INSECT PEST SURVEY BULLETIN

OUTSTANDING ENTOMOLOGICAL FETUReFS IN THE UNITED STATES
FOR THE PERIOD FRO~O NOVEMER 1, 1923, TO PRIL i, 1924.
Last winter witnessed some entomological developments that are extremely significant to the Survey. The symposium on methods of estimating insect aoundance and damage which occupied the attention of the Arerican Association of Economic Entomologists at tneir annual meeting at Cincinnati brought out many interesting features of survey wcrk. The papers were remarkaole for the broad philosophical way in which the subject was handled and clearly indicated the rapid advance that is being made in basing entomological practice upon established scientific principles instead of empiricism.
The appointing of a co mittee to standardize methods of estimating insect abundance by this Association and the response vhich this committee has received from the members of the Association is enlightening, and will undoubtedly lead in the immediate future to the accumulation of a much more useful rass of data on this subject.
The winter was marked by notably cool weather over the greater part of the United States during October, followed in the latter part of thle month by a w"farm spell. Precipitation as a rule was ronnal to beow normal except in the northeastern States arnd Great Plains, unusually wet weather occurring in western Kansas. East of the M ississippi River the cool weather continued through Iovemobr, while over the central valley and the Great Plains the weather was decidC.edly warmer and in the Dakotas it was the mildest recorded in 30 years. The Southwest had cold rainy weather during November while the Pacific Coast was experiencing a drought. December was unusually warm, the weather in sore places in the New England States being the warmest ever recorded, while the end of the month brought sc.e very cold weather in the Northwest and from the Great Plains westward. January witnessed extreme frost damage in the South Atlantic States 'hen a very severe cold wave spread over this region on the 5th and 6th of the month. The Gulf re.icn experienced similar cold weather, and but for cloudy weather serious damage 7ould have oeen done in Floride. On t-%e 2d and 3d of J anuary very severe col vweather was felt in California, and during the month the entire -estern region was dry and the East wet. February started out mildly, but rapidly turned cold as the month advanced, severe freezing weather occurring in the South Atlantic, Gulf, and Florida regions, while the temperature in the Rocky Fountains and on the Pacific Co ast was about normal.
The European corn borer made very slight increase in the infested territory in the western part of its distribution. On the other hand, two new I infestationsutrebaisouthward to Long Island, making a vry rateriql advance toward the southeastern corn belt.
-~T lN ~ )R
The Hessian fly has appeared in rather alarming numbers in/western Kansas following three years of excess precipitation. Heretofore this region has been beyond the Eessian fly territory.
The unusually cold weather occurring over thle Southern States appears to have materially affected the hibernationeof the boll weevil in the Delta Region, as is shown by the examinations made at the Delta Laboratory of the Bureau, where the average number of live wee-vils per ton of moss wras the lowest ever recorded, oeing 0.5. A full account of the records since 1915 appears in the body of this Oulletin.
This severe weather so completely destroyed the remnants of the sweet potato vines and potatoes in the field that this, combined with a scarcity of sweet potatoes held by the farmers, has very materially reduced the number of sweet potato weevils in the infested territory.
A high percentage of eggs of the Australian tomato weevil in the rearing cages of the Bureau's Gulfpocrt, iiss., Laooratory was destroyed by the freezing weather of March. Apparently the numoer of larvae and adults in the field was considerably reduced.
The outbreak of the potato tuber moth on the Eastern shor6 of Virginia,
which developed last fall, extends well up into Acccrrac County. This is the first reccrd of the occurrence of this insect as a potato pest in the Eastern United States.
An outbreak of tke pepper weevil was brought to light in October in the La Habra district of California. Up to that time this pest was known only from aoout esilla Park in Nev ]exico and in southern Texas. Later investigations showed the pest well established in practically all commercial pepper-growing sections in Orange County and in the San Fernando Valley in California, one grower reporting a loss of e7,000 in last year's crop.
The discovery of the Oriental fruit moth in the vicinity of Valddsta, Ga., some 70 to 6C miles from the Fort V :ley peach section is a matter of unusual interest. Active steps are oeing taken by th.e State Entorologist to eradicate the infestation if possiole.
OUTSTPIDING ENT0'OLOICAL FFATURPS FORP, CPNADA, NOV~EMBFR 1, 1923,TO TPIL 1, 1924
The winter of 1923-24 has been a very mild one throughout the greater part of the Dominion. The temperature, for the most part, has been well above normal with the exception of a cold snap in Feoruary throughout Eastern Canada.
The snowfall in the Western Provinces was light, the open range being almost free from snow late in February so that no feeding of stock was necessary. The snowfall in Ontario, Queoec, ad the Paritive Provinces generally speaking was much heavier, the ground being 'well covered with a blanket of snow throughout the winter so that except in certain cases there was little frost in the around.
On the whole, the winter has oeen a very favor-Lole one both for crops and their insect enemies.
The European corn borer caused reasuraicle losses to ccrn in 1923 ov ,r a much wider area t1ian in the previous season., in the heavily infest Dd sections of southern Ontario. in the control ai-ea Li-.f e_-ta:-io.i increased by 10 per cent ever 19242, a'Luhou7,h with this increase it is still 2-2 per cc,-,t t1lan in 19411; the act, ual f ie ld lbs s es in this ai ea in 19 '3 v,,Prc 7egligible.

