I S ECT PES T SURVEY BULLETIN


Vol. 4 September 1, 1924 ::.. 6


O, T3TT I::G ::T:::...GCAL FAI-. T I:D Si.... FOR AUGUST, 124

In this number of the Survey Bulletin is a svumary of the Hossian fly summcr
survey from New York State. This indicates a general reduction of infestation
throughout the wheat 7ro-ing section of the State, fh-j infe station in, 1923 avrra-.
ing 8.5 per cent, while this year it av.ra:.es but 6.4 pc'r cent. In Ohio the inf ss-
tation has incrL:-aed in the northeastern counties, in some cases running as high as
24 per cent. Indications of rather serious fly conditions are-also reported from
Indiana, Illinois,' ':jrth Dakota and Kansas.

The chinch bug situation remains about the same as last month h throu-h Lut the
greater part of the chinch bug belt.

The corn earworm is agin appearing in -. : ,-r". T':r last outbreiak in this
region occurred two years ago.

The, fall armyvor,. has alr-_?.- appeared in Kentuc'-" and is doing considerable
damage. This early appearance m*-.iy be the fore-runner of a. more general outbreak
later in the se-ason.

The wc.stern corn rootworm is reported as seriously infesting corn in Missouri
and Kansas. The beetles are now cutting the sir.,.

.The Conchuela (Chloro chrc lj- atr' S:y) is reported as doing immense -.. J .: to
the seed crop of alfalfa in the Fort Stockton and Fecos sections of Tc:-as.

Late in July and early in August the gro..n apple aphid was reported as becoming
seriously abundant throughout the apple-rowing section of i .; York State.

The variety of the coiling moth lmo'T as CarIDom omonella si"rsonii usk
was rdared for the first time in the Ya.ki-a re-_ion of -.;.:".gton State. Side Iorm
injury by the codling moth is reported as mor- seri-us than usual in -__. EnThland
and east.:-n ITew. York, .while in western Tew Yohk the damage is not as serious as
last year.

The saple and thorn skeletonizor is now- generally distributed in !Tcw En, land
and 7w York State. In 1Massachusectts it ras serious enough to occasion a special
j.-ray; .in 7,' York State, as a -"h-le, the insect was less serious tian us-ual.

The 7..-nted lady butterfly was report, during the last weCk in July and the
first v4eck in August in unusual n-umbers in wisconsin and South D'rkoita. 7his is
practicallr, the termination of the unusual development of this insect throughout
the entire western and central United States, anr Mexico.

During the past month the potato lcafhopo1r has be, n rapidly incra-singE in
I,.li:-,_. Sm-c fields, in the west-central part of tihe State, have b_,,n killed.

The i,-xican bean beetle by August 25 had extended its range eastward in Virgin,
to Craig and Carroll Counties, being now nearly half way across the State. In Wesi
Virginia it has advanced from the southwestern border of the State eastward to Mar-
shall, Tyler, and Wetzel Counties, covering about three-quarters of the State. In
Indiana it is only found along the southeastern border of the State in Floyd, Clark,
and Jefferson Counties. In Kentucky it extends over practically the entire eastern
two-thirds of the State. In Ohio about the southern three-quarters of the State i?
infested, infestations ranging as far west as the southwestern corner of the State
in Butler and :'Ii-lton Counties, and northward to Hancock, 7ayne, and Tuscarawas
Counties. It hars just invaded southwestern Pennsylvania, being found in Washingtor
and Green Counties.

The cotton leaf-orm during the third week in August appeared at several points
in Arkansas, and 1-'dicon Parish, La., while during the second week of the month it
was reported from Alrb'nsa. The insect seems to be unusually abundant in Arkansas.

The boll weevil as a whole does not seem to be as destructive as during 1923.
The boll worm, on the other hand, is reported as generally more destructive in
California and Georgia.

In this number of the Bulletin is published a summary of the past ten years,
observations on the abundance of the sugar cane borer in Louisiana.

Bagwvorm is reported as generally on the increase in western Missouri and east-
ern Kansas, and is also reported as doing damage in parts of Ohio. In. the Ohio
River Basin the catalpa sphinx is causing considerable trouble.

The elm leaf-beetle is worse than it has been for several years in western
Connecticut and southeastern New York. It is also reported from Michigan, and 3
reported for the first time from the State of California, where it has appeared in
the Fresno district.


OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA FOR AUGUST, 1924

The grasshopper situation in the Nicola Valley, B. C., where there is an out-
break of the roadside grasshopper, Camnula pellucida Scudder, and the lesser migra-
tory grasshopper, Melanoplus atlanis Riley, is expected to assume more serious pro-
portions in 1925. In the Thompson River Valley, 3. C., from Kamloops to Chase,
there is a very heavy infestation of Melanoulus atlanis Riley.

Grasshoppers are causing little trouble in ..:anitoba and southern Alberta this
year.

The eye-spotted bud-moth, Spilonota ocellana D. & S., and the green bud moth,
Argiyroploce variegana Hbn., have been abundant to an unusual degree in the Annapolis
Valley, N. S.

.The fall cankerworm is gradually increasing in numbers throughout the Annapolif
Valley, N. S., and another outbreak is about due.





- 211 -


The spruce sawfly, Diprion abietis Harris, is unusually prevalent in southern
MTanitoba.

The larch sawfly, LyMconematus erichsoni Eartig, has caused serious damage
throughout wide areas in New Brunswick.

Green fruit -vorms of different species have been more abundant in the Annapolis
%lley, T. S., this season than for several years previously, and considerable dam-
age to fruit has resulted.

Injury by blister beetles has been reported from nearly all parts of i'nitoba,
the plants chiefly affected being Car-ga;:' hedges, potatoes, beans and peas.

The green apple bug, Lveus conmunis Knight, has been gradually increasing in
numbers in the Annapolis Valley, N. S., since 1919, when it was subject to an epi-
demic of disease. The increase has been most marked during the past year.

The rose, curculio, Jvnchieitos bicolor Fab., has been very injurious to roses
throughout :.lnitoba during the early su=cer, f-lly half the blossoms being destroyed
by them.

The false chinch bug, ::esr- ericae Schill, became a very serious pest in the
drier sections of Mb--rta di.. July. injury being done to wheat, radishes, cabba _
raspberries, strawberries and ve xou fe:e..

Geo. F. Knowlton (July 31): Grasshoprers are not as severe in thi
State as at this date a year ago. A f-w sections are having to us
poison bait.

THITE C-7.U S (Z-? -' ha-a spp.)

W. P. Flint (August 26): Reports of white grub der-rae have been
received from many of the central and no-rti n counties. i.uch
damage was reported where corn has followed corn. Apparently the
eggs were in many cases laid in corn ground during 1923.

M. H. Swenk (July 10-August 1): Next to the chinch bug, the most
complained-of insect pest during the period covered by this report
has been white grubs. The reports tell of damage to bluegrass
lawns, strawberry patches and flower gardens. Practically the
whole of the eastern half of the State is more or less affected,
owing to an abundance of -':iy beetles flying in the spring of 1923,
but the most serious reports have been received from Knox, Garfield,
Lancaster, Clay, and Furnas Counties.

Geo. F. Knowlton (August 8): WThite grubs are doing considerable
damage in some sugar beet fields in Cache County. All beets were
killed in some sections of certain fields in Benson Ward.

A BEETLE (Ochrosidia (Cyclocephala) sp.)

W. P. Flint (August 26): Adults appeared in large numbers about
lights during the first part of August. At single sTreet lights
from 600 to as high as 1,000 beetles were observed by act-cal count.
The flight continued from July 26 to August 4. A fe-7 beetles were
observed about lights up to August 22. No feeding by the adults
was seen, although large trees projected close bo street lights.
The flight seemed to be confined to east-central Illinois.

H. F. Wilson (August 5): Wireworms were also bad, but we did not
get a determination as to the species.

C. R. Crosby: The Hessian fly survey for the current year covered
16 counties, 8 more thin were covered last year. The av'r?.e in-
festation for th3 ri1on covered last year was 8.5 per cent. This
year the scne region nah an infestation of 6.3 per cent, b-hile the
avrrgte infestation f+'or the 16 counties where counts "'-:ri made
ac,.'.td to ,5.9 per cent, showing a decided decrease in infestation.

T. H. Park:s (July 38): Hessian fly infestation in Ohio has increas-
ed from 4_- to I- per cent (infestation of straws) in 31 counties
e::-,i--..:, infestatiops of 15 to 2;4 pcr cent exist in northeastern
Ohio counties. s .-'rthnestern counties now have the least fly in-
festation in the State.

C. R. Cleveland (August 18): Conditions thus far indicate energcnc
of flies on approximately normal dates. Observations continue to
indicate a great be.n'.m1-nce in early-sown fields this fall.

