The prevention and control of life in a broad sense is the use of bacteria, viruses, etc. in prokaryotes, flagellates, microsporidia, etc. in protozoa, insecticidal plants in plants, Beauveria bassiana, Metarhizium, etc. in animals The pests are natural enemy animals to antagonize the control of pests. Due to the traditional pesticide concept and the influence of application technology and the limitation of factory production, the current biological pesticides mainly refer to pesticides constructed by bacteria, actinomycetes, molds, viruses and their products in microorganisms. People usually refer to biological pesticides as microbial pesticides. .

In nature, there are nearly 3,000 microorganisms known to kill pests, which cause disease and death of pests by parasitizing inside and outside the body of the pest. Some also directly cause pests to die by their metabolites. The use of biological pesticides has the following advantages in controlling agricultural and forestry pests:
1. Pests are not susceptible to drug resistance;
Second, the selectivity is good;
Third, the pathogens are transmitted through epidemic, effective and effective afterwards;
Fourth, there are long-term economic benefits.

But everything has its two sides. The way bio-pesticides work is to infect insects through microbial proliferation, and there is a sick process in insects. Relatively to the effect of chemical pesticides, its action time is slower, but once the insects are infected, they usually lag behind or stop eating until they die.

In view of the good compatibility of biological pesticides with agricultural production, environmental protection and social development, the development of biological pesticides and the prevention and control of agricultural and forestry pests has become an important development direction at home and abroad and biological control.
