THE MORE IMPORTANT RECORDS FOR JULY, 1932

The grasshopper situation has not materially changed over the greater part
of the heavily infested territory.

In the New England and East Central States white grubs were reported as ab-
normally abundant, and heavy flights of beetles were reported from a number of
localities within this area.

The wireworm Heteroderes laurentii Guer. has been found in two additional
counties in Florida and five in Alabama.

The armyworm was reported as very abundant in parts of Iowa.

The fall Hessian fly survey in Ohio indicates a very material increase of
this insect, the infestation being 12.5 per cent in 1931 and 35.5 per cent this
year. It was also reported as being more abundant in Indiana and Nebraska than
it has been in many years, and generally abundant in Michigan and Minnesota.

The wheat stem maggot, probably associated with other wheat-stem insects,
was said to be doing considerable damage in the North Central States.

The chinch bug was reported as troublesome much farther north and east than
it is usually considered a serious pest. Reports of damage have come from Penn-
sylvania, Ohio, Nebraska, Michigan, and southern Minnesota.

SOver the greater part of the infested territory the oriental fruit moth was
not doing much damage.

The raspberry cane borer was reported generally from Maine, New York, and
Michigan.

The fall webworm was very abundant on pecan in the South Atlantic States
and the walnut caterpillar was reported as defoliating walnut in the East Cen-
tral States, westward to Kansas and Nebraska.

The corn ear worm was occasioning the usual damage for this time of the
year over practically the entire eastern part of the United States.

Many species of blister beetles were abnormally abundant on truck crops
everywhere east of the Rocky Mountains.

The tomato psyllid occasioned serious damae to potatoes and tomatoes in
parts of Colorado and Utah. In one -ly'ce as many as 1,000 nyrohs per hill were
found.

This month the Mexican bean beetle was observed for the first time in the
State of New Hkmpshire. It continued in destructive abundance throughout prac-
tically the entire infested territory during July.

The pea aphid was reported in outbreak n-'.nbers in the North Central States;
and in marts of Wisconsin the late pea crop was totally destroyed and a large
part of the early cro0 dama.'ed.

The harlequin bu '.as 'reported destructiveo in .Maryland, and W'est Virginia,
which is north of the usual destructive range.

The bagworm Was quite generally reported, particularly from ornamental ever-
greens in the Middle Atlantic and East Central States, southward to the Gulf.

The elm leaf beetle was appearing in destructive numbers throughout the
:Tc'.-. Thf-nland, Middle Atlantic, and r.st Central Stat.es, and there were isolated
outbreaks in Kansas, 7ashington, and Oregon.


TH3 '1'OR IFR0rTA1TT ENTOMOLOGICAL FEATURES I1: CANADA, FOR JULY, 1932

The grasshopper outbreak in the Prairie Provinces has been characterized by
a marked delay and irregularity in, the hatching of the eggs in many localities.
The outbreak is being dealt with by the w.idesoread distribution of poisoned
bait in infested areas, under the direction of provincial and municipal authori-
ties with whom Dominion officials are cooperating. General rains have modified
the sever vl7 of the situation somec'h;.t, and have promoted good growth of all
crops. In British Columbia, grasshoppers are remarkably scarce, althor-h an
increase is noted in the Chilcotin and I Nicola areas where drought conditions
continue to ,.revail.

Infestations of beet webwvorm.Tlrvae arc widespread in the Prairie Provinces.
Co nmon vc ed3 are chiefly subject to attack, but re-orts of damare_ to alfalfa,
grain, and flax have becl receivers from certain localities, particularly in Sas-
katchc.m. :'. In many areas serious damage has been effected to -:--den ml.nts.

Following the exceptionally heavy flight of June beetles over a wide terri-
tory in eastern Ontario, this s-mring, the -norrnous irnbcrs of eC~-s laid threaten
serious crop losses by white rhabs in 1933. In sout'-crn q-icbcc, .*.tc-rrub dim-
*," is bccrnri:.T incre-sin-ly pronounced.

