Ohio 
HESSIAN ELY ( Phytorhaga destructor Say) 
T. H. Parks (October 25): Nearly all eggs were hatched "by 
October 25 and the newly emerged larvae were found attached 
to the stalk under the leaf- sheath. Infestation exists at 
Columbus in wheat sown immediately after the recognized fly- 
free date. October was warm and late-sown wheat is getting 
a good start, The majority of the fields are free from in- 
festation. In this part of Ohio practically no wheat was 
sown before the safe sowing dates.

C. M. Packard (October 5): Volunteer wheat from Logansport 
to Evansville has 50 to 75 per cent of the stems infested. 
The fly is largely in the flaxseed stage, with about 15 per 
cent pupating. A few eggs and some newly hatched larvae are 
present. Volunteer wheat is not very abundant. Not much 
sown wheat was above ground by the last of September. 
W. P. Flint (October 24): An unusually heavy emergence oc- 
curred late in September. In many of the counties lightly in- 
fested at the time .of stubble survey, the fly is now numerous 
enough to lay large numbers of eggs on volunteer and early- 
sown wheat. From the information at hand, wheat sown on the 
recommended fly-free dates has escaped any serious infestation. 
J. H. Bigger (October 13): Adults were numerous the last 
week in September extending to about October 7 and 8. Exami- 
nations on October 9 and 10 show: 
Four fields seeded before October 2 60.4 per cent 
with eggs 
Two fields seeded after October 7 7.5 per cent 
with eggs