farmers awaited the announced date of safe seeding, and as a result these counties that contained so much heavy infestation by the fly in the spring showed comparatively little of it in the fall. In
other counties, unorganized, where the Hessian fly had not done
enough injury in the spring of 2923 to indicate that organized
effort to sec-,ur.e a general delay until the date of safe seeding, would be suc~esfu l, the present infestation is more severe than it was a year ago. The organized campaign in Furnas County was
not successful, for a comparatively small percentage of the farmers awaited the dade of safe seeding, and as a result the infestation there is much increased at this time as compared to a year
ago, except in the case of the small percentage of farnners who
actually awaited the safe date before seediig their wheat. This
area of hear infestation in Furnas County extends even more heavily west into Redwillowv; County and east into Harlan County, thence less heavily, but still seriously, into Phelps and Gosper Counties
and the southern part of Dawson County. Another center of serious
infestation is in Jefferson, County and the southern part of Gage
County, and this extends northward into Saline and Fillmore Counties. Other counties from which re-oorts of seriously injured
fields have been received are '7ebster, Butler, Dodge, and Sarpy
Counties. In brief, the geography of the Hessian fly infestation
at this time is different from that of a yetr ago chiefly in that the counties that were worst infested a year ago are now comparatively lightly infested, while the present heavy infestation, except in Furnas County, is in counties that were not heavily enough
infested a year ago to secure general interest in a program of late
CHINCH BUG (Blissus ]eucopterus Say)
Ohio H. A. Gossard (March 22): There are very few chinch bugs to be
fourAd in the State and we are not expecting much trouble from them.
Illinois W7. P. Flint: No very extended examination of chinch bug hibernating quarters has oeen made up to this time. Those made thus far
indicate about the average winter mortality in the central Illinois counties with a rather high mortality, in some cases as high as 50
per cent, in the northern counties. These counties are just becoming infested with the ougs. Present indications are that there are enough chinch bugs in hibernation to cause moderate to heavy
damage to susceptible crops throughout the central and north-central
counties of Illinois during the coming season.. A nore careful chinch bug survey will be conducted during the next two months.
Missouri L. Haseman (March 12): In spite of severe winter on Farch 7
examination of clump and blue-grass harbors in sheltered places
show live ougs abundant. They were observed in short and scattered grass shelters. Protection seemed poor, though, on south slope, This leads me to believe that we will have chinch bug trouble again

rw, :-,,Iy -t,-oward t,:ie tLan
straight across the State so that we now find it pretty generally
over Uforcester, Middlesex, and Essex Counties. Few, if any,
reports have been made of finding it in the southeastern area of
the State. This advance has been widespread so that the infestation is very generally distributed Throughout orchards, bout in northern and northeastern VWorcester County, as a general thing,
the infestation is not particularly heavy as yet, except in some
isolated cases, and of course it is confined chiefly to its principal host, the Baldwins. One grower who has pruned his orchard
of 1,000 MacIntosh trees failed to notice any evidence of its
presence, while Baldw;ins in clocks alongside showed quite heavy
infestation. Here at the College, for two or three years in
practically all of the clocks of apples, we have had the pest in considerable abundance, particularly on Baldwins. Last year, as
I mentioned, the foliage oy the riddle of August was bronzed so that it became very conspicuous. However, examination during
the winter season failed to disclose any amount of overwintering
eggs. The sare %was true of practically our whole planting of
apples. Our sole infestation of any consequence is apparently limited to our rain clock of rlu-s which is a variety block containing a considerable number of trees. Here the infestation is
light to fairly heavy, showing an apparent preference of the rites
for certain varieties. According to reports from Connecticut,
this should largely oe attributed to predacious forms as the last year, here in Arherst at least, was particularly favorable to the development and multiplication of the Trites. I ray say that we were screvwhat surprised to iote this condition of things here at
the College follo-ing such a marked infestation last year, although
our observations throughout the State in the last few years have
called our attention to somewahat similar, although less rarked
cases. That this is a purely local matter, confined principally
to our own orchards, is borne out by the fact that some of the
large growers to the south of us, just north of the Holyoke range, are finding the pest so abundant that they are conterplatinz special oil sprays for :its control. It would appear, from our experience ere, that it is very difficult to rake any general
statement regarding infestation by this species, it being apparently a matter of individual orchards, to a very large extent.
Connecticut Philip Garman (March 24): The European red Tnite is quite abundant in the northern part of the State. Eggs are more abundant
than last year.

