摘　　要：在落叶松人工林内利用落叶松绶尺蠖核型多角体病毒（ＺｒＮＰＶ）对落叶松绶尺蠖２、３、４龄幼虫进行了防治。使用浓度为１０３×１０７ＰＩＢ／ｍＬ的防治效果：２龄幼虫校正死亡率为７３．５３％；４龄幼虫校正死亡率为６７．５１％。使用浓度为１．０３×１０８ＰＩＢ／ｍＬ的防治效果：２龄虫校正死亡率为９０．８１％；３龄幼虫校正死亡率为８９．４７％；４龄幼虫校正死亡率为８６．４９％。同时证明落叶松绶尺蠖幼虫的龄期越小其死亡率越高、致死时间越短．防治的最适虫龄以２或３龄幼虫为佳。ZrNPV was used to control the 2nd. 3rd. and 4th instar larvae of Zethenia rufescentaria Motsch. in larch plantation. The corrective mortalities of the 2nd and 4th were 73. 53% and 67. 51% respectively with the concentration of 1. 03×107 PIB/mL. The mortalities of the 2nd. 3rd and 4th instar larvae were 90. 81%、89. 47%, and 86. 49% respectively with the concentration of 1. 03×108 PIB/mL.We also identified that the mortality increase and the fatal time decrease with the decreasing of instar. and the most suitable instar for controlling are the 2nd and 3rd instar larvae.
