasitized individuals were numerous.

Nebraska M. H. Swenk (May 25): Several fields of alfalfa were badly injured by pea aphid in Dawson County.

Wyoming C. L. Corkins (May 12): The pea aphid h-ave just been received
from the-county agent at Caspdr, who states that these lice are
attacking small patches of alfalfa. Damge is slight, but severe
in spots.

California C. M. Packard (Yay 7): An extremely heavy infestation is reported in nearly all fields in the northeast portion of Antelope Valley, in the vicinity-of Roosevelt, about 9 miles northeast of Lancaster.
Illinoia -isi has been present all spring but is now much reduced by coccinellids and syrphids. The first cutting was completely
lost and in some fields a portion of the plants have been actually
killed.

R. E. Campbell (11ay 8): The attack of the pea aphis on alfalfa
in the Antelope Valley in northern Los Angeles County is on the
wane. Considerable damage was done to the first crop, some farmers claiming that in a few cases the attack was so severe as to kill the plants. Ladybirds and syrphids are now very numerous and the aphis fungus is plentiful. It is expected that the infestation will be practically wiped out by these natural enemies, though this natural control will be, as is usually the case, too
late to save the first crop from damage.

ALFALFA WEEVIL (Phytonorras posticus Gyll.)

Idaho Claude 7takeland (April 30): At this date the alfalfa weevil is
just beginning to oviposit freely where, at the same time last season, worms had already grown to maturity. From indications
now injury from the w-eevil will occur at the end of the first
crop and on the second crop.

in all orchrirus oll-served.








109A. B. Burrell (May 18): They are very scarce at the present time
in Ontario County.

E. P. Felt '(May 25): Have been only moderately abundant, though
the extreme cold weather now prevailing is favorable to a considerable if not large increase.

Indiana F. N. Wallace (April 29): This species is already very abundant
on Spirea van bouttei around Indianapolis.

7{. F. Dietz (May 19): The green apple aphid has been very abundant on Spirea van Houttei but does not .seem to be particularly
abundant on apple.

APPLF---AIN APHID (hoapalosiphVum prunifoliae Fitch)

New York C. C. Wagoner (April 11): Very numerous on the opening buds in
Ulster County.

Wisconsin S. B. Fracker (May 12): Aphids average one or two to the blossom
in southeastern Wisconsin.

Minnesota A. G. Ruggles (May 13): At St. Paul the species of plant lice
on the apple which have been so abundant prove to be Phopalosiphnum
prunifoliae.

ROSY APPLE APHID (Anuraphis roseus Baker)

New York C. C. Wagoner (April 11); Nymphs are few in number at the present
time in Ulster County. The first ones were observed April 8.

G. E. R. Hervey (April 13): Rosy apple aphids have been observed
in practically all orchards but in small numbers in Dutchess County.

E. P. Felt (May 25): Have been only moderately abundant, though
the extreme cold weather now prevailing is favorable to a considerable if not large increase.

Pennsylvania H. E. Hodgkiss (April 29): The. rosy aphis appear to be of greater
State-wide abundance than at any time during the last five years.
Obsefvations made in 40 counties indicate that the infestation is
about equally severe over the entire State.

Maryland E. N. Cory (April 23): Mixed infestations of the rosy and green
aphids are present in many orchards in Washington County. Abundance is about as much as would be expected in a year of considerable damage to the crop.

Indiana H. F. Dietz (May 19): No heavy infestations of the various kinds
of plant lice attacking apple have been reported or seen up to the present time although the rosy apple aphid is present in moderate
numbers in some locations.









110

B. A. Porter (May 21): IDuring the past three weeks the rosy aphid has developed into a serious outbreak in many of the orchards in the southern part of the State. In some orchards
serious losses will be sustained. The first winged migrants
were noted on May 15.

Illinois W. P. Flint (May 22): No injury from this species has been reported or seen in the Illinois orchards this season. In a recent
examination of a number of orchards in the western and central parts of the State, only two twigs showed infestation by this species although a special lookout was kept for this aphid in
all orchards visited.

CODLINTG MOTE (Carpocapsa pomonella L.)

Illinois W. P. Flint (May 22): Emnergence of the codling moth from overwintering larvae has -been prolonged by the cold weather of the
first part of May. The maximum emergence of the insect is just
occurring in the central Illinois district. Emergence started
at about the usual period in the development of the fruit.

Missouri Otis Wade (May 8-11): Moths are very late in emerging in the
St. Louis region. Very little work showing up yet.

L. basemann (IMay 12): Moths emerging late, less than 50 per cent
of moths out on this date. Pupae, 66 per cent; adults, 29 per
cent, and larvae, 5 per cent.

Washington E. J. Newcomer (May 1): Owing to the early season, the codling
moth began emerging earlier than usual, the first mothst 1tg
noted at Yakima April 16.

AN APPLE LEAF EOLLER (Species undetermined)

Ohio H. A. Gossard (May 22): One of the apple leaf rollers, a species
undetermined, was observed to be quite numerous in an orchard at
Delaware May 19.

FRUIT TREE LEAF ROLLER (Cacoecia ar~yrospila Walk.)

New York C. 2. Crosby adC asshistate: lirst larvae of this insect-ar~
found in Uonroe Comuty on April 26, and in Orleans rand 7r
Counties about ivay 8.

Montana J. R. Parker (May 1): In the Bitter Root Valley leaf rollers
began hatching about April 20 and were complete about May 1.
About 84 per cent of eggs hatched, which is about normal. Apparently no damage to eggs by a severe freeze last November,
which killed many varieties of apple trees.










CIGAR CASE BEARER (Coleophora fletcherella Fern.) PISTOL CASE BEARER (Coleoohora malivorella Riley)

Yew York C. R. Crosby and assistants: Larvae of this insect were still
in hibernation ih Monroe and Wyoming Counties on April 11. Damage so far is but slight.

