because of the fact that the infested culms are the smaller, 
later, weaker ones which would never malce heads in any case; 
Judging by present indication, the fly is practically all in 
the full-grown larval or flaxseed stage. All wheat is in a 
poor condition owing to the very dry weather. Only 0.22 inch 
of rain has fallen at Urbana during iviay. 
C. J. Drake (May 7): The Hessian fly has been greatly reduced 
in numbers and it is very hard to find specimens in wheat fields. 
Over 90 per cent of the fanners in the winter- wheat- growing sec- 
tion of the State cooperated in the Hessian fly campaign last 
year. 
M. H. Swenk (April): An inquiry into conditions in Johnson and 
Pawnee Counties, made during the present month, showed that while 
there was considerable Hessian fly in volunteer wheat plants and 
in drilled wheat sown considerably before the announced dates of 
safe sowing, the wheat sown on or after the announced date of safe 
sowing is practically uninf ested. 
J. W. McColloch (May 21): Reports and surveys show that the 
Hessian fly is present in damaging numbers throughout nearly all 
the wheat- growing area of the State. Thousands of acres of wheat 
have been plowed under. The second spring brood is just beginn- 
ing to emerge and further damage is anticipated before harvest. 
In many ways the present outbreak has been more destructive than 
any previous one. 
WIKEWOSMS ( Elateridae ) 
Claude lakeland (April 30): A toll of hundreds of acres of wheat 
has already been exacted by wireworms in the irrigated sections. 
Wireworm injury is so severe this season that we are planning mak- 
ing an extensive survey of Canyon County. 
FALSE WJBES70BLIS (E lsodes spp. ) 
Claude Wakeland (April 30): The false wireworms are proving very 
destructive to fall and spring planted grain in the dry-farming 
areas of eastern Idaho. 
TJHEAT STRAWOELI ( Harmolita grand is Piley) 
J. W. :.icColloch (May 21 ): Samples of wheat infested by the straw- 
worm have been received from Great Bend and Greenburg. 
A HOOT APHID (Geoica snuamosa Hart) 
Nebraska 
M. H. Srenk (April): During the first week in April the wh£at- 
root aphid, Geoica squamosa , was found so abundantly on the roots 
of smartweed in a stubble field in Nuckolls County that the ques- 
tion was raised as to whether it would' be safe to plant corn in 
that field this spring.
