【目的】拒食剂是通过改变农作物对害虫的适口性来调控其取食行为的一大类化学物质。使用拒食剂对害虫取食行为进行生态调控,可有效地克服化学防治带来的负面影响。但害虫随着取食经历会对拒食剂表现出很强的味觉适应能力,尤其是味觉习惯化限制了这类物质的大田应用。论文旨在明确两种酰胺类拒食剂胡椒碱和山椒醇作用于多食性棉铃虫(Helicoverpa armigera)幼虫的感觉器官类型,以及两种拒食剂取食经历对棉铃虫后期取食行为的影响,为此类拒食剂在农田大规模应用提供依据。【方法】首先在两项选择式条件下,测试棉铃虫幼虫对胡椒碱和山椒醇的嗅觉趋向性反应,并在非选择性条件下测定棉铃虫幼虫在首次...

[Objective]Feeding deterrents or anti-feedants are a broad range of chemicals regulating the feeding behaviour via altering the palatability of crops to herbivores. The idea of pest ecological control using feeding deterrents is an alternative strategy to overcome the negative effect of chemical control. However, almost all insect pests can develop experience-dependent adaptivity to various feeding deterrents, especially gustatory habituation, which limited the practical use of these substances. The objective of this study is to elucidate the s...
