知られている。2. Description of the Related Art Looking at the life cycle of many pests, eggs → larvae → pupae → adults are performed on the ground, but beetles,
It is known that some larvae such as the leaf fly and the fruit fly, and thrips such as the flower thrips and the flower thrips, spend the period of larvae and pupae in the soil.

いるのが現状である。On the other hand, as a technique for controlling these soil pests, soil disinfection with pesticides has been the mainstream for a long time, but these methods also exhaust beneficial insects and useful microorganisms to one net, which destroys the soil ecosystem and causes crop damage. It has a considerable negative effect on growth. For this reason, it has been attempted to control soil pests using natural enemy microorganisms such as insect sclerosis fungi to protect the ecosystem, but it is difficult to settle for a long period of time due to environmental factors in the soil, so it is limited in very limited places. It is currently being implemented.
