| 摘 要： | 植物源挥发物和昆虫信息素是昆虫的重要信息物质，二者协同作用以调节昆虫的行为.通过增加触角电位、信息素接收神经元动作电位和脉冲频率，特异性植物源挥发物能显著增强昆虫性信息素和聚集信息素的引诱力.这种对昆虫信息素的增效作用受昆虫体内的章鱼胺及其受体介导.特异性植物源挥发物和章鱼胺受体结合，降低性信息素接收神经元对性信息素的反应阈值，增强性信息素接收神经元敏感性.这可能是植物源挥发物对昆虫信息素具有增效作用的主要机制.

| Abstract: | Host plant volatiles and insect pheromones are the most important semiochemicals for insects, and their synergism can modulate insect behaviors. The attraction to sex- and aggregation pheromones of insects can be greatly enhanced by specific plant volatiles through the increased electroantennogram, pheromone incepting neuron action potential, and pulse-frequency. When the specific plant volatiles are bound with octopamine receptors, the threshold of sex pheromone incepting neuron to sex pheromones is decreased, while the sensibility of sex pheromone incepting neuron is increased, which may be the main mechanism for the synergism of plant volatiles to insect pheromones. |
