THE MORE IMPORTANT RECORDS EOR JUNE 
The grasshopper situation siill remains severe over a large part of the 
West. Practically all Melanoplus mexicanus Sauss.. had reached the adult stage 
during the first week in June in the Imperial Valley of California and Arizona, 
and were starting to transform to adult in New Mexico and Colorado. In the 
northern Panhandle of Texas, southern Oklahoma, and Kansas about three-fourthb of 
M. mexicanus were in the nature stage during the second week of the month. Dur- 
ing the first week of the month ha,tching wa.s practically completed in Nebraska, 
Iov;a, Monta,na, Wyoming, and Utah. By the third week in the month hatching was 
practically completed in North Dakota, Minnesota, and Michigan, 
Up to the third week in June the lange bands of Mormon crickets in Big Horn 
and Yellowstone Counties, Mont,, were still at high elevations and are hot likely 
to migrate into crop areas, as the vegetation is abundant. The crickets one now 
largely in the adult sta.ge. In Utah and Idahio, although there vras some migration 
crops wore adequately protected by control meonures. The infestation in South 
Doicota is quite heav^,’’ in limited enoas and some crop damage is being reported 
from Nevada, 
Associated with the very delayed spring, severe cutworm injury to a wide 
variety of truck crops was reported from the North Central and East Central 
Sto.tes and in pa,rts of California. 
Heavy flights of moths of the beet webworn were observed in North Dakota and 
Utah and severe damage was being done by the larvae in parts of Washington State, 
Heavjr defoliation of ha,rdwood trees by Ma.y beetles v/as reported from the Middle 
Atlantic and East Central States, 
General reports of damage by the rose cha.fer v;cro reported from the New 
England, Middle Atlantic, and East Central Stales . 
During the third week in the month Japanese beetle started emergence in 
Delaware, District of Columbia, and Virginia. 
Serious crop damage by wireworms is reported from New England, Middle At- 
lantic, East Central, and North Central States, and from Idaho. 
No serious damage is expected from chinch bug in Ohio, Owing to rank, 
thick growth of vdaeat, the ovcrv/intcrcd adults migrated to corn to a. greater 
extent than usual. Wealher conditions unfa,vora,ble to chinch bug development 
very much reduced the small-grain infestations in Indiana and Illinois, Ralher 
severe infcstalions are reported from lov/a, Nebraska, Kansas, Missouri, and 
Oklahoma,
