• THE MORE IMPORTANT RECORDS FOR MARCH, 1934 
During the month reports of grasshoppers emerging were received 
from several places in the Northwest. These refer to the noneconornic 
species which passed the winter as nymphs. The economic species, so 
far as our records show, have not yet started to emerge in the North- 
west, although they were reported as emerging in large numbers late 
in the month in the Salt River Valley of Arizona. The winter through- 
out the Northwest has been especially mild and dry and there is .every 
indication that the grasshoppers have overwintered in large numbers. 
Severe winds in South Dakota have so badly blown the soil in some 
areas that eggs are exposed or buried so deep that there is but little 
chance of their hatching. However, despite these conditions there 
appear to be plenty of eggs to cause a very serious infestation. 
Mormon cricket outbreaks are expected on the Fort Hall Indian 
Reservation and near Idaho Falls in Idaho, and on the Crow Indian 
Reservation in Montana. A second infestation in Montana occurs west 
of the Crow Reservation and extends into the State of Wyoming. 
Over much of the territory infested by the Japanese beetle heavy 
snows in the period of extremely low temperatures during the past 
winter kept the soil temperature well above the lethal point for this 
insect and no unusual winter mortality is expected. 
Up to the middle of January the chinch bug had suffered only 5 
percent mortality in Indiana. By the end of March 3 percent winter 
mortality was recorded from Missouri, with similar low mortality re- 
ported from Kansas, Nebraska, and Iowa. The severe weather that pre- 
vailed during the last few days of the month, however, may have a 
decided effect upon the chinch bug populations in parts of the infested 
area. 
Reports from Indiana and Tennessee indicate that the hessian fly 
has passed the winter very successfully in that section, having 
suffered but 4 percent winter mortality, while reports from Kansas 
indicate that approximately 7 percent died during the winter months.