EYE-SPOTTED BUIMOTH (Spilonata ocellana D. & S.)

4ew York C. R. Crosby and assistants: The first part of May this insect
was generally abundant and doing considerable damage in Genesee,
and Onondags Oounties.byBy the middle of the month moths were
very numerous in Dutchess County.

E. P. Felt (May 25): Appears to be only moderately abundant in
the Hudson Valley.

Dhio G. A. Runner (May 16): The budmoth was observed to be abundant
and has caused considerable damage to young apple in the vicinity of Florence. Infestation was found to be general over-an orchard
of about 1,000 three-year-old trees.

LEAFP CRUMPLER (Mineola indigenella Zell.)

Missouri L. Hasenan (a y 12): In central M1issouri young orchard trees show
an unusual abundance of the overwintering cases and caterpillars
which are now approaching maturity. Attacking apple, haw, quince,
and plums.

FALL CAINKE'XWM (Alsophila nometaria Eart.)

New York E. P. Felt (May 25): Eggs were extremely abundant in one orchard
in Westchester County and the probabilities favor a somewhat serious
infestation in that general section.

TENT CATERPILLAR (1Malacosoma americana Fab.)

Connecticut W. E. Britton (May 22): Tent caterpillars have been unusually
abundant throughout the State on apple and wild cherry.

New York C. R. Crosby and assistants: Eggs hatched about the middle of
the month in Orange, Greene, and Dutchess Counties.

E. P. Felt (May 25): Moderately to extremely abundant in the
Hudson Valley and on Long Island. The caterpillars are nearly
full grown and are scattering in northern Columbia County.

H. C. Odell: Our tent caterpillar campaign in Suffolk County
has come to a close with a total collection of approximately
550,000 egg masses.

Maryland E. N. Cory (April 25): Nests of newly hatched larvae abundant
on wild cherry in Howard County.

Michigan R. H. Pettit (May 21): Mr. Gentner reports enormous numbers of
tent caterpillars in the vicinity of Cadillac and over quite a large area of which Cadillac is the center. He says that he
found as many as 12 on some trees, mostly on pin cherry and
other 'ild stuff, although they are working in the commercial
cherry orchards and apple orchards as well.

APPLE RED BUG (Keterocordylus malinus Reut.)

New York C. R. Crosby and assistants: By the middle of May apple red bug
was present in noticeable numbers in Orange and Dutchess Counties
and quite numerous in Onondag% County.

E. P. Felt (May 25): Appear to be only moderately abundant to
somewhat scarce in the Hudson Valley.

FALSE APPLE RED BUG (L d mendax Reut.)

New York E. P. Felt (May 25): Appear to be only moderately abundant to
somewhat scarce in the Hudson Valley.

TARNISHED PLANT BUG (Ljas pratensis L.)

Pennsylvania H. E. Hodgkiss (April 29): The tarnished plant bug adults are
numerous in the opening apple cluster buds where they appear to
be doing considerable damage.

Indiana J. J. Davis (May 25): Has been reported as abundant in several
orchards in the southern half of the State. Apples, apparently
injured by this insect, have been received. The injury resembles
that of the apple red bugs.








113
BUFFALO TREEHOPPER (Ceresa bubalus Fab.)

York. A. S. Mills (April 11): Punctures on apple limbs in Greene
County were found rather commonly in a few orchards.

lio 0.A. Runner (May 10): Numerous reports have been received of
injury to young apple trees. The buffalo treehopper is abundant
in'the commercial fruit growing districts along the South Shore of Lake Erie and seriously interferes with the growth of young
fruit trees in sod or along borders. Severe damage has been noted in orchards in alfalfa sod and trouble from this insect has prevented the practice of growing alfalfa in young apple
orchards from becoming more general.

PUTNAM'S SCALE (Asidiotus ancylus Putn.)

Termont C.R. Crosby (March 18): Infested bark received from Bennington.

SAN JOSE SCALE (AsPidiotus perniciosus Comst.)

ew York C. R. Crosby and assistants: By the middle of April reports were
received of light infestations in Onondaga, Ontario, and Erie
Counties.

|Ohio G. A. Runner (May 15): No increase in infestation over previous
years can be noted. "xaminations of peach orchards in Ottawa and
Erie Counties show an extremely light infestation and there seems
to be no evidence that the visual lime-sulphur sprays are not thoroughly effective. Some of the orchards under observation are in
a locality where one of the earliest outbreaks of the San Jose scale in the Eastern United States occurred. Counts of scales
from twigs of unsprayed apple made during the period April 20-11ay
10 indicate a high winter mortality. Six collections showed a
survival of 47.2 per cent.

Indiana B. A. Porter (May 21): First crawlers appeared May 20, which
is 7 to 10 days ahead of normal and 20 days ahead of last year.
This early start on the breeding season will probably enable the scale to overcome to a large extent the extreme winter mortality
Wftch has occurred.

Washington E. J. Newcomer (May 1): Counts of scale in the Yakiwa Valley
show a mortality of 35 to 65 per cent, due to the prolonged cold
weather of December 16-27, 1924, during tich time ttre temperature
was below zero seven nights and reached a minimum of 10 below.
In the spring of 1924 only 5 to 15 per cent of the scale was dead.

OYSTER-SHELL SCALE (Lepidosaphes ulmi L..)

New York P. J. Chapman (February 10): Infested twigs received from Oyster
Bay.
D. L. Hayes (April '11):' Prevalent in a few orchards at Genesee
in Wyoming County.

N PL BO











Indiana H. F. Dietz (April 28): The oyster-shell scale, the light brown
form of Glenn, was hatching in large numbers on April 22 to 26.
This is the earliest hatching since 1922, at which time hatching
began on April 24. In 1924 the first hatching date was May 16 and hatching continued intermittently until June 1. These records are on material that has been under observation sincei1921.