'T7. P. Flint (August 26): A state-wide survey covering 34 of the
largest wheat-growing counties in the State has shovn a state avrae
of 2.3 living fly per single foot of drill row, and the same average
for joint 7o0m. The highest average number of fly per foot of dri!i
ro7 occurs in the northeastern part of the State. In Bureau County
4.7 living fly per foot of drill rozw -as found. Fly is less abundd-
ant in the southern hilf of the State, the lowest county showing .2
of living fly per foot of drill row. D'.'-iopment of fly for the
season aIpo':'s to ae about nomwal, apparently there vrill be no suppl-
mentary falI tfr"... of f-ly t'_..s ycar; fly was present in every cointy
in vhich this surve-,y wa conuc tdc, and in 262 out of 291 fields
exz-n i.itd.

CH.INCH BUG (lissus leuccpters Say)


Illinois





South Dakota



Nebraska





















Kansas





Texas




Massachusetts


7. Flirt (Au ust 26): Heavy rains during the latter part of
July and the first of August have reduced this insect to a point
where ractically no i:r-.'y to corn will occur in Illinois during
the p ir>ent season. 1Theroe sre less bugs at this time than at any
time since the sumn=er of 1911.

H. C. Severin (July 20): This pest has become a negligible factor
in this State except in isolated places here and there in Charles
IMix, Ben Hor.ue, and Douglas Counties.

T. H. S7w2k (July 10-August 1): By far the .-t injurious insect
during the period covered by this repor; has been thec. hch .Li ,u.
Tie migr'ion rom the wheat and barley fields into the corn, be-
ginning from June 25 to July 7, continu-3d until about the middle
cf July, when it was practically over. The bugs '-- re .ig rating
heavily all th-ou.l the i feste uare-a from July 10 to 15. T'he
infe '! d area continued L o Le as oulined in 'y last report of
Jul.ly1, .cept that the .,s anc. Ctcrar Con ty infs t -1 ions
proved to eed est to -;tern Phe].Js County and northeast
even to southwestern 3nfalo Cointy, in the vicinity of Elm Creek.
The infestation in southern (not northern, as stated in error in
my report of July 10) Siline County proved to be serious in the
vicinity of Vestern. As thus revised the infested area includes
Richardson, -W.r.h, Pawnee, Johnson, southwestern Otoe, southeastern
Lancaster, Gage, Jefferson, southern Saline, Thayer, TIuckolls, 7eb-
ster--, ----:ln, Harlan, -urnas, Gosper, '"--tern Phelps, and south-
western *-ffalo Counties. Complaint of injury has ceased at the
time of p:rtp ring this report. No serious chinch bug outbreak
has as yet developed in northeastern Nebraska, where the pest was
injurious last year, only a few reports of an abundance of the pest
having been received, and these all from Knox County.

J. W. IIcColloch (August 13): Chinch bugs are abundant in the corn
and sorghum fields, although there are few reports of serious damage.
A farmer at Lenora reports the loss of 25 acres of milo. Plenty cf
rain during the last month has been favorable for the development of
the fungus.

F. L. T,) (August 12): IT:,.,phs and adults very abundant upon
agronomy test plat to whircl the insects had migrated from corn.

COKT EART'O:" (Heliothis obsolete Fab.)

A. I. Bourne (August 20): On August 4 and the succeeding few days
we had complaints of the corn earworm on sweet corn. These were
the first complaints received since the outbreak of two years ago.
Specimens sent in varied considerably in extent of development, but
were approximately one-third to one-half grown. One or two fields
in this immediate vicinity were reported to be quite heavily attacke(C.
As yet, however, we have had no complaints from other points in the
State.

F. S. Chamberlin (August 21): Several fields of running beans nea-
Ouincy are e'ing seriously damaged by corn earworm larvae, which
confine their attacks mainly to the pods. Field corn at this time
is hairdening and is unsuitable as food for this pest.

STAILK RP (P.apaipema nebris nitela Guen.)

A. I. Bourne (August 20): W7e have been finding from every lot of
material of Farwriocma nitela which has been collected in this iLnme-
diate vicinity, or has been sent in to us from other parts of the
State, that the larvae are parasitized apparently to an unusually
large percentage.

