Maryland

Summing up the results; of the Survey, we apparently will have 
very close to normal emergence of the Hessian fly this fall. That 
is, the main "brood will come out on about the average date. Appar- 
ently the brood will be rather well bunched and not scattered out 
as is the case in some years. There is likely to be a moderately 
heavy infestation in early- sown wheat in the eastern audi central 
parts of the State, with a light infestation in early-sown wheat 
in southern and western Illinois. The fly-free date will probably 
hold very close to those indicated on the enclosed map this year. 
The fly has caused very little damage in Illinois during the 
last few years, but it is in a good position to come back strong 
if early seeding is generally practiced in any section. 
C C. Hill and H. D. Smith (Augast 19)L The following table shows 
the percentage of wheat culms found infested with the Hessian Fly. 
The infestation was much lighter on the Eastern Shore than in west- 
ern Maryland. The average county infestation for the State was 12 
per cent as compared with 3 per cent infestation found in 1925 and 
1925. Occasional wheat fields in western Maryland showed consider- 
able damage from the fly, and these may he a source of heavy infes- 
tation for the coming season.

C. Wakelancl (July 29): False wireworms have destroyed many acres 
of wheat in the dry farming areas of eastern Idaho this season. 
Several of the farmers are planning a poisoning campaign against 
the beetles this fall.