J. J. Davis (April 30): Eggs of the oyster-shell scale were not
hatching at Lafayette on April 29 although Mr. Dietz reports hatching at Indianapolis.

ROUNDHEADED APPLE TREE BORER (Saperda candida Fab.)

Virginia W. S. Abbott (May 18): A borer, apparently S. candida, has killed
or seriously injured a number of young apple trees in a small orchard near Vienna.

APPLE FLTEA WEEVIL (Orchestes pallicornis Say) New York D. D. 77ard (April 25): A very severe infestation was observed in
one or two plantings in Onondaga County.
Indiana B. A. Porter (May 21): Slightly more abundant than last year.
On May 7 i noted the first pupa and on May 16 nearly all the
larvae were mature and one-third of them had pupated.

FRTJIT-TREE LEAP SYNETA (Syneta albida Lec.) Washington E. J. Newcomer (May 1): This is the first time this insect, which
is a rather important pest in the coastal regions of Washington and
Oregon, has been noted in the Yakima Valley. It has previously
been reported, east of the Cascade Mountains, only at Walla Walla.

CLOVER MITE (Pryobia praetiosa Koch) New York D. D. Ward (April 11): The eggs of this pest are found very
commonly in orchards in south Onondag.

EUROPFAN RED MITE (Paratetranychus pilosus C. & F.) Connecticut Philip Garman (May 22): Dry weather in the section about New
Haven has favored development. More abundant than at this time
last year.

New York E. P. Felt (May 25): Eggs were somewhat numerous in some northern
Columbia Coiinty orchards in early spring. any mites hatched,
though there appears to have been a material decrease in the infestation during the last two reeks.

Ohio H. A. Gossard (May 22): The European red mite has been very conspicuous in orchards at Waterville, Hubbard, and Youngstown, and
in fact over nearly all of northern Ohio.







115shington E. J. Newcomer (May 1): This mite seems to be less common than
usual in the Yakima Valley. Winter eggs were noted this spring
as often as heretofore. Predacious enemies -of this mite were very numerous during the fall of 1924 and evidently interfered with the normal deposition of winter eggs, which watched April
10-17.

PEAR

PEAR THRIPS (Taeniothrips inconsequens Uzel)

ew York C. R. Crosby and assistants: From the 11th to the 18th of the
month this insect was emerging. The injury apparently has been
slight in Ulster, Greene, D utchess, and Columbia Counties.

PEAR PSYLLA (Psylla pyricola Foerst.)

ew York C. R. Crosby and assistants: Rdports received the middle of the
month indicate that this insect is very abundant and infestation
is heavy in general in Ulster, Orange, Monroe, Greene, Wyoming,
and Dutchess Counties.

PEAR-LEAF BLISTER MITE (Eriophyes Ry Pgst.)

Connecticut M. P. Zappe (May 22): Very severe on yougg pear trees, especially
Bartlett and Seckel at Bantam.

FALSE TARNISHED PLANT BUG (Lygus invitus Say)

New York A. B. Burrell (May 4): These insects were first observed on this
date in Ontario County.

SINUATE PEAR-TREE BORER (Agrilus sinuatus l01iv.),

New York C. C. Wagoner (April 11): This pest has extended its range a mile
or two this year in Ulster County.

PEACH

GREEN PEACH APHID (vzus persicae Sulz.)

Connecticut W. E. Britton (May 21): Fruit spurs and twigs around the center
of most trees at Eamden and Southington have curled leaves. Not many leaves curled on terminal twigs. Some orchardists are dusting with sulphur-nicotine; others are afraid of killing off the
natural enemies i7hich, in some orchards, bid fair to soon control
the aphids. Lady beetles are abundant and syrphid larvae are
present.

New York C. C. Wagpner (May 14): In Ulster County several heavy infestations have been found.








116L. E. Fitch (May 16): Several veryheavy infestations have been
noted in Nassau County.

Ohio H. A. Gossard (May 22): The green peach aphid was reported as
very damaging to peach blossoms at Clyde during the first week
in May.
E. W. Mendenhall (May 25): These insects do considerable damage
to the peach trees at Columbus. Destroy the leaves by curling.

BLACK PEACH APHID (Anuraoihis persicae-nier Smith)

North Carolina F. Sherman (May 13): Several reports have ben received; apparently a season of moderate, but not epidemic, abundance.

PEACH BORER (Aegeria exitiosa Say)

Georgia 0. I. Snapp (May 15): Complaints in regard to very heavy peach
borer infestations where paradichlorobenzene was not used last'
fall have reached the laboratory from growers in the Georgia Peach
Belt.

LESSER PEACH TREE BORER (Aegeria pictipes G. & R..)

Georgia 0. I. Snapp and assistants (May 1): Adults are now emerging at
Fort Valley. As usual the insect is common in neglected orchards.

PLUM CURCULIO (Conotrachelus nenuphar Hbst,)

Connecticut H. P. Zappe (Mlay 23): At 1t. Carmel either adults are very much
later than last year or are less plentiful, probably the latter as',"
the season is a little ahead of last year.

North Carolina F. Sherman (May 13): Dr. R. W. Leiby and J. A. Harris are working
with this insect among our commercial growers and report it as more
abundant than in previous seasons.

Georgia 0. I. Snapp (May 15): The very dry weather of the last two months
has materially retarded the activity of the curculio. On account of the low mortality during the mild winter and the increase in the
curculio population a year ago, as a result of a large quantity of
fruit left in the orchards, it was feared that much trouble would
be experienced this season in the Georgia Peach Belt from this
insect. However, the drought has curbed its activity by bringing
about mortality of the larvae when they fail to get the proper
nourishment in dry peach "drops" and- when unfavorable conditions
for pupation are presented.

