| 摘 要： | 在温度２５℃、空心莲子草叶甲卵、幼虫、蛹期最长分别为６．８．１１和１１．６ｄ，最短为２．８，６和７．６ｄ．３种虫态在５种温度下，随温度的提高，发育历期呈明显下降．成虫寿命比雄虫长．成虫产卵前期为１．５—５．０ｄ，产卵期１１．５－１１６．０ｄ．产卵量为２９－２６３６粒，平均为１２９５粒．相对湿度越大，卵的孵化率越高；在湿度２２－２８℃时，孵化率随温度的升高而增大，高于２８℃时，温度升高，孵化率减少；大于３２℃时卵不发育。关键词

| Abstract: | Under controlled conditions,the maximum period for egg,larvae and pupae were 6.8,11 and 11.6 days respectively and the minimum 2.8,6 and 7.6 days at25℃.Mean developemental times through thtee larval instars was 8.8 days.The duration of developement and pupae subjected to 5 different temperatures (22,25,28,30and 32℃)decreases in a fairly regular manner at temperature rise.Adult longevity was vafiable according to temperature and aex.Females lived longer than males.The pre-oviposition period varied from 1.5 to 5.0 days and the oviposition from 11.5 to 116 days.Number of eggs per female was from 29 to 2636.The average of fecundity was 1295.Hatching success of eggs increased significantly when the humidity rises between 70% to 90%.Survival rate of larvae peaked at 28℃. |
