粉蚧化学生态学研究进展

粉蚧是农林经济作物的一类重要害虫，由于体表覆盖一层蜡粉，化学防治常需要大剂量反复用药该虫才能得以控制，易造成环境污染及害虫再猖獗。本文从昆虫化学生态学的角度综述了粉蚧类害虫的寄主植物范围、天敌应用以及三重营养关系研究进展，归纳已鉴定粉蚧性信息素化学结构特点及其在综合防治中应用概况，探讨粉蚧类害虫化学生态学未来研究方向，为其绿色防控提供理论基础。

Research progress on the chemical ecology of mealybugs

Mealybugs are important pests in agriculture crops and forestry plants. Large amounts of chemical pesticides need to be applied to control mealybugs which are covered with a powdery wax. However, dependence on insecticides has ultimately resulted in environmental pollution and increased incidence of pest resurgence. From the perspective of insect chemical ecology, it was reviewed the progress on the host plant range, application of natural enemies and the triple nutrition relationship of mealybugs in this paper. Meanwhile, the chemical structure characteristics and application of identified sex pheromones in mealybugs were summarized, and the future research direction of chemical ecology in mealybugs was discussed, which would provide a theoretical basis for the green control of mealybugs.
