THE MORE IMPORTANT RECORPS EOR JULY I934 
The grasshopper situation in th<» Great Plains remains unchanged. 
The hoppers are rapidly maturing and egg laying is taking place. Control 
measures will be continued throughout August over much of the territory. 
The outbreak in Wisconsin is reported as being the worst that has ever 
occurred in that State. In most of the infested area the campaign for 
the control of these insects has reduced damage to a low figure. 
Turing the month there was a general outbreak of sod webworms over 
northern Indiana, central and north-central Illinois, and eastern Nebraska. 
Red spiders are reported as doing unusual damage to a variety of 
plants. Reports indicate that because of the dry weather they are trouble- 
some from Connecticut to Maryland, westward to Kansas, and southward to the 
Gulf. They are also occasioning considerable trouble in Kern and Los 
Angeles Counties, California. 
The first of the annual wheat surveys to be reported indicates that 
the hessian fly infestation in Ohio was more than twice as severe as it 
was last year. Infestation was also severe in east-central Indiana. 
A serious outbreak of the black grain-stem sawfly developed in 
western Pennsylvania and eastern Ohio. 
Puring the month .first-brood chinch bugs matured and flights were re- 
ported from all parts of the infested territory. Good growing weather in 
the Ohio River Volley materially improved corn-growing conditions, despite 
chinch bug damage. 
Corn ear worm damage is reported from practically the entire United 
States. In the East Central States it was more abundant than it has been 
in several years, particularly j. n the fruit of tomatoes. 
Reports from Nevada rnd California indicate that in general injury 
by the alfalfa weevil was less severe than last year. 
This year the cotton leaf worm was first reported from Mississippi on 
July 26, early enough for broods of moths to develop, fly northward, and 
damage late fruit in the northern States.
