控制实验与植物化学分析结果表明水稻挥发性物质和其它一些次生代谢物影响稻飞虱的寄主选择。水稻营养物质有类似作用,但它们的作用机理不同。天敌搜寻食物的行为依赖于来自不同营养阶层上的信息,化学信息起重要作用。在天敌选择寄主的过程中起作用的化学信息来自于寄主昆虫、食料植物或两者的相互作用,以及与寄主昆虫有联系的其它生物。其中来自寄主植物的化学信息非常重要.褐飞虱诱导的水稻挥发物对稻虱缨小蜂具有明显的引诱作用.稻虱缨小蜂同样依赖于稻飞虱的化学信息素来寻找寄主。
Controlled experiments and phytochemical analysis showed that rice volatiles and other secondary metabolites affected host planthopper selection. Rice nutrients have similar effects, but their mechanism of action is different. The behavior of predators searching for food depends on the information and chemical information from different trophic levels playing an important role. The chemical information that plays a role in the host’s selection of a predator comes from the interaction of host insects, food-bearing plants, or both, as well as other organisms associated with host insects. Among them, the chemical information from host plants is very important, and the rice volatiles induced by the brown planthopper (BPH) are obviously attractive to the small louse.Based on the chemical pheromone of rice planthoppers, the small louse also looks for the host.
