| 摘 要： | 通过2002年7～8月份的调查,得出桃潜叶蛾幼虫初期在桃树间和桃树内的空间分布型均属于普通的负二项分布。计算了桃潜叶蛾幼虫二阶抽样的理论抽样数,进行了桃潜叶蛾幼虫二阶抽样的序贯分析。

Study on Spatial Distribution Pattern of Larvae of Lyonetia clerkella and Its Two-stage Sampling Technique |
| |
| Abstract: | The investigation results showed that the spatial distribution pattern of the larvae of Lyonetia clerkella in peach garden and in peach tree all belonged to common negative binomial distribution. The theoretical two-stage sampling number for the larva of this insect pest was presented, and the two-stage sequence sampling technique was explored. |
