Embodiment Construction

[0028] The present invention will be described in detail below through specific embodiments.

[0029] 1. Paranosema locustae screening:

[0030] 1. Test strains

[0031] The spore isolation and inoculation method was used to isolate and purify the susceptible locusts collected in the field to obtain 10 microspore strains from different sources, and then inoculated them into different types of locusts, and the locusts were raised under suitable conditions.

[0032] 2. Insect source

[0033] The source of insects is mainly locust Locusta Migratoria and car locust Gastrimargusmarmoratus.

[0034] 3. Experimental population

[0035] 3.1 Laboratory population

[0036] Collected in the field, and raised in the laboratory to establish experimental populations. The feeding conditions are temperature 28-35° C., relative humidity 60-80%, and light 12:12. Feed fresh corn seedlings every day.

[0037] 3.2 Field population

[0038] A population that grows and develops naturally und...

Abstract

The invention provides a preparation containing 8-year-old microspores (P8) and 9-year-old microspores (P9) separated from Oedaleus asiaticus, and the preparation method thereof. The microspore preparation can be used for preventing and treating dozens of locusts such as farmland migratory locusts, grassland migratory locusts, Oedaleus asiaticus, bamboo locusts, rice locusts, etc, and can remarkably improve the locust control effect and ensure the stable prevention effect.

Description

technical field [0001] The invention relates to the field of microspore products, in particular to a preparation of microspores isolated from the locust plant and a production process thereof. Background technique [0002] 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 forestry 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 ...
