摘要
丝带凤蝶Sericinus montelus是一种有开发价值的观赏昆虫,以蛹滞育越冬,成虫存在多型现象。本研究从体色、个体大小和蛹腹部刺突长度等方面比较了丝带凤蝶滞育与非滞育蛹及其成虫的形态差异。与非滞育蛹相比,滞育蛹体色较深,触角末端的淡黄色与体色差异明显,3日龄滞育蛹腹部第9节刺突长度是3日龄非滞育蛹的4倍左右,这些差异可以用于该虫蛹滞育早期判别。滞育蛹羽化成虫的翅展和尾突长度显著小于非滞育蛹羽化成虫,且腹部及翅面斑纹也存在明显的差异,这些差异与丝带凤蝶春型、夏型成虫的描述相一致,表明丝带凤蝶成虫季节多型是与滞育相关联的。
Sericinus montelus Gray is an ornamental insect with exploitability, which overwinters as diapause pupae, and adults have polymorphism. In this study, the morphology of diapause and non-diapause pupae and their adults were investigated in this butterfly in terms of color, body and wing size, and the length of spine on the 9th abdomen of pupae. Compared with non-diapause pupae, the color of diapuase pupae is darker. The faint yellow of antenna terminal is obviously different from the body color. The length of spine on the 9th abdomen of 3-day-old diapause pupae is about four times that of 3-day-old non-diapause pupae. Therefore, non-diapause and diapause pupae can be identified at this stage. The wingspan and tail length of adults from diapause pupae are significant smaller than those of adults from non-diapause pupae. There are also obvious differences in pattern of abdomen and wing. These differences are consistent with the descriptions of the spring form and summer form in this butterfly. The results suggest that the seasonal polymorphism of adult is related to diapause in S. montelus.
