OUTSTANDING ENTOMOLOGICAL FEATURES FOR SEPTEMIBER, 1922


There is practically no change in the Hessian fly situation since
the last report. Observations in Iowa indicate that the heaviest
emergence in that State is taking place in the south-central counties.
The Bureau of Entomology Survey shows a decided decrease in the
percentage infestation in Maryland, Delaware, and southwestern
Pennsylvania, while in the Susquehanna Valley of the last State there
is a marked increase.

Favorable weather in the east-central States has resulted in a
decided increase in the number of chinch bugs of the second generation
to reach maturity. In all probability an unausal number of adults
will go into hibernation in this region.

The corn earworm was decidedly less serious throughout the northern
part of its range than was the case last year.

The true armyworm was not serious over most of its rang. In Illinois
it was less numerous than has been the case for many years. A few
isolated and unimportant outbreaks developed in the west-central States,

The apple and thorn skeletonizer continues to increase in intensity
of infastatioa and in its range in New York and Connecticut.

The shot-hole borer is attracting considerable attention in the
middle Atlantic and east-central States, where it is reported as attacking
apparently otherwise healthy trees.

The potato leafhopper associated with hopperburn has been very
serious in Wisconsin and western New York.

The Mexican bean beetle is consistently spreading northward; six
new counties in Tennessee and one in Kentucky are reported infested
during this month. Very little spread has been recorded southward from
the original Alabama infestation.

The belted cucumber beetle is rapidly becoming a major crop pest
in the lower Mississippi Valley.

The boll-weevil situation remains practically as in the last
report. Boll damage is now reported as serious in many places throughout
the cotton belt.

The bollworm is reported as serious in central Georgia, western
Arkansas, and several places in Louisiana.

The cotton worm continued heavy feeding during the month over the
Southern States. During the last week in September a serious outbreak
developed in eastern Virginia requiring control meaaur3s. By September
12 the adults had reached Urbana/, 1i. by September 21, they had reached
Bethlehem,. N.H.

The fall webworm is unusually abundant over the Atlantic Coast
States from Maine to Georgia and Alabama.

The birch leaf-skeletonizer is more seriously numerous than it has
been in years in New England, New York, Michigan, and Wisconsin.

P. R. Myers (September 20). "In the Southeastern Pennsylvania
area there has been a general decrease from 1).Ab per cent at
Na. !--'4h to 12.1.5 per cent at Wreri1.ile, except at ferkasic
whe-e there is recorded an inc -eoe of 4.68 p% cr In the

F. R. Myers (Sencember 20). "In the Delaware and Eastern Shore of
.!aryland area there has been a de.-tease in all lonalities e-xcept
at C=biridge, where there has been an increase of 1.09 per cent
an-1 at Princess Anne, where there has b&en an increase of 18.94
per cent."

W. P, Flint (September 18). "There is no change in the Hessian
fly situation since last month. A few flies are emerging but
eggs are very scarce in the central part of the State."

F. A. Fenton (September 19). "Three Hessien fly observation
stations have been established: No. 1 ae Spring Hills, in warren
County: No. 2 at Or:a5ia, in Toi)rona Co-inty; and No, 3 at Essex in
Pago County. Judging from reports Dtern- in f-'om these stations
infestation sees ,0o be rost severe in the iri:.rty of "arren
anr Polk Counties. At the "aiiei County staiio thIe fly has boen
emerging more abundantly thar. at e_.th" r of ,hh other st.tiona and
there is a compara+;..ely sn3J.l pe-rcanbe of parofitism at this
station as compared w-.th a h.gh pfc-'?.age at th, ?Pge ared :'oiona
County stations. At this tir in i1-,1 -ho majority of the wheat
was planted in warren and Polk Count..-s. 0w'ng to the campaign
put on this year, at the present .re there are only four fields
sown in Warren and one in Polk County."

JOINT "OI (aI~_ol'Jta tritici Fitch)

7. P. Flint (September IS). "Paasites of the jointwom are very
abundant. Con+.s show approximately 50 per cent of the larvae
killed in this way. survey conducted during August showed a
spotted infestation ranging from 2 per cent to 46 per cent in the
southern part of the State."


CORN


CHINCH BUG (Bjiesus. leueopterus Say)
J. J. Davis (September 19). "Now that the wheat-sowing period is
approaching, farmers are finding plenty of chinch bugs in cornfields
and are inquiring as to the advisibility of sowing wheat in the
infested fields."

