摘要
【目的】调查喀什地区杏园内食心虫的消长动态,为研究赤眼蜂防治的最佳时期提供理论依据。【方法】利用性诱剂诱捕探讨了杏园内主要食心虫的消长动态,通过悬挂蜂卡释放赤眼蜂,初步研究林间释放赤眼蜂防治食心虫效果。【结果】杏园内食心虫以苹果蠹蛾和梨小食心虫为主,经观测在喀什地区苹果蠹蛾1 a发生4代,梨小食心虫1 a发生5代,示范园内利用赤眼蜂防治统计蛀果减退率为45.63%。【结论】明确了防治的关键时期在越冬代及第1代幼虫期,应用赤眼蜂是防治食心虫的一种有效方法,为苹果蠹蛾和梨小食心虫的科学防治提供了理论依据。
【Objective】This article was carried out to investigate the growth and decline trends of two kinds of fruit-boring pests in Kashi to provide the theoretical basis for the control of Trichogramma.【Method】The method of sex attractant was used to discuss the population dynamics of these fruit-boring pests and hang Trichogramma egg cards.Controlling effect of Trichogramma fruit-boring pests were studied in Armeniaca vulgaris garden.【Result】The major populations of fruit-boring pests were Cydia pomonella L.and Grapholitha molesta Busck.Cydia pomonella L.has four generations in one year in the Kashi region,and Grapholitha molesta Busck has five generations in one year.In demonstration garden fruit-boring pests control statistics using Trichogramma was declined 45.63%.【Conclusion】It was clarified that the critical periods of protection are stage of winter larvae and first larvae.Using Trichogramma is an effective way to control fruit-boring pests.This research provided the theoretical basis for scientific control of Cydia pomonella L.and Grapholitha molesta Busck.
