摘要

对欧洲云杉树皮甲虫(ipstypgraphus, L.)的寄生蜂Rhopalicus tutela (Walker)的一些生物学特性在俄罗斯莫斯科地区的森林和实验室条件下进行了研究。雌蝶越冬后卵成熟，因此不需要额外的喂养来产卵。在8℃的实验室条件下，雄性的预期寿命为58±44天，雌性为36±45天。温度的升高缩短了黄毛鼠的发育周期，可以不滞育地进行发育。在22-24℃的实验室条件下，一个世代的持续时间为14-16天。在莫斯科地区的云杉林中，土特拉鼠每年繁殖两到三代。

Some biological traits of the parasitoid wasp Rhopalicus tutela (Hymenoptera: Pteromalidae) in spruce forests of Moscow Region, Russia

Some biological traits of Rhopalicus tutela (Walker), a parasitoid of the European spruce bark beetle Ips typographus (L.), were studied both in forests of Moscow Region, Russia, and under laboratory conditions. Females of R. tutela have mature eggs after overwintering and thus do not need additional feeding to lay eggs. Under laboratory conditions at 8 °C, the life expectancy of males is 58±44 days and that of females is 36±45 days. An increase of temperature shortens the developmental period of R. tutela, which can proceed without diapause. The duration of one generation in the laboratory at 22–24 °C is 14–16 days. In spruce forests of Moscow Region, R. tutela has two or three generations per year.