I.L H. Swenk (July 10-August 1): The stalk borer continued to be
reported as injurious from July 10 to 21. In a few cornfields the
injury was serious. Two Cass County fields near the Otoe County
line ';ere thinned out cuite perceptibly, a couple of fields in -ash-
inton County were badly injured, and a Hamilton County cornfield
was also thinned out quite seriously through the activities of this
pest. Other reports were of injury to tomato plants and flowers.

APRM'JO.M (Cjphis unimjneta Haw.)

F. S. Chamberlin (.Au, ,ist 2): A slight infestation of armyworms
was observed upon bear. foliage on August 2.

H. F. Tilson (August; 5): e .iave had a serious outbreak of army-
-orms in the southern part of the State.

FALL AIYTTOFL: (Laphyna fr1inerda S. & A.)

H. Garman (August 23): Fall armyworm has already appeared in Ken-
tuc2.y and is doing excep-otional injury to corn in Christian County.
I have had a number of specimens sent to me recently by a corres-
pondent -ho is very anxious about checking the mischief. This
insect generally appears here late in the season and only occasion-
ally attracts attention because of serious mischief. Generally
it works on rye and other plants of the same family.

H. '7. Alen (August 23): T-o heavy infestations of the southern
grass worm have appeared at A. & M. Collce within the past week.
In one, -.n meadow of Johnson grass of about 40 acres, the defoliation
ranges from severe to complete. The worms are now beginning to
develop the armyw-orm habit. i'No damage to corn has as yet been
noted.

CORIT-LEAF APHIID (Aphis maidis Fitch)


Mississippi


Indiana








Illinois


Missouri




Kansas


H. T. Allen (August 19): The corn-leaf aphid is now abundant in
the tassel end of Late corn, apparently increasing to a considerable
degree the stm-ngn resulting from long continued dry weather.

.T=ELV-SFC:oP:B CccLB'_-PET:E (Diabrotica 12-punctata Fab.)

C. R. Cleveland (August 18): Specimens of well-grown corn with
nearly full- grown larvae of this species were received from Frank-
fort and Fowler the second week in August, with the statement that
many plants were dying. Injury by the wor-iA, however, while ap-
parent, would not seem to have been severe enough to cause the
death of the plants. A combination of this injury with several
weeks of extremely dry, hot weather was possibly the cause of the
severe injury.

47. P. Flint (August 26): Damage by this insect has been very severe
and much more ',rier:U than usual. In some fields 90 per cent of
the corn showed fallen stalks where counts were taken. In a num-
ber of fields in the central part of the State this insect will cut
the yield from 5 to in exceptional cases as much as 50 per cent.

WESTF:JT CORN FQ01,T02M (Diabrotica lonzicornis Say)
T
L. Baseman (July 28): 'Woims vary from one-half to full gro'-n.
They are werse than in an average year. Ti-hole fields damaged
seriously. (August 22): This worm is causing quite a bit of
trouble in some sections of the country.

J. W. 'cColloch (August 16): The adults are reported very abund-
ant in cornfields about Irving. They are cutting off the silks,
thus preventing fertilization. Several fields show the work of
the lar-ae earlier in the season. All cases of larval injury are
in fields which have been in corn for several :,.yrs.

P-ATJE-S"2PIPED FL2A-B7ETIZ (Systena taeniata var. blanda Melsh. )

H. F. Wilson (August 5): This flea-beetle caused a great deal of
da:mage to the r,' jtts of corn early in the season. Corn planted in
fields which were last year in weeds suffered serious damage. A
nrumLer of lar:vae were found feeding on the roots of corn, and from
these ve wrere able to breed the adult flea-beetle.


A:TIG-LLATED FROGHCPPER (Lepyronia guadrangularis Say)


Arkansas


7. J. Baerg (August 4): Lepyronia quadrangularis is causing appre-
ciable injury to corn in Carroll County over an area of several
acres. The spittle insects were found in aggregations of 20 to
50 on the undersides of the leaves, in the axils and on the tassels;
on a single plant, in some instances, there were more than 100 in-
sects. Tre corn is located near a field of timothy that had been
cut about two weeks ago. From here the spittle insects migrated
into the corn.


ALFALFA AND CLOVER


GFDIFI: I?7OPCB (Loxostege similalis Guen.)

I.. H. Swenk (July 10-A-ugast 1): A local outbreak of the second
brood of the alfalfa or garden rweborm occurred in Lichi-rdson Count3
in the vicinity of Dawson about the middle of July.


