General. E, L. Shotwell (May 1){ ‘ Dissosteira longip^iinis Thos* 'began' 
hatching April 11 ip the Dunlap area; New Mexico., and on April 24 
were 90“percent hatched in this area. Populations averaged 500 per 
> square yard and little migration from the original egg beds had 
occurred at this date. The average hatch for. New Me?cico on 
April 23 was estimated as being less tiaan 5 pei’capt. Melanoplus 
mexicanus Sauss. and other crop grasshoppers began hatching in the 
Oklahoroa-Texas Panhandle area by April l4* On April 2S, a"bout 
15 percent had hatched, with populations averaging 15 per square 
yard in the heavier infested areas* About 80 percent of the grase-~ 
hoppers hatched in this area proved to* be M, mexicanus . In Colorado, 
M, bivltattus Say and M. mexicanus were reported as beginning to 
hatch in Morgan County on April 29* In western Kansas, Aeoloplus 
turnbullii Thos, and Aulocara elliotti Thos. reported as beginning 
to hatch in Meade County on April .25* *-i;« turo'btillii formed 90 
percent of the population in the hatch so far. As to the rest of 
the area-- Nebraska, North Dakota, South Dakota, Minnesota, Montana, 
and Wyomingir-no hatching has taken place as yet. Melanoplus 
confusus Scudd, was noticed to be in the first and " sec ond instar s 
on the 21st of April in Beadle County, S. Dak, Spring egg sur- 
veys in eastern South Dakota have shown severe infestations of 
Melanoplus differentialis Thos, and M, bivittatus along fence 
rows and roadsides at the ratio of 60 percent M, differentialis 
and 40 percent bivittatus . The eggs of M. differentialis were 
still in the coagulated stage of development, which will not 
permit hatching before June 1, M, bivittatus will not hatch before 
May 15. . In north-central Montana, a cross section egg survey of 
Hill County was made April 27. The results, as to the numbers 
of pods, checked with the fall egg survey. The writer has never 
before experienced such a uniform, high count of egg pods for 
an entire county. They are all in good shape and are in every 
stubble field examined. In some adjacent rangeland used for 
pasture, egg pods were found in wind-blown hummocks around the 
sagebrush. On old reverted land, clumps of grama grass sod 
averaged 0,5 pods per clump. Most of the M. mexicanus eggs are 
in the eye spot or early segmented stages. This precludes 
any hatching before May 15«
