我们从1980—1983年对大袋蛾的繁殖习性进行了观察,现小结于下。 一、羽化: 1、雌、雄蛾的羽化呈现明显的不同步现象。雌蛾羽化期短而集中,雄蛾羽化期长而分散,但二者的盛期及峰期是重合的。据1980年调查,雄蛾羽化期为5月20日—6月30日,历时40天;盛期为5月28～6月19日,历时22天;峰期为6月10日前后。雌蛾羽化期为6月3日～6月17日,历时15天;盛期在6月5日～6月14日,历时10天,峰期 We observed from 1980 to 1983 the breeding habits of the giant moth, now summarized in the following. First, eclosion: 1, females, male moth feathers showed significant out-of-sync phenomenon. The female moths were short and concentrated, and the male moths had a long period of eclosion but dispersed. However, the peak and peak periods of the moths coincided. According to the survey in 1980, the male moth eclosion period was May 20 to June 30, which lasted 40 days; the peak period was May 28 to June 19, which lasted 22 days; the peak period was around June 10. The female moth eclosion period was from June 3 to June 17, which lasted 15 days; the peak ranged from June 5 to June 14, which lasted 10 days. The peak period