Rcoorts indicate that the Colorr lo potato beetle is nbr.or-vllfy abundant
over a considerable D-art of its r .>e in Canada.

Increased abundance of Zirop-'n corn borer moths and e,-,s has been noted in
corn -lots. under observation in southern Ontario during; the season.

Dxtensive injury to 1latc-lnr-.ted r'iin ', a s-oecles of s-"cd mru,ot is noted
for the first time in certain areari in Sask-otchewnn.







-249-


The caragana beetle, or Nuttall's blister beetle, has severely damaged cara-
gana hedges, beans, and peas in sections of the Prairie Provinces.

Severe losses of onion crops due to the onion maggot are reported in south-
ern areas of Saskatchewan and Alberta.

The rose chafer is in outbreak form in parts of southern Ontario.

The striped cucumber beetle is destructively abundant on cUlcurbits through-
out southern sections of eastern Canada.

In the fruit-growing areas of the Dominion, reports in general would indi-
cate that the more important insect pests of fruit are at a low ebb.

Certain species of aphids are markedly abundant in the Prairie Provinces.

A European species of sawfly, Diprion polytomum Hartig, is infesting white
and black spruce, particularly the former, throughout a large part of the
Gaspe peninsula, Que. This species, which is a defoliating insect, Was dis-
covered in the Gas-pe in November, 1930, but there is no evidence as to when and
where it first became established there. The eastern spruce bark beetle is
also attacking the trees in the affected area and has caused the death of
large numbers.

The European pine shoot moth is an increasingly abundant and destructive
pest in pine plantations along the north shore of Lake Erie, in southern On-
,tario, and occurs in light to moderate infestations throughout the. Tiagara
peninsula. Eradication and control effort- are being continued.








GENERAL F E D RS

"-7?ASSSHOPP? S (Acrididae)

Geor-ia. 0. I. Snapp (July 1.2): ''Grasshoppers caused serious injury to corn at
Byron before farmers used poisoned-bran bait. (July 22): ?he bird rass-
hop.:,r (Schistocerca americana Drury) is very ob' -ant at Fort Valley and
c."-r'*; considerable darYAe to corn, beans, cotton, and youn.- peach trees.
In one locality this grasshopper, emer:in.T from a wheat field, had completely
defoliat'e-d cotton and corn interplanted with beans in adjoini-ig fields.

Florida. J. R. 7-tson (July 25): Grasshoppers mostly, S. qn Prica"a, alt hou.;h, not
epidemic as in the West, are more abundant than I have ever la--o'n them in
Tlorida d.rin- the 20 Years of m-y experience.

Kentlicky. W. A. Price (July 26): Grasshopper ny-mphs are rather a'b-.:ia,.t in
the -.rasslands. The frenucent rains during the summer have ':ept the ne-ilows
green and for that reason we have had no complaints rertrdin-_ this .est to
date. App'rentlr they iave been content to remain in the srasslanrs, thus
saving the cultivated crops.

Michigan. R. Hutson (July 23): Grasshoppers (:elanoplus bivittatus Say, M.
atlans_ 71iley, and Camnula pellucida Scudd.) are very aburn-ant over all the
upper peninsula.

Wisconsin. Z. L. Chambers and assistants (July): Grasshoppers are reported as
very ab.'i-'..i'.t and doing some damage throughout the State. (Abstract, J.A.H.)

Minnesota. A. G. Ru-i--les (July 23): "Gr:s'hop--crs are very abundant. Our ca.-
;-*>:. in Minnesota, ,v-ere $250,000 was spent for poisone -bran bait, has
succeeede in savi;-. the small train. We are worried now about the late crops.

