Vol.7 August 1, 1927 No. 6

OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR JULY, 1927

Scouting for the European corn borer has been in progress for only
three days, as the seasonal development is late. Scouting up to this date
has been limited to confirmation of the presence of the borers in the coun-
ties on the border of the quarantine area and the crews are reporting them
in these counties in numbers at least as great as those found in 1926.

Throughout the eastern part of the United States one of the most con-
spicuous features of the month was an unusual abundance of aphids on a great
variety of crops and ornamental plants. Shade trees inmany places were al-
most black with sooty mold.

The alfalfa weevil has advanced&from about 40 miles west of the Nebraska-
Wyoming line to about 8 miles west of that line.

The Hessian fly seems to be about normally prevalent throughout the
wheat belt with the exception of the Kansas area, where it is estimated that
20,000,000 bushels of wheat were destroyed by this insect.

Allowing for the alarm caused by the European corn borer, the common
stalk borer appears to be unusually prevalent throughout the Middle Atlantic,
East-Central, and West-Central States.

The black cutworm continued throughout the month to be a serious pest
in the recently flooded areas of E: ssissippi and several points.in Indiana
and Nebraska.

Scouting for the Japanese beetle outside the area now under quarantine
has been in -operation about one week, It is too early to tell whether there
will be extensive spread of the general infestation but a strong movement to
the south is indicated.

In the Ohio River Valley the codling moth was somewhat later than
usual in emerging. This, coupled with the destruction-of the fruit by frost,
has very materially reduced the population of this insect.

An interesting note has been received from 1aine reporting destruction
of fruit buds by elaterit adults. This type of attack has been recorded for
several.years from the Pacific Northwest.

In Georgia the oriental fruit moth has spread from the few orchards
where it was recorded in 1926 to the entire Fort Valley district.

The plum curculio has been unusually prevalent and destructive over the
entire Atlantic seaboard.

Owing to unusual weather, conditions the cherry maggot was so greatly
delayed as $to render..it.~gf nq importaice to the cherry crop in Michigan.
been
'Mealybug, infestati0on have/materall-y heavier than during last year in
the southern California citrus belt. During the month of May of this year,
the Los Angeles County insectary liberated 1,612,.00 Cryptolaemus beetles,
and during April another 500,0CO were liberated, to. control this pest.

One of. the interesting features of the season has.bb;een the finding of
the Mexican fruit 7orm in Texas early in June.. Specimens were collected at
Mission, Hidalgo County and twa points in Cameron County.

The Mexican bean beetle has very materially increased its area of in-
festation. .It has advanced eastward to WMshington and Frederick Counties in
Karyland; in Virginia, to Norfolk and the Government Experimental Farm at
Arlington near Washington, D. C.; in North Carolina, it has spread northeast-
nard to "Wake and Robeson Counties; northward in Indiana to, Indianapolis and
Richmond and westward to O&en and Dubois Counties'; in Pennsylvania, to Erie
County; and in Michigan, to lonroe'County.

The seed corn maggot has been quite prevalent in parts of New York,
lichigan, and Iowa.

Though unusually late in appearing in.the pepper fields of California
the pepper weevil is now iell spread over the pepper-growing section and the
present indications arc that the loss will be heavy this year.

The boll weevil survived the winter in better condition than last year
*in North Carolina, South Carolina, and-4ississippi, while the records indicate
that survival w as lower than last year in parts of Georgia, Alabama, and
Louisiana. Later reports indicate that this insect is generally more destruc-
tive than last year in North Carolina, central Georgia, Alabama, and Kiss-
issippi. Little boll--eevil damage is reported from South Carolina, Louisiana,
and Texas.

The cotton flea hopper situation is decidedly better than last year,
practically no damage being reported from any.part of the cotton belt.

The cotton leaf worm has stripped the cotton as far northward as San
Marcas and eastward to Houston in Texas. In general this insect has not been
reported over the eastern part of the cotton belt as yet. A single specimen
of the leaf worm has been reported from Tennessee.

The tussock moth is generally more prevalent than usual over the Mid-
dle Atlantic and East Central States extending vwestward to eastern Iova and
Nebraska.

OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA, FOR JULY, 1927

Grasshoppers of several species are very heavily infesting open grass
ranges in south-central British Columbia from Ashcroft to Quesncl. Cattle
country comprising some 2,000 square miles is badly infested and there is dan-
ger of the range grasses being seriously reduced.

The clover root borer is gradually exterminating red and alsike clovers
throughout the north end of the OkanaganValley, and adjoining areas, in
British Columbia.

A light infestation of the potato stem borer is reported thrcughout
the southeastern counties of New Brusswick, affecting a variety of field and
garden plants.

Reports of severe wireworm injury have been received from points in
southern Quebec, southern Manitoba, western Saskatchewan, and Vancouver Island.

Observations at points in southern duebec and along the St. Lawrence
River show the onion-maggot infestation to be, in general, more severe than last
rost,from# 40 to 80 per cent of plants being infested.

The spruce budworm is heavily infesting balsam, fir, and spruce over an
area of several hundred square miles north of Thor Lake, Ont. This outbreak
has been in progress since 1922, with the result that the fir is largely dying
or dead and the spruce growth seriously retarded.

Eighty-eight per cent of cocoons of the larch sawfly examined in the
Spruce Woods Reserve, Manitoba, were found to be parasitised tith the intro-
duced parasite, Mesolieus tenthredinus Morl. Adults of this parasite are be-
ing liberated at points in Eastern Canada.

On the mainland east of Moose Island, in the vicinity of Lake Winnipeg,
Manitoba, the spruce budworm has entirely killed out mature balsam and has
weakened white spruce. A large percentage of the latter is being killed by
the bark beetle IpS perturbatus Eich.

The white pine weevil is infesting the terminal shoots of young jack
pine trees on the Sandilands Fr est Reserve, Manitoba.

There is a general and heavy infestation of the box elder plant louse
on Manitoba maples in Saskatchewan.

The satin moth was responsible for complete defoliation of infested
poplar trees in the Victoria district. B. C., this summer.


A1th the completion of bark-beetle control work in' the Aspen Grove dis-
trict, the last of the bark-beetle outbreaks in yellow pine in British Columbia
has been brought under control, with a consequent saving of millions of dollars
worth of valuable timber.











In the Niagara peninsula, Ontario, the pear psylla heavily infested
unsprayed orchards and orchards that -:ere sprayed too late.

The saskatoon sawfly, Ho2locampa halcyon ort., is abundant and wide-
spread in southern ianitoba, there it destroyed 75 per cent of saskatoon beries.

Aphids of many species have been reported unusually abundant in restern
Nova Scotia, the Niagara peninsula, Ontario, and contral Saskatchenan. Seri-
ous infestations of the green apple aphid on young apple trees are reported in
the Okanzagan Valley, British Columbia.

Rose leafhoppers were very abundant on roses in June and apples in
July, in the Vernon district, British Columbia.

Severe outbreaks of the apple leaf sever, Albononyra vicarialis Zell.,
have occurred in apple orchards of the Annapolis valley, Nova Scotia, where
the insect is more numerous than ever previously recorced.

GRASSHOPPERS (Acrididae)

Ohio T. H. Parks (July 25): We anticipate no damage by grasshoppers
this year.

South H. C. Severin (July 18): There are no grasshoppers to speak
Dakota of this year

Nebraska M. H. Swenk (June 25 July 25): A few reports only of injury
by grasshoppers are being received. There has been a moderate
hatch of these insects in the North Platte Valley, with some
threat of serious injury, and during the third week in July a
few reports of an abundance of grasshoppers in alfalfa fields
were received from scattered localities along the eastern
edge of the State,

WHITE GRUBS (Phyllophaa sp.)

Iowa C. J. Drake (July 12): White-grub injury, brood "A," is begin-
ning to show up in the entire eastern half of the State with
a few localities in the western half.

Nebraska M. H. Swenk (June 25 July 25): Since the middle of June,
scattering complaints of damage by white grubs to strawberry
beds and rose and flower gardens have been received,


Ohio T. H. Parks (July 25): Aphids have had their inning this year.
Almost every crop suffered more than usual. Spiraea led in
the shrub line. Potatoes and tomatoes were damaged in local-
ities by Illinoia solanifolii. Green apple aphid appeared in
many orchards and damaged young trees. A field of sugar beets
in Lucas County was found to be almost destroyed by aphids Ju-
ly 22. We have had the most severe visitation in years. Aph-
ids on maple trees are now about one, being controlled by par-
asites and predators.

Illinois C. C. Compton (July 9): Many species of plant lice are unusu-
ally abundant at this time. Cabbage is suffering most.

Alabama J. M. Robinson (June 30): Plant lice are showing up in spots
in central and southern Alabama. However, the par"sites and
predacious forms are apparently keeping them considerably re-
duced

A WIREWORD (Melanotus spp. )

Minnesota A. A. Mail (July S): On a recent rrip throughout the south-
western sections of the State, I found two wireworms which
appeared to be doing the heaviest damage and these I am go-
ing to concentrate on as the major wireworm pest in Minne-









r
sota. The most abundant is the dark brown, very cylindrical
larva which I think is Melanotus. In an infested field I
obtained a few beetles which I take to be the adults of the
larvae. (Specimens determined by J. A. Hyslop as Melanotus
sp.)


