GENERAL FEEDERS 
GRilSS HOPPERS (AcridTdae) 
General. W, E. Dove (April 22): Hatching of economic species has begun in 
Arizona, California, Texas, New Mexico, and Oklahoma. A severe outbreak 
of Melanoplus devastator Scudd. in the San Joaquin Valley of California is 
reported and intensive control operations were started during this week. 
Reports of threatening infestations received from the Yuma Valley, Ariz. 
Hatching of Dissosteira longipennis. Thos. reported to have begun in New 
Mexico on April 21. Control operations in this area expected to begin on 
April 25 . Although hatching of nonmigratory species in northern Texas and 
southwestern Oklahoma is reported, control operations probably will not be- 
gin before the first of May. A very small hatch reported in Utah. Results 
of survey examinations show the extent of paras it izat ion and predatorization 
to remain practically the same as reported last fall. Reduction in numbers 
of egg pods by natural factors during the winter months is negligible. 
Florida, J. R. Watson (April 22): Heavy infestation of Roroalea microptera Beauv. 
on narcissus in Clay County. Young observed migrating to narcissus fields 
from a distance of several hundred feet. Only third-stage observed on April 
l4, Adults observed' on April 17 in the southern part of Dade County. 
Michigan. R. Hutson (April 22): Surveys during the last week in Antrim, 
Charlevoix, Kalkaska, and Ogemaw Counties, in the northern part of the 
Southern Peninsula, indicate that grasshopper hatching has not yet started 
in the main infested areas; however, inspection of eggs reveals that devel- 
opment has progressed to a point where warm weather causes hatching. 
North Dakota. J. A, Munro (April 24): Usual reports of overwintered adult and 
nymphal forms. No hatching of M, mexicanus Sauss. or other economic species 
observed. 
South Dakota. H. C. Severin (April 24); Eggs had not hatched by April 21. Red 
mites very active in areas where eggs are abundant; carabid larvae also 
active. 
Oklahoma. C, F, Stiles (April 24): Reported as hatching in large numbers in 
Jefferson County. In a few localities young hoppers found present at the 
rate of 80 per square yard in pasture land in the northern part of Jefferson 
County and 30 per square yard in the southern part. Crop hoppers, perhaps 
M* b ivit tatus Say or M, different ialis Thos., reported as high as 35 per 
square yard in the southeastern part of Lincoln County. 
Montana. H. B. Mills (April 24); Overwintering grasshopper nymphs have been re- 
ported as appearing in considerable numbers in various parts of the State 
but to date there have been no verifications of eggs hatching in crops. 
Utah. G. F. Knowlton and F. C. Harmston (April 8): Nymphs reported as hatching 
out m alfalfa fields at Greenriver, Emery County, and on warm southern 
slopes m some localities in Box Elder, Tooele, and Utah Counties. 
Nevada. _ G. G. Schweis (April 24): Reports filtering in that M. mexicanus is 
hatching in great numbers in Churchill, Washoe, and Lyon Counties. Control 
measures will be started at once.