ITorth Da2kota. J. A. I.'2-nro and assistants (July): Gras1hpTrers are moderately
to very abi.ndant in the northeastern _roup of counties, also in 7ottineau
and Renv'lie Counties, the prc-.lominant species beini- .. boivittatus. Alth'oueh
small ar- : show considerable fungus, dry weather has prevented the g-ncral
prevalence of the disease. (Abstract, J.A.H.)

Iowa. H. E. Jtqes (July): We have recently c',rpleted a 1,700-mile trip around
the rim of Iowa where we collected in 43 counties. As far as I can see,
th:e are fewer grasshoppers than usual except for a few local spotc.

T,-er' .>:-1. I. H. .Swenk (June 20 to July 21): T_. situation during the -.onth was
alons the line of a continued :;--:'ction of the population, in p-irt through
thie direct effect of heavy rains, but more lar-oly thro'..:-h the coming : into
activity of the fungous disease produced by .'lpi gryl]i. Our first reports
of the destruction of grasshoppers in lar-e numbers by this disease are dated
June 25, and they have continued to July 21. All over southeastern Nebrask.a,
from Fichrdcon County. west and north to Dv':son, -rown, and Sta.nton Counties,
we hiv l; reports, or have made observations of the prevalence of this
diieasu-e a rir.- the period here covere.-'. Bc-,nnin" the last weekly in May a
o' riod of rainy weather began in eastern,T'br-.i'a, which continued until early
in J'll-, anc :'ing the latter part of this period the temperatures were high,
pro cu-_i,- much warr-:, r.ist, sultry weather. As a result of the direct effects









of the late May and June rains, and later the destruction of millions of part-
ly T-rown or adult grasshoppers by. the fungous disease, together with a heavy
destruction of the pests by early poisoning operations, the grasshopper sit-
uation in eastern Nebraska has eased enormously; nevertheless, in scattered
localities, grasshoppers survived in large Enough numbers that they did
considerable damage when they started entering the corn toward the middle of
July. Such localized damage ihas been reported especially from Holt, Custer,
Platte, Cuming, Saunders, Hall, NTuckolls, and Richardson Counties, from June
24 to July 17. Enough grasshoppers persist along the Niobrara Valley, and
along the river in our northern Missouri River counties, to require continued
serious attention. Rather more general injury has developed in the western
half- of the State.

Kansas. H. R. Bryson (July 17): The situation in Kansas is much more cncourncjing
than it promised to be earlier in the season. Prof. G. A. Dean reports the
grasshoppers very scarce in counties in northeastern Kansas where considerable
damage occurred last season. Requests for information regarding poisoned-bran
mash indicate that damage is expected in some western n counties. Grasshoprr.2rs
are quite abundant at Manhattan, but not in outbreak numbers. Wet weather in
northeastern Kansas favored the spread of grasshopper disease.

Oklahoma. C. F. Stiles (July 26): Grasshoppers are extremely abundant along creek
banks and fence rows in various sections of Oklahoma. The outbreak is not
general, but localized in communities where there is an abundance of waste
land. The yellow leg (M. differentialis Thos.) is the most abundant.

Alabama. H. P. Loding (July 17): Grasshoppers of various species in great numbers
are doing dajna-e to Satsuma orchards, dahlia plantings, and gladioli.

Mississippi. C. Lyle (July 20): On June 30 a correspondent at Holly Bluff sent
specimens of grasshoppers (Schistocerca sp.) with a report that quite a bit
of damage --ad been caused to cotton in that section, in some instances entire
fields having been destroyed. Correspondents at various other points in the
State, especially Yazoo City and Essex, wrote that grasshoppers were present
in large numbers and causing considerable injury to cotton and soy beans.

Colorado. G. M. List (July 23): Grasshoppers are from moderately to very abr-idant
in eastern Colorado.

Utah. G. F. Knowlton (July 12): Many species of grasshoppers are largely adult
at the present time. The lesser migratory grasshopper (M. atlanis) and
Packard' s grasshopper (14. packardi Scndd.) were damaging wheat and alfalfa at
Marysvale. The warrior grasshopper (C. pellucida) is extremely abr'n.rant be-
tween Richfield and Annabella.

