摘要
新型生物防治方法逐渐替代了预防性差、持效性短的传统生物防治,它包括以延长天敌寿命、延长控害时间为目的的天敌植物支持系统、利用信息化合物调控害虫、天敌的行为与传统生物防治相结合的防治方法等。笔者从植物支持系统和化学生态调控粉虱、天敌两个方面综述了粉虱的生物防治研究现状。在农业生态环境中,植食性昆虫和天敌均会遇到多种气味物质,这些也是粉虱和天敌进行食物定位、寄主或猎物定位所依赖的主要通讯工具。通过查阅近20年来粉虱及其天敌的化学生态学相关研究,整理对粉虱在寄主植物定位、天敌定位粉虱过程中具有调节作用的植物挥发性物质及利它素。期望能在农业生产上将化学信息物质与植物支持系统联合使用,调控粉虱和天敌的行为,减少害虫对作物的危害,延长天敌寿命,增强生物防治效果。
Because of the less preventive and shorter control period,the traditional biological control is gradually replaced by new biological control methods.The new methodof plant-mediated support system can extend the natural enemies’life span and efficacy,and the other new methods can regulat the insects’behavior by semiochemicals on the base of traditional biological control.We reviewed the curreent situation of whiteflies’bio-control from the plant-mediated support systems and the behavior regulation of insect by using chemicals.Whitefly or natural enemies located their host plant or host/prey in agro-ecosystems,which mainly depend on the semiochemicals.Here we collected the chemical ecology references in the last two decades,and sorted out the plant volatiles and kairomone for manipulating the behavior of whitefly and natural enemies.Combined use of the synthesized semiochemicals and plant systems will regulate whiteflies’behavior to minimize the damage,or regulate enemies’behavior to expand its life span and fecundity,finally,the long-term sustainable control of whitefly will be achieved.
