CEREAL AND FORAGE-CROP INSECTS 
WHEAT 
HESSIAN FLY ( Phytophaga destructor Say) 
Illinois W. P. Flint (October 20) . "The fly-free date will apparently hold 
good throughout the State with the exception of a very slight infesta- 
tion in northern Illinois; here wheat should be sown a day or two 
after the advised seeding date." 
Kansas J. W. McColloch (September 27). "Fall emergence began in Riley and 
Wabaunsee Counties about September 21. Eggs are numerous on volunteer 
wheat. Wheat planting is well under way. An examination of many 
fields of volunteer wheat in central Kansas on September 26 showed 
a general light infestation. In the southern part of Saline County 
eggs were hatching." 
A FALSE WIRFWORM (Eleodes opaca S ay) 
Nebraska M. H. Swenk (October l) . "Hundreds of acres of unsprcuted winter 
wheat have been destroyed by this pest during the present month in 
the vicinity of Big Spring, Deuel County, while lying in the dry coil." 
Kansas J. W. McColloch (September 27). "The weather has been dry and hot. 
Wheat planting is under way but the soil is dry and germination is 
slow." (October 20 ) "The abundance of this pest in the western 
part of the State has greatly increased. The fall has been dry and 
seed has been in the ground from three to five weeks without germinat- 
ing. At Sublette worms have taken whole fields; at Selden worms are 
thick in thousands of acres; in many fields in Greeley and Wichita 
Counties the damage ranges from 40 to 75 per cent. At Lioeral on 
October 9th it was estimated that 50 per cent of the wheat was taken, 
and at Plains the farmers stopped drilling." 
Oklahoma J. W. McColloch (October 20/ . "We have reports of this insect from 
Tyrone, Ckika., in which it is stated that injury is occurring through- 
out the northwestern part of that State." 
WIRE770RTS (Phcletes sp.) 
North Dakota C. N. Ainslio (May 22). "In a field of young wheat, just across the 
road from a cornfield at Beach, N. Dak., I took within a minute or 
two about a dozen specimens of a slender gray elateri£ that I had 
never seen previously. These were, apparently, congregated within 
a small area, for further search produced no more of their; in the 
vicinity."
