Problems solved by technology

[0004] The inventor finds that the prevention and control of German cockroaches is still based on chemical control at present, but the use of a large amount of chemical insecticides not only has long-term damage to the ecological environment, but also makes German cockroaches produce a wide range of drug resistance. The biological control has the disadvantages of slow onset, long period, and short duration of control effect.

[0044] Metarhizium anisopliae spores and Serratia spp. were prepared into sterile aqueous suspensions and mixed uniformly to prepare the main agent (i.e. the insecticidal composition composed of Metarhizium anisopliae spores and Serratia spp.), wherein the Metarhizium anisopliae spores had no The spore concentration in the bacterial suspension and the concentration ratio of Serratia are shown in Table 1 respectively, and then the main agent is mixed into the ground adjuvant (oleic acid and brown sugar are mixed and ground in a mass ratio of 1:2.7) Auxiliary agent, oleic acid is heat-treated hot oleic acid, the oil temperature is 85 ℃) and pressed into powder preparation to obtain compound biopesticide, wherein, the content of main agent is 0.037-0.353wt%wt%, The content of the auxiliary agent is 99.647-99.963wt%.

Embodiment

[0049] Through a large number of indoor screening tests, the inventor found that the mixture of Metarhizium anisopliae and Serratia had a synergistic effect on Blattella germanica. In order to better understand the essence of the invention, the technical content of the present invention will be described in detail below in conjunction with examples, but the content of the present invention is not limited to this, and cannot therefore be interpreted as limiting the protection scope of the present invention.

Abstract

The invention provides a compound biological insecticide and a preparation method and an application thereof. The compound biological insecticide takes two microorganisms as active ingredients or an insecticidal composition compounded by the two microorganisms as a main agent. The two microorganisms are fungal spores and bacteria, wherein the fungal spores are green muscardine fungus pores and thebacteria are serratia marcescens. The synergic effect by compounding green muscardine fungus and serratia marcescens is obvious, the control effect is enhanced effectively, and defects that a singledose is slow in action, short in duration of effect and definite in insecticidal range are overcome.

Description

technical field [0001] The invention relates to the field of insect control, in particular to a compound biopesticide and its preparation method and application. Background technique [0002] Metarhizium anisopliae (Metarhizium anisopliae) belongs to the subphylum Metarhizium anisopliae, and is a broad-spectrum entomopathogenic fungus that can parasitize a variety of insects. It has the characteristics of wide distribution range, broad parasitic spectrum, etc., and is non-toxic to humans, livestock and crops. It is one of the most researched and used entomogenic fungi in the world. According to incomplete statistics, there are more than 200 kinds of insects in the world that can be infected and killed by this fungus. Metarhizium anisopliae has significant insecticidal effect, and has a new mechanism of action different from existing insecticides, mainly acting on the hemolymph immune system of insects, causing them to lose their immune defense functions. Metarhizium anisop...
