INSECT PEST SURVEY BULLETIN 
V0I.3 September 1,1923 No *6 
OUT ST AID BIG ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR AUGUST ,1923- 
In this number osf the Insect Pest Survey Bulletin statistics on the 
summer Hessian fly surveys of New York State and Ohio are reviewed. The 
situation is reported as generally favorable in the Ohio River Valley, while 
the infestation in New York State is over 7 per cent higher than last year. 
In North Dakota very heavy infestations were observed throughout Golden 
Valley County, while in Nebraska this insect is present in the stubble in 
below normal numbers. 
The chinch bug situation in Ohio is very favorable, the pest being 
very much less numerous than last year. Serious local damage occurred in 
southern, central, and north-central Illinois, and a very serious movement 
of the chinch bug was observed late in July in coutheastern South Dakota, vhile 
both southeastern and northeastern portions of Nebraska are experiencing 
rather heavy chinch bug damage. 
The corn earwora, though not as serious as in 1921, is generally 
prevalent over the eastern States. In the Ohio River Basin, especially in 
southern Illinois and Indiana this pest has done quite serious damage to 
tomatoes, while in Georgia this pest is doing even more damage to cotton than 
the boll weevil in some of the northern counties. 
The stalk borer is unusually prevalent throughout New England, the 
Ohio River Basin, and the Upper Mississippi Valley, damaging a great variety 
of plants, particularly corn and herbaceous flowers, dahlias and zinnias being 
most seriously damaged. 
The garden webworm continued throughout August to be a serious pest 
to alfalfa in the Mississippi River Valley from Nebraska southward to Texas, 
Midsummer reports on the cotton boll weevil are reviewed in this 
number of the Bulletin. About 30 per cent of the total number of reports 
received from the cotton belt indicate heavy damage by this pest. 
The cotton leafworra appeared about two weeks earlier than usual 
throughout the northern part of the cotton zone, while on the other hand the 
cotton crop was about 10 days late in its development. Owing to these 
conditions rather serious injury by the puncturing of the bolls is reported from 
the greater part of the upper cotton zone. 
The apple and thorn skeletonizer is appearing in a most unusual 
epidemic throughout New England and southward to New York and New Jersey. In 
New England it is reported as having skeletonized fruit trees to such an 
extent that the damage is easily observable in passing along the railroads 
or highways. It is reported about the middle of August for the first time 
time in northern New Jersey. 
The fall webworm is also occurring in unusual abundance throughout 
New England and the Ohio River Valley,
