HESSIAN FLY ( Fhytonhaga das true tor Say) 
Nesbraska M„ H„ Swank (June 15). "Local losses, due to the attack 
of the Hessian fly, have become apparent as harvest 
approaches. Early in June considsrable wheat in north- 
western Furnas County began to show results of injury 
"by this pest. S^airo nation shewed about 10 p3r cent 
infestation. In western Seward County much of the wheat 
has "been injured noticeably, some cases to the extent 
of half the crop,, Seme early sewn fields in southern 
Saunders County were going down badly by the middle of 
Juno, by which time reports of serious injury were also 
being received from Lodge Coimty. The cool, backward 
spring has favored Hassian f]y development and in many 
•v*-sv»cns this pest is an actual menace to the grain to be 
sowed, this fall." 
Kansas E. G-. Kelly (June 16), "A very light infestation occurs 
oyer, the eastern third of . the State." 
J. W. McColloch (June 20). ,r While very little infestation 
by the fly could be found during early spring there has 
been a mirked increase in the appearance of the S3Cond 
brood. In some cas3s as high as 25 per cent of the stalks 
are going down. It is of particular interest to note 
that infested wheat was received from Cheyenne County in 
northwestern Kansas. This is the first time the fly 
has bden taken in this County, our previous western limit 
being in the northeastern corner of Logan County, This 
means that practically the entire acreage devoted to 
wheat in this State is subject to outbreaks of the Hessian 
ny. 1 .' 
Oregon L. P. Rockwood (June 13). "Infestation severe over a 
limited area in the Pleasant Hill section of Lane County 
and at Independence in Polk County. As a rule this 
season the earlier sown fall wheat is less infested than 
late-sown fall wheat, probably because the former made 
better growth before the advent of the unusually long 
dormant season. There are no signs of the s3Cond spring 
brood as yet."