ALFALFA ^r..A.TODZ (Tylenchus dipsaci Kuhn)

C. R. Crosby and assistants: Side-'-orm injury ras not as prevalent

APPLE ATD THC'FU S}:TL:ET*CPuPI (Hemerophila r-ri-n, Clerck)

A. I. Bourne (August 20): During the week of August 4 the second
brood larvae of the apple and thorn skeletonizex were advancing
pretty well toward maturity here in the Connecticut Valley. Un-
sprayed and. uncared-for trees were browned up nearly as badly as
last year. By the succeeding week (August 11) numerous cocoons
of this brood were being found. It is apparently working into
sprayed orchards more than it did last year. Here at the college
it was rnm.aling its appearance at the time of the second brood in
numbers enough to cause serious injury, and appeared to be particu-
larly severe on our blocks of Wealthies. A special spray, applied
Auoyst 11, checked the pest.
In the western part of Hampshire County the skeletonizer is not
particularly ab-.uv-i1- t.
This pest has made its first appearance this year in Bristol
County, where new- gro-cth was very badly riddled on many trees,
especially in orchards hiich were not thoroughly sprayed.

A. E. Stene (August 22): I can report that the apple and thorn
skeletonizer, of which we found the first moths in the State a year
ago -last spring, and which was sent in by fruit grcrw-rs for the
first time about August 1, 1923, is a-pparently widely distributed
over the State, although no very striking injury has as yet been
caused by the pest.

A. I. Bourne (August 20): Unlihe last ,-ir the European red mite
is not shoving up to any serious extent in our college orchards or
those immediately around here, nor have I seen any orchard which
shows serious bronzing an:y.here in the vicinity of Amherst.
ir. Gculd, cf Tilliamsbuarg in the western rart of Hzampshire County
reports that this insect has not made its appearance in any serious

increasing in abundance in this county.

is present an! can be found in slight numbers in almost every orchi'r
but ouing to the quite general practice last season of using miscibl
oils when the leaves were donna the pest -as apparently so well con-
trolled that it has not become as abundant as last year.
In Middlesex County :l-. Dayton reports that red mite is quite plen
tiful, and in a fe- orchards the damage has attained considerable
proportions.

Philip G-rmaen (August 23): Still very scarce as compared -ith last
:year. Hardly any can be found at ZTe7 Haven.

B. A. Porter (Auust 23): Moderate injuir:: is apparent in occasion'
peach and apple orchards throug-i southwestern Indiana.

E. J. Nercomer (J-'ly 31): MThe European red mite continues to be
more numerous than usual on apples, pears, and prunes. Many grow-
ers are getting excellent results ,Aith 7eak oil sprays in controll-
ing it. lNe-ly-hatchd individuals of the fifth brood '7ere found
July 6 nearly four weeks earlier than in 1923. (August 23): Pre-
dators have increased rapidly since August 1, and in many orchards
where the mites have been numerous they are no7 hard to find. These
predaceous enemies include Scolothrips sexracitlatus, a small black
ladybird (Stethorus punctum), one or tro species of predaceous mites
(Seius sp.), and a predaceous bug (T iehfMtps insidiosus). The

past few days many recent eg, and feeding punctures have been ob-
served on ripening fruit an. very tiny larvae were found in several
peaches that were closely examined. These observations seem to

OIi':: -,f FRUIT MOTH (Laspeyresia molesta Busck)

Georgia J. D. Gill (July 24): The occurrence of the oriental peach moth

insect appears to be more abund-r.t in the city limits of Thomasville
than in the rural districts immediately adjacent to town. At this
-riting nearly full groan larvae are found in ripened poaches collect
ed from the ground. The excessive dropping of peaches from seed-
ling trees in this section seems to have been caused by the combined
attack of the curculio and bro-r.-rot rather than from the f-eding of
larvae of the oriental p-:ich moth. Larvae have been observed pupat-
ing on the bark of trunks and larger limbs of peach trees, as well

revealed the fact that sqouashes were groi between these Tgreen-
houses last season, which would at least account for the presence
of the bugs in this irnmiediate vicinity. Many of these matured
either in or around the r---- :,-io-uses and later transferred their

BOLL i"='357..L (Anthonomuns :raidis Boh.)

