M. H. Swenk (March. 22): Hessian flies are moderately 
to very a'oundant. paring the last week in October and ea.rly 
in November the winter wheat in Phelps and adjacent counties 
developed a serious infestation. This infestation includes 
the whole of Phelps County, and extends northward over western 
and northern Buffalo County, eastward, into Kearney Cou-nty, 
southward into northern Harlan County and Pranlclin County, and 
westward into Gosper County (see my report of December 1). 
At the same time, wliat appeared at first to he a much less 
important infestation was found in Seward and Tliayer Comities. 
Later, however, it was found that this more eastern area of 
infestation extended over much of Butler, Seward, Saline, 
Fillmore, Tliayer, Jefferson, and Gage Counties, and also 
extended somewhat into adjacent counties. Waeat- in this more 
eastern area th^t looked all right when the HoVemher snows 
covered the fields was brown and dead when the late January 
thaws exposed the plants, and manj'- showed a heavy infestation 
with puparia. These infestations developed as a result of a 
much delayed emergence of the main fall brood, due to the hot 
dry conditions of September and October. The present situation 
points to the probabilitj'' of extensive. se.ri.ou.s damage this 
spring.
