PBS与小球孢白僵菌复配对温室小菜蛾幼虫的防治效果
Control Effect of PBS Combined With Beauveria bassianaon Plutella xylostellain Greenhouse
摘要
Abstract
Control effects of Beauveria bassiana on Plutella xylostella in frigid regions were studied.The content of Beauveria bassiana was measured by plate counting method.Beauveria bassiana was prepared into 5 concentrations of fungal suspension,named as G1 to G5;the control effect was taken as the experimental standard,to find out the optimal concentration ratio.The experimental data show that the culture of fungi with PBS can protect the activity and integrity of microorganisms more than distilled water at different concentrations.The lethal effect of the compound suspension on the greenhouse pests in the cold is more obvious.Moreover,the Plutella xylostella fatality rate of the mixture with different concentration was different,with concentrations between G1 and G5,could be formulated as biological pesticides for the control.However,in the process of pest control in greenhouse in cold region,the compound suspension of Beauveria bassiana with concentration of G1 had the highest control effect.On the whole,the uspension of Beauveria bassiana compound with concentration of 3×107 cfu/mL was superior to other compound components.关键词
