摘 要: 西花蓟马(Frankliniella occidentalis)是重要的农业害虫,胡瓜钝绥螨(Amblyseius cucumeris)是西花蓟马的重要捕食性天敌,对西花蓟马有明显的控制作用。花粉对害虫西花蓟马的生长发育和繁殖有一定的促进作用,同时花粉是天敌胡瓜钝绥螨的替代饲料,能增加胡瓜钝绥螨种群数量。文中总结了花粉在胡瓜钝绥螨控制西花蓟马中的作用,为进一步加强花粉的增效作用和提高捕食性天敌的利用效率提供依据。 Western flower thrips, FranklinieUa occidentalis (Pergande) is one of the most serious pests. Predatory mite Amblyseius cucumeris is the most important biological agent, and demonstrates the active effect to control F. occidentalis. Although pollen has a positive effect on the development and fecundity of F. occ/denta//s, it is also an alternative food of A. cucumer/s, thereby showes the positive effect on predator population growth. The effect of pollen on both F. occiden- talis and A. cucumeris is summarized, which would provide the basis for the effective usage of pollen and enhance the ef- ficiency of A. cucumeris.
