摘　　要：柳乌蠹蛾是吉林省西部阔叶树的主要蛀干害虫之一,严重影响木材质量。该虫以幼虫越冬,在白城市区2a1代,成虫羽化盛期为6月22日至7月15日,卵期14～24d,孵化率较低,成虫趋光性较强。可用黑光灯诱杀成虫;也可用40%乐果乳油加柴油(1 9)或50%杀螟松乳油点涂虫孔,杀虫率达100%。Holcocerus vicarius, as a primary stem borer in western Jilin Province, which affects timber quality seriously. The results of observing experiment there showed that it overwinters as a larva, has one generation in two year; the high time for adult eclosion are June 22 to July 15 every year (14d to 24d). Its hatching rate is lower relatively and adult phototaxis is better. The control rate is up to 100% when using 40% omethoate appended diesel oil (1:9) or 50%fenitrothion by painting drop to the galleries.
