摘要
二化螟绒茧蜂以低龄幼虫在滞育的二化螟幼虫体内越冬。实验条件下还可寄生芦苇螟和荻蛀茎夜蛾。该蜂行两性生殖和产雄孤雌生殖。雌蜂平均产卵119粒,在寄主体内的出蜂量与寄主龄期呈线性正相关,寄生在4龄寄主体内的发育速率最快,蜂体大小与寄主出蜂量呈线性负相关。
Apanteles chilonis overwintered in the early larval stage inside the diapaused larvae of Chilo suppressalis. Laboratory studies revealed that the parasite also parasitized Sesamia sp, and reed borer, Chilo sp. It performed sexual and thelyotokous reproduction. The average fecundity of the parasite was 119 eggs per female. Later instar host larvae produced more parasites, while the size of the parasite was negatively correlated with the number of parasites emerged from a host.