Illinois W. P. Flint (May 22): The plum curculio, as indicated in an earlier report, is much more abundant than usual both on apple and
peach. S. C. Chandler reports sprayed peach orchards in southern
Illinois showing from 45 to 50 per cent injury by the curculio.
Apple orchards in west-central Illinois also show more egg punctures than in normal years.








117Missouri Otis Wade (May 8-11): Th the St. Louis region cherries and plums
were badly stung before the regular "shuck" spray could be applied.
tinfavorable weather has preveted effbdtive spraying. Unsprayed
fruits were damaged 75 per cent and sprayed fruits damaged slightly.
The abundance of curculios is above the average.

ORIENTAL FRUIT MOTH (Laspeyresia molesta Busck)

Connecticut Philip Garman (May 22): Emergence of the oriental peach moth began May 5 at New Haven and first eggs were obtained May 15. There
is no sign of the insect as yet in twigs in the field.

Maryland E. N. Cory (April 23): Eggs are present on foliage of quince at
Ringgold. Moths are flying in abundance.

Georgia 0. I. Snapp and assistants (May 15): There is a break in the
activity of the Oriental peach moth in the field at Fort Valley
at the present time, apparently between the first and second generations, as indicated by the sudden absence of larvae in
twigs in the field and observations in the insectary. A few
second-generation eggs and larvae have been taken in the insectary. First-generation moths are emerging.

RED SPIDERS (Tetranychus sp.)

Georgia 0. I. Snapp and assistants (May 15): At Fort Valley red spiders
are unusually abundant at the present time on peach foliage. It
is very dry; scarcely any rain has- fallen since March 15.

RED-LEGGED FLEA BEETLE (Crewidodera erythropus Melsh.)

Connecticut W. E. Britton (May 14): Adult beetles have defoliated a young
peach orchard at Danbury.

NEW YORK WEEVIL (Ithycerus noveboracensis Forst.)

New York A. D. Long (April 17): The insects were found doing injury to
a block of 3-year-old peaches in Orange County.

BROAD-WINGED TREE CRICKET (0ecanthus latipennis Riley)

Indiana J. J. avis (May 9): One row of a young peach orchard along a
weedy fence row at Mitchell was badly infested with tree cricket
eggs. Apparently it is 0ecanthus latirennis, which we have found common in the State the past winter, judging from the description
of egg punctures, etc., although we did not see specimens.

CBERRY

BLACK CHERRY APHID (Myus cerasi ab.)

New York C. C. Wagoner (April 11): These insects appear to be very numerous this year in Ulster County.












Indiana H.F. Dietz (April 30): A very heavy infestation of the cherry
plant-louse, Myzus cerasi hb,, was observed on several sour-C r
cherry trees in the. northern part of Indianapolis on April 28.

Wisconsin J. R. Arndt (May 4): Report of aphids on cherry at Marion.

SHOT-HOLE BOER (Scolytus ruralosus Patz.)

Indiana H. F. Dietz,(April 28): Following.the severe defoliation of
cherry trs n t localties in Indiana, due to the yellowleaf disease, Coccmyces 1Eieralis Higgins and C. lutescens Higgins, lat ynr a: the pass, rather drastic winter, considerable inj .y t these trees is expected this year. Already a number of-o orts of fruit-tree bark beetle injury to cherry
have been received by this office from the vicinity of Indianapolis.

PLUM

RUSTY PLUM APHID (Eysteroneura setariae Thos.)

New York 1. L. Hayes (May 2): An infestation of Aphis setariae has been
found in Genesee Comunty.
Georgia 0. I. Snapp.(May 15): This insect was very abundant in a commercial plum orchard several weeks ago at Fort Valley. An application of nicotine sulphate and the recent drought have com.pletely cleaned up the infestation.

Missouri Otis-Wade (May 9-'11): Very abundant on unsprayed trees and injuring foliage seriously in the St. Louis region.

EUROPEAN RED MITE (Paratetranychus pilosus C. & F.)

New York W. D. Mills (May 2): Infestation found on several prune plantings in Wayne County.

TARNISHED PLANT BUG (Lygus pratensis L.)

Nebraska M. H. Swenk (April): From Douglas County during the last week
in April came reports.s of serious injury to the buds of plum,
cherry, and apricot trees by the tarnished plant bug.

PULVINARIA SP.
Georgia 0. I. Snapp and assistants (May 8): The heaviest infestation
ever observed of this insect on plum was noted today at Fort
Valley.








7J19
RASPBERRY

RASPBESY F!JITVOIRM (Byturus unicolor Say)

Mbichign F. L. Simnanton (May 16): I wish to report a severe infestation
of the raspberry beetle in Berrien County. This beetle will destroy thousands of cases of red raspberries in this County
this year.

RED-NECKE CANE BORER (Aerilus ruficollis Fab.)

Missouri L. Baseman (May 12): This year's crop of black raspberries is
very severely damaged by last year's brood of borers. In some patches in central jissouri almost every cane is girdled by last
year's brood. Small host parasites are abundant in galls, usually
about four cocoons to each gall, species not determined.

BIACKBERRY

EUROPEAN FRUIT LECANIUM (Lecanium corni Bouche)

New York C. R. Crosby and P. J. Chalman (February 9-13): Infested. twigs
received from Clarksville.

GRAPE

GRAPE LEAFHOPPER (Er th~oneura comes Say)

New York F. Z. Hartzell (April 25): Appear to be very scarce at Fredonia.

Ohio G. A. Runner (May 5): Adults of the overwintering brood of the
three-banded grape leafhopper (Erythroneura tricincta Fitch, var.
cymbium McAtee) and other species injuring grape are not as abu-ndant in most northern Ohio vineyard districts as in the spring of 1924. This decrease seems due to the comparatively light second brood of last season rather than to weather conditions during the
winter. On the Lake Erie Islands where a heavy second brood
occurred last year adults of the overwintering brood of several species of grape:leafhoppers are numerous. (May 18); Damage
to young shoots of grape by overwintering adults of E. vulnerata
Fitch has been noted in a number of localities in Erie, Ottawa,
and Lorain Counties.