General B. PR. Coad (August 25): The weevil season of 1924 which is
row dawg to a close has been a most peculiar one. Emergence
over the cottc:n belt as a whole was 7ci'-raily rather -l.'it,
w;-.,th the exception possibly of some extreme southerly points
such as the G-.J.f Coaot of Texas. In most of the territory,
ho:.'ever, the initil emergence ranged, fi-'om 1/5 to 1/10 of that
of 3ast ycar-. For this reason wev;.i:s were quite generally
not abunidant enough to czjuse any 'ivar jury to the bottom
crops of cotton, which -ere made during the activities of
individuals which had emerged from hibtornation. Following this,
of course, the question of sunmere rainfall became the dominant
one. Roughly spe,.-:L-:g, from A7absna weA-tward the season has
generally b?.en very abnormal ly d -. In many sections there was
nn precipitation from :,.:3y urtil. the middle of August, other
than purely local showers. This absence of general rains brought
about a very high degiee of climatic control, which was accentu-
ated by the urris'ally sma'!! plant growth of the season. As a
res'.it, tbro',.' ,at this territory weevil damage has been
abnormally ;:m-ll. Of course, in almost all localities there are
a few fields which for soima r-;icon or other produced a more
or less no.-mal growth of cotton and had sufficient weevils
to do sone damage, but these are the exception rather than the
rule. c ,r e:..-'le, in the viciny of aluah, where in a
no7r'al season alo-oct every fled of cotton is injured somewhat
by the we --'i-l, we have not over a half a dozen fields out of
,more than 500-.hich are rfnder obcr-a'ion which have experienced
any daagnse 7ha:-ever from the -ee'l t1J .s season. In all others
the ccrc-.i3' :o'i of low emergence follo.7ed by a high degree
of cl',maLic co-trl] liis ke!t thes veevi- at such a low ebb that
there has been absolutely no crop lo,.s attributable to boll
Sr *weevil.' T:e recent rains are ap-oarently stimulating multipli-
catJon of the weevils som...ehat, but the majority of crops are so
completely mature that this will have little significance as far
as the present se:-.cons cotton is concerned, the main -uestion
now being the one of weevil abrnaLanse for entering hibernation,
The suu'Gheastern States, p-artirularly Georgia anid South
Carol rra, had a very different season, experiencing more or less
the ordia-ry raifTa-.-, and weevil damage has been very much
heavier, though p-,obably not as heavy as a general rule as has
been the case for the past couple of years.
SDamage by uther insects this season'has been, as usual
sporadic and local. Th .rouaghout the ateas where there has been
a shortage of rainfall, both aphis and red spiders'have been
very exceeding y abundant, as is always the case in dry
years. and here ar.d-there they nave become sufficiently abundant
to actually injure the crop. The fall armywrorm has been

exceedirJ.y injiurious to cotton in many sections this year;
in fact, several districts 'ave done considerable poisoning where
ttliis species has cleaned. up bay crops and then moved on to
cotton. There has also been a rather unuau.l amount of injury
by miscellaneous lepidopt e'ous larvae of quite a number of
species. All of these outbreaks, however, have been purely
local.
The cotton leaf worm appeared early in July along the Gulf
coas-' in Texas, but was held ih check partly by climatic condi-
tions and partly by the fact that approxima.te3y 50 per cent of the
acreage in this territory wvas being poisoned for boll weevil
control, Drirg the past few days numerous reports have been
received of the leaf worm, extending up well into northern
Arkansas. It is now too late for this worm to do serious damage
as a general, rule, other than affecting the grade and staple
of the cotton, though along the northern edge of the belt the
crop is very light andr an invasion of -he worm any time before
ffrost will be a serious matter.

John B. Gill (July 2h): The :exican boll weevil is not so
destructive this year as in 1923 Cotto6n is fruiti g very well
and indications are that satisfactory yields will be obtained
in many fields in this section.

Texas ". D. Hunter (.u-ust 14): The leafwor--, first appeoarod in the
United States this season during the first few days of July,
about a mr-onth later than in 1923. Th3 first worris were found
in Calhoun County, on the coast of Texas. A few days later a
f-w infestations v-ore reported from Calhoun County southward
along tnc coast to Brownsville.
iTni-'.. infestatio s have ben exceedingly sli ht. Inspectcrs
who have boon in tho field for several weoks report that nc
fields have 'c:en cc'.pleotely defoliated. 7 r-,- most extreme
dan-age noted anywhere is in the vicinity of rovwnsville, where
an occasional fioid has been partly defc lia-ted in patches.
Generally speakin the insect is just about r.aintaining its
status and is not increasing the intensity of the infestation,
or spreading.
T.., reasons for the failure of tAo insect to spread are

E. P. Felt (July 29): Elm leaf-beetles are generally present
in small nLambers in the Luri n Valley, though occasional
group-s of *ti-2., Ejz'ti'la'lj ';lish elms, are seriously
injured. This latter may be associated with unusually
favorable food, such as European elms or exceptional near-by
winter shelter, such as sheds and belfries.

