摘要
二化螟主要以滞育高龄幼虫越冬,其越冬幼虫主要以水稻和茭白为寄主,其在寄主上的分布、年龄结构及冬后发育、越冬存活率等方面都具有一定规律。
Chilo suppressalis overwinter mainly rest on senior diapause larvae. Their overwintering larvae parasitize mainly on rice and water-oat. The certain laws of the parasite distribution on host, age structure, developmental capacities after the winter, and overwinter survival rates are reviewed in this paper.