C ER-EAL AND F O RA G E C. CROP INSECTS

MISCELLANEOUS FEEDERS .

GREEN BUG (Toxoptera graminum Rond.)

Minnesota A. G. Ruggles (July 15): Toxoptera graminum was found thinly
distributed over a wide area in southern Minnesota late in
June, the first ones found being isolated migrants. In a few
places,'on very late .grain, there has been considerable increase
and slight injury seems likely. In most fields the grain is
well' headed and -little increase of Toxoptera has occurred.

PEA APHID (Illinoia pisi Kalt.)

Wisconsin J. E. Dudley (June.25): The general distribution and establish-
ment of aphids in pea fields, also alfalfa and clover, would
seem tojustify the prediction that they will be more than usu-
ally abundant in July, especially if the weather turns hot. It
is possible, however, that the aphid's enemies, particularly
syrphids, may be able to keep the infestation below normal.

ARMYWORM (Cirphis unipuncta Baw.)

Missouri L. Haseman (June 28): During the month two complaints were re-
ceived with samples of specimens of the regular armyworm though
no epidemic has developed

Nebraska M. H. Swenk (June 25 July 25): Reports of commercial damage by
the armyworm were not-so numerous as the cool weather seemed to
indicate they would be, but the larvae were quite commonly and
generally distributed in grass' and grain fields over the south-
eastern part of the State.

WHEAT



~ISSIAN FLY (Phytophaga destructor Say)
Ohio E. ". ilendenhall (July 6) Clark County has about 13 per cent of
Hessian fly infestation' according to the recent wheat-field survey.
(July 8): Champain has about 8 per cent Hessian fly infestation
according to the recent. -rheat field survey. A reduction over last
year. So much for better cooperation in the proper time of seeding.
(July 14): Logan County has 15i per cent Hessian fly infestation.
By inspection they are found now in'the "flaxseed" state or resting
stage. Wheat was sown rather late but there was a lot of volunteer
wheat which may be the cause.









197 -
T. H. Parks (July 25): The annual wheat survey has been com-
pleted in Ohio. Thirty-four counties were inspected and the
percentage of Hessian fly infestation determined in each. The
situationis satisfactory in the southern one-third of the
State or south of a line drawn through Zanesville, Columbus,
and Springfield. It increases in the north central belt, and
the northern half of the State has had a rapid increase in in-
festation. Four counties in northwestern and one county in
northeastern Ohio now have between 40 and 50 per cent infesta-
tion of the straws. The average infestation fot the State is
20.5 per cent compared with 9 per cent in 1926. The present
crop did not suffer much owing to good growing weather and the
most of the infested straws remained upright. The rapid in-
crease in the infestation was due. to the presence of volunteer
wheat which received the eggs of the fall brood last year and
which was kept growing in the old stubble fields by abundant
fall rains. We shall make an effort to hold off seeding this
fall and with normal fall weather, expect to win out.

Michigan R. HE Pettit (July 18): The Hessian fly appears to be coming
back with us here and there. We have no facilities for mak-
ing a survey over the State, but we find it in moderate numbers
wherever we look.

Nebraska M. H. Swenk -(June 25 July 25): The unusually large 1926-S7
winter wheat crop of Nebraska came through harvest without any
commercial damage whatever by the hessian fly.

Kansas J. W. McColloch (July 21): There has been no material change
in the Hessian-fly situation since my last report, I might say
that preliminary estimates indicate that this insect reduced
the wheat crop about 20,000,000 bushels.

WHEAT STE MAGGOT (Meromyza americana Fitch)

Nebraska M. H. Swenk (June 25 July 25): During the last few days in
June and the first two weeks of July, the wheat stem maggot
was responsible for some serious damage to wheat and rye in
the northeastern portion of the State, from Greeley County
northeast to Cedar County and northwest to Boyd County. The
injury was mostly confined to scattering heads through the
fields, but one Cedar County farmer reported that the pest had
destroyed about one-fourth of his crop of fall rye.

Wh A W SThAW WWOiM armolita gandis Riley)

Missouri L. Haseman (June 28): Farmers have been reportiAg small injury
from the work of the straw worm. It is no more abundant than
in most seasons but has attracted some attention.

ARMYWCRM (Cirphitsg unipuncta Haw..)

Kansas J. W. McColloch (July 20).- Last month I reported the -heat head
armyrorm as injuriqous in several .oIcalitifes. Field investigations
since then have show~ that most of the damage as due to the true
S armyvorm niWich: took on the' habits of the'Wheat-head armymorm.
In all cases a few vheat-h.ead atay"arms ,rere present.

... these thrips'from a \iheat' field, near. Paradise. He said the h-,eat
in thi's'field was poorer than in. djaent fields. From the num-
ber of specimens sent in this tThi'ps 'nas und'ibtedly very abundant



CHINCH BUG (Blissus I.ucopterus uSay)" "

-Ohio T TH. H.Par.ks .(July.25) 77 i'le .'r.e e:, ly ihatched chinch bugs' ere
found in the 'heat during he annual .heat. insect survey, no re-
port of damage has come from,any 's.ection of Ohio. The numerous
rains of the fall and spring have probably been responsible for
Sthe absence .f this pest.

Iorth Z. P.:.;etcalf. (June 1): This pest .is more abundant this.month ..
Carolina .. than-last; also more .abundant .this year than last.

A. i Thomas (Junei ): ..6n.June. .it.7as observed that this in-
sect ,as. doing serious damage .to grpin corn on a near-by farm.

199 -
C. H. Brannon (July 21): Has been especially destructive on
corn and small grains in Pitt and Robeson counties this year.
gmuch damage has been done to corn rop further east and south.

South H. C. Severin (July 18): No chinch bugs to speak of this year.
Dakota
Nebraska M. H. Swenk (June 25 July 25); Although the mortality of the
chinch bug was apparently not excessive during the past winter,
and the pest started the season with a menacing abundance in
many parts of southeastern Nebraska, the protracted period of
subnormally cool weather that occurred during May and June
slowed up the development of the first brood, while in most
localities timely cold rains proved fatal to a large percent-
age of the young of this brood. The net resultshas been far
less serious injury by this insect than was threatened at the
close of the winter. In only one area in the State did the in-
festation develop to the point of an outbreak. This area in-
cluded the whole of Lancaster County, about the northwestern
one-fourth of Gage County, the southern edge of Gage County,
and the southern edge and northwestern corner of Cass County.
In this comparatively limited area the bugs started moving on
July 2 and the movement continued for the next 10 days. Oil-
line barriers were constructed in many fields over this area
during the period mentioned, as the bugs moved from the wheat
into the near-by cornfields. Outside of this area the chinch
bug apparently did no serious or commercial .damage to Corn du-
ring the migration period.

Kansas J. W. Ma Colloch (July 20): Rains have checked the chinch..bug
and the injury this year is materially less than last year.
Scattered reports indicate local damage in several parts of the
State. The second brood is just beginning to appear.

EUROPEAN CORN BORER (Pyrausta nubilalis Hibn.)
Ohio L. H. Worthley (June 23): Scouting for the European corn borer
has been in progress only three days as the seasonal develop-
ment is late. Eggs are now present in the fields in consider-
able numbers and some larvae are as far along as the fourth
instar. The scouting up to this date has been limited to con-
firmation. of the presence of the borers in the counties on the
border of the quarantine area and the crews are reporting them
in these border counties in numbers at least as great as those
found in 1926.

CORN EAR WORM (Heliothis obsoleta Fab.)

Ohio T. H. Parks (July 25): Growers of early sweet corn in the Sci-
ota Valley report the heaviest damage in their experience from
the corn ear worm. Our first mess of green corn was 90 per








-200-

cent infested. This is unusual for early corn in central Ohio.
Perhaps the mild winter had. something to do .ith this as they are
not knonn to survive the..average .7inters in Ohio.

Kansas J. W. McColloch (July 20): The corn ear worm is somenihat more
abundant than usual. .The .isect, ;i:s-pres.ent throughout the State.
There has been considerable injury to the tassels of corn.at Larn

SOUTHEB dCOR. STAIK BORE (Diatraea zeacolella Dyar)

Maryland R. 1altoh (July 29):: n- :July:25th:,- r.. James ect urtrey of the
Bureau of Plant Industry. submitted specimens of corn stalks heavi
infested by. this species collected on fair grounds at Upper larl-
boro on. popcorn. He stated that: there had occurred total destruc
tion of from 400 to 500 plants on experimental plots. On July
26th, ,ir. Jamnes U.: Dennis of Trappe, Talbot~County, submitted spe
mens-of field corn.stating:that serious injury to it had been don
by the. insect, Both larva and pupa stages of the insect 7ere pre
sent.

Iorth C, H. Brannon (.July 20): Generally destructive to late-planted-
Carolina corn.

South J. 0. Pepper i(July -1):. Cornstalks infested'by this insect have
Carolina. been sent in- from Florence, County. TIn five stalks there were an
average of three larvae'per .stalk.

STALK.BORERR -(Papaipema nebris nitela Guen.)

