In eastern Nemaha, eastern Richardson, and western Thayer 
Counties the infestation ran from 25 to 50 p^-r cent. In- 
festations of less than 25 per cent were found in Sarpy, 
Douglas, central Dodge, southern Colfax, southern Platte, 
and eastern Nance Counties, and, farther westward, in 
Phelps (a general infestation) and Redwillow Counties. 
Ey May 28 about 75 per cent of the larvae had entered 
the puparimn stage, and by June 10 adult flies of the 
supplementary spring brood were emerging over a large 
area. The intensity of this emergence varied greatly. 
In southern Saunders County, fields were found in which as high 
as 60 per cent of the spring-brood puparia had given up 
their flies by June 16. In Lancaster County north of 
Lincoln -bout 22 per cent of the spring-brood puparia were 
empty by June 18, while south of Lincoln about 20 per cent 
had emerged by that date. The late occurrence of the larvae 
of the supplementary spring brood and the early ripening 
of t v e wheat, however, prevented this brood from doing a 
great deal of damage to 'the crop. 
Now (July 17) •• that all of the wheat in southeastern 
Nebraska has been cut. it is possible to report upon the 
general effect of the above infestation on the yield of 
grain :.n this section. Fields with an infestation of from 
75 to 10Q per. cent, mostly early-sown fields, that were 
not badly enough injured to justify being plowed up during 
the '.ast . "n dry 3 :• n May, show a redaction of about one- 
third from the normal yield. General corj-i'ior.s for the 
growth of the wheat were so favorable, however, that this 
.reduction of yield in the heavier infested fields is not 
obvious in the general average yield of all fields in the 
affected counties, which will be about 19-i bushels to the 
acre, decidedly above the average yield for this section. 
R. L. '.Vebster (July 2): Infested wheat plants were sent 
in from Mossyrock in eastern Lewis County under date of 
June 21.

"Flaxseeds" of f irst generation were found Api'il 25 about 
two weeks earlier than usual. Infest~tion of winter wheat 
and early spring-sown wheat by the first spring brood is 
heavier than normal in 7.\?shing-:on and Yamhill Counties.
