绿盲蝽越冬卵在枣树上的空间分布型研究

Studies on the spacial distribution pattern of Lygus lucortum Mey er-Dur's over winter eggs in jujube trees

摘要: 利用6种空间分布型聚集度指标、Taylor幂法则及lwao回归法对绿盲蝽越冬卵的空间分布型进行测定结果表明，绿盲蝽越冬卵在枣树上呈聚集分布，且符合负二项分布，其聚集原因是由该虫习性与环境因素共同引起。并利用分布型参数确定了绿盲蝽越冬卵的理论抽样数。

Abstract: By using the index of 6 kinds of aggregation indices on spacial distribution pattern,Taylor's power principle,and Iwao's regression analysis method,the spacial distribution pattern of Lygus lucortumMeyer-Dur's over winter eggs was studied.The results show that these eggs are aggregation distribution on the jujube trees,which accords with minus binomial distribution.This distribution pattern results from the worm's habit and the cir cumstances.The theoretical sampling number of Lygus lucortumMeyer-Dur's over winter eggs is ascertained by the distribution indices.