W. P. Flint (September 18). '"7eathor during August and the first
of September was very faxo-able for the development of the seco.id
brood of the chinch hug. t' ty pe- cent or more of the Lu-s are
now adults and it se-rs cex'tain that much large- nunters are going
into hibernation than was the case in the fall of 1921. Sec-eniy-
five per cent of the Counties in Illinois are now infected. Heaviest
infestation occurs in the west-central part of the State."

M. H. Swenk (Atigust, 1922). "The chinch bug has not proved as
injurious in northeastern Nebraska as had been expected.'

J. W. McColloch (August 23). "The chinch bug occurred in damaging
numbers throughout the eastern he.lf of the State. Some bugs were
found as far west as Thomas County."

COBN EARfVOBY (1 eliothjs oSzoleta Fab.)

B. G. Southwick (September 19). "Rther numerous in Hartford
County, though not as bad as last year. A few larvae were observed
in Hamden Qnd New Haven by Dr. Britton and I'r. Zappe."

H. C. -Dell. "The corn earworm has been commonly observed in the
plantings of sweet corn in Nassau County since the middle of August."'

E. P. Felt (September 23). "The corn ear'wor- was reported from
several localities in the lower Hudson Valley and on Long Island.
The damage in 1921, however, was much more severe than this year."

C. 0. Houghton (September ll). "This species is much less abundant
than last year in sweet corn about Newark, yet there is considerable
infestation in some cases."

W. P. Flint (September 18). "This insect has been much scarcer than
at any time during the past ten years. Tha infestation in ,sweet
corn in central Illinois was carefully followed throughout the
season and never ran over 3 or 3-- per cent, averaging about 2 per
cent. Uloths are now appearing in greater numbers but too late to
cause any damage to field corn."

S. B. Fracker (September 15). "The outbreak of 1921 was not repeated
this year. A single report of a few early-season individuals was
received from Oshkosh."

I. U. Hawley (September 2). "This insect has become a serious pest
wherever corn is grown. As high as 50 per cent of the ears are
iinfested in some places."

J. J. Davis (September 19). "'On Septpober J6 the county agent at
Rockford in the ecuth;e?,i corner of the State sen'c s:,opirens of
the ?OmL2.OA a. m v w:-;h t.h. information that they were abundant
and cam.gi;/g corn in one locality."

W. P. Flint (September 18). "Bait traps have been run for several
seasons and this year have given the sn.al.e3et catch of adults of
this species."

S. B. Fracker. "A single outbreak of this insect has core to our
notice this year, this being in St Croix County, but caused no
serious injury."

M. H. Swenk (September 1). "The true arryworm appeared in the
fields of millet and corn during the second weel: of August and did
considerable injury in places. In Antelope County, in particular,
there were several aileis moving and destroying crops at that time."

WHPAT"HEAD ABRITOpM (lTJ'.vi-al-. ',Linra Huebn.)

I. H. Swenk (September 1). .a-r, fi County, at the same tie
that the true armywozm was active inr. the seoAd wek in : iLixt,
some of the oat fields were overrun with ihe wheat-head armyworm
which ate the heads of the grain."


WHITE GRUBS (Phyllophaga spp.)


Illinois


WV. P. Flint (September 18). "A number of fields of corn in east-
central Illinois ha;i'e been quite severely damaged by white grubs.
In most of these fields areas of two or th- ?e acres will be injured
but the rest of the field very lightly in'ested. Most of these
fields were in corn in 1921, the grubs being now in their second
year of development."


A FLO"TR--BFETLE (_,nlor-a .,.,c ,-alis Fab.)


Indiana


J. J. Davis (September 19). "This flow3--beetle was reported from
Evansville on September 12 as do.'ng considerable d-ma,7e to corn by
feeding on the maturing kernels."


ALF ILIA

ALFALFA E.VIL (Phytonomus osticus Gyll.)


California


(California Weekly News Letter, August 26.). "The alfalfa weevil
has again been intercepted in automobile camping equipment, this
time at Truekee. The weevil was taken on August 26 on a machine
from Nevada."


CC0PEA

COWPEA CURCULIO (Chalcodermus aeneus Bob.)


Georgia


0. I. Snapp (August 23). "Complaints are reaching the laboratory
from various sections of central Georgia relative to damage to cow-
peas by this insect, which does considerable doarage each season."



















