天牛化学通讯及其在害虫综合治理中的应用

The Chemical Communication and Their Application in Integrated Pest Management in the Cerambycidae (Coleoptera)

天牛化学通讯机制的研究包括信息化学物质的鉴定及其在害虫综合治理中的应用,以及与信息化学物质紧密相关的天牛生殖行为特征。天牛的鞘翅、胸部和体表是产生信息素的主要部位,其短距离性信息素的碳链一般大于20个碳,长距离性信息素的碳链小于或等于10个碳,这一规律可为信息素的鉴定提供参考。应用植物源挥发物可作为引诱剂、驱避剂、拒食剂和产卵抑制剂调控天牛行为的特性来防治害虫。天牛的交配行为多数由短距离或接触性信息素启动,具有一定的生理节律和保护配偶现象,同时视觉、虫体颜色、形状、大小以及虫体体表化合物均可影响其交配行为。清楚了解天牛信息化学物质的特性及其生殖生物学,可充分发挥它们在害虫综合治理中的作用。

The research for chemical communication mechanism in Cerambycidae involved in identification of semiochemicals and application of them in the integrated pest management （ IPM）, reproductive behaviour characters relative to semiochemicals. The elytra, thorax and cuticle are main position released pheromone. The carbon chain of short-range pheromones is generally more than 20 carbons and about 10 carbons or less than it in the long-range pheromones. These rules may provide information for the identification of pheromones later. Plant volatiles are applied to control beetles in the chemical communication by characteristics of function as attractant, repellent, antifeedant and ovipositional deterrent to regulate insect behavior. Short range pheromones or contact pheromones are more used to motivate mating behavior which showed physiological rhythm and phenomenon of mate protection, vision, colour, shape and size of body and cuticular chemicals are effect factors in the mating behavior. The clear understand of characteristics of semiochemicals and reproductive biology will benefit their effective application in IPM.
