Problems solved by technology

However, there are large differences in the toxicity of Beauveria bassiana of different geographical populations or different strains to pests. In biological control, it is often necessary to screen highly virulent strains for different types of pests; in addition, the control effect of Beauveria bassiana is affected by the high ambient humidity. When the relative humidity is low, the control effect is not ideal, and the insecticidal speed is relatively slow. Affected its enthusiasm in the control of agricultural and forestry pests
[0006] At present, there is a lack of a safe and nontoxic pine caterpillar polyhedrosis virus and beauveria bassiana insecticidal suspension and its preparation method and application

Description

technical field [0001] The invention relates to the technical field of biopesticide processing, in particular to a pine caterpillar polyhedrosis virus and beauveria bassiana insecticidal suspension and its preparation method and application. Background technique [0002] Masson pine caterpillar (Dendrolimus punctatus Walker), Lepidoptera (Lepidoptera), Lasiocampidae (Lasiocampidae), pine caterpillar (Tolype) insects, is the main pest of masson pine, frequent occurrence, serious damage, often rampant disaster, Seriously restrict the growth of masson pine. The inherent concept formed in some places for a long time regards the prevention and control of masson pine caterpillar only as a "disaster relief" work, and only pays attention to treating the symptoms and ignoring the root cause. Palliative treatment is also the pursuit of quick results, regardless of the severity of the infestation and the severity of the damage, regardless of the cost of control, blindly using a large ...