Massachusetts A. I. Bourne-(July 25): From our:indications to date, the stalk
borer for -some reason :or another is:.not so abundant as is usually
the case. -

Ye7 York E. P. Felt (July 25): This insect has been unusually abundant
and destructive in 'idely separated sections of the State, norkin
in young corn and various thick-stemme, plants. Possibly a por-
-tion of the reports are du't6 the preseenlt keen interest in the
European corn borer and'its T90tk.'l

mIaryland P. -D4 Sanders (June-July): Corn has been injured seriously over
S.the State by t-he common stalk borer. Farmers are generally alarn
over-'its presence, "believing it to .bethe European corn borer. T
cold rainy spring no dotbt has made parasitism ineffective in hol
'ing the stalk borer in check, as.normally it is of slight concern
in this State. It also attacks 'dahlia and hollyhock.

Pennsylvania 1. F. Grorell (.July 5): On June 28 the -riter noticed the com-
mon stalk borer in about, the second anud third instars feeding
in corn that w7as about a foot high at Forth East. A report came








201 -

to this office on Jbly 1 that this insect is doing quite'a bit
of damage to flower beds in Erie.

Ohio E. W. Mendenhall (July 8): The stalk borer is very badlin Cham-
paign County in corn plants and some think they have the Euro-
pean corn borer; but when investigation is made we find it is
the common stalk borer.

T. H. Parks (July 25): Damage from the stalk borer has been more
abundant this season than usual. Specimens have been received
almost every day with the fear expressed that they may be the
European corn borer. Larvae are about full-grown at this writ-
ing.

Indiana H. F. Dietz (June 28): The common stalk borer is being reported
within the last few days, June 22 to June 24. Most of our rec-
ords have come from Marion County where in a number of cases
small garden lots have been seriously injured by unusual num-
bers of these worms. At Danville this insect was found tunnel-
ling wheat, and in Madison County over 50 per cent of a half-
acre plot of sweet corn was destroyed.

In city flower gardens this borer has also been reported on
such flowering plants as cosmos, dahlias, and zinnias and such
truck crops as potatoes and tomatoes.

J. J. Davis (July 19): One of the outstanding pests of the month
was the common stalk borer. Reports were first received June
22 and have continued up to the date of this record, being most
numerous the last few days in June and first week or ten days
in July. Greatest damage reported to jcorn, but also feesaeet
and popcorn. Next ctop in importance was tomato. Other crops
attacked included potato, wheat, oats, mint, hollyhock, dahlia,
and rhubarb, most of the reports coming from the northern two-
thirds of the State. The general prevalence of this borer
throughout the State and the small sixe of the corn tvf resulted
in conspicuous losses to corn growers and others.

H. F. Dietz (July 21): Reports of the stalk borer, fentinue to
be received from various parts of the State. The hosts, of
course, are quite variable and whenever the insect is found in
corn the writers immediately think they have the European corn
borer. Reports of this insect in dahlias, tomatoes, asters,
and zinnias are common.

Michigan R. H. Pettit (July 18): This is the worst year so far that we
have ever had with the common stalk borer. It is sent in some-
times a dozen times a day with the request for information con-
cerning it.






202 -

Iowa C. J. Drake (July 12):' The common stalk borer is unusually abuz
dant in Iowa this year. pver 100 different kinds of plants
have been found infested by the. stalk borer at Ames. Specimens
have been received from almost every county in the State, and
in some counties a considerable quantity of corn has been badl3
injured or even entirely destroyed.by the insect.

L. Haseman (June 28): Throughout the month the outstanding in-
sect so far as inquiries'are concerned has been our common na-
tive stalk borer. Farmers have suspected that it might be the
European corn borer. It has been unusually abundant this montl

Nebraska M. H. Sweik (June 25 July 25): Complaints of injury by the
stalk borer, that began to be received during the second week
in June from southeastern Nebraska, as mentioned in my last re-
port, increased to the status of an.outbreak during the last
week in June and the first three weeks in July. Complaints of
injury were received from practically every county in Nebraska
lying. east of the 98th meridian, and in the Platte River Val-
ley the area of injury extended west to the 100th meridian.
Over one-half of the complaints referred to injury to corn,
which in some instances assumed quite a serious aspect; other-
wise, the-complaints referred mainly to injury to potatoes, to-
matoes, and thick-stemmed flowers, like hollyhock, etc.

Kansas J. W. McColloch (July 20): The stalk borer has been a predom-
inating insect in our corrbspondence this month, owing to the
fact t at every one is looking for the European corn oorer.
kany farmers are reporting, heavy losses from this pest. In a
few cases the damage has been severe enough to cause abandon-
ment of the crop.

Iowa C. J. Drake (July.29): A telegram July 29 reads "Big armyworm
outbreak in Hardin and Franklin Counties."

YELLOW-STRIPED ABMYWORM (Prodenia ornithoalli Guen.)

Iowa C. J. Drake (July 12):! The cutworm Prodenia ornithoaslli OGena
has been found in considerable numbers in Story, Woodbury, and
Webster Counties during the first part of July.

Mississippi R. W. Earned (July 25): The yellorw-striped armyworm ranks sec-
ond in .importance among the cutworms in the overflowed areaa.
Between May 16 and Jly 21,. reports with specimens were receiv
ed from Adams, Bolivar, Tallahatchie, Warren, Washington, and
Yazoo Counties,

CUTWORMS (Noctuidae)

Iowa C. J. Drake (July i2): Cutworms (various species) have been un-
usually abundant in the'State this spring. A. number of fields
of corn were badly injured or even entirely destroyed.







203 -
BLACK CUTWORM (Agrotis ypsilon Rott.)

Indiana J. J. Davis (July 19): Cutworms have been unusually abundant
the past month. Most of them were apparently the greasy cut-
worm. The first of these late cutworm reports came from Ko-
komo June 27 where 20 acres of corn were said to have been de-
stroyed. Late reports of damage to corn came from Peru, July
2; 'inamac, July 3; Muncie, July 4; Newburgh, July 6; Martins-
ville, July 7; Rossville, July 9; and Terre Haute, July 14.

Nebraska M. H. Swenk (June 25 July 25): During the second and third
weeks in July several reports-were received of cornfields be-
ing injured by the greasy cutworm, boring into the bottom of
the stalks of young corn and killing the plants. This injury
assumed its most serious development in York County. One 40-
acre field near Gresham fad about one-third of the stand on
several acres taken in this way, while another field of 35
or 40 acres near Lushton suffered a loss of about 10 per cent
of the stand becau of this injury.

Miadidiippi R. W. Harned (July 250: Agrotis ypsilon Rott. continues to be
the most important cutworm in the counties that were recently
flooded. Between May 25 and July 19, reports of injury by this
species accompanied by specimens were received from Bolivar,
Yazoo, Quitman, Washington, Warren, Grenada, Tallahatchie,
Adams, and Sunflower Counties,

SESSER CORN STALK BORER (Elasmopalpus lignosellus Zell.)

Louisiana T. E. Holloway & W. E Hale# (June 29): One field of corn near
Gulfport was reported by various inspectors as having a pecu-
liar injury. No specimens could be found by anyone, but it ap-
pears that the damage was done by the lesser corn-stalk borer.
The stalks were in many cases almost girdled at the surface of
the gpound, so that a strong wind caused them to fall over.

Mississippi R, W. Harned (July 25): Although a month ago we were receiving
complaints every day in regard to the lesser corn stalk borer,
during the past three weeks only three lots of specimens have
been received. These came from Newton County on July 15 with
the report- that they were seriously injuring corn, and from
Lee eounty on Julj 23 where they were attacking corn, and from
Jefferson County on July 21 where they were attacking peas.

LINE CORN BORER (Hadena fractilinea Grote)

New York E. P. Felt (June 27): We have just learned of a heavy infesta-
tion in a cornfield in Broome county, (July 25): The lined corn
borer has been injurious to corn on recently planted sod in Al-
bany, Columbia, Rennslaer, Broome, and-Oneida Counties, and in
some instances caused considerable damage.









SMARTWEE PBORER (Pyrasta -ainsliei Hein.)

complained of during middle and late July from an area in souti
cadtral Nebraska enclosed between Buffalo, Gasper, and Lincoln
Counties. Many fields of yotnger corn have been largely des-
troyed by.this pest, and in northern Gosper County about three
fields out of- every four are reported to be more or less ser-
iously infested.
Kansas J. W. McColloch (July I): This aphid was sent in from Hiawatha
with the information that it was bad in a cornfield there.

ALFALFA

ALFALFA WEEVIL (Phytonomus posticus yfTiPls,

Wyoming M. EH Swenk (July 18): You will be interested to know that our
survey last month showed the alfalfa weevil to have advanced
from about 40 miles west of the Nebraska-Wyoming line to about
8 miles west of that line. We failed to find the weevil in
Nebraska at any point.

SOYBEAN

POTATO LEAFHOPPER (~Epoasca fabae Harr.)

North Z. P. Metcalf (July 21): This pest has proved especially des-
Carolina tructive to soybeans and peanuts early in the season.