Missouri N. Turner (May): This insect is not present in the southwestern
part of the State where the greater acreage of grapes is set. All
indications show that the damage will probably be light this season.

California B.. A. Harrigan. (April 20): This insect is reported as doing considerable damage this year. It is practically impossible to cite
specific" localities where injury has occurred as it has been so
general and extensive.

A. 0. Larson (April 29): In Stanislaus and Merced Counties the first brood are injuring all the lower foliage and appear to be
doing much damage.

GAPE PLEA BEETLE (Haltica chalybea Ill.)

Connecticut B. H. Walden (May 22): Buds have been destroyed at South Glastonbury. New buds have formed on the vines. The crop has been
damaged 40 to 50 per cent. Beetles apparently have left the
vines.

Pennsylvania H. E. Hodgkiss (April 29): The grapevine flea beetle or steely
beetle is causing quite a lot of damage in several of the southern counties.

Maryland E. N. Cory (April 27): No eggs yet at the College.

M. D. Moore (April 28): Report of flea-beetles attacking grapes
at Hagerstown.

Missouri L. Haseman (May 14): During the past month this pest has been
doing considerable damage in places, although where early applicaitions of sprays were made they controlled the pest.

Nebraska M. H. Swedk (April): The grapevine flea beetle was first noted
on the grapes April 12, and 10 days later was being seriously
complained of in several localities as injuring the grape buds.
This appearance is nearly two weeks earlier than last year.

CLIMBTIG CUTWOIRMS (Lampra spp.)

New York C. R. Crosby (May 10): Considerable injury noted at Crosby by
climbing cutworms.

Ohio G. A. Runner (May 15): Climbing cutworms have caused considerable damage to buds of grape in a number of localities. Injury
has not, however, been as severe as in 1924. Several species
have been observed to feed on the unopened buds, the more abundant species in the Sandusky vineyard section being Igmra cupida
Grote.

APPLE TWIG BORER (Amphicerus bicaudatus Say)

Nebraska 1. H. Swenk (April): Several reports were received during April
of injury to grape canes by the grape cane borer, Schistccerus
hamatus.

GRAPEVINE HOPLIA (Hoplia callipyge Lec.)

California A. 0. Larson (April 29): The grapevine hoplia, determined as
Hpolia callipyg LeConte, appears in limited numbers annually in
some sections, especially near Atwater, but growers in that section
say that the insects are much more numerous than usual and that









they are infesting areas formerly uninfested. Ordinarily the
shoots are only 3 inches long -when the attack begins but this
year the grapes are further advanced. The shoots are 12 to 15
inches long, consequently there is much more foliage.

CURRANT

APHIDIDAE

Minnesota A.G. RKThies (May~13): Other plant lice noticed working at the
present time at the University Farm are the currant aphid, yzus
ribis and the snowball aphid, A-phi communis (?).

CURRANT APHID (,lz's ribis L.)

Virginia W1. S. Abbott tMay 18): This aphid was noted for the first time
about May 2 at Vienna.

IIPORTED CURRAiNT0~OM (Pteronidea ribesi Scop.)

New York C. C. wagoner (May 11): This insect was found hatching on
May 11 in Ulster County and growers are generally applying
spray for its control.

Indiana H. F. Dietz (April 28): The eggs of this insect began hatching on April 27. The fruit on the currants at this time is about the size of small peas, and this date is 10 days after
the blooming period of the currants.

Minnesota A. G. Ruggles (May 13): The currant sawfly is at work at the
present time laying eggs.

SAN JOSE SCALE (Aspidiotus perniciosus Comst.)

New York 0. C. Wagoner (April 11): A much lighter infestation is in
evidence in Ulster County than in former years.

BLUEBERRY

BLACK-LINED CUTWOPM (Aprotis fennica Tausch.)

Maine E. 1I. Patch (May 12): These caterpillars have taken the blueberry crop over an area which at present estimation extends
about 20 miles and every hour the scouts bring in new reports of damage. One man yesterday indicated his loss alone as
$12,000 and from the rate the larvae are working he seems sure
to lose another $12,000.
I have distributed the standard recommendations concerning cutworms arsenical sprays, dusts, and poisoned bait. I have
used also the Bareau of Entomology circular together with a
garden cutworm circular of our own in order to get across the
life history, especially the fact that the performance must
have started late last summer or in early fall.






122

My especial need just now is to know the formula for sprays, dusts, or cutworm poisoned bait which is at present being recommended, if there is any change over those in the circular.
One man intended yesterday to divide his area and test all three
remedies. For this particular attack the poisoned bait would
seem the best chance; but there is considerable fear of this on
the part of some of the blueberry growers from the bird standpoint. In certain localities the crows are feeding in good
shape on the cutworms.
The particularly pernicious feature of the attack is that the cutworms are taking only the blossom buds (not yet open).
The surrounding colored bracts of the bud cluster are not touched. Th7e young leaves have so far escaped for the most part.
Of course, this type of feeding means that the larvae are concentrating on what will ruin the crop quickest.
Ther3 is'something queer, too, about this daintiness of appetite. I can not think that the infestation could have accumulated to its present status on such a basis. I assume
that the early-instar larvae last season were feeding on something other than blueberry. If I am right in calling this
caterpillar Agrotis fennica, I assume that same member of the
family Legminosae would be the logical attraction for the
moths at egg laying and for the young caterpillars. I can
not at present think of any such plant in the blueberry barrens
except "hop clover."
The caterpillars in the field are Ribbling at Maianthemum
canadense and wild raspberry but neither seen to rank as a real
attraction.
As the larvae remain hidden during the day and as the injury to the blueberry is to be seen only on close examination, this
was reported to us only a few days ago.
The larvae are exhibiting the army habit; but the usual methods applied against the real armyrorm in grain fields can not be used
here. A furrow can not be plowed in the barrens and the extent or direction of the movement can not be detected from the appearance of the vegetation except at close range.

