Ground dry dog or cat food encourages pupation.

地面干燥的狗或猫的食物，鼓励化蛹。

The pupation and eclosion were hindered by treatment of larvae.

处理的幼虫化蛹率，羽化而受阻。

The larvae had five instars, and exuviated at night, pupated at 5rd instar old larvae, pupation time need 2-4 days.

幼虫共有5龄，以夜晚蜕皮为主，5龄幼虫老熟后即觅地化蛹，化蛹持续时间2-4天。

The pupa starts a creamy white colour and changes slowly to brown during its pupation stage.

蛹开始奶油色和变化缓慢，布朗在其化蛹阶段。

The survival and pupation rates of the larvae increased with increase of larval weight because of water drinking.

幼虫的存活和化蛹率随幼虫饮水后体重的增加而增加。

After pupation, the CAT activity increased rapidly and reached the peak at the middle stage of pupae, then decreased rapidly until emergence.

化蛹后，CAT活性迅速升高，至蛹中期达峰值，随后下降直至羽化。

Genetic analysis on the inheritance of pupation rate and some traits of cocoon were adopted with diallel cross.

本试验采用完全双列杂交方法，对家蚕的生命力与茧质性状进行了遗传研究。
