storage during the winter months and have. multiplied to the propor— 
tions of a pest. This year a.close check hes been kept on their =) 
numbers. There has been no evidence as yet of mites attacking lar-— 
vae but they do »sresent a potential menace. Of the various methods 
that have beem tried for keeping the mite populaticn down, the most 
successful so far has been the occasional] exposure of the insect 
material to out-dzor conditions. The best time for such exposures 
is when the temperature is below 50° F., with a strong wind blowing. 
Under such conditisns mites usually disappear ufter 2 days. Our 
stock has had one such exposure this winter, and the mites are at. 
present very scarce."
