应用多元分析方法对烟台市牟平区红富士苹果园害虫与天敌群落进行了定量分析,采用最优分割法将苹果害虫与天敌群落的时序结构分为5个阶段,并分析了各个时序段害虫及天敌的发生特点.对害虫亚群落、捕食性天敌亚群落和寄生性天敌亚群落进行了主成分和因子分析,明确了不同时期起主要作用的害虫及其天敌种类.典型相关分析表明,主要害虫及其天敌类群之间存在显著相关性,其中金纹细蛾与其寄生蜂、绣线菊蚜与其寄生蜂、山楂叶螨与其专一性捕食性天敌深点颏瓢虫和东方钝绥螨之间的相关性高.
Multivariate analysis was used to quantitatively analyze the pest and natural enemy communities in Hongfuji apple orchard of Muping District in Yantai. The optimal segmentation method was used to divide the temporal structure of apple pests and natural enemy communities into five stages. The main pests and their natural enemies of pest sub-communities, predatory natural enemies sub-communities and parasitic natural enemy sub-communities were analyzed, and the main types of pests and their natural enemies were identified.The canonical correlation analysis showed that the main pests And their natural enemies. There was a significant correlation between their populations and their parasitic wasps, Spiraea intermedia, parasitic wasps, hawthorn spider mites and their specific predatory natural enemies, Chimonobambusa and Amblyseius orientalis High relevance.
