广腹螳平均卵块重和含卵量少于中华大刀螳 ,含卵量与卵块重呈正相关 ,平均孵化率分别是5 8 94%和 91 71 %。恒温条件下 ,广腹螳卵块平均孵化期分别为 5 6 2 2天 (2 0℃ ) ,3 0 71天 (2 5℃ )和 2 6 3 7天 (3 0℃ ) ,发育起始温度 1 2 65℃ ,有效积温 42 9 77日·度 ;中华大刀螳卵块平均孵化期分别为 5 0 9天(2 0℃ ) ,2 8 0 9天 (2 5℃ )和 2 1 77天 (3 0℃ ) ,发育起始温度 1 2 90℃ ,有效积温 3 62 42日·度 ;广腹螳卵块恒温孵化期短于相应变温组 ,中华大刀螳卵块恒温孵化期长于相应变温组。
The average weight of eggs and the number of ovoids in Guangzhan mantis were less than that in Chinese mantis mantis, and the number of ova was positively correlated with the weight of eggs. The average hatching rates were 58 94% and 91 71% respectively. Under the constant temperature conditions, the average hatching period of Guangzhu mantis was 562 days (20 ℃), 3101 days (25 ℃) and 263 days (30 ℃), and the developmental start temperature was 1 2 65 ℃, effective accumulated temperature 42 9 77 days · degrees. The average incubation period of Chinese knives mantissas was 59 days (20 ℃), 290 days (25 ℃) and 2175 days (30 days) ℃). The initial temperature of development was 1290 ℃ and the effective accumulated temperature was 3262.4 ℃. The incubation period was shorter than that of the corresponding temperature-changing group.
