Comparative populations hibernating in surface-ground trash are given in 
table 11. On November 29 there were approximately five times as many weevils 
in hibernation in the untreated area as in the area treated with 0.5 pound of 
methyl parathion per acre on September 28 and October 10, 18, and 27. However, 
fall treatment did not eliminate these hibernating populations.
