OUTSTANDING- ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR AUGUST, 1924 
In this number of the Survey Bulletin is a summary of the Hessian fly summer 
survey from New York State. This indicates a general, reduction of infestation 
throughout the wheat growing section of the State, the infestation in 1923 averag- 
ing 8.5 per cent, while this. year it average's "but 6.4 per cent. In Ohio the infes- 
tation has increased 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, ; North Dakota and Kansas. 
The chinch hug situation remains about the same as last month throughout the 
greater part of the chinch bug belt. 
The corn earworm is again appearing in New England. The last outbreak in this 
region occurred two years ago. 
The fall army-norm has already appeared in Kentucky and is doing considerable 
damage. This early appearance may be the fore-runner of a more general outbreak 
later in the season. 
The western corn rootworm is reported as 'seriously infesting corn in Missouri 
and Kansas. The beetles are now cutting the silk. 
The Conchuela (Ohlorochroa ligata Say) is reported as doing immense damage to 
the seed crop of alfalfa in the Fort Stockton and Pecos sections of Texas. 
Late in July and. early in August the green apple aphid was reported as becoming 
seriously abundant . throughout the apiole- growing section of New York State. 
The variety of the coiling moth known as Car^o c aosa opmonella simwsonii Busck 
was reared for the first time in the Yakima region of Washington State. Side worm 
injury ~by the codling moth is reported as more serious than usual in New England 
and eastern New York, .while in western New Yoik the damage is not as serious as 
last year. 
The apple and thorn skeletonizer Is. now- generally distributed in New England 
and New York State. In Massachusetts it' was serious enough to occasion a special 
spray; in New York State, as a whole., the insect was less serious than usual. 
The painted lady butterfly was reported during the last week in July and the 
first week in August in unusual numbers in Wisconsin and South Dakota. This is 
practically the termination of the unusual development of this insect throughout 
the entire western and central United States, and Mexico. 
During the past month the potato leafhopper has been rapidly increasing in 
Indiana* Some fields, in the west-central part of the State, have been killed.
