摘　　要：西花蓟马在烟草上发生较常见,可对烟叶产量和质量造成严重影响,在云南烟区的传毒为害呈逐年加重趋势,因此,蓟马的生物防治研究成为产业需要。本文在昆明开展了巴氏新小绥螨和剑毛帕厉螨与球孢白僵菌联合应用防治烟草西花蓟马的田间研究,试验结果表明:释放巴氏新小绥螨和剑毛帕厉螨并与球孢白僵菌联合应用对西花蓟马都有一定控制作用,7 d后防治效果可达100%;尤其是剑毛帕厉螨对西花蓟马蛹具有持续稳定的防治效果,与球孢白僵菌配合,处理3 d后防效即可达到50%,第5 d达到100%;各处理到15 d以后,烟田中已监测不到西花蓟马活体。因此本研究以期为烟草西花蓟马的绿色可持续防治提供参考。Western flower thrips Frankliniella occidentalis Pergande occurring more commonly in tobacco can cause serious damages on yield and quality,in particular in recent Yunnan tobacco area.Thus,there’s an urgent need for biological control of F.occidentalis in tobacco industry.In this paper,we conducted the field research to investigate the biocontrol potentials of thrips by combined applications of predatory mites Neoseiulus barkeri and Stratiolaelaps scimitus as well as entomogenous fungus Beauveria bassiana in Kuanzhuang county of Kunming City in Yunnan Province.The results showed that the application of three biocontrol agents had positive effect on thrips control,as the control effect was up to 100%in 7 days.Predatory mites have a stable and sustained control effect on the thrips nymphs,when the control effect reached to 50%in 3 days and 100%in 5 days in combination with B.bassiana.The living thrips could not be detected in the tobacco field after 15 days of the treatments.Therefore,our study has provided a reference for the sound and sustainable control of thrips in tobacco.
