THE MORE IMPORTANT RECORDS FOR JUNE I93U 
The dry weather that prevailed during late May and well through June aggra- 
vated the grasshopper situation. In general the sections of heavy emergence coin- 
cided with those indicated "by surveys conducted last fall in certain States. Ho 
surveys were made in Wisconsin and Michigan and there the situation is much worse 
than was anticipated. Over 7^,000 tons of poisoned "bait purchased under a special 
appropriation has "been alloted to the States, most of it going to generally in- 
fested territory. 
During June the intensity of chinch "bug damage increased greatly, the bugs 
leaving the snail grains and in certain sections damaging corn "before barrier 
materials become available. The unusual weather conditions caused the bugs to 
mature to the adult stage earlier than usual. In the cooperative campaign for 
chinch bug control carried on under special appropriation more than 1,250,000 
gallons of creosote was allotted to Illinois, over 2,000,000 gallons to Iowa, arL 
almost 2,000,000 gallons to Missouri. Lesser amounts were allotted to other States 
in the infested area. In some States the allotments from the special appropria- 
tion were augmented by purchases made with funds supplied by FERA. 
Outbreaks of the mormon cricket in Montana and Idaho were longer and did more 
damage than was anticipated. 
The rose chafer is reported as more seriously abundant than it has been for 
many years in the New England and Middle Atlantic States, the infestations extend- 
ing westward into Michigan and Indiana. 
Flea beetles, attacking corn principally, have been very destructive this year 
in Indiana, Illinois. Michigan, and Wisconsin. 
The plum curculio emerged so late that little dar.ia.re is anticipated from the 
second brood, with the possible exception of injury to Elberta peaches in the Fort 
Valley district of Georgia. 
Heavy damage by the beet leafhopper is reported from the Twin Falls district 
in Idaho and the Sevier Valley in Utah. 
The fall canker worm is reported as unusually abundant in the eastern pert of 
New England and in New York. 
The spring canker worm is reported as abundant from New York westward through 
Ohio and Michigan to Nebraska. 
The elm leaf beetle is now well distributed over the Boise and Payette Vallevs 
of Idaho, and is seriously defoliating shade trees. ■ 
Losses of cattle from attack by the screw worm are being reported from Florida 
and Georgia, indicating the possibility of a repetition of last year's serious out- 
break of this pest.
