研究了2年一代落叶松毛虫DendrolimusSuperans(Butler)的生物学特性。完成一个世代跨3个年度730d左右,下一世代约有10%进入1年一代虫,1年一代虫的下一世代均进入2年一代虫。2年一代虫在第2年的小暑及大暑期间进行越夏。大虫、小虫在奇数、偶数年间交替发生
The biological characteristics of 2-year-old DendrolimusSuperans (Butler) were studied. To complete a generation across three years 730d or so, about 10% of the next generation into a generation of worms, one generation of insects into the next generation have two generations of worms. 2-year-old insects in the first two years of summer and summer heat summer. Large insects, bugs in the odd, even in the years alternately
