摘要
梨星毛虫是梨树上的一种重要食叶类害虫。室内观察发现,梨星毛虫成虫寿命为7~13 d,成虫的求偶交配行为多发生在羽化后第2天,呈“一”字形交配,交配后平均7.17 h即可产卵;梨星毛虫日活动有2个峰期,高峰期主要发生于15:00-18:00,其次为7:00-9:00;其平均交配时长为7.89±4.23 h,从1.80~19.67 h变化不等。探索梨星毛虫的日活动规律和交配特点,有助于了解其生物学特点并为防治做指导。
Illiberis pruni is one of an important defoliating insects on pear trees.Laboratory studies found that the lifespan of Illiberis pruni was 7~13 days.The mating behavior mostly occurred on the second day after emergence,and the mating behavior in shape of Chinese characters of one.The pre-mating time was 7.17 hours.There were two peak periods in the daily activity of Illiberis pruni,the peak period were mainly distributed from 15:00 to 18:00,followed by 7:00 to 9:00;The average mating duration was 7.89±4.23 hours,varying from 1.80 hours to 19.67 hours.Through this study,it will helpful in understanding the biological characteristics of Illiberis pruni and guidance for prevention.
