Abstract

The use of conventional synthetic insecticides to manage mites population poses great difficulties owing to their cryptic nature and has, therefore led to growing interest in novel and effective alternatives like microbial bio-control agents. Successful usage of entomopathogenic fungi for pest control under field conditions includes delivery techniques, infectivity and persistence of their inoculum in the environment. Microplot experiment on chilli mite, Polyphagotarsonemus latus Banks revealed that the oil based formulation of B. bassiana (Bb 112) was significantly superior to all other treatments and recorded the highest cumulative mean population reduction of 39.80 percent. Two field experiments conducted against chilli mite, the cumulative mean percent reduction in the first field trial at Kumarapalayam and the second one at Ambilikkai showed that oil based formulation of B. bassiana, Bb 112 @ 108 spores mL-1 sprayed with CDA sprayer was significantly superior to other treatments with 39.27 and 45.86 per cent reduction respectively.

球孢白僵菌油基制剂的疗效研究VUILL。对辣椒螨，多食蛾蛾通过不同的输送设备输送

由于传统合成杀虫剂的隐蔽性，使用它们来管理螨虫种群带来了巨大的困难，因此人们对微生物生物控制剂等新型有效替代品越来越感兴趣。昆虫病原真菌在田间条件下成功用于害虫防治包括递送技术、感染性和接种物在环境中的持久性。对辣椒螨Polyphagotarsonemus latus Banks进行的微孔试验表明，球孢芽孢杆菌（Bb 112）的油基配方显著优于所有其他处理，并记录了最高的累积平均种群减少39.80%。Kumarapalayam和Ambilikkai的第一次田间试验和第二次田间试验对辣椒螨进行的两次田间试验的累积平均减少百分比表明，用CDA喷雾器喷雾的球孢B.B 112@108孢子mL-1油基制剂显著优于其他处理，分别减少39.27%和45.86%。
