| 摘 要： | 通过对梦尼夜蛾卵、幼虫、蛹的抽样,并利用聚集度指标法和频次分布法对其空间分布格局进行测定表明,梦尼夜蛾卵、幼虫、蛹均属聚集分布,其中卵、幼虫又同时符合负二项分布和奈曼分布,对形成此种分布的原因进行了分析。 |

| Abstract: | After sampling,aggregation index and frequency distribution methods are used to survey the spatial distribution pattern of eggs,larvae and pupae of Orthosia incerta Hufnagel.It reveals an aggregated distribution of the three stages of orthosia incerta hufnagel - eggs,larvae and pupae.Eggs and larvae also conform to negative binominal distribution and neyman distribution.This article analyzes the causes in forming the foregoing patterns. |
| Keywords: | orthosia incerta Hufnagel egg larva pupa spatial distribution pattern |