damage with a ncrcl or vnfavo -able sui=mer. Furthermore,
it should be re erd that the above figures do not necessarily apply to the eLtire cotton belt, and each district should bear in
mind the minimum cemperatures they have experienced during the
winter and figure accordingly. Also the type of shelter
available is exceedingly important, as these records are taken
in the northern portion of the zone in which Spanish moss is found, and during cold winters a heavier mortality is found
in this zone than in the some.vhat more northerly sections where
the weevils secure better shelter.
Oklahoma E.E. Scholl (March 18): A general snotistorm of the last few7
days has delayed the emergence of insects in Oklahoma. There
was some activity of boll -reevils before this cold spell st~ahk

SUG.R-CANE BORER (Diatraea saccharalis Fab.)
Louisiana Monthly Letter of the Bureau of Entomology, No.ll, February,1924:
L. Ia Janes,of the Bureau of Agricultural EconomicS,cooperating with T. E. Holloway and W,. E. Haley of the Bureau of Entomology, estimates the normal loss to sugar.-cane in Louisiana due to the sugar-cane moth borer to be 570 pounds of sugar per acre. The
loss for 1922 is estimated at 510 pounds, and for 1923 at
690 pounds. The borer is responsible for similar damage in
Florida, Mississippi, and Texas, and it also seriously injures
corn, broomcorn, kafir, etc,

WHITE-MARKED TUSSCCK MOTH (Hemerocahpa.leucostiema S. & A.)
Illinois W. P. Flint: Egg masses of the tussock moth are more numerous
than usual in cities in the northern half of-Illinois. The
infestation is not as heavy as that occurring in some localities
during the past outbreaks of this insect, but is more general
than.any outbreak which has occurred in the last ten years.
Collections made in the vicinity of Chicago and at Urbana showed
a very small percentage of parasitism in the eggs.
FOREST TENT CAfTERPILLAR (Malacosoma pluvialis Dyar and M, disstria Huebn.)
Oregon Don C, Mote (March 5): The tent caterpillars, Malacosoma
luvialis and M, disstria, will probably be common but not
sensationally a1nridant this season, A partial survey of the
region thich was heavily infected last year yielded 160 egg
masses In about throe hou;s wi.Th four persons scouting. Although
alder and willow er e the major host plants, they contained
very few overwintering egg masses, following excessive
defoliation of last spring. Most of the egg rings were found on vine maple (Acer circinatgum which apparently had not been attacked the previous season, A microscopical examination of
the egg masses yielded the following data:
Caterpillars ........... 172
Undeveloped ............ 397
Egg parasites .......... 81
Total eggs examined 650

PIGEOI TREMEX (Tremex columba L.)
New York E. P. Felt and M. D. Leonard (December 6): Sugar maples in
Champlain, Chateaugay, Messena, Moira, and Bombay were all more or less badly affected with the pigeon horn-tail and
showed evidence of the work of the attending parasite Thalessa.
SUGAR-MAPLE BQRER (Glycobius specious Say)
New York E. P. Felt and M. D. Leonard (December 6,1923): Observed rather
commonly in Champlain, Chateaugay, Messena, Moira, and Bombay, New York. Many sugar maples in these towns are in a dying or
greatly weakened condition from the attacks of this pest.

Michigan R. H. Pettit (M1arch 10): The bdanv'eevils is gradually

and most of Michigan beretofore has been free from the
weevil. 'This fact Zz i' us to put on a campaign last fall
against this pest.