C. R. Crosby and assistants: In Dutchess County on August
2 these insects were very destructive and practically all
varieties of elms were skeletonized this year.

Geo. M1 Codding (August 20): In sections throughout Westchester
County, the elm leaf beetle is defoliating many of the elms,
This pest is worse than it has been for several years.

R, H. Pettit (July 23): This insect tas found at Monroe,
Mich., on this date. C. L., Burton, county bgricultur4l agent,'
has just brought in specimens and reports the partial
defoliation of a goodly number of elms in the city of Monroe.

T. D, Urbahns (August 3): Upon investigating an attack of
the elm leaf beetles on street trees in Fresno this species
was for the first time recorded from this State. Trees were
being defoliated on several blocks, and in about eighty
blocks were signs of infestation. The elm Is an important
shade tree throughout the State and every effort will probably
be made to keep the pest down. Three generations are expected"-
in the long summer season.

LOCUST

H. garman (August 23): Probably our most noticeable insect

A. E. Boadle, Xcting Chief, Lumber Division, Bureau of Foreign
and Domestic Co-'--.erce, DepartrE.nt of Commerce. (American Trade
Commissioner Douglas P. Miller, Berlin, July 24, 1924): The
present summer has been the occasion of extensive ravages through-
out the forests of eastern G-rrmcnv by a small ni4it-flying moth-
called the "owl moth" in Germany. This insect extracts the sap
from pine needles and in a short time caused the death of the
entire tree. It is estimated that during the present year 8
to 10 million solid cubic meters of lumber, particularly pine
and fir, will have to be cut and placed on the market.
Large forest areas in Brandenburg, Pomerania, West Prussia and
Silesia are being devastated by these insects and the entire for-
ests are turning *bro'?n ,:., shrivelled. It seems that the only
method of combating the pest:is the cutting down of trees in the
infested areas. -Further information concerning the effects of
this forest pest ,will be forwarded as it comes to hand.

Indiana C. R. Clevel-in2 (XA1,ust 19): Horn flies- on coW.; have not been
as numerous as in some seasons past.






- 253 -


Texas D, C- Parman (July 25): The horn fly has practically disappeared
from cattle during the month. It is rare to see more than
10 to 15 on any animal, and in the vicinity of Uvalde most
animals have none.

0. G. Babcock (August 6): At Sonora, San Angelo, Onona,
Sheffield, and Rexas Experiment Station this pest is reported
.attacking cattle and sheep; from 50 to 200 flies per animal
on cattle; few on sheep, especially short wooled.

D. C. Parman (August 21): The horn fly is very rarely observed
at" Uvalde except in the heads of the canyons or in heavy
timbered country along the rivers; never more than 100 on any
cattle.

STABLE FLY QStomoxys calcitran. L.))

Indiana C. R. Cleveland (August 19): On some farms the stable fly
is proving troublesome to both horses and cattle. Experimental
tests of various repellent sprays, conducted in nine northern
Indiana herds, are producing some very interesting data on the
value of such materials in protecting dairy cows from fly
attack.

Texas D. C. Parman (August 2): The dry hot weather at Uvalde has
practically exterminated the stableffly at this place, but an
occasional adult is observed in the canyons and in the farming
territory to the east. In a few p&ses where considerable
oat -straw has accumulated in protected places to which stock
have access the flies are quite noticeable.

SCE.TCIORM (Cihrysomva rna.ellaria Fab.)

Texas D. C. Parman (July 25): Adults of the screwworm fly have
diminished abouc 40 per cent in the trappings during the month
and are about normal for the season or a little above. Cases
of worms run about 5 per 1,000 in goats and sheep and 2 to
3 per 1,000 in cattle and horses. (August 21): The screwworm
fly had diminished at Uvalde until it is very rarely found
(less than 1 per 1,000). There has been no rain since June 30,
and we are experiencing one of the longest periods of maximum
tem.nBa-;ures since the station was established.

0, G. Babcock (August 4): At Sonora there has been no rain
since early June and the soil and air are very dry; flies
are therefore few in numbers.
