L. Haseman (September 12): The fly situation continues threatening. 
Fanners are preparing wheat ground early with rains favoring this 
work. The Department of Entomology is making a drive on delaying 
seeding until the fly-free dace. Wo nope to handle threatening out- 
breaks with the cooperation of our growers. The infestation is less 
threatening across the central part of the State. 
Nebraska M. H. Swenk (September 1-15): At the Hessian fly observation sta- 
tion, established near Plattsmouth, Cass County, where the examination 
of 1,600 wheat plants showed an average infestation of 6.6 per plant, 
the insects began to emerge September 1 and were moving about in the 
fields in force by September 4. There was a heavy emergence from 
September 4 to 9, so that by the latter date over 40 percent of the 
flaxseeds in the stubble had given up their flies. Egg laying began 
on September 6, and on September 11, 1,660 eggs were laid on 100 
wheat plants. Emergence slowed up after September 9 and cool weather 
of the last few days has checked activity in the fields, but a heavy 
wave of emergence is looked for following the next few warm days.

Wisconsin A. A. Granovsky (September 15): This pest is rarely injurious in 
Ec or County* 
Missouri A. F. Satterthwait and R. A. BHanchard (September 4): Wheat around 
Pacific is very heavily infested by this pest, in some fields nearly 
100 per cent of the shoots being infested. Three fields were left 
uncut because of the damage done by this pest and Hessian fly together. 
A PENTATOMID (Chlorochroa opngirua Uhl.) 
Washington A. L. Me lander (September 7): Chloroch roa c pnerrua Uhl. was just 
sent in by one of cur former entomology students from Roberts, Idaho, 
with the following note en habits: "It is ruining about 10 per cent 
of the wheat c^cp here. It sticks its piercing mouth parts into 
the kernel cf wheat curing the milk stay;e and feeds, causing it to 
shrivel. They are very numerous near Mud Lake." 
WHF/T SAWFLY 30FFR (Ce phus pvgmaeus L.) 
New York G. E. Smith (July 14): This pest is very bad in wheat fields this 
year in Orleans County and is causing much heavier damage than the 
Hessiun fly. 
Wisconsin A. A. Granovsky (August 28): Practically all fields of wheat in 
Door County were slightly infested with wneat sa ,,r fly borers, but 
injury was rather slight. All injured plants dried before harvest- 
ing and the grain was not filled properly.
