The invention discloses a plant-source attractant of the aphid wasp and its application. Its characteristics are that the active ingredient of the plant-source attractant of the aphid wasp is composed of (E) beta basilene, beta laurene, methyl salicylate and beta caryophyllene. The invention also discloses the application of plant-derived attractants of the aphid wasp in the field of pest control. The plant-derived attractants of the aphid wasp of the invention can be added to the core of the attractant with slow-release effect to make a releaser for slow-release of the attractant. The attractant releaser can be evenly dispersed in the field and effectively improve the aphid wasp. The field dispersal ability increased the parasitism rate of Bemisia tabaci nymphs. The preparation method of the attractant is simple, which reduces the occupation of cultivated land and the complexity of agricultural operation compared with the planting plant attractant belt, and is suitable for large-scale application; the attractant can reduce the dosage of medicine, effectively reduce the pollution of ecological environment and pesticide residues in crops, and has remarkable ecological and social benefits.

一种丽蚜小蜂的植物源引诱剂及其应用
本专利技术涉及植物保护领域,尤其涉及一种丽蚜小蜂的植物源引诱剂及其应用。
技术介绍
丽蚜小蜂EncarsiaformosaGahan属膜翅目蚜小蜂科恩蚜小蜂属,是重要农业害虫烟粉虱Bemisiatabaci(Gennadius)和温室白粉虱Trialeurodesvaporariorum(Westwood)的寄生性天敌,能够有效控制其危害。由于烟粉虱和温室白粉虱寄主植物广泛,危害严重,抗药性产生迅速,因此采用生物防治技术就成为世界各国研究的热点。已有的研究表明丽蚜小蜂能够成功控制温室白粉虱的为害,而近年来,随着B型烟粉虱的入侵暴发,利用丽蚜小蜂等寄生性天敌控制B型烟粉虱的研究亦成为新的热点。植物挥发物在寄生蜂的寄主定位及选择过程中发挥着重要的作用。植食性昆虫可以利用寄主植物所释放的挥发物来指导其寄主定位行为,从而准确地找到其寄主植物。如蚜茧蜂Aphidiuservi能够利用蚕豆中的挥发物组分6-methyl-5-hepten-2-one进行寄主蚜虫的定位(Duetal.,1998);索诺弯边姬蜂Campoletissonorensis对棉花叶气味有定向反应,是通过对棉花气味的反应而找到寄主的(Elzenetal.,1984);寄生蜂Cotesiamarginiventris依靠虫害诱导的植物挥发物中的萜类物质(E-β-farnesene,E-ɑ-bergamotene)寻找为害的玉米植株(Schneeetal.,2006)。虫害诱导植物产生的挥发性次生物质(herbivore-inducedplantvolatiles, ...