Wisconsin





Nebraska










Kansas


F. H. Chittenden (September 8). "Mr. H. B. Lancaster reports that
the cowpea-pod curculio was injurious to mung beans at Thomasville
during A:i[,uot."

GET 'FRAL 717FF7F?

GRASSHOPPERS (Acridiidae)

S. B. Fracker (August 15). "The infestation in the northeastern
counties, extending from Door County to iron County and westward
to Price and Lincoln Counties, has been fairly well controlled by
general distribution of poisoned-bran through town-board organiza-
tions. Egg laying was quite general after July 15."

M. H. Swenk (September 1). "Grasshoppers continued to be numerous
ant.. injurious in Scotts Bluff, Morrill, Sheridan, and Sioux Counties
and thp local outbreak in Washington County, which was in-irestigated
carefully during the third week in August, proved to involve a
conCirrable reduction in the alfalfa yield. The species generally
cone ern3d in northwestern Nebraska is 'elarnplujs bivijtJt'iJ. Say,

J. W. .cColloch (August 28). "ela1nornlus difforenti'lis Thos. and
M_. _biitJ-.- v ay are the predominating spec ies in an outbreak in
the :arc, .. te'n part of the State covering Thomas, Sheridan, Graham,

insect."

COTTOINY MAPLE SCALE (Pulvinaria. vitis L.)

E.J-Newcomer (August 7). "A several infestation of this scale
was found on a small block of "'inter ielii. pear t.ru., the
leaves being covered with honeydw.. An application of nicotine










sulphate 1-1,000 and soap appears to have killed a large percentage
of the young. An interesting feature of this infestation is that
Bartlett paar trees adjoining the Winter i2Jli: have no adults
and only a light scattering of young on them, the scale evidently
preferring the 7Tinter Nelia variety."

PEACH

PEACH BORER (Aeg.ria exitiosa Say)

Georgia O.I.Snapp (August 7). "At least 95 per cent of the peach growers
in the peach belt of Gaorgta will use para-dichlorobenzene for
this insect. There will be bweween three hundred thousand and
four hundred thousand pounds df this material used in this State
this year."

PLUM CURCULIO (Conotrachelus nenuphar Hbst-)

Georgia 0-I.Snapp (September ii). "The curculio damage to pe-icheo in the
Cornelia or northeastern Georgia district was greater than in
central Georgia this year. The infestation was heavier there
than it has been for the past several years and is readily
accounted for by the failure of the growers in that section to
use the full amount of arsenate of lead in the important last
application for the second generation, and also to the prevalent
rainy season. This district is not in the peach belt of central
Georgia. At Fort Valley adults of the second generation were
emerging during the l-tst few days of July and the first week
in August. Jarring of orchards during the first week in August
gave less than 1 beetle per tree. The jarrings a year ago
gave an average of over 5 beetles per tree. This is largely
due to effective control measures practised during the past year.
Third-generation eggs were taken on the morning of August 17.
This is perhaps the first record of a partial third generation
in this latitude. On August 22 larvae of this generation were
noted in the insectary entering the fruit; on September 11, a
full-grown curculio larva, of the third generation left the fruit
in the insectary. This larva immediately took to the soil and
started to prepare for pupation- A number of adults of the
third generation will in all probability be bred out before the
close of the season."

Conotrachelus anagll ticus Say

Georgia 0-I.Snapp. "This insect whose life history is very similar
to that of C. nenuphar has been bred from peaches that fell
to the ground during June. In all probability this species
frequently attack ..peaches in Georgia and all of the damage
heretofore has been attributed to the latter species- Frequ.3ntly
the adults of anaglypticus have been taken from the frames while
Jarring for C& nenuphar."

S. W. Frost (September 15). "The fruit-tree barkbeetle is
abundant in some orchards and has been found on living peach
trees. On September 6, adults were issuing in great abundance
from the limos of peach trees."

0. I. Snapp (September 12). "This insect is doing considerable
damage and is numerous in peach orchards, where the trees have
become unhealthy from severe San Jose scale infestation. The San
Jose scale is on the increase in central Georgia peach orchards,
which accounts for a greater abundance of the barkbeetle."