COWPEAS

COWPEA CURCULIO (Chalcodermus aeneus Boh.)

year than it has been for four or five years. It is doing
considerable damage in some cowpea fields.
SORGHUM

KAFIR ANT (Solenoosis molesta Say)

Kandas J. McColloch (July 20): On June 20 the ants were reported
destroying the planted sorghum seed before germination at

Mississippi R. W. Earned (July 25): Spittle insects are now unusally abun-
dant on Johnson grass in the vicinity of A. & M. College.

A SOLITARY BEE (Andrena perplexa? Smith)

Maryland P.' D. Sanders (May 14): The injury to the lawn was a result of
the nest-digging of the female bees. In an area one yard square
63'nests were counted. It is of interest to note that this
same species was present in an adjacent lawn in injurious num-
bers in 1924. A.treatment of carbon disulphide emulsion as rec-









208.-.
ommended for the: Japanese beetle gave practically 100 per cent
kill. The bees did not reappear in 1925. In 1926 the infest-
ation began to build up as the bees were rather numerous but
not sufficiently abundant to be injurious. In 1927, however,
the infestation was severe. A treatment of carbon disulphide
emulsion :applied .with a garden sprinkler gave excellent control


FR U I T I N S EC TS

GENERAL

APHIIDAE

Massachusetts A. I. Bourne (July 25): Orchard plant lice are very abuhdant
all over the State.

Missouri L. Haseman (June 28): The month has been notorious for the
abundance of plant lice on grape, apple, and plum.

LEAFHOPPERS (Jassidae)

Indiana H. F. Dietz,Jfly 21): Leafhoppers, species not determined, hav
caused conspicuous ialformation on apple, plumand Norway ma-
ple nursery stock at Indianapolis, Terre Haute, and other scat
tered towhns in the southern half of the State.

APPLE

APHIIDAE *

Indiana H. F. Dietz (June 28): The only apple aphids that seem to be
.abundant are the green apple aphid, and the woolly apple aphid
'Schizoneura lanigerunm Hausm.

B. A. Porter (July'22): Early in the season all species of aph
ids were comparatively scarce in apple orchards in southern
Indiana. Beginning about June 1, the apple aphid Aphis poi
DeG. increased to tremendous numbers in many orchards, and is
still abundant in the vicinity of Vineannes.

Michigan R. H. Pettit (July 19): Apple aphids have curled the leaves
everywhere in the State, and the injury both to the foliage
and to the fruit has been very severe. Aphids of all sorts
have been plentiful and troublesome.. Aphids have been ex-
tremely plentiful on Norway maple, smearing the leaves with
honeydew and causing the foliage to fall very freely. The
leaves are now many of them falling from the trees.

Pennsylvania, iTc- York, brnd -c Engl-hnd.

Tennessee A. C. Morgan (July 20): The eastern tent caterpillar has been
unusually abundant, t'tsr unsightly -vebs completely covering
many trees in the vicinity of Clrksvillc.

APPIE. CURCU'LIO (Thchyptcrollus Qiiadrigibbus Say)

Missouri L.. Sascman (June 28): .Adults of 'the sxcond .generation began
omceging Juno .20 to 23.

PLUM CURCULIO (Coaotracholus nonuphar Hbst.)

Indiana H. F. Dietz,:-(June 2S): Infestation :by the plum. curculio is un-
usually severe. Around Indianapolis on such apples as bear frui
the -apples sho-'rfrom four to eight stings jper fruit. In the Pao:
Mitchell-Orloans fruit district about SO per cent of the cherries
of which there is a comparatively light crop, are infested and
throughout thbe -Sthte, taking the reports that have been received.
this insect is more abundant on cherries than it has been for
several years.

APPLE SEED CHALCID (Syntomaspis druparum Boh. )

Massachusetts A. I. Bourne (July 25): The first flies of the apple seed chalci
wore collected in ca;es in the college orchard July 4 and 5.

ROUND-HEADED APPLE TREE BORER (Saperda candida Fab.)

Wecst F. E. Brooks (June 27): Bootles arc unusually abundant and are
Virginia at present ovipositing in apple and other host trees. The abund-
: ance of the beetles appcrs to be due to the scarcity of wood-
peckers in orchards during the past viinter. A heavy crop of
beechnuts last fall supplied rintcr food for these birds and they
remained in the -roods to an unusual degree. The donny woodpec
,:hich is normally destructive to those borers, scarcely left the
-aoods during the iinter to obtain food in orchards or at artifi-
cial fcoding stations. In rather extensive collecting of
rcaring material of these borers in early spring not an example
of destruction by roodpeckers ras observed. Often 25 per cent or
more of the full-gro-n larvae are removed from their pupal quart
during the .-intcr by woodpeckcrs.

APPLE MAGGOT (?haolctis pomonella Talsh)

Iassachusctta a. I. Bonrno (July 25): July 5 the first flies of the railroad
worm, or apple maggot, wcro collected in the orchard. Up until
about the 15th they -:erc not collected in any large numbers. By
the 15th. horever, both in our c-gc experiments and in the orchl









211 -
-;o found them to be prcfrt in considerable abundance, indicating
the probabilityythat at least early varieties would be fully as
badly hit as was the case last year.

JAPANESE BEETLE (Popi"~ Aijaponica Neowm.)

few Jersey L. B. Smith (July 22): Scouting for the Japanese beetle outside
and of the area now under quarantine has been in operation about a
'aryland wook. It is too early to tell whether there will be extensive
spread of the general infestation but a strong movement to the
south is indicated.

SAi JOSE SCALE (Aspidiotus perniciosus Comst.)

Massachusetts A. I. Bourne (July.25): The crawling young of the San Jose scale
began escaping from under the parent scales July 4 and 5.

Indiana B. A. Porter (July 23): First-brood crawlers appeored a'. Tit
June 1, but have not been particularly abundant. Very little spot-
ting of the fruit has been observed as yet.

POTATO LEAF HOPPER (Empoasca fabac I0rr.)

Indiana B. A. Porter (July 23): Unusually abundant, -nd has caused seri-
ous curling, stunting, and burning of terminal gro-'th of apple.

EUROPEAN RED MITE (P.ratctranychus pilosus Can. & Fa:nz.)

Connecticut Philip German (July 23): In spite of the cool wcathcr a.nd hcavy
rains until July, the mite is causing serious damago in some or-
chards.

Indiana H. F. Diotz (July 21): Heavy infestations of the Europoen red
mite vwro found at Indianapolis.

EASTERN FIELD WIRE7ORIM (Pholctes agonus Say)

Maine J. H. Hawkins (May 14): Some elatcrids 'Tre i akef at the Experi-
mental Farm at Highmoor. They etro found in a young apple orchard
climbing around the trees. It -was reported that they vwere eating
the buds. This may or may not be true, but they were present there
in some numbers during the latter part of April. Unfortunately
I received only throe. I am sending two of them to you. If you
can conveniently give me the identification of these beetles, I
rould very much appreciate it. (Determined by J. A. Hyslor).








-212-

Georgia Snapp & Swingle (July 21): In 1925 the oriental peach moth in-
festation in the Fort Valley section of the Georgia peach belt wa
comfined to parts of six commercial orchards. In 1926 the insect
could be found in parts of only three of these orchards. A su
vey during the past week revealed the fact that the imsect has
spread this year to commercial peach orchards over practically the
entire Fort Valley district. It nas found throughout orchards to
a point 12 miles north, 15 miles south, 6 miles east, and 2 miles
west from the city of Fort Valley.
Frequent rains during the fall of 1926 and the early summer
of 1927 caused rapid twig growth, which furnished an abundant
supply of food for the development of the insect.
The infestation is very light throughout the area described
above.

PLUM CURCULIO (Conotrachelus nenuphar Hbst.)

Massachusetts A. I. Bourne (July 25): Probably the most serious pest of fruit
to date, at least the one that is causing the most anxiety to
growers, is the plum curculio. It appears to be present in eves
greater abundance than last year, and even in well sprayed or-
chards has done a large amount of injury.

Maryland P, D. Sanders (July): The plum curculio has been unusually abund
ant this year in commercial apple and peach orchards. The failur
to control it is generally attributed to the abundance of the
species and the excessive rain during the spraying season which
tended to wash off the arsenical.

Georgia 0. I. Snapp (July 20): The peach season is over in Georgia after
the shipment of around 12,000 cars. The curculio infestation was
heavier this year than at any time since 1923. There were two
generations, the second generation attacking the U1bertas. The
insect gave the most trouble in poorly-cared-for orchards, and in
those that received an irregular schedule of sprays

hissouri L. Haseman (JuLe 28): Adults of the second brood began emerging
June 25 to 28.

Texas F. C. Bishopp (July 26): Although the first generation of the
plum curculio did not appear to be especially abundant,the second
generation has caused heavy damage to midsummer peaches. As high
as 50 per cent of the ripening fruit has been destroyed in some
instances, and many peaches were found to be infeste with 3 or
4 larvae. The larvae have been emerging from peaches during the
past two weeks.

Georgia Monthly Bulletin, Bureau of Entomology, No. 157, May, 197 : 0.
Snapp, in charge of the peach insect laboratory at Fort Valley
vrites that the first adult curculios there emerged from the soi









-213-

on May 24, vwhich is the earliest first-emergence date in seven
years. Tno full broods are anticipated, and he is expecting
second-brood larvae to infest the Hiley peaches this year. The
Hiley is a midseason variety.

