【摘要】 通过野外设计混交林试验区,测定锈色粒肩天牛补充营养和产卵选择行为,结果表明:该虫在国槐和香花槐上取食量和产卵量最大,在黄山栾上有少量取食和产卵,在垂柳上不取食、不产卵。利用国槐枝叶的粗提液野外诱集该虫的试验表明:枝条40 min后的馏出液对该虫的诱集效果最佳,每个诱捕器每周平均诱集7.42头。该研究为明确锈色粒肩天牛的寄主范围和进一步研制植物源引诱剂提供了理论依据。更多还原

【Abstract】 The field stady of the feeding and oviposition preference of Apriona swainsoni in nubde showed that the feeding and oviposition amount on Sopora japonica and Robinia pseudoacacia,were the biggest while just a few emerged on Koelreuteria paniculata,but nothing on Salix babylonica.The result of trap test showed that using distillate of twigs and foliage of S.japonica can monitor A.swainsoni in a wide range,each trap could catch 7.42 heads of A.swainsoni weekly on the average.The research laid the foundation for clarification of host range of A.swainsoni and would provide scientific and theoretic basis for further research for plant attractants.更多还原
