Microspore strain and use thereof

Abstract

The invention provides a microspore strain extracted from paranosema locustae and an application thereof. The strain has quite strong specificity and has specific action of killing grassland locusts and farmland migratory locusts, and the killing effect is relatively good. The microspore strain extracted from the paranosema locustae of the invention can be used to control tens of locusts such as farmland migratory locusts, grassland locusts, paranosema locustae, bamboo locusts and rice locusts, etc.

Description

technical field The invention relates to the field of microspore products, in particular to a microspore isolated from the locust plant and its application. Background technique The locust plague is a worldwide natural disaster, which has had a great impact on agricultural production. Over the years, there have been frequent outbreaks of locust plagues in large areas, including farmland migratory locusts, grassland locusts, rice locusts, forestry cotton locusts, and bamboo locusts. Only farmland migratory locusts and grassland locusts occur 20 million mu and 60 million mu every year, seriously affecting agricultural and animal husbandry production. Since the 1980s in the United States, two-banded grasshoppers and black locusts were used as breeding hosts to cultivate No. locusts, and research on No. locusts has been carried out at home and abroad. However, the existing Microsporidium locusts are introduced from the United States, which are foreign species, and the ecologic...

AI Technical Summary

Problems solved by technology

However, the existing Microsporidium locusts are introduced from the United States, which are foreign species, and the ecological risk is relatively high after application; in addition, the existing Microsporidian locusts products have low specificity to locusts, and the control effect is unstable. Poor reversibility, weak resistance to high temperature and ultraviolet rays, and high production cost
