OUTSTANDING skTOMOLOGICAL FEATURES IN THE UNITED STATES FOR JUNE, 1931 
<m<s severe armyworm outbreak reported from Texas as far northward as Vir- 
gir^a. In the last number of the Survey Bulletin became serious during the month 
_ June in the East Central States westward to Iowa. In the East Central 
States this insect is doing considerable damage to small grain and corn. 
The unusual cutworm prevalence that developed during May progressed 
through the early part of June, re-ports of serious damage to a great variety 
of crops having been received from Connecticut southward to Virginia and west- 
ward to Colorado and Utah. The most serious phase of this cutworm development 
is an outbreak of the variegated cutworm which extends from southern Nebraska 
across Kansas and into Oklahoma and Arkansas. 
During June grasshoppers developed to such an extent as to require con- 
trol measures in northwestern Minnesota, throughout the two Dakotas, southward 
through Nebraska to north central Texas, and westward into the Great Basin re- 
gion. There is a local outbreak in Klamath and Lake Counties, Oregon, where 
25,000 pounds of poisoned bran mash are being distributed daily for their con- 
trol. 
Wireworms have been reported as doing rather severe damage to corn in Fer- 
mont and Pennsylvania and to a variety of crops from New York southward to 
Maryland and westward to Iowa and Nebraska. The wireworm Keteroderes lauren- 
tii Guer. more seriously damaged the commercial Irish potato crop of Alabama 
than it has in any year since its discovery in that State. 
The Hessian fly is apparently decidedly on the increase in the East Cen- 
tral States, with scattered serious infestations in Nebraska and Kansas. Ra- 
ther heavy infestations of spring wheat by this insect are reported from the 
Willamette Valley of Oregon. 
A rather unusual infestation of wheat by the tenebrionid Blapstinus ^re- 
gal is Casey in the region north of Great Eplls in Montana occurred during the 
month. In the infested fields as many as 100 beetles to the square yard have 
been observed. 
During the last week in June recently hatched chinch bugs were observed 
in the heavily infested area extending from western Ohio to southeastern Kan- 
sas. The outbreak this year sec-ns to be more severe than has been recorded 
for several, years.
