越冬代中华草蛉成虫,在越冬前取食一定的时间后,均能改变体色,开始越冬。越冬期间的死亡率与冬前取食时间的长短及取食量有密切的关系。冬前获得充足营养的成虫贮存在不生火的屋内,越冬期间死亡率很低,至8月20日成活率仍有80％;而没有充分取食的成虫则大量死亡。作者认为北京地区每年春季草蛉数量很少与越冬前田间成虫食料不足,因而越冬期间大量死亡有关。对保护草蛉越冬的途径提出了建议。 Overwintering generation of Chinese grass worm adults, eating before winter over a period of time, can change the color, began overwintering. The mortality rate during winter is closely related to the length of winter feeding and the amount of food consumed. Adults with adequate nutrition before winter were housed in unkempt houses with low mortality during winter and 80% surviving as of August 20, while adults who did not feed well died in large numbers. The authors believe that the annual spring seasons in northern China are scarcely related to the lack of foodstuffs in the field before harvest, resulting in a large number of deaths during the winter. Proposed ways to protect wintering wintering.
