Of the 52 Counties cooperating in 1923 ever 90 per cent of the 
farmers in Aclasis, Appanoose, Boone, Carroll, Cass, Cedar, Dallas, 
Des Moines, Fremont, Guthrie, Henry, Jasper, Lucas, Mills, Monroe, 
Montgomery, Page, Polk, Pottawattamie, Taylor, ^apello, barren, and 
Wocdoury put off seeding until after the fly-free date was estab- 
lished. The flaxseed- count enabled us to predict accurately the 
fly-free date. 
The spring brood of flies began to emerge in the early seeded 
fields in April. Fred Eutcher, Extension Entomologist , is con- 
ducting a Hessian fly observation station at Emerson, Mills County, 
in order to determine the period of emergence of the spring brood. 
The dry and cold weather this spring killed a large number of flies 
in the flaxseed^:. The larvae pupated successfully but the adults 
died before creaking through the flaxseeds^ The percentage of 
dead forms is very large Out only a sm al 1 pvgrr certt of the larvae are 
parasitized. 
Missouri L. Has em an (May 22): The Hessian fly situation is not materially 
changed from the earlier report. Most farmers are centering their 
attention On the chinch bug in wheat, though we will have some 
Hessian fly damage undoubtedly. 
Nebraska M. H. Swenk (April 20-May 15): During the period covered by this 
report, adults of the Hessian fly have been emerging from the over- 
wintered flaxseeds. Examination of material on May 2 from Dodge 
County and en May 5 from Saunders County indicated that the great 
bulk of the flies had not as yet emerged. 
Kansas J. W. McColloch- (May 2): This report represents the damage to 
wheat last fail; 9,761,085 acres were sown to wheat in the fall of 
19 23 and 633,613 acres, or 6.5 per cent, show fly damage. Of the 
633,613 acres showing injury 128,481 acres, or 20.3 per cent, will 
be a complete failure. (May 2l) : The Hessian fly has not proved 
as serious this spring as was anticipated. This is probably due 
to the dry, cold soring which is holding everything back. The 
principle damage so far this spring has been reported in the eastern 
third of the Staxe. No damage has been reocrted from northwestern 
Kansas where the fly was so abundant last fall. 
Oklahoma E. E. Scholl (May 17): In the counties of Ottawa and Craig a 
number of wheat fields show such heavy Hessian fly damage that they 
will be plowed under and, at the suggestion of the county agent, such 
crops as cowpeas and soy beans will be planted. 
CHINCH BUG ( Blissus leucopterus Say) 
Illinois XI. P. Flint: The weather of the past month has been very cool and 
but little ep;g laying has taken place. The rainfall has oeen about 
normal but on the whole weather condixions have been unfavorable to 
this insect. They have not beer, sufficiently adverse to cause any 
great reduction in the number of ' chinch bug;s in fields.
