摘要: 在室内温度控制条件下,空心莲子草叶甲卵、幼虫、蛹的生长发育历期与温度呈函数关系,在22、25、28、30和32℃下,随着温度的提高,发育历期呈明显下降.幼虫有3龄,幼虫期8.8d.成虫寿命长短与温度和性别有关,雌虫寿命比雄虫长,成虫产卵前期1.5~5.0d之间,产卵期11.5~116.0d之间.卵、幼虫、蛹的起始温度分别是12.4、12℃,有效积温分别是69.192、125日度.

Abstract: Results from experiments under controlled temperature showed that there exists a functional relationship between the development durations of egg, larvae and pupae of Agasicles hgrophila and the temperature.From 22 to 32℃,the development durations are obviously shortened with increasing temperature.The larval period has three instats and endures 8.8 days.The life span of adult is related to temperature and sex,and the females live longer than the males.The period of pre oviposition varies from 1.5 to 5.0 days, and that of oviposition from 11.5 to 116.0 days.The initial temperature of egg,larvae and pupae development is 12.4 and 12℃, and the effective accumulative temperature of them is 69.192 and 125℃,respectively.
