THE MOPE IMPORTANT RECORDS FOP MARCH 
Grasshoppers were Beginning to hatch in the Palo Verde Valley of 
California during the second week in March. Overwintering nymphs of 
those grasshoppers which survive in the immature stage were observed 
in east-central Missouri. 
Mormon crickets began hatching in Nevada, Washington, and Oregon 
in March. 
The usual reports of cutworm damage to truck crops were received 
from the Southern and Southwestern States. 
Continued reports of low winter mortality of chinch bugs were re- 
ceived during March from Illinois, Missouri, and southwestern Oklahoma. 
Reports just reaching this office indicate a winter mortality of 50 
percent or over in the more northeastern infested counties in Iowa, 
from 10 to 40 percent in the southern and western counties of Iowa, and 
about 40 percent in southeastern Nebraska. In Oklahoma bugs started 
leaving winter quarters during the last week in the month. 
The brown wheat mite ( Tetrany china tritici Ewing) has been reported 
as very abundant in wheat fie Ids in southwestern Oklahoma end seriously 
damaging barley in addition to wheat. 
San Jose scale was materially reduced by the cold weather in Georgia. 
Adults of the plum curculio started leaving hibernation quarters 
in central Georgia on the 20th of March. 
Losses occasioned by pear thrips, somewhat heavier than normal, 
are reported from Lake County in California. Emergence of the adults 
began late in February; however, on the whole, injury is below normal. 
Following the severe January freeze in Florida new growth appeared 
during March on the citrus trees and a few green citrus aphids started 
to appear. The introduced Chinese ladybertles, however, failed to 
reappear up to the time of our most recent report. It is feared that 
these introduced predators have been destroyed.