Nevada. G. G. Schweis (July 26): Serious outbreaks occurred on Nevad.a-California
line and also in Douglas County, Nev. Several species of hoppers involved.

California. Monthly News Letter, Los Angeles Co. Agr. Comm. (June 29): In common
with other sections of the State and country, grasshoppers have made an assault
in the Antelope Valley this summer. Nine species are working on grain and
alfalfa fields in the foothill district on the north side of the Valley and are
causin-g some damage in places. Although a few acres of grain have been
completely destroyed, most of the infested fields have suffered only the loss






-252-


of leaves, on the stalks, allowing the heals to mature .satisfactorily. The
,harvest has not been Interfered with.
CJTWQRES (1;octuiiidae)

Florida. J. R. Watson (July 26): ''The semi-tropical army .'orm (Proderia eridania
Cram.) is shoving up in some sections of the State. As usual, it is attacking
-.-a-s as its first choice.

Maine. C. R. Phipps (July'"72)t iftworm (Arotis ypsilon 2ott.) are very ab -ndant,

Ore-)n. D. C. Mote (July 23): A widespread outbreak of Prodenia praefica Grote
has been reported from Lane County southward, including Jachson and Klar-iath
Counties and also a local outbreak in yamhill County of LAcophotia riarcaritosa
saucia Hbn. in 20 acres of alsike and 10 acres of red clover.

W:ITE3 GRTUBS (Phyllopha.?a spp.)

Massachusetts. A. I. Bourne (July 25): White grubs are moderately to very a-
bundant in one potato field, where 22 grubs to a hill were collected. These
fields were in sod last year. White grubs were so abundant and doing, so much
injury to a field of Cobblers that it was necessary to dig the field two or
three weeks early in order to salvage as much of the crop as possible.

Rhode Island. A. E. Stene (July 23): White grubs are very abundant in some place!

'Torth Carolina. R. A. St. George (July): During June larvae were active in the
State Forest 1;arsery seed veds located near Clayton, where they caused serious
injury to loblolly and shortleaf pine seedlings. During July many of the grabi
were found to be parasitized by what may prove to be one of the robberflies.

Ohio. T. H. Parks (July 20): Newly set strawberry beds have suffered from more
than the usual white-grub injury. In some cases beds have been torn up and
planted to other crops because of the injury. In a field near Cleveland
aster roots were being seriously damaged and many of the plants were dying.
This groiind :.d grown up to weeds last year.
E. W. Mendenhall (July 14): White grubs are numerous on glai.olus in a
nur.r-T" at Gore, Hocking County.

Kentiucly. W. A. Price (July 26): 'White grubs of Brood B were reported injuring
strawberry plants at Russell and corn at Lexin-ton.

Wisconsin. E. L. Chambers and assistants (July): June beetles are stripping
deciduous trees in many parts of the State. (Abstract, J.A.H.)

Minnesota. A. A. Granovsky (July 11): The mass flight of June beetles is over;
the maxirurn flight occurred about the middle of June. The adults are still
found, but not in lar-e numbers. Contrary to common opinion the oviposition
rcadil-' takes place in cornfields free of weels as well as in well cultivated
r-i..:berry patches. The eggs and newly hatched larvae were found in such
situations without difficulty, c.rccially near the oakc trees.








A SCARABAEID BEETLE (Pachystethus mar.inatas Fab.)

North Carolina. RT W. ieiby (July 11):... Tis beetle appears to be present in more
than average nurnbers, causing damage to pecan and walnut trees in the eastern
section of. the State.

Fl o r. id* .r WIRB ORTS (Elateridae)

.Florida and'Alabamia. K. L. Cbc-erham (June): 'On a recent scouting trip 0. T.
Deen found Heteroderes laurentii Guer. in two additional counties in Florida,
namely, Okalosa and- Walton and in five additional counties in Alabama, name-
*:ly, Monroe, Conecuh, Covinton, Geneva, and Houston.

