OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR AUGUST, 1929 
The Mediterranean fruit fly inspection during the month disclosed 
infestations on only seven properties. One of these, at Inverness, Citrus 
County, Drought in a county in which infestation had not previously been 
determined. During the month very few adults or larvae have been found 
even within the older centers of infestation. 
TJuring the late summer grasshoppers became generally destructive 
over the greater part of the East Central, -Vest Central, and North Central 
States with rather heavy damage in scattered localities throughout the re- 
gion of the Rocky Mountains and the Great Basin. 
Very heavy losses due to the depredations of v /ireworms on potatoes 
~nd ^rain have occurred in southwestern Idaho. In one single potato planta- 
tion the actual loss caused by reduction in grade due to wdreworm injury 
amounted to $125 per acre. 
A serious outbreak of the bertha armyworm, apparently more intense 
in the northeastern corner of the State, is reported from the northern 
third of North Dakota. 
A preliminary survey of the Hessian-fly situation in New York indi- 
cates that in the important wheat-growing counties the infestation is ex- 
tremely light, only about 1.3 per cent of the straws, on an average, being 
infested. 
The corn root worm is causing severe lodging of corn in many locali- 
ties in the East Central and West Central States. 
A report from Georgia indicates that the apple maggot was found for 
the first time in that Stnte in August. 
The oriental fruit moth is reported as generally serious from 
Connecticut southward to Georgia and westward to Illinois and Mississippi. 
In many parts of this region the percentages of infestation ran very high. 
Reports from the Bureau of Entomology's laboratory at Moorestown, N. J., 
indicated that parasitism in that district was running from 80 to 100 per 
cent. r