TARNISBED PLANT BUG (Tgus rratensis L.)

Indiana H. F. Dietz (July 21): Tarnished plant bug injury was found
abundant on peach at Burns City, Terre Haute, Washington, and
Vincennes.

YORTHERN LEAF-FOOTED PLANT-BUG (Leptoglossus oppositus Say,

Georgia 0. I. Snapp (July 23): The plant bug responsible for most of
the damage to peaches in Georgia this year as reported on July 20
has been identified by Mr. McAtee as Leptoglossus op-ositus.

CHERRY

CHERRY SLUG (Caliroa cerasi L.)

Indiana J. J. Davis (July 19): The cherry slug was reported destructive
to cherfy from Lincoln, June 30.

BLACK CHERRY APHID (Myzus cerasi Fab.)

Indiana H.F.Dietz (June 28): The black cherry aphid has been abundant in
Indianapolis, Danville, Greenaood, and Clermont.

Michigan E. I. McDaniel (July 18): The black cherry aphid has been unusu-
ally plentiful this year and has completely ruined the crop so th.f
it was left unpicked in parts of Shiawassee County.

CHERRY MAGGOT (Rhagoletis cingulata Loew)

Michigan R. H/ Pettit (July 1l): An causual situation arose this year in
the case of the white-banded cherry fruit fly. Our field cages,
maintained for the purpose of determining the dates of emergence
of the adult flies in the southern part of the cherry belt, actu-
ally produced adults this year after a portion of the cherries hac
been picked and canned. It would seem, therefore, that the cold
season, at least on this occasion, delayed the insedts more ef-
fectively than it did the fruit. At any rate, no sprays were re-
quired in the southwestern part of the State in order to hold the
white-banded cherry fruit fly in check.

PLUM

RUSTY PLUM APHID (Hysteroneura setariae Thos.)

Indiana H. F. Dietz (June 28): The rusty plum aphid has been recorded
abundant in Indianapolis, Danville, and Greenwood.

PE AR

PEAR PSYLLA (Psvlla pyri L.)
Connecticut W. E. Britton (July.19): Attacking pear. Many leaves now brown
and falling. Both fruit and leaves blackened by sooty fungus
growing in the honeydew.

PLANT BUGS
Georgia 0. I. Snapp (July 20): Squash bugs, southern green plant bugs,
etc., have been very much more numerous in Georgia this year.
They have attacked peaches:, and are responsible for many ill-
shaped and gnarled fruits this year.

APPLE APHID (Aphis pomi DeG.)

Misissippi R. 7. Harned (July 25): Reported on pear at Lumberton on July 5.

QUINCE

SAN JOSE SCALE (Aspidiotus perniciosus Comst.)

Ohio E. Mendenhall (July 5): The Japanese quince (Cydonia) on
the large estates in Springfiald are badly infested with the San
Jose scale.

PEACH

PEACH TWIG BORER (anarsia lineatella Zell.)

Indiana H. F. Dietz (July 21): Injury by the peach twig borer was found
at Burns City, Terre Haute, Washington, and Vincennes.

Texas F. C. Bishopp (July 25): Very few peach twig borers have been
evident in the vicinity of Dallas, until last week, wen the
larvae were found attackingin7 ripening lberta peaches to some
extent.

ORIENTAL FRUIT iOTH (Laspeyresia molesta Busck)

Connecticut Philop Garman (July 23): About the same infestation as last year.
The early season seems to have been unfavorable. Warm weather in
July brought out adults in large numbers.

Ohio T. H. Parks (July 25 ): Back-yard trees in the city of Columbus

During the month of May the Los Angeles County Insectary produced
and liberated in the Citrophilus-mealybug-infested citrus orchards
of the County, 1,S12,000 Gryptolaemus according to H. '.. Armitage,
Deputy Horticultural Commissioner, Los Angeles County. These,
combined -;th the half million liberated during April, have made
it possible to cover at an early date all properties seriously
infested -ith the mealybug in Los Angeles County, -hich should
permit the control of the pest -!ith a minimum of injury to the
trees and fruit. These beetles have been distributed over 361 in-
fested properties representing 3,455 acres of citrus scattered
through the Rivera, Don-.ey, North Thiittier Heights, Covina, Bald-
win Park, San Dimas, LaVerne, Claremont, and San Fernando areas.
S.ealybug infestations have been some-:hat heavier this season.
Short hot spells have aided the development of the mealybug
.7hile the prolonged cool --reather has retarded the activities of
the Cryptolaerm s and other native natural enemies. However, the
Cryptolaemus are nor shoin.g marked activity and rapi control of
the mealybug for this season is anticipated..;-

per cent of the strawberries having been destroyed.

RED SPIDER. (Tetranychus telarius L.)

California Monthly News Letter, Los Angeles County Horticultural Commission,
(June 18): Damage by the common red spider has caused a loss of
approximately one-half of the second crop of strawberries in the
Inglewood and Hawthorne districts according to Mr. Anzai, presi-
dent of the Japanese Berry Growers' Association. As the spider
damages the under side of the leaves, it is impossible to attempt
control without damaging the fruit. Very poor results have been
obtained in past years with the oil sprays and sulphur dusting.
For this reason very few growers have attempted any method of
control this year. Aside from the injury to the plant, the dam-
age to the appearance of the affected berries is such that they
sell for as much as 75 cents a crate less than unaffected berries
of good appearance.

Virginia J. E. Graf (July 7): Dr. Harter, of the Bureau of Plant Industry
reported yesterday that the bean plants at the Alington Farm, Va
showed insect injury. Upon investigation by . ihite of this
office the insect responsible for this injury tas definitely de-
termined as the Mexican bean beetle. It has also been reported
from Norfolk. (July 29): Mr. Poos, of the Virginia Truck Experi.
ment Station reported on July 13 that he collected larvae, pupae,
and adults on Kentucky Wonder beans in three baokyard gardens.
He also states that it has been found in Prince George County and
-several of the counties lying between the Rappahannock and Poto-
mac Rivers.

North R. 7. .Leiby (July 6): An unprecedented spread of the Mexican
Carolina bean beetlo appears to have taken place this spring and early
summer. The line of infestation run in the fall of 1926 extended
from Union County northeastward through Alamance and Casnell
Counties. The outlying easten points where the beetle has been
found are Raleigh in Wake County on July 5, and Lumberton in
Robeson County on June 27, which are approximately 50 and 75
miles respectively east of the-1926 line. Scouting to determine
other points of infestation is now being done by J. A. Harris,
Assistant. The first-generation pupae are now beginning to ap-
pear at Raleigh.

C. H. Brannon (July 20): The Mexican bean beetle has spread
a eastward into 7ake, Robeson, and Cumberland Counties.

South J. 0. Pepper (July 19): C. O. Eddy reports first-generation
Carolina adults of the Mexican bean beetle nor emerging in large numbers.
Injury is increasing rapidly. The area of damage in the infested
zone is increasing .here eradication occurred during succeeding
dry years.

Indiana J. J. Davis (July 19): The Mexican bean beetle has been more
destructive and widespread this season than ever before. The
northern range of destructiveness -seems to be Indianapolis and
Richmond and the nestern range, Owen, Green, Iartin, and Dubois
Counties.

E. E. Dietz (July 21): The Mexican bean beetle has been reported
as destructive from Jefferson, Henry, and 07en Counties.

Michigan R. H. Pettit (July 21): The Mexican bean beetle has been:
reported from Lambertville, Monroe County.

Aississippi R. W. Harned (July 25): Specimens of the southern green plant
bug were received from Port Gibson on July 8 rith the report that
they were seriously damaging pole and lima beans. Specimens were
also received from Turnbull on the same date with the information
that they were causing serious injury to tomatoes and lima beans.

vew York Rodney Cecil (July 5): The seed corn maggot has caused consider-
able damage to the bean crop in this section (Geneva). A series
of counts in various fields of beans show a loss of from 5 to
30 per cent. The cool weather seems to have delayed emergence of
the flies, and beans planted after the 15th of June suffered the
most from the maggot. June 15 to 20 is usually considered the
best date for planting beans in this section to escape injury from
the seed corn maggot, but this year beans planted between the 15th
and 20th suffered the most injury.

PEAS

PEA APHID (Illinoia psi Kalt.)

isconsin J. E. Dudley, Jr. (July 25): Conmbined attack of all the aphid's
enemies was not able to prevent the daily increase of aphids
until a severe wind, and rain storm on July 11 reduced the infesta-
tion until at the present time it is almost negligible. Another
rain on the 16h further reduced the infestation from where it
has not again risen.

Iowa C. J. Drake (July 12): The seed corn maggot did a considerable
amount of damage in a melon field near Fayette during the months
of May and June.

Michigan R. H. Pettit (July 25):. For several years reports from the
Heinz Pickle Company have come in, complaining that maggots were
working in the roots of cucumber vines. Finally some of these
maggots were obtained in a living condition and bred. The adults
prove to -be Hylemyia cilicrur- as determined by C. T. Greene,
United Stated Bureau of Entomology. Specimens have been reared
from Holland, Mich., and also from a farm almost on the line
betveen Indiana and Michigan.