Connecticut. D. S.-Lacroix (July 2): -Larvae of the eastern field wireworm
*(phelet.es ectypus Say) are more abundant throughout the tobacco-growing areas
in the Connecticut Valley, and are working muchI later than in 1930 and 1931.
Usually they are through by June 15 6but this year have been working on plants
up to July 1.

Nebraslka. M. H. Swehk (June 20 to July 20): During the first week in July a
Stanton County correspondent reported that'he -had considerable injury in his
cornfield by wireworms, which proved to be the common corn wireworm (Melanotus
cribulosus Lec.).
Idaho. R. W. Heagele (July 26)1 Wireworms, Pheletes californicus ..ann.,are very
abundvant in: southern Idaho.

A. ASIATIC B"-TLE (Anomalaorientalis Waterh.)

Connecticut.- R. B.. Friend (July 25)': The abundance of'adults is about normal.
Adults have been collected this year outside' the quarantined area, and the
insect is slowly spreading throughout the city of NewHaven.
E. P. Felt (July 25): The Asiatic beetle was found in abundance in Putnamts
-Cemetery, Greenwich.

-ASIATIC GARD BE.TLE'(Autoserica castanea Arrow)

Connecticut. E. P. Flt (July 25): *The Asiatic garden beetle occurs sor.,-ew'hat
generally on Ocean Drive 'Vest, Shippan and Stamford. This is presumably the
first record for this insect in southwestern Connecticut.


EC0 2 L.E AL AN D F 0 R A GE C'R 0 P I N S E C TS

ARMYWORM (Cirphis unipuncta Haw.)

Iowa. H. E. Jaoues' (July): Armtn,.orms are scarce in Howard County, moderately
abundant in Dickinson, .met, O'Brien, Cerro Gordo, Hardin, and Crawford
Counties and very abundant in Lyon and Floyd Counties.

North Dakota. J. A. Munro and assistants (July): The arm:'worms were first Qbservet'
Son July 7, and-by- the middle of the month were reported as very ab'ndant in
Burleigh, .-'Me-Lean, Star.:' and Walsh Counties. (Abstract, J.A.H.)

WRHAT

HESSIAIT FLY (Phytophaga destructor Say)

Ohio. T. H. Parks (July 23): At the completion 6f the annual -wheat-insect
survey the Hessian fly was found to have increased more than anticipated.
The average of straws infested this year was 35.5 per cent, compared with
12.5 per cent in 1931. Since some straws carried more than one flixseed, the
infestation is now more than three times as heavy as in 1931. This has happen-
ed. in spite of the fact that May and June were deficient in rainfall. NTearly
all of the infested straws remained standing and matured a fair yield of hinh-
quality wheat testing 58 to 60 pounds per bushel. Yields were under e.pecta-
tions in the southern half of the State owing to the drought of May and June.
North of Columbus the yields were good. The fly did not cause very much
reduction in yield in spite of the high infestation in some fields. Fourteen
fields averaged between 70 and 92 per cent infestation, the highest infested
field hIaving been sowed after the fly-free date. This Jear the .early-sowed
fields did not carry any more infestation at harvest time than those fields
sowed after the proper seeding date. The early sowed fields were heavily
infested during the fall and winter, but at harvest time there were very few
lodged straws in these fields and they suffered no great yield reduction.
However, they did not usually yield so well as the later sowed fields, as the
past winter was not severe on late wheat. During the survey more than the
usual number of flaxseeds were found to be desiccated and to contain dead
larvae. 'Parasitism was also rather high. In making the survcy,, ten fields
were examined in each county and 100 straws examined in each field. Following
are the percentages of- straws fo'and infested in each of the 24 counties
surv'.'c:'d: Fulton, 27; Henry, 39; Wood, 51; Putnam, 17; Sencca, 62; Huron, 68;
.'7r. lot, 30; Richland, 28; Wayne, 58; Stark, 56; Holmes, 54; Knox, 25; Delawa
28; Hardin, 16; Champaign, 28; Clarh, 29; Miami, 47; Butler, 32; Clinton, 33;
Clermont, 24; Pickaway, 20; Fairfield, 17; Rost, 7; Shelby, 52; average for
State, 35.5 per cent.

