摘要
为有效防治烟田西花蓟马和烟草番茄斑萎病,分别在烟草移栽期和团棵期研究释放捕食螨种类、密度及捕食螨带白僵菌对烟田西花蓟马引起烟草番茄斑萎病的控制效果。结果表明:释放斯氏钝绥螨对烟草番茄斑萎病的控制效果略好于胡瓜钝绥螨;结合成本和防效考虑,移栽期和团棵期胡氏钝绥螨较适宜的释放密度分别为2.25×10~6头/hm^2和3.75×10~6头/hm^2;释放带球孢白僵菌的捕食螨防效低于不带球孢白僵菌的捕食螨。
In order to effectively control thrips and tobacco tomato spotted wilt disease,the control efficacy of tobacco tomato spotted wilt disease infected by thrips was studied in transplanting stage and rosette stage by releasing different predatory mite species with different density and Beauveria bassiana.Results：Releasing A.swirskii is better than A.cucumeris,considering the cost and control efficiency,better control efficiency could be achieved by releasing 2.25 ×10~6/hm^2 at transplanting stage and3.75 ×10~6/hm^2 at rosette stage.The control efficacy of predatory mites with B.bassiana was lower than that without B.bassiana.
