棉钤虫某些生物学特性与滞育诱导关系的研究

利用人工诱那导滞育的方法，研究了棉铃虫幼虫历期及性别与蛹滞育率的关系。结果表明，棉铃虫三龄后幼虫历期越长蛹滞育率越高，而雌、雄蛹间滞育率无显著差异。

Study on the Relationship between Some Biological Properties and the Rate of Diapause Pupa of Cotton Boll Worm

The relationships between the growth stage of larva and the rate of diapause pupa,and between the sex and the rate of diapause pupa of Cotton Boll worm were studied with the methods of artificially induced diapause.Te results indicated that the longer the larval stage of Heliothis armigera after 3 age was,the higher the rate of diapause pupa was and that the relationship between the sex and the rate of diapause puap was not significant.
