摘要
根据福建省福州市日溪乡毛竹林内的系统调查资料 ,采用相关分析法和灰色关联度分析 ,探讨了刚竹毒蛾 Pantana phyllostachysae种群动态及与主要寄生性天敌寄生率相关性 .分析表明 ,刚竹毒蛾主要寄生性天敌卵期有黑卵蜂、平腹小蜂 ,幼虫期有绒茧蜂、脊茧蜂、黑点瘤姬蜂 ,天敌寄生量和林间虫口密度之间显著相关 ,天敌是造成种群消退的主要因子之一 。
Based on the field systematical investigation in Rixi,Fuzhou bamboo forest,the population dynamics of Pantana phyllostachysae and corelation between it and parasitism of main natural enemies were studied It was conclued that Telenomus sp and Anastatus sp were the main parasitic natural enemies in egg stage,and the Apenteles sp,Rogas sp,Xanthopimpla sp in larva stage The results of correlation analysis and gray sequence indicated the amount of parasite is obviously related to density of Pantana phyllostachysae,natural enemy is main factor of population decreasing,but not key factor
