Antibacterial, anti-dry and anti-adhesion method of dead insects infected by entomopathogenetic nematodes

Abstract

The method performs surface treatment on dead insects resulted from infection of entomopathogenetic nematodes (entomopathogenetic nematodes and insect complexes) through a three-step method. Firstly, anti-dry and antibacterial treatment is performed on the insect complexes infected by the entomopathogenetic nematodes; the insect complexes infected by the entomopathogenetic nematodes are immersed in a mixed solution of kaolin, glycerin soil and water; then further surface treatment is carried out in mixed powder of kaolin starch and vermiculite; and finally, edible pigment is sprayed to make the surface treated dead insects infected by the entomopathogenetic nematodes red color. The surface treated dead insects infected by the entomopathogenetic nematodes can release the entomopathogenetic nematodes normally. Surface treated dead insect agents solve the problems of adhesion and decay during a transport process and guarantees release rate of the entomopathogenetic nematodes. The method is simple and practical, is helpful for large-scale application of the dead insects infected by the entomopathogenetic nematodes.

Description

Technical field [0001] The invention relates to an antibacterial, anti-drying and anti-adhesion treatment on insect corpses infected with insect pathogenic nematodes, which is beneficial to the development of insect pathogenic nematodes in insect bodies and the transportation and field application of insect corpses infected with insect pathogenic nematodes. Background technique [0002] Entomopathogenic nematodes, referred to as EPNs (Entomopathogenic Nematodes), have been a hot spot in the research of biological control of pests in recent years, mainly used to control underground pests to protect specific plants. It mainly includes Steinernema (Steinernema) and Heterorhabditis (Heterorhabditis). [0003] Entomopathogenic nematodes, as an ideal biological insecticide, have the following advantages: obligate parasitism, a wide range of hosts, and active search capabilities; they can start from the natural openings (such as mouthparts, airways and anus), wounds or knots of host insec...

AI Technical Summary

Problems solved by technology

However, insect corpses infected with entomopathogenic nematodes are easy to rot and stick to each other, making it difficult to store, transport and apply in the field, and stress factors such as drying seriously affect the development of entomopathogenic nematodes in insects

These factors greatly limit the popularization and application of insect carcasses infected with entomopathogenic nematodes in the control of harmful insects
