摘要
根据雪毒蛾StilpnotiasalicisLinnaeus幼虫下树越冬,出蛰后经树干上树为害的活动特点,采用树干束草诱杀或选择强触杀性农药喷干的方法,进行早期防治,同时研究出杨树不同径级条件下的越冬代幼虫防治指标为116x—358(诱集头/株)。
Stilpnotia salicis larva has the movable character of overwintering under the hosted trees and feeding on the trees after hybernation,so on the trunk straw-tying is used to attracting or high contact poisoning pesticides used to spray for larva’s early control.It is found that the control threshold of the overwintering larva under different diameters is 116x-356(attracting number/ per zhu ).
