摘要
采用系统取样和野外饲养的方法，测定出杨干透翅蛾幼虫有８个龄期；用零点标记法研究了幼虫的生长进度；同时通过野外取样调查。
The eight larval instars of Sesia siningensis (Hsu) were determined by systematic sampling and rearing in the field. The rate of growth of the larvae was studied by means of zero mark, and succession between groups of larvae of different years was observed by field sampling.
