摘　　要：【目的】探索诱杀蚂蚁防治菠萝洁粉蚧的可行性,为菠萝洁粉蚧和菠萝凋萎病的防治提供新途径。【方法】对菠萝洁粉蚧共栖蚂蚁的种类进行调查,并采用田间小区试验法分别对施用蚂蚁毒饵及对照果园菠萝洁粉蚧种群消长动态和菠萝凋萎病发生情况进行调查。【结果】毒饵诱杀蚂蚁可以明显降低菠萝园菠萝洁粉蚧的种群数量,试验区菠萝凋萎病发病较轻,菠萝枯萎率为2.38%,而对照区菠萝凋萎病发病较重,菠萝枯萎率为15.73%。【结论】通过诱杀蚂蚁控制菠萝洁粉蚧种群数量,是防治菠萝凋萎病行之有效的新方法。[Objective]The purpose of the present study was to determine the feasibility of controlling pink pineapple mealybug by ant trapping in order to provide scientific references for controlling Dysmicoccus brevipes and mealybug wilt of pineapple.[Method]Ant species on pineapple were collected and identified.The natural population of pink pineapple mealybug and the incidence of mealybug wilt of pineapple in both control and treatment were investigated using field plot experiment method.[Result]The result indicated that ant trapping significantly reduced the population of D.brevipes,and the incidence of mealybug wilt of pineapple in treated fields （2.38％） was obviously slighter than that of controlled pineapple plant （15.73％）.[Conclusion]Ant trapping is a practicable measure of controlling pink pineapple mealybug wilt by controlling D.brevipes population.