DCa* ains all parts of Spartanburg County and is causing injury.

STRIPFD CCUMBER BEETLE (Diabrotica vittata Fab.)

Wisconisn J. E. dudley, Jr. (June 24): Owing apparently to enforced in-
activity of this insect, itich emerged from hibernation early
in I'ay, .beetl-es with the advent of warm weather are exceedingly
ravenous and are concentrated on corners and ends of fields of
oucurbits. where the plants attacked are completely destroyed in
one night. The spread of beetles generally over cucurbit fields
has been very slow this spring. Ground beetles and several
species of ants attack dead beetles so quickly that it is almost
impossible:to'determine per cent of kill unless observations are
taken hurly. Occasionally apparently normal beetles hiding
under. clods of dirt.are found attacked by these enemies.

troublesome this year.

Wisconsin J. E. Dudley, Jr. (June 24): Adults issuing from 10-foot check
cages over cull onions at the rate of about 75 per day. In some
cases 300 have already issued. Excessive rains in May and early
June apparently drovned out almost 100 per cent of maggots in
certain parts of fields and cull rows which were lowest.

Iowa C. J. Drake (July 12): The onion maggot has been reported from
Clear Lake and St. Ansgar. Injury has not been extensive.

BEET

BEET ARMYfWCM (Laphygma exigua Hubn.)

California A. C. Davis (June 30): In Norwalk practically every plant has
one or more worms, and about one in 25 is defoliated. In Hunt-
ington Beach about one plant in 10, on an average,is infested.
Some areas more heavily infested than this.

J. C. Elmore (July 5): The outbreak of the beet armyworm which
7as reported several days ago seems to have subsided rather sud-
denly. Very few larvae can be found on the plants at this time.
Pupae were found to be numerous in the soil two to three inches
from the surface where the infestation has been serious. One
species of Calosoma (cancellatum)? was taken and several carabid
larvae were found feeding on the pupae.

BEET WEBWOCRI (Loxoste e sticticalis L.)

Yorth C. N. Ainslie (July 2): The spring brood of adults is appearing
Dakota in greater numbers than for several years. Emergence has been
delayed by the abnormally cold spring. The sugar-beet growers
anticipate trouble ffom this pest this season.

various"parts of the State as possibly the European corn borer.
It was always sent in from wild parsnip.

PEPPER

PEPPER WEEVIL (Anthonomas eugenii Cano)

California J. C. Elmore (July 1): The first field infestation of the pepper
weevil this year has been found near Santa Ana. Overwintering
adults were found early in April on overwintering plants, but
none have been found since in Orange Coonty until July 1. The
infestation referred to above is very light at this time. (July
7): A 4-acre field of pimento peppers adjacent to a field of
overwintering plants where the weevils were numerous in April of
this year was found to be infested. Thirty larvae were taken
in butts. No adults were taken. About ten days of warm weather
have had some effect on the development of the weevil no doubt.
Other infestations are expected in other localities. (July 14):
The pepper weevil has been found to be well distributed over the
pepper growing section of Orange County in the last few days,
and indications are that the losses will be heavy in a large num-
ber of fields this year. The adults of the first spring genera-
tion have just begun to emerge.

BEET EB7WORM (Laphygma exigua bbn.)

alifornia J. C. Elmore (June 30): Generally distributed in pepper fields
in the county, but numerous in certain areas. The larvae have
attacked every plant in parts of some fields, eating out the more







-222-

,tender leaves and in some-cases completely defoliating the plants.
Hore damage is not ced near p gweed patches. The pupae of some
dipterous parasite are commonly found near dead larvae of the
armyworm. Laphygma exigua has been found on peppers for three
years, but not in such destructive numbers before,

i: A. E Gampbell (July 1): Larvae are'feeding mostly on weeds,
particularly Amaranthus, but to a considerable extent on young
peppers. In several fields damage is considerable, and growth
will be checked, but there is not entire defoliation. Worms are
migrating from weeds to peppers in several places. Observed on
weeds and peppers in Los Angeles County, also 800 acres of pepper
affected.

survival was recorded this year at Florence, S. C., College Sta-
tion, Tex.., Aberdeen,: N. C., Raymoid, M iss., Rocky Mount, F. C.,
A. & :~. College, Hiss., Poplarville, hiss., and Holly Springs,
Miss., while a greater survival was recorded in 1926 at Auburn,
Ala., Baton Rouge, La,, and Experiment, Ga.

IYorth R. W. Leiby (June 16): In the southern portion of the State ex-
Carolina aminations were made in 12 fields on June 6 and 14, of a total of
5065 plants and 43 weevils were found. This was an average of 1
weevil to 118 plants. The first weevil was found at Tarboro in
the northern portion of the State June 8, 'which was 18 days earlie
than in 192'. From June 15. to 30 in the Aberdeen section (Robeson
and Scotland Counties) a total of 2,900 'squares were examined in 9
different. fields-of which 294 were punctured. This was an average
infestation of 10.1 per cent, the range being from 0 to 24 per
cent. The plants averaged from 3 to 5 squares each. In the
Rocky lount section plants average about one square each. From
Hay 26 to June 29.a total of 20,100 plants were examined and 4
weevils were found. This is an average of 1 weevil to 5,025 plants

C. H. Brannon (July 20): The cotton boll weevil is generally
more destructive than last year.

South C. O. Eddy (July 2): No weevil activity has been noted in the sec

1.5 per cent, and inz 1925 it was 13.6 per cent.
C. O. Eddy'(July 19): Boll weevil infestations small and scat-
tered in the Piedmont section.

georgia 0. I. Snapp(july 1): Weevils are fairly abundant in Houston and
in adjoining and near-by counties. There has already been some
dusting with calcium arsenate in the Fort Valley section for
weevil control. Some rain ;was reported on 17 days during June,
and with a good source of weevil infestation cotton growers are
anticipating considerable .trouble from the insect this year.
(July 20): The boll weevil is more abundant than usual in Middle
Georgia. Considerable damage is being done in some fields. The
almost daily rains since the sixth of June have materially aided
in the development of this insect in this region.

rennessee S. P. Dent (June 27): Reports indicate a rather widespread
light infestation of weevils near Somerville.

abama J. M. Robinson (June 30): The boll weevil is very active at Auburn.
The first-generation adults are out feeding on and puncturing the
squares. (July 5): A summary.of reports from county agents and
vocational agricultural teachers shows that there is a general and
unusually heavy ,eevil infestation in the central and southern
parts of the State. In-southern Alabama cotton is well advanced
for this season of the year, mature bolls being common. The first
generation-of weevils are emerging and some are now depositing
eggs. Weather conditions and size of cotton are such as to assure
almost 100 per cent emergence of this generation of weevils. On
July 27 and 28 the average infestation was 11.9 per cent on dusted
plats at Auburn compared to 20.4 per cent on the undusted plats.

ssissippi Miss. State Plant Board (July 4): The heavy weevil injury reported
by the State Plant Board a week'ago has continued during the past
w.eek, according to observations made by inspectors of the Board on
99 farms'in 23 counties. The general prevalence of weevils is
shown by their presence on 82 out of 99 farms. Infestations run-
Sning above 20 and 30 percent were reported from several counties.

oaisiana W. E. Hinds (June 14): The first weevil was found in the field
near Baton Rouge on May 30 vhen a female was captured and feeding
punctures made by her. were noted but no egg punctures were found.
Cotton has been blooming since June 1 on some of the cotton
breeding plats particularly but no other weevil infestation evi-
Sdence has been noted thereon.

B. R. Goad (July 4):' On July 4 square examinations were made in


I









9 fields of cotton that were not overflowed. The punctured squares
in these fields ranged from 1 to 11,8 per cent, the average being
7.1 per cent.

Texas H. J. Reinhard (June 16): In the lower Rio Grande Valley the boll
:7eevil is doing considerable injury in the irrigated section at
La Feria. No complaints of injury have been received outside of
this area.

F. L. Thomas (July 5): Ideal -weather for the multiplication of
weevils has prevailed for the past four weeks. Infestation is now
very heavy in some sections, amounting to 50 per cent and in some
fields in the wooded sections 100 per cent. It has been very un-
usual weather for Texas. (July 13): Boll-weevil infestations range
from 0 in young cotton to 95 per cent on large plantations in the
Brazss Bottom. An aeroplane company has three ships working in this
area and plans to dust 11,000 acres. Boll worms are also just be-
ginning to become abundant in many sections of central Texas,. Fif-
teen counties in eastern Texas report boll-weevil injury. The crop
in Williamson County, one of the largest cotton-growing counties
of the State, seems to be very'good with very little boll weevil
injury.

F. C. Bishopp (July 26): Boll weevils are prevalent throughout
northern Texas, and eeme report them to be sufficiently numerous
to cause a large percentage of the sQuares toell. Continued rains
are promoting large stalk growth, and if these continue weevil in-
jury may be rather heavy.

COTTON FLEA HOPPER (Psallus seriatus Reut.)

North R. 7. Leiby (June 14): Cotton flea hoppers are fairly abundant in
Carolina the section-from Red Spring to Laurinburg, with a number of blasted
sQuares evident. (July 1): No cotton flea hoppers observed but
some supposedly hopper damage has been seen at Rocky Mount.

