Different temperatures affect the effect of controlling pine caterpillars, Dendrolimus punctatus, by B.t pesticide *** using B.t pesticide,the mortality of *** decreased as the temperature *** the result of 4 temperature gradient tests,it was showed that 20 ℃ is the threshold that determine the effect of controlling *** by B.t. The results shows that different temperatures affect the feeding deterrence of the B.t to the *** larvae also,but in the all temperature treatments,the feeding deterrences are apparent consistently.