Indiana. 71. 0. Deay (July 25): The Hessian fly is more abundant than for many
years. According to our records many fields i.ave from 90 to 98 per cent of
the stubble infested. The infestation in the southwestern part of the State di
not become so severe as earlier records would in"Iicate. Infestation in the
central part is much more severe than it has been for a number of years.

..ichigan. R. Hutson (July 23): Generally abundant throu h the southern end of the
lov/er peninsula.

Minnesota. A. G. Ruggles (July 26): Quite bad in winter wheat in a few southern
counties. ITo definite reports from spring wheat.

Nebr-':.a. M. H. Swenk (Juno 20 to July 20): Wheat harvest completed, and the fear
that the Hessian fly would make severe inroads upon the yield in southeastern
Nebraska were fully realized.

.-AT STIN FAnOT (Morom-yza ancricana Fitch)

Michiran. R. Hutson (July 8): M. americana is present to thie extent of approxi-
m.atel:- 1 per cent in most fields 6 barley in the lower peninsula.






-255-


Minnesota. A. G. Ruggles (July 26): The wheat stem maggot is more abundant than
usual. In some fields 20 per cent of the heads are affected.

North Dakota. J. A. Munro (July 18): Wheat stem magTot widely distributed, but
few reports of serious loss.

Nebraska. M. H. Swenk (July 20): During the last week in June the wheat stem
maggot was found doing serious damage in some barley fields in Dodge County.

FRIT FLY (Oscinella~frit L.)

Minnesota. A. A. Granovskyr (July II): The frit',fly assumed considerable impor-
tance this year, infesting several fields about St. Paul. Some plats at the
experiment station showed infestation from 10 to 35 per cent or even higher.
The infested plants stooled profusely without forming heads. Injury is severe
and losses are considerable.

SAY'S STINK BUG (Chlorochroa s Stal)

Utah. G. F. Knowlton (July 12): Say's plant bug is abundant and damaging the
heads of barley at Beaver.

Colorado. G. M. List (July 23): Say's plant bug caused a moderate amount of
injury to winter wheat in northern Colorado,

GREM BUG (Toxoptera .raminum Rond.)

North Dakota. J. A. Munro (July 18): A few reports of serious injury to wheat
in northwestern counties. have been: received. Ladybird beetle and s.-rphid-fly
larvae are checkin. the infestation.

*WHFAT JOINT WORJA (Harmolita tritici Fitch)

Ohio. T. H. Parks (July 23): The wheat joint worm has not increased any over last
year and no serious injury has occurred. The straw infestation in different
fields averaged from 0 to 8 per cent but *none of the straws was bent over or
lodged because of the insect.- It 1las been many years since it has been very
serious.

Wisconsin. 32. L. Chambers and assistants (July): The wheat joint worm is reported
as doing considerable damage over considerable areas in Oneida, Kenosha,
Portage, Chippewa, Pepin, and Grand Counties. (Abstract, J.A.H.)

WHTAT STM'!SAWFLY (Cephus cinctus Nort.)

New York. IT. Y. State Coll. Agr., Weekl Tews Letter (July): By July 18 about
one-third of the apple curculios had uipated in eastern TeowV York and adults
started to appear on July 21 in that section of the State. (Abstract, J.A.H.)