J. J. Davis (September 15). "The shot-hole borer continues to be
the subject of frequent inquiries."

W. P. Flint (September 18). "Damage by this insect has been quite
general and in some cases the trees attacked have apparently been
in good condition, but have been somewhat weakened by prolonged
drought. Spring applications of nitrate of soda have saved many
trees in which the injury was not too groat."

Calopteron reticulatum Fab. and C. terminal Say

M. H. Swenk. "During the last week in August an unusual report
was received from Franklin County to the effect that these
lampyrid beetles were destroying peaches by eating into the fruit
just es they were beginning to turn."

PLJ_

PLUM CURCULIO (Conot'achelus nenuphar Hbst.)

R. A. Van Meter (Septemoer 13). "In the Hill sections of the
State, especially, this insect is very serious on apples. It
is worse than the codling moth."

S. B. Fracker (September 15). "This insect is unusually abundant
in the southern counties this season. It is also extremely
difficult to control."

0. I. Snapp (September 12). "The fall webworm is much more

pecans, persimmons, wild cherry and sassafras, and several
nests have been found on peach with the larvae feeding on
peach foliage."

the infestation increased to from 20 to 25 per cent in many
cars. Some fields showed easily 50 per cent of the potatoes
affected. The total number of cars inspected was 578. Of
these 213 were found to be infested. The estimated less was
between 15 and 20 per cent of the crop. These figures are
from the reportss of Mr. H.H. Warner, district supervisang

W.E.Hinds (September 21).- "The Mexican bean beetle cleaned up t1e
table beans of all kinds in the areas becoming generally infested.
in the fall of 1921 so that practically no green bean vines
have existed since the middle of July. The spread of the species
southward appears to have been light and no complaints have been
received beyond the lines reached by the beetle a year ago.
The influence of the prevailing direction of light breezed., which
come from the south, explains, we believe, the slow spread in
that direction."

WpE.Hinds (September 21). "Boll-weevil injury has been much less
during the present season than the May prospect indicated, largely
because of the control exerted through the unusually dry hot
weather continuing quite generally through the State in June,
July, and August. During June the rainfall was less than one-third
normal and this checked the weevil to the extent that the cotton
has fruited unusually, in the southern two-thirds of the State,
particularly. Rainfall for the 3 months has been only one-half the

E. E. Hollister (September). "This insect was first fund in
Hartford County by the gray cclor of the ground underneath the
trees ,vhich vas caused by some discharge from the aphid. Only
some of the lower branches seeirm tc r.-e insects on them. This
outbreak is much worse than usu-nl in this reason."

J. A. Hyslop (September 5). "This aphid is much more abundant than
it has been during the rast three or four years in southeastern
Montgo-nery County, The insects completely cover many of the lower
branches, giving the branch the apFpearance of being covered with a
cottony quivering vesture, Sometimes branches up to 1 inch thick
are corrletely covered for several feet. These aphids are so
numerous that under some of the trees the ground is discolored by a
blue sooty mold growing in the honeydew, and on the trunks of the
trees larga masses of a yellow fungus having the texture of sphagnum
moss are zroiing in the same honeydew."


BIPCH LvFk-SIFLETO'TIZErP (Bucculatrix canadensisella Cha.b.)

Massachusetts H. T. Fernald (September 21). "The '-ite birth has been attacked
by the birch Bucculatrix practically over the entire State. From
Boston Nest to beyond Worcester, even tiny birches not Tore than a
foot high have been completely skeletonized, and the birch trees
look as though fire had runn thr-uz'h them. This condition is also
present throughout the Connecticut Valley, though here and there
areas of only partial skeletonizing appear. I have not been able
to ascertain whether or not this insect is present in the Berkshires."

New Hampshire H. T. Femrnald (September 21). "On a trip last week up through the
Thite Mountains, there vere evidences of its work up the Connecticut
River to Wells Junction and through the .Thite mountains here and
there, but it seemed to be less in evidence around Lake WJinneresaukee.
Around Concord it was also noticeable, and across the southern end
of the State to Keene, on the vest. On the whole, hc:;ever, I should
hardly consider the Ne T Ham.pshire defoliation as severe as that in
eastern Massachusetts, where it is the worst I have ever seen it."

abundant on birches, especially in the northern portion of the
State and particularly in the Adirondacks. Considerable areas in
this latter section and adjacent thereto have been so thoroughly
skeletonized that practically all the leaves dried and dropped.
The injury was not so severe in the vicinity of Altany as in 1921.