PECAN

EUROPE A 7ALNUTJ APHID (Chromaphis juMandicola Kalt.)

California W. C. Barber (May 5): Serious damage to walnuts at Bakersfield.

A WHITE GRUB (Phyllophag micans Knoch) Alabama J. M. Robinson (April 29): Just at present Phllopha. micans
Knoch is working on pecan foliage in the Mobile district. H. P.
Loding of Mobile has just informed me that Dr. Van Allen of Baldwin County has sent in several specimens of Metachroma pallidum
Say defoliating pecans and persimmons and doing considerable
damage. The dead and dying Satsuma trees are being attacked by the Elaphidion inerme. The adults were emerging from the
trees April 25.

MI LLIPEDES

Ohio H. A. Gossard (May 22): We received from Mingo Junction, a
millipede, apparently belonging in the g:ous J,~ais, which
was reported to be exceedingly damaging to potatoes and
garden crops. That appears to be this same millipede came to
us several times last season and the seasonTbefore with the report that it was making the production of Irish potatoes
impossible. Many farmers in northeastern Ohio the past two or three years have been compelled to cease the growing of Itish
potatoes on account of this pest. Its injuries and distribution
seem to be very much on the increase. It appears to have the
ultimate possibility of being ranked as a major garden pest
equal to or surpassing the white grub in destructive qualities.

A FALSE WIREWORM (Eleodes omissa borealis Blaisd.)

California White C. Barber (May 2): This insect is moving from the desert

Mexico A. W. Morrill (May 11): This insect is one of the leading insect
pests of tomatoes in Sinaloa and Nayanit,fImtuating in abundance
in different districts from year to year. Three and four years
ago it did no noticeable damage in the Fuerte Valley, which is
the principal tomato-growing district on the Mexican West Coast.
In the season of 1922-23 an outbreak occurred, covering less than 100 acres of a total of 5,000 or 6,000 acres of tomatoes growing
in this district. During the season of 1923-24 the insect did
heavy damage to about 1,C000 acres of tomatoes. During the present

exico A. W. Morrill (May 11): This insect was unusually abundant in the
vegetable growing sections of the west coast of Mexico (States of
Sonora and Sinaloa) during the months of February, March, and
April. One close observer, superintendent of a ranch, reported about 1 per cent infestation in the peas brought to the packing
shed. The harvesting season was oved so it was too late to verify the percentage, but specimens were found in the old fields sufficient for identification. About one hundred miles south in the
Sinaloa River Valley the manager of a r4nch where several hundred acres of peas were grown for spring shipments repo-ted an average
of approximately 15 per cent damage by the bollworm. An examination of 114 pods selected at random froM the bins in the packing
shed showed 55 or approximately 50 per cent damaged with a total
of three live specimens present inside the pods, This is the first time in my four years contact with West Coast vegetable
growing conditions that an attack Of this kind to peas has-been
reported or observed. In the Fuerte Valley at about the same
latitude as the point where the above mentioneA observations were
made in the Sinaloa Valley there has been an unusuAl amount of
damage to tomatoes from the bollworm. This damage had reached as
high as 20 per cent in some fields, and wva increasing when my
last observations were mad-e about the 20th of April. In the
Culiacan Valley, less than 100 miles farther south early in
April it was observed that 'bollworm damage was much more extensive than observed during the last four yeats. A rough estimate in one
field of 300 acres placed the datnage at not less than 25 per cent.

The percentage of weevils placed in cages last fall which had
emerged prior to 14.iy I at the different points is shown in the
following table:
Pair. -cent of number put into Locality cages which have emerged

Auburn, Alabama - - -------11.54

Experiment, Georgia - 1.33
Aberdeen, North Carolina --- ---- --.84 Rocky Mount, North 0arolina ------- 32 Holly Springs, Mississippi - -- .0 Tallulah, Louisian - -- - - .01

The most interesting figure so far this spring is the exceedin ly high emmrgence of 11.54 per cent at Auburn, Ala.
Appeoximately the same number of weevils were placed in the same
cage during the fall of 1923 and up to this date in 1924 no
weevils had emerged.
At Florence, S. C., the emergence in 1924 prior to May 1 was
0.15 per cent: This year, however, the emergence prior to May 1
was 4.66 per cent.
The survival at College Station, Tex., continues to approach
a normal one.
At Tallulah, La., in the average of nine years, about 140 per
cent of the total emergence has been completed by May 1. The
average emergence prior to May 1 in the last nine years is about
O. 6o ir cent. This yeaor, however, the emergence is only 0. 01 per
cent.
It is interesting to note thattthe weevil emergence is still progressing, further indicating that the weevils have been able
to survive the winter in fair numbers at most stations.