Kansas. H. R. Bryson (July 18): The apple curculio is reported by Dr. R. L.
Pa.rker as doing considerable injury to the current year's growth of apple twigs.
This, no doubt, is worse owing to the scarcity of fruit. Severe injury to the
fruit has also occurred. Some orchiards have a total loss of fruit due to injury
by the insects in northeastern Kansas.

earliest pupation for this latitude.

Tennessee. H. G. Butler (June 29): Borer treatments were omitted by most of the
growers at Harriman last fall and during the present month it has become very
evident that considerable injury has resulted. Several of the better orchards
in which this pest has been of minor importance are now to be classed as
heavily infested. Adult emergence be.-an 'in the insectar- and in the "rchards

developing peaches at Chadbourn. As -nany as six to eight have been observed
on a single peach, leaving punctures over practically all the surface. Hardly
a peach on some trees has been exempt from this attack':. The work of this
insect is characterized by dozens of minute punctures over the outer skin with
darker areas around those punctures in the flesh of the peach. This insect is
also abundant on developing cowpeas where the whole pod is speckled with the
punctures. In many cases the attack is so severe as to cause t-he you.g pods
to dry up before the seeds are formed within.

Ohio. T. H. Parks (July): We are getting reports from many sections of the
State of the injury that has been done to tomato fruits. Th.e insect is also
being found in the heart leaves and tassels of sweet corn. Heavy injury is
expected to sweet corn from the later generation of larvae. Grenhouse
men in Cuyahoga County are -oreparing to screen their greL-nhouses against the
moths to protect the October and early winter tomato crop. These men suf-
fered heavy loss to greenhouse tomatoes last fall.

Indiana. L. Pierce (July 13): The early tomato crop, an important commercial
crop in Knox County, is threatened with almost complete destruction on ac-
count of a very heavy infestation. Some fields were L.bor.doned at the be-

Monroe--are suffering, from a 50 to a 75 per cent infestation. Growers from
Grand Rapids report heavy losses on sweet corn in the field and from to-
matoes under glass. Yesterday re received a n-zr.ber of corn ear worms from
.p-_rta where they were 'or.king. on pop-corn. This particular crop is rather
slow and the worms were working in the tassel. They are fully two-thirds
grown. At Mlonroe many of the larvaec are ready to pupate.

corn ear storm, and it is at -oresent working at Monroe, St. Joseph, Coloma,
East Lansing, Bath, Srarta, Grandd. Rapids, Kent City, Allegan, East Sauga-
tuck, and Feninville. .All of these re-oorts came in between the 13th and the
22d'of'July. I have seen specimens from several of these places, and in all
cases the corn ear worm is -oenetrating the sides of the ear through the
husk and chewing the tassel while still rolled among the lQaves.

Louisiana. C. E. Smith and P. X. Harrison (June 29): The species was unusual-
ly scarce in the vicinity of Baton Rouge during June, as determined by

dered the crop worthless. By the middle of July the first-brood larvae
were maturing and numerous Duoae were found. At the present time the adults
of the first summer brood are beginning to appear in considerable numbers.

INSECT C01NDITIONTS PUERTO RICO DUPIIUG JULY, 1932
G. ST. Wolcott
Insular Experiment Station, Rio Piedras, Puerto Rico.

Two outbreaks of the cottony-cushion scale (I cery a purchase Mask.), from 6
to.--9 months old, have booeen found recently in Pueblo Viejo. The heaviest original
infestation, at Palo Seco, is now practically eliminated, in largo part owing to
spraying and the Australian lady beetle, during dry weather, but the final clean-
up is almost entirely due to a light gray fungus, as yet undetermined, which has
appeared in great abundance during the recent wet weather. This fungus has also
cleaned up a heavy infestation in a pocket in the hills west of B- ya-on, but in
an adjoining grove, not protected from the wind, the scale is more abundant than
a month ago, for conditions have been too dry for the fungus and too wet for the
'beetles, and the latter have entirely disppuuared, despite the fact that there is
an increasing abundance of food for them in this grove. At the present time they
are known to exist in only one grove, and not in large numbers there.

