摘要: 为明确捕食螨对烟草蓟马的防治效果,本文调查了云南泸西中枢育苗期蓟马发生情况及种类,并对比研究了不同捕食螨释放数量、释放方式及携带微生物菌剂的防治差异。结果表明:蓟马种类主要为西花蓟马,其次为八节黄蓟马,发生高峰期在4月中旬左右;捕食螨投放100头/盘防治效果最好;均匀撒施捕食螨对蓟马防治效果显著优于开袋放置及空白对照(P<0.05);捕食螨搭载球孢白僵菌对蓟马控制效果最好,搭载金龟子绿僵菌与不带菌相差不大,但均显著高于空白对照(P<0.05)。

Abstract: The paper aims to verify the control efficacy of predatory mites against thrips at tobacco seedlingstage. The authors investigated the occurrence and species of thrips and comparatively studied the control efficacy of release quantities, methods and carried microbial agents of different predatory mites in Zhongshu, Luxi, Yunnan. The results showed that: the main species of thrips was Frankliniella occidentalis (Pergande), followed by Thrips flavidulus (Bagnall), the thrips reached the highest peak in mid-April; the release of 100 mites Amblyseius cucumeris (Oudemans) per tray provided the best control efficacy among different release quantities, and the uniform broadcast method was significantly (P<0.05) more effective than placed with an open bag and CK; the control efficacy of predatory mites carried with Beauveria bassiana Vuillemin was the best, and the control efficacy of predatory mites carried with Metarhizium anisopliae Sorokin were parallel to that without microbial agent, whereas both were significantly more effective than CK (P<0.05).