Co-operative Report on Boll Weevil Emergence from Cnge Tests Prir

emerged prior to May 16 at the different points is shown in the
following table:

At Tallulah, La., in the average of the ast nine years, about 65 ier cent of the total emergence Yas been completed prior to
May 16. The average emergence prior to this date has been about
0.99 per cent. This year the emergence to the same date was
only 0.01 per cent.
At Florence, S. C., 56 per cent of the total emergence was completed prior to May 16 in 1924, The emergene was 0.19 per cent.
This year the emergence prior to the same date was 5.15 per cent.
At points near College Station, Tex., in 1906, 1907, andl9Ogs,
the average total Turvival was 5.2 per cent. About 92 per cent of the total emergence was completed in these years prior to My 16.
The average emergence on the same-date was about 4.5 per cent.
This year on the same date the emergence was 5.49 per cent.
At Auburn, Ala., in 1924 no weevils had emerged under the same
zqge condition prior to May 16, while this year 13.49 per cent
had emerged. ..
It is interesting to compare the weevil emergence during the
last three fifteen-day periods. At all points, with the exception
of Auburn, Ala., a total of 293 weevils emerged from April 1
to 15, a total of 639 weevils from April 16 to 30, and a total
of 210 from May 1 to 15.
At Brownsville, Tex., on May 14, Mr. T. 0. Barber examined 142
fallen cotton squares for weevil stages. In this number 61
larvae, 9 pupae, and 1 adult that had emerged were found, making
a totalI of 71 living weevil stages. The most interesting point
is the fact that adults weevils of the first brood have just
started to emerge. These squares were collated in a field that
was estimated to have 362 hibernated weevils per acre on April
15. The weevilU infestation in that vicinity is extremely spotted, in some places being very heavy and in others very
light.

North Carolina Franklin Sherman (May 13):- We. have five field cages under
oble>'vtion, stocked with 3,249 weevils. However, I think our truest inference may be drawn from two particular cages which
appear to approach closest to natural conditions of hibernation.





At the end bf April, in one of these cages (in the southern portion of the State) 1.40 per cent of the.weevils had emerged: in the other
cage -(northeastern portion of the State)*1.06 per cent had emerged.
Combined they show. a n emergence of 12, out of 949 weevils, or 1.26
per cent at the end 6of April, .and this I believe, to be our truest
S .indication of what has hapened North Carolina. Messrs. Lieby
and Harris in work with'peech insects at Aberdeen, N. U., jarred the
boll weevil from peach trees in mid-April.

Alabama J. M. .Robinson (April 29): Bo11 weevils have been very'active the
last week in emerging from hibernation cages in rather large numbers.
As _&ny as 116 emerged in one day.

COTTON LEAFTVORM (Alabama araillacea Hbn.)

cfined to grehue' osraoies; and it is of considerable economic importance there, as heretofore.








COTON'Y CUSHION SCALE: (Icerya purchasi Mask.)

Louisiana H. K. Plank (May 12): .The increase of this pest at N1ew Orleans
during the past fall and winter was sufficient to cause general
41rm, and fear was entertained by some that the infestation
would approach the seriousness of that of 1915-1917, rthen numer*ous other plants than Pittosmorum tobira, Plumbago sp., Ulmus
sp., Picus pumila, and Manol ia grandiflora were heavily
infested and considerably injured before Novius cardinalis could be satisfactory. colonized. However, since the finding of larvae
of the Novius at work on numerous infestations throughout the
city on February 3, 1925, and subsequently, the abundance of the
cottony cushion scale has been so reduced that it is now very
difficult to find any live adults anywhere in the city. The injury
to the hosts mentioned has therefore been comparatively slight.

DICTYOSPERM.M SCALE (Chrysomphalus dictyospermi Morg.)

Louisiana H. K. Plank and assistants (May 13): Since the freeze of January,
1924, this scale has been increasing only very gradually and very

out-of-d6ors, except on a few cycads and climbing figs in one or
perhaps two places in the city. Attacking _cas revoluta, Ficus
pumila, and Cinnamomum camphora.

SURINIAM ROACH (ycnoscelas surinamensis L.)

ennsylvania C. A. Weigel (May 14): Under.date of April 2,,ve received
specimens of the Surinam roach, ycnoscelus surinamensis, from
the vicinity of Philadelphia. In the letter '7hich accompanied
these specimens the statement was made that they were seriously
injuring roses grown in greenhouses. This species has previously
been reported as injurious to roses, lilies, poinsettias, and
other plants grown under glass.
Mr. Doucette in a letter dated MIay 10 makes the following
report: A very heavy infestation of the Surinam roach has been
discovered through H. F. Dietz and T. L. Guyton in one of the large commercial rose houses in this vicinity. An examination
of this infestation revealed that they were-feeding on rose
and that the infestation is so heavy that the stems of probably 30,000 or more plants have been girdled for about 2 to h inches
above the ground, which will make it impossible for the plants to "come back' after they have been rested and "cut back." 7We
have seen only 3 or 4 cases of feeding on any other parts of the plants. The owners have already used over 15C gallons of
kerosene in trying to control these roaches. This has been applied on the walks and on the edges of the rose beds. The
infestation is still very heavy although very large numbers have
been killed by the oil. We are now conducting experiments with various insecticides and chemicals that have been reported as
effective against this species.

iebraska1 M. H. Senk (April): More than the usual number of iiqtuiries on
the control of ants in lawns are being received, indicating a
supernormal amount of injury of that sort.

HOUSE FLY (M.asca domestica L.)

Ohio F. C. Bishopp (April): Ot April 5 a few house flies were
present, some entering office buildings and residences., (April 17)*
House flies have increased considerably in number and are now causing some annoyance in residences. (April 2).:. No material
increase in number of house flies apparent since April 17.

TEIITES

North Carolina F. Sherman (May 13): Reticulitermes flavipes reported as
destructive to fire hose,possibly a new "food plant."

Chio H. A. Gossard (May 22): Termites were reported attacking a dwelling
house at Harpster, April 3. Each year we get a greater number of
reports of damage of this kind than in the preceding year.
Furnace-heated houses and basements are making life possible for
these tropical insects and all old construction houses with timbers in- contact with the earth seem ultimately doomed to
destruction unless concrete foundations are put in.

Indiana J. J. Davis (May 25): Injury to woodwork in a house reported on
May 2 from Monticello.

Illinois W. P. Flint (May 2): A number of reports oE damage by'Reticulitermes flavioes Kol, have been received during the last two
months. Several of these have been investigated and in at least
two cases the damage rill amount to several thousand dollars,
One of these, a modern brick schoolhouse with wooden floor
timbers and wooden sheathing on the stairs and doorways, has been
damaged to such an extent that the interior will have to be refinished throughout.