The agricultural urgent at Arecibo reports the chinch bug (Blissus leuco-
terus Say) as being destructive to young planted sug-rc-'.e, about 4 months old,
at Hatillo. This is the first record of injury to this host in lh:t, Rico, al-
though the chinch bug has previously been reported on sugarcane on Vieques Ialrnd.

Infestations of lima beons (at Isabola) continue to be confined to one
species of pod borer, Etiolla zincrenella Troit., and have been averaging from
30 to 40 caterpillars per 100 pods. This is several times as many caterpillars
as wore in the lima beans last year.

R. F-xon and A. S. Mills (May 3): The new facts, so far as Puerto Rico is
concerned, were that Fundclla cistipennis Dy'tr was usually present in smrll num-
bers in lima beans that were shipped to the States. In previous seasons E.
zinckenclla appeared to be more pr-vaLlent than Fundella but this season Fundella
larvae were found more frequently in the pods of lima beans than either Maruca
testulalis Geyer or E. zinc7enella. The infestations of F. cistipennis were light,
the heaviest being 3 per cent, found in a hamper from Istbelr. This insect was
found to be present in shipments from Loiza, Vega Baja, Arecibo, Isabela, and
Adjunitas. E. zinckenella was found in only three shin ents of lima beans and
four of gandules.

PLANT QUARAi:TIiTE ATD CONTROL ADnINISTRATION

Notes abstracted from "News Letter," July 1, 1932

(Not for Publication)

MEXICAN FRUIT FLY (Anastrcpha ludens Loew)

The operation of some 5,600 flytraps resulted in the taking of 5 adult
Mexican fruit flies on the American side of the Rio Grande during May. These
flies were taken in four groves, three of which'h'ac previously been reported
as infested. No infestation had booeen previously reported from the other
grove, which is located about 6- miles from the nearest -oreviously reported
infestation. Fermenting malt was used principally as the bait in thc traps.

In addition to the A. ludcns taken in the traps, 181 adult A. oallens
Coq. werc also taken. The population of pallens seems to have decreased con-
siderably since, with a considerably larger number of traps in operation,
the take of pallens showed a decrease of 536 adults from the number taken in
April. This fly seems to occur wherever the "La Coma" plant grows. Larvae
were taken during the month as far west as Zapata and as far north as Raymonds-
ville, Texas.

GIPSY MOTH (Porthetria dispar L.)

T-z first gipsy moth egg clusters were observed hatching this year on
May7 2. Hatching became general about May 9 and the maximum hatch occurred
about May 13. Thcse observations were made in several p1nlcos cast of the
barricr zone.

Up to and including May 28, there has booeen found by the Federal force in
the barrier-zone area of southwestern M!Aassachus'tts and northvcstern Connec-
ticut a total of 67 infested sites aggregating 885 new gipsy moth egg clusters.
The tons infested in this portion of Massachusetts arc New "arlboro, Otis,
Sandisfield, Sheffield, and Tyrinaham. In Connecticut, the, barrier-zone
towns infested are Canaan, Norfolk, North Canaan, Solisbury, and Jarren. The
farthest infested point in the barricr-zonec area this year, in relation to the
Ne; Yorf: State line, is apnroximatcly 15 miles east of it. Salisbury, Conn.,
borders on the New York State line.

GLADIOLUS iTHRIPS (TaoniothrioGs glardioli T:. & S.)

The flndiolus thrips, T. gladioli, has recently been found infesting
gladiolus corms in ,Tashington, D. C., and vicinity, according to a manmorandum
received from the Bureau of EntomoloJ. A brief survey by Bureau entomolo-
gists among 7 loc.l growers and dealers resulted in finding infested corms at
tv'ho shinjton ctoros from Vhich mnny lots had been purchased, and an infested
shi'oment had just booeen received n. a local grower.