South C. 0. Eddy (July 2): Cotton flea hoppers developed in large num-
Carolina bers on evening primrose and some of these migrated to cotton, caus-
ing only a very small amount of damage. Infestation of hoppers on
both evening primrose and Qlon is much less than before the long,
cold, wet weather of the last of June. Infestation on croton is
building up slowly. (July 19): The cotton flea hopper is develop-
ing in moderate numbers on croton. Very few are on cotton and in-
jury is negligible.

E. W. Dunnam (July 5): We have received no complaints of hopper
damage in this section (Florence) of the State this season.

Georgia 0. I. Snapp (July 1): 7e have very few complaints of the cotton
hopper in middle Georgia this year.






-231-

Tennessee S. P. Dent (June 27): Within the past week cotton hoppers have
become general. Today 100 plants were examined in four fields
and hoppers found to be plentiful. From 30 to 75 per cent of the
forms have been destroyed by them.

Alabama J. i. Robinson (June 30): The cotton flea hopper is not appearing
in Large numbers in Alabama as yet. (July 5): Cotton flea hop-
pers have not shown up in southern and central Alabama in very
large numbers,as only a few adults and nymphs have been found,
either by weeping or close' observation.

Mississippi Miss. State Plant Board (July 4): Though cotton hoppers are now
present in fields, only very slight injury has been reported this
season, which is in marked contrast to the heavy damage occurring
on the same date last year.

Texas F. L. Thomas (July 5): Complaints of cotton flea hopper damage
have been received from only one section of the State and from
there for only a short period. This was in the vicinity of
T harton County.

A Correction.

The note in the Insect Pest Survey, Vol. 7, No. 4, p. 121,
referred to the entire number of flea hoppers collected from six
different experimental plats located at College Station, Corpus
Christi, San Antonio, Troup, Jcslaco, and -harton.

COTTON APHID (Aphis gossypii Glov.)

North R. W. Leiby (June 14): Lice are generally present on cotton about
Carolina the same as at this season in other years.

Mississippi R. W. Harned (July 25): Aphis gossypiii was reported on cotton
at Michigan City on June 20.

Louisiana 77. E. Hinds (June 14): Cotton plant lice are abundant in spots
but their parasites and predators are also abundant and should
control the early-season infestation.

Texas H. J. Reinhard (June 16): The first and only complaint this sea-
son of louse injury to cotton was received June 15 from Needville
in Fort Bend County.

COTTON LEAF WORM (Alabama argillacea iibn.)

ennessee T. F. McGehee (June 15): One specimen of leaf worm was received
from S. P. Dent, county agent at Somerville. Mr. Dent collected
four specimens at Somerville on June 15.

exas F. L. Thomas (July 5)! Leaf worms are now aiundant in some fields







.232-

in the vicinity of Corpus Christi. Cotton that has been stripped
by leaf worms is common in the territory as far northward as
San Marcos and eastward to Houston. A definite report was also
received today of the presence of one moth and one caterpillar
in Hill County.

THRIPS (Thysanura)

South C. 0. Eddy (July 2): Cotton seedlings were injured more severely
Carolina by thrips than all other cotton insects throughout most of the
Piedmont section. Three species were found on this injured cot-
ton. Dwarfed seedlings having ragged and malformed leaves were
common.

RED SPIDER (Tetranychus telarius L.)

South J. 0. Pepper (July 10): A few local infestations of the red
Carolina splder on cotton have been located in the Coastal Plains region.
The majority of infested spots are traced back to pokerieeds as
their origin.

Mississippi R. W. Harned (July 25): The first complaint of the year in re-
gard to the red spider on cotton received on July 11 from Cleve-
land. This complaint was accompanied by specimens. Cotton
plants infested nith this species were received from Holly
Springs on July 18 and on July 22 from Lula and Senatobia.

TOBACCO

TOBACCO FLEA BEETLE .(TPitrix parvula Fab.)

Tennessee A. C. Morgan (July 20): The tobacco flea beetles are more humer-
oue and injurious than usual in the vicinity of Clarksville.

TOMATO SUCKELY (Dicyphus minimus Uhler)

Florida F. S. Chamberlin (July 19): Two fields of bright tobacco in
Jackson County are very heavily infested with the tobacco suck-
fly. No other serious infestations have been observed.

SUGARCANE BEETLE (Euetheola ruaiceps Lec.)

Mississippi R. Harned. (June 22): Complaints accompanied by specimens of
the insect continue to be received at this office in regard to
the rough-headed corn stalk beetle or sugarcane beetle. Corn and
sugarcane are the crops that are being injured in most cases, al-
though in one or two instances cotton stalks have been attacked.
One man reported that 75 per cent of his sugarcane had been in-
jured by these beetles.

SUGARCAIE BORER (Diatraea saccharalis Fab.)

Louisiana T. E. Holloway and W. E. Haley (June 21): The third generation
of the sugarcane moth borer seems to be well started in the vi-
cinity of New Orleans and other points in southern Louisiana.
Hatched and parasitised eggs, work of the'first. instar on the
leaves, and larvae of the third instar in the stalks were found
on this date on sugarcane. This is at least a month early for
the third generation.


FOREST. AND SHADE-TREE INSECTS

MISCELLANEOUS FEEDERS

PERIODICAL CICADA (Tibicina septendecim L.)

Virginia W. J. Schoene (July 19): A fruit grower at Waynesboro informed
me that the infestation of locusts in 1927 extended from the
Valley to. the top of the ridge on the west side of the mountain,
whereas next year the locusts will appear on the east side of
the mountain. They have been reported from the following counties:
Augusta, Bedford, Botetourt,-Roanoke, Rockbridge, Rockingham,
Russell, Scott,.Washington, Wise, and Allegheny.

J. J. Davis (July 19): The tussock moth caterpillar was first
reported defoliating maple and other shade trees June 27. This
caterpillar is abundant throughout the northern two-thirds of
the State.

Illinois C. C. Compton (July 17): The white-marked tussock moth is more
abundant in northern Illinois than at any time during the past
six years. Observations indicate that parasites will check the
second brood.

Iowa C. N. Ainslie (July 21): After a partial disappearance for sev-
eral years this species is again ruiltiplying and is likely to do
severe injury by another season unless measures are employed for
the destruction of the egg masses this fall.

iHebrasia 1. H. S.enk (June 25-July 25): All over the eastern part of
;e'braska the white-marked tussock moth has developed a supernor-
mal abundance during the period covered by this report, and in
some localities the caterpillars have seriously injured the fo-
liage of the trees.

BAGWORM (Thyridopteryx ephemeraeformis Haw.)

Chio T. H. Parks (July 25): There have been more complaints than usual
of bagworm injury to fruit and shade-tree plantings. Complaints
come from southern and central counties. In one case the insect
had defoliated apple trees. Arborvitae was also attacked.

E. 7. :endenhall (July 9): The baagcrm is beginning to put in
its appearance in southwestern Ohio. I find it worse on ever-
greens and shade trees in towns and cities. (July 25): aor'-ay
maples and boxelder trees are being riddled by the bagworm in
different parts of Columbus.

Indiana J. J. Davis (July 19): The bagworm was reported damaging cedar
at Cynthiana July 2, soft maple at Princeton July 12, and soft
maple at Evansville, July 18.

several localities in Cumberland County (July 7).

TWIG GIRDLER (Cncideres cingulata Say)

Virginia F. E. Brooks (June 27): At Petersburg, where trig-girdlers have
been prevalent and destructive to hickory and persimmon for the
past ten years, relatively few twigs were girdled last fall. The
prolonged outbreak of this pest in parts of Virginia and the
Carolinas appeared to be declining.

BLACK CARPENTER ATT (Camoonotus herculeanus pennsylvanicus DeG.)

Ohio W. Mendenhall (July 4): Some of the old shade trees of his-
torical character of 1Torthington are infested with the black car-

A LEAF ROLLER (Gracilaria negundella Cham.)

Iowa C. N. Ainslie (July 21): This leaf roller is present in large
numbers on many bcxclder shade trees in the vicinity of Sioux City
this summer, doing little real injury, but spoiling the appearance
of the trees. Several species of parasites are busy just now and
promise a reduction in the number of the pest.

CHESTITUJT

A WEEVIL (Curculio auriger Cas.)

Maryland F. E. Brooks (June 6): Beetles of the lesser chestnut curculio
vwere found on the still unopened buds of the male catkins of
chestnut at Bell Station. Beetles rere not abundant; however, it
is probable that emergence from the ground was still under way.

ELM LEAF BELTLE (Galerucella luteola M'll.)

New York E. P. Felt (July 25): Grubs- of the elm leaf beetle were hatching
at Rochester June 23, but as there was noserious infestation, it
was not necessary to spray especially for this insect (R. E. Horse
Elms at Ballston Spa are showing some injury by this pest, althoug
in most.sections of the Hudson Valley there appears to be relative
little damage.

Ohio E. W. Hendenhall (July 19): The elm leaf beetle has put in its
appearance in !Fe Castle, -They have nearly all entered the ground
to pupate and .7ill emerge as adults in a short tie .

