绿盲蝽越冬卵在鲁北地区冬枣树上空间分布型及抽样技术研究
Studies on Spatial Distribution Pattern and Sampling Technique of Overwintering Eggs of Lygus lucortum on ‘Dongzao’Jujube Trees in Northern Shandong Province
摘要
Abstract
In the north of Shandong Province,with the popularizing of Bt cotton and the interplanting pattern of jujube with cotton in recent years,the Lygus lucortum occurred more rampantly and became the ma-jor pest.In order to make clear the spatial distribution of overwintering eggs of Lygus lucortum on ‘Dongzao’ jujube trees in the north of Shandong Province and carry out control measures effectively and timely,on the basis of forest survey,the spatial distribution pattern and sampling technique of overwintering eggs of Lygus lu-cortum were studied using random sampling and Iwao regression analysis.The results showed that the overwin-tering eggs of Lygus lucortum showed aggregation distribution on ‘Dongzao’jujube trees,which met the nega-tive binomial distribution.This distribution pattern resulted from the insect habits and the circumstances.As the same time,the optimal theoretical sampling number and sequential sampling model were determined with Iwao regression analysis.关键词
