THE MORE IMPORTANT RECORDS FOR MAY 
During the last week in the month grasshopper hatching was generally 
under way on the Great Plains and in the upper Mississippi Valley. In the 
East Central States hatching had "begun hut was decidedly retarded by cool 
wet weather. In general, these insects are numerous enough to cause con- 
siderable trouble this year. 
Mormon crickets in many places are migrating from the egg beds and 
are reported as decidedly more abundant than last year over the greater 
part of the infested territory from South Dakota,, to Idaho and Utah. 
Damage by wireworms is recorded over a wide territory from Connect- 
icut to the Carolinas and westward to California. The outbreaks, however, 
are scattered. 
The curculio Naupactus leucoloma Boh. , which was discovered for the 
first time in the United States in Okaloosa County, Fla.,last year, is 
again active. The insect is attacking a wide variety of cro;ps, including 
velvetbeans, peanuts, corn, and cotton. In some fields three- fourths of 
the corn plants have been destroyed. 
May beetles began to emerge during the latter half of the month. 
Heavy flights were recorded in the South Atlantic States and in Kentucky, 
with instances of complete defoliation. The white grubs were reported as 
doing considerable damage to pastures in parts of Minnesota. 
Cutworms are generally abundant and destructive. Considerable damage 
in the East Central States was co,used by climbing cutworms. 
A heavy armyworn outbreak is under way in the Mississippi Valley.
