| 摘 要： | 茉莉酸甲酯、水杨酸甲酯和芳樟醇是水稻受虫害诱导后产生的重要挥发物性物质。它们通过直接或间接的途径,参与植物抵抗病虫害的过程中。通过田间调查和昆虫触角电生理分析,对这3种挥发物在稻田节肢动物群落和嗅觉行为水平上的作用进行了研究。结果发现水杨酸甲酯对害虫的虫口密度影响较明显,晚稻田中,水杨酸甲酯组的害虫数量(14.42头/板)显著高于其余各处理组。赤眼蜂的嗅觉电位随芳樟醇和茉莉酸甲酯浓度的升高而显著增大,浓度为1/50时赤眼蜂嗅觉电位的变化值显著高于浓度为1/5000时嗅觉电位变化值。

| Abstract: | Rice plants released complex volatiles that were considered as signal molecules respond to insects.Methyl jasmonate(Me-JA),Methyl salicylate(Me-SA) and Linalool(Lin) were three of the most important.They can induce chemical defenses of the plants directly or indirectly.In order to understand the effects of rice volatiles on the community structure and olfactory behavior of arthropods in the rice field,the effects of three volatiles on the arthropods population and community in the fields were studied in thi... |
