摘 要:
The routine control method for Coleophora laricella is presented.i.e.in the peak period of eclosion and before oviposition of adults which can be killed by fumigation action of insecticidal smokes. But this method has some weakness as follows: The time of effective control is very short; control opportunities for different stands are not identical; control effects on large-area are not well; the effective rate of the insecticidal smokes is rather low when it be used once for all. Aforementioned weakness can be overcome in over wintering of larvae and good effects can be obtained.