Kansas J. W. McColloch (May 21): Termite injury to dwellings has been
reported from Parsons and Great Bend. At Manhatten termites ruined the woodwork in one of the largest business houses. A sample of flour ias received from Clay Center which had been infested by termites. Undoubtedly the sack of flour had bhen
resting on a wood floor.

Nebraska M. H. Swenk (April): Another report of injury to a house by the
termite Reticulitermes tibialis Banks was received during April from Fairfield in Clay County. (May 18): A house in Hall County
was reported as damaged by this insect on this date.

A AMN ANT (vMyrmica brevinodis Emery)

Montana R. A. Cooley (May 4): Troublesome on lawns and entering houses
at Bozeman- widely distributed in Montana, reported this year and
every year.









A IrfiIAPOD (Scutiaerella immaculata Nevip.)

chio ncA. Gossard (May 22): The symphylid Scutigerlla immaculata
Newport was doing considerable damage to greenhouse crops in
Cincinnati in April. Some growers think damage is reduced by
using plenty of well-rotted barnyard manure. This decaying organic
matter supplies the natural food of the insect so it is not
obliged to attack growing crops, according to the theory of these
growers.

CLOVER MITE (3ryobia praetiosa roch)

Wisconsin S. B, Fracker (May 1): Two reports of invasion of houses by mites
coming from clover in lawns at Milwaukee and Waupaca.

SOUTERN COWPEA 'EEVIL (Mylabis ou;imaculatus Fab.)

California Monthly Letter of the Bureau of Entomology No. 132 (April): In
April C, K. Fisher examined, at Ehino, Calif., a stock of bean
straw which had stood out in the open two winters and one summer.
Man, black-eyed cowpeas were found infested with Myvlabris
nuarimaculatus Fab. Enough weevils were found breeding.in the
seeds which had escaped the threshing operation to furnish a
source of infestation for the coming growing season. Last fall an
investigation of infestations in the Chino region showed that this
same stock of bean straw was responsible for infestation in 1924
of beans growing as far as one and one-foUrth miles away. Mr.
Fisher also found Mylabris obtectus Say breeding in another
,stock of red kidney bean straw two years old.

BANJ WEEVIL (Mylabris obtectus Say)

Wisconsin S. B. Fracker (March 1): The unusual number of complaints dere

INTE RCPTIOTS

April, 1925

The following important interception was recently reported by the inspector at Philadelphia. A bundle of broomcorn, manifested as whisk brooms, was found in cargo discharged from the SS. Ossa from Italy. Specimens of the European corn borer (Prausta nubilalis Ilbn.) were collected'from the shipment which.was abandoned by the consignee end destroyed.

on February 14,1925, a collaborator of the Federal Horticultural Board found a sack containing several hundred citrus leaves in the suitcase of a passenger arriving at,.Key West from Cuba, The passenger was going to Tampa, Florida, The leaves were infested ,with citrus blackfly. This interception presents a striking example of the necessity of close supervision of baggage inspection.

Since the last issue of the letter of Information, determinations have been received for interceptions of larvae, papae, and adult oof Mediterranean fruit fly (eratitis capitataa Vied.) as follows: In commercial shipments of oranges from Spain, taken at New York, January 19th, 23d, and 26th; in cormnercial shipments of sour oranges from Sicily at N Yor:, January 30th, February 11th and 17th; in bitter oranges from Italy at New York, February 11th, in tangerines, Mndarin var., arriving at New York as cargo from Messina, Italy, Canary 19th; in green olives from passenger's baggage from Italy at New York, December 6th,1924, and in qpince from passenger's baggage from Syria at Providlnce, Z. 1. November 13.1924.

The }arvae of the 'West Indian fruit fly (Anastrepha fraterculus Wied.) vere taken by a New York inspector from guavas from Porto Rico, December 24, 1924, The guavzs were brought in as baggage.

An unidentified species of Anastreha was found at New York February 5,19 5, infesting mangos from Peru. The magos were in ships stores.

A very important interception is credited to the Boardts collabotator at Jacksonville, Florida, who found in the post office at JackCsonville and diverted to Washington, D.,C.,about February 1st, a package from Cuba containing cotton bolls. The bools were infested with living larvae of the pink bollworm.

Philopedon plagiatus Schallen, European weevil of the family Otiorhynchidae, which is -ot known to occur in this county, was taken from vegetable seed arrivingg by mail at the Inspection HousO











ix Washington, D. C.,from Holland, January 30,1925, The specialist who identified the weevil states that it is an injurious species.

A mealybug (Pseudococcus maritimus Ehr.) on apple from the Azones was collected at Providence, R. I., by inspectors from Boston, October 22,1924. The specialist who made the identification stated: I believe a new distribution record."

An identification has recently been received of a potentially dangerous potato weevil (picadrus cognpatus ) specimens dfwhich were collected at Galveston, Texas, October 17,1924, in potatoes from Vera Cruz, Mexico. The potatoes were in ship's stores. So far as is known this insect does not occur in the United States.

Inspectors at Key West, in the ordinary course of routine inspection work, March 29,1925, discovered in the ship's stores of a Standard Oil Tanker from Tampico, M14xico, a quantity of grapefruit and oranges. Inspection of this material showed no external evidence of infestation of any kind, that is,mof fruit fly. A number of the fruits were cut and in three of the grapefuit a large number of larvae were discovered. None were found in the oranges which were dissected. Specimens were forwarded to Washington and identified by the specialists as larvae of Anastrerha ludens Loew. The above interception strikingly emrihsizes the 6:anger of introducing pests in stores of oil taskmDs and clearly shows that the iinspection of such vessels is very necessary.
