豆天蛾(Clanis bilineata Wolker)在大部分地区1年仅发生1代,周期较长,不利加速对该虫的防治和生物学研究。为研究观察豆天蛾成虫的行为,笔者对促使越冬豆天蛾幼虫室内化蛹方法进行了初步摸索。现将结果整理如下: Cladosporium bilineata (Clanis bilineata Wolker) occurred in most areas only 1 generation a year, longer cycle, adversely accelerate the prevention and treatment of the worm and biological studies. In order to study the behavior of the adult Beet armyworm, I conducted a preliminary exploration on the method of pupae indoors to promote larvae overwintering. The results are now organized as follows:
