喷施非嗜食植物汁液对温室白粉虱的影响

温室白粉虱取食广泛,寄主繁多,但它也有非嗜食植物。非嗜食植物对温室白粉虱可能有很好的控制作用。研究了4种植物的汁液对温室白粉虱的影响,结果表明,供试植物的汁液对温室白粉虱都有很好的控制作用,使温室白粉虱落卵量减少65%以上。非嗜食植物次生物质在温室白粉虱的控制中会有良好的前景。

Effects of Spraying the Juice of Four Plants on Trialeurodes vaporariorum (Homoptera: Aleyrodidae)

Although the Greenhouse Whitefly (GWF), Trialeurodes vaporariorum has a lot of host plants, it still dislike having some plants. Those plants, which T. vaporariorum hates eating may control T. vaporariorum populations dramatically. This paper describes a laboratory study aimed at assessing the potential of plant juice for use as commercial insecticides. Insecticidal activity of 4 plant juices was assessed against each developmental stage (eggs and larva) of T. vaporariorum. Spraying plant juices reduced eggs more than 65%, so T. vaporariorum will be controlled significantly by various concentrations of plant juice. It will be a promising future to use secondary plant metabolites to control T. vaporariorum.