MAPLE

NORWAY MAPLE APHID (Periphyllus lyropictus Kess.)

New York E. P. Felt (July 25): The Norway maple aphid has been
abundant and injurious to Norway maples at Buffalo (M. H. Clark,
Jr.) and also at Rochester (R. E. Honsey). They are also found
in the .icinity of Albany and in the southern Hudson Valley.

Maryland P. D. Sanders (July 1): Specimens of the Norway maple aphid and
inquiries about itu control have been received from all parts of
the State during the past month. Parasites and predators are now
clearing up the infestation. The injury has resulted in leaf
dropping which is still continuing in spite of the infestation
decreasing, Many towns in all sections of Maryland have their
streets lined with maples which have been heavily infested this
year with the aphids. Automobiles parked for a few minutes under
a maple become splotched with honeydew. The aphid was reported
from Frederick, Snow Hill, Berlin, Salisbury, Chestertown,
Baltimore, Laurel, and elsewhere.

Indiana H. F. Dietz (June 28): The most conspicuous of plant lice is
the 'Norway maple plant louse which unquestionably is widespread
throughout the State wherever Norway maples occur, and has been
definitely recorded from the following locations, causing the
leaves to fall and the sidewalks to be covered with honeydew:
Indianapolis, Greenwood, Centerville, Martinsville, Richmond,
Greenfield, Rennville, Bluffton, Anderson, Marion, LaFayette,
Goodland, Remington, Elkhart, Rochester, Columbus, and Fralkl

J. J. Davis (July 19): Reports of the Norway maple aphid in-
creased materially the last few days in June and early July, be-
ing especially conspicuous because of the honeydew on the upper
leaf surfaces. Reports since last month's report came from Lake-
ton, Anderson, Nappanee, Summitville, Elkhart, Alexandria, Modoc,.
South Bend, and Winchester. The writer drove through from La
Fayette to ionroe, :iach., the last of June and in every ton the
presence of these aphids on hard and Norway maples was everywhere
evident by the honeydew. Likewise, there were almost as great in-
festations of other species on soft maple, boxelder, elm, and lin-
den.

Ohio E. W. Mendenhall (June 30): The Norway maples in the vicinity of
Columbus, also in southern Ohio, are covered with a sweet molasses
like substance which they excrete and the insects are causing th
foliage to fall.

FLAT-HEADED APPLE TREE BORER (Chrysobothris femorata Oliv.)

Indiana J. J. Davis (July 19): The flat headed borer was reported as ser-
iously damaging young maple trees at Hantirgton and Huron June
24 and July 13. respectively.

PINE

TIP :COTH (Rhyacionia bushnelli Busck)

ouisiana Monthly Letter of Bureau of Entomology, YTo. 157, May, 1927: On
Iiay 12 L. G. Bauthofer, stationed at Halsey, SNebr., arrived in Ashe-
Al.leIN.C.*to study the tip-moth situation about there, with a view
to obtaining new parasites to introduce in the plantations at
Halsey. Later, accompanied by ir. St. George, he left Asheville
for Bogalusa, La., rjhere the tip moth has been causing severe losser
for the past few years to the reproduction 6f young pine. Loblolly
pines were foun. to be the favorite host, while slash pine was but
slightly injured. Observations seemed to indicate that longleaf
pine was almost immune from this type of injury, its principal in-
jury seeming to be a loss in the attainment of height. Observations
were also made on a series of trap-tree studies that have been in
progress for the last two years, to determine the aggressiveness of
certain barkbeetles and the condition most favorable for their at-
tack and the development of their broods. On May 20 Messrs. Baun-
hofer and St. George conferred with .. D. Forbes, Director of the -
Southern Forest Experiment Station, New Orleans, La., on current
insect problems in the South. It was learned that tip-moth injury
has been noted in plantations all over the northern part of Louis-
iana, especially for the past two or three years, indicating that
this injury is cuite general in the State.

Maryland A. N. Caudell (July 14): A lady of Landover has for some six
weeks: ~Been troubled by the presence in her hair of the common hous
booklouse. It is stated that numbers have been combed from her
hairand specimens of the insects nere submitted to me for deter-

insects infesting the heads of persons.

A TICK (Dermacentor andersoni Stiles)

Arkansas H.. H. Schwardt (July 1): Several cases of tularaemia caused by
tick bites have been reported in Bento'n County during June and July
The mortality has been greater than is usually the case with tula-
raemia. Rabbits are not being hunted as before and as a result
are increasing rapidly.

A SPID(ER. cat pdectes mactans Fab.)

arkansas H. H. Schwardt (July 1): Two specimens have recently been found
in an orchard under de~ris, and a third in a corner of the in-
sectary at 'the Bentohville station. The last was in a large
tubular web which also contained an egg sack. Approximately 500
young hatched from the egg sack. This spider is reported by
Baerg as being one of the most poisonous in the United States.

.IOS1UIT0OES (Culicidae)

Louisiana T. V. King (July 23): An increase of the species Culex leprincei
has been coincident -ith the increase of Anopheles during the over-
flow in northeastern Louisiana. It is not troublesome in houses
as a rule, but has been very annoying out of doors at night and in
shaded places during the dfy.

-. V. Xing (July 23): Species of mosquitoes such as Aedes vexans
.eig. and Psorophora sai D. '& K. -ihich were numerous before the
overflow have not been at all in evidence since then.

MALARIA MOS&CUITO (Anopheles quadrimaculatus Say)

_ov si;ana UV. ing (July 23): A marked increase of this species occurred
during May and June in the area over.flowed by the Mississippi
Riveer in northeastern Louisiana, bedoming'a( serious pest problem
to people living in unscreened or poorly screened houses and among
the flood refugees in temp6rary cppes. There has not as yet been
a corresponding increase in the .iount of malaria, hbt with the
return of the refugees to their homes and with a continuance of










-249-

nopheles abundance this is to be expected before the end of the
season. Comparative counts of resting mosquitoes were egun
July 8 and the average number per house found underneath a group
of five tenant houses for three successive weeks was as follows:
July 8 1,100; July 15 991; July 22 929. The average for
two of these houses for which comparative recctds for previous
years are available were 977, 873, and 735 for the same dates ,hile
in July, 192,, the average was 145, and in July, 1924, only 22.
although the records for this year are above normal they were
nevertheless equalled several years ago as a result of excessive
rainfall during the spring and summer. However, from general ob-
servations made at Tallulah and elsewhere it was evident that the
increase of Anopheles has been greater in other places than at
-*ound. Thile the female Anopheles under norm;al conditions usually
do their biting after dark they have caused considerable annoy-
ance during this overflow by biting during the daytime in build-
ings or in shady places out of doors. The removal of most of the
domestic animals and the consequent lack of food for so many mos-
quitoes is a probable explanation for this change of habits. A
report from Bear Lake, where mosquitoes were said to be extrnmely
numerous, stated that Anopheles were biting out of doors in bright
sunlight, which is a decidedly unusual occurrence.



SCREW Pi0M (Cochliomvia macellaria Bab.)

Texas F. C. Bishopp (July 26): The screw worm has been extremely abund-
ant and injurious so far this year. The losses have been heaviest ir
the sojtheactrn part of the State, on the southern end of the Ed-
wards Plateau and southward. Many stockmen state that this is the
worst screw-.-orm year they have experienced. The death losses are
stated to range among sheep and goats from 1 to 5 per cent. The
death losses, naturally, have been heaviest among young stock. At
this date the flies are becoming less abundant, and apparently the
number of new cases is decreasing rapidly.

HORN FLY (Haematobia irritans L.)

Texas D. C; Parman (July 25): The horn fly has increased during the
last two weeks from 0 to 250 per animal to 100 to 2,500 per animal.

STABLE FLY (Stomoxys calcitrans L.)

Texas F. C. Bishopp (July 2): The stable fly is increasing to some
extent in northern Texas, but has not become sufficiently abund-
ant as yet to cause heavy losses. -Recent heavy rains since thresh-
ing has begun are probably the forerunner of much more serious
annoyance from these insects.

ROSE CHAFER (Macrodactylus subsoinosus Fab.)

Nebraska M. H. Swenk (June 25-July 25): During the last week if June the
rose chafer, as usual, appeared in abundance in the sandhill regio(

dreds of young chickens, turkeys, ducks, and geese were killed thi
year by eating these beetles. Two Custer County 4-H club boys re
ported that of a flock of turkeys, weighing about one pound each,

3al4nrnia Monthly NevwLetter, Los Angeles County Hort. Comm. (June 18):
Several reports have recently been received by the Los Angeles
County Horticultural Commissioner's office from -7idely separated
points in the county asking for information concerning a beetle
destroying furniture and woodwork. In one case the veneer cover-
ing of a dresser was found badly riddled by the borers. In another
the woodwork of an outlying post office was being seriously dam-
aged. In a third case the slide runner of an extension table ras
being damaged, and in still another the veneer paneling of one
entire side of a dining room had been ruined. An investigation
showed the work in each case to be that of one of the powder-post
beetles, Lyctus cavicollis, a small slender brownish beetle, which
mines the seasoned wood of oak, hickory, eucalyptus, etc., and is
recorded as common to California and Oregon.
