INSECT PEST SURVEY BULLETIN 
Vol. 10 September 1, 1930 No. 7 
OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR AUGUST, 1930 
The serious grasshopper conditions reported in the last number of 
the Bulletin continued during August, and particularly serious outbreaks 
occurred in Idaho and northern Utah. 
The pale '.restern cutworm was'' reported as locally serious in Utah, 
and the Bertha armyworra v;as reported in outbreak numbers in the north- 
eastern corner of North Dakota during August. 
The periodical outbreak of the white-lined sphinx reported from 
Nevada in the last number of the Survey Bulletin extended westward into 
the Lake Tahoe region of California. 
The dry-leather conditions of July extended through August and, 
as ras to be expected, damage by the red spider continued throughout 
the month. 
In this number of the Survey Bulletin is a summary of the Hessian 
fly survey of New York State. The infestation as a whole is light, 
averaging for the State 3.7 per cent. In southeastern Nebraska about 
80 per cent of the puparia were dead by the last of July, largely 
as a result of the hot, dry weather. 
The fall armyuorm continued its depredations during August through- 
out the Gulf Region. 
Very severe damage by several species of corn root worms is re- 
ported from southwestern Nebraska; Diabrotica virgifera Lee. was the 
most destructive species. A species heretofore of practically no economic 
importance, D. filicorni s Horn.wgas also seriously numerous. 
The velvetbean caterpillar is again appearing in parts of Louisiana, 
although not so numerously as in 1929.
