Embodiment Construction
[0018] The present invention will be described in detail below through specific embodiments.
[0019] 1. Microspore (Paranosema locustae) screening:
[0020] 1. Test strains
[0021] The spore isolation and inoculation method was used to isolate and purify the susceptible locusts collected in the field, and 10 microspore strains from different sources were obtained, and then inoculated into different types of locusts, and the locusts were raised under suitable conditions.
[0022] 2. Insect source
[0023] The source of insects is mainly locust Locusta Migratoria and car locust Gastrimargusmarmoratus.
[0024] 3. Experimental population
[0025] 3.1 Laboratory population
[0026] 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.
[0027] 3.2 Field population
[0028] A population that grows and devel...
