INSECT PEST SURVEY BULLETIN

OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR JULY, 1923. 
The very unusual insect conditions recorded last month continued through 
July. 
Grasshoppers are still attracting major attention throughout the Mississ- 
ippi Valley and the Rocky Mountain and the Pacific Coast regions, the trouble 
extending into the Ohio Fiver Basin and the Great Lakes region. In addition 
to the States reported as being seriously infested with grasshoppers during 
June, Indiana, South Dakota, Montana, Minnesota, and Nevada were reported in 
July. In addition to the grasshopper troubles, Utah reports a serious outlook 
for trouble with the Mormon cricket in the Uinta Valley, one band of these 
hoppers being 3 miles wide and several times as long. 
The alfalfa weevil is established in Sierra County, California. 
The Hessian fly infestation throughout the Middle Atlantic States and 
the Ohio Basin continues Delow normal, except in New York State, while in the 
Upper Mississippi Valley the situation is reported as serious in Wisconsin, 
Missouri, Nebraska, Kansas, and Iowa, and the pest is apparently on the increase 
in Minnesota and North Dakota. 
The greater wheat-stem maggot is materially affecting the crop in Missouri, 
North Dakota, Nebraska, and Oregon. 
The chinch bug infestation is now becoming serious north of the region 
reported last month. Reports of infestations are coming from southern Michigan, 
southeastern Iowa, and South Dakota. In Missouri calcium cyanid is proving an 
excellent material for use in chinch bug barriers. 
The stalk borer is rather generally reported from New England, the Middle 
Atlantic States, the Ohio River Valley, westward to South Dakota, and southward 
to Missouri, 
♦ The garden webworm, both as a truck and as a field crop pest, is reported 
from Missouri and Kansas. In Kansas some farmers report a total loss of the 
second cutting of alfalfa. 
The apple tent caterpillar was generally abundant over New England and 
the Middle Atlantic States, with severe infestations also reported from Wisconsin. 
An interesting note has been received from Michigan to the effect that 
the anthicid beetle Notoxus talpa has been riddling the fruit of sweet cherries 
at Niles .
