摘要
梨瘿华蛾是梨树上的一种重要蛀干害虫.室内观察发现,梨瘿华蛾成虫寿命为7~9 d,羽化后2 d内为梨瘿华蛾求偶、交配的主要时期,交配次日可产卵;梨瘿华蛾日活动峰期主要发生于19:00-22:00;日求偶行为主要发生于19:00-22:00,此外在凌晨3:00-6:00也有求偶行为,但数量极少;梨瘿华蛾的日交配行为有两个峰期,第一个峰期为17:00-23:00,是主要交配阶段,第二个小峰期为6:00-9:00;其平均交配时长为89 min,从30~180 min不等.通过本研究有助于了解梨瘿华蛾生物学特点,同时,为防治梨瘿华蛾提供一定的参考.
Sinitinea pyrigolla is one of the important xylophagous insect in pear tree. Laboratory studies found that the lifespan of adult Sinitinea pyrigolla were 7~9 days. The courtship and mating mainly occurred within 2 days after eclosion. Daily activity peak mainly occurred at 19:00-22:00. Daily courtship mainly occurred from 19:00 to 22:00, except this period time, courtship also occurred in the morning from 3:00-6:00. There were two peaks of daily mating. The first peak appeared at 17:00-23:00 as the main mating phase. The second peak was small, appeared at 6:00-9:00. The average mating duration was 89 min, which varied from 30 min to 180 min. This study is helpful in understanding the biological characteristics of Sinitinea pyrigolla and provides guidance for the control and prevention.
