Montana 
J. R. Parker (March 24): This insect is preset in Wibaux, Rich- 
land, Dawson-, and Roosevelt Counties. Very little field work has 
been done in regard to ascertaining the intensity of the infesta- 
tion hut according to the County Agents the number of stems infest- 
ed with "flaxseeds" in some fields runs as high as 30 per cent. 
Personally I have only been in a few fields and these had already 
been harvested. However, the number of dwarfed stems and the 
large number of "flaxseeds" in each of these dwarfed stems lead 
me to believe that the infestation had been very heavy. Unless 
weather conditions interfere, I expect we will have serious trouble 
with the Kessian fly in Montana this year.
