Natural enemy insects have recently been used as a substitute for pesticides, which have been known to cause great damage to the ecosystem and soil.
The most well-known example is pest control by natural enemy.
This method studies which pest insects have a harmful effect on crops and forests and eliminates them by adding artificially raised natural enemies, or creating an environment favorable for natural enemies to grow.
This method shows slow effects but has a low impact on the environment, and crops can be produced safely without using pesticides.
Developed countries have begun active research and are developing and exporting various natural enemies.
The major means are artificial dissemination of natural enemies and luring natural enemies by raising plants that the predator prefers.
Pesticides that are ineffective on natural enemy insects are also used for maximum effect.
In Korea, the Rural Development Administration is researching application methods for natural enemy insects and currently applying the methods to strawberry, pepper, tomato, cucumber and watermelon cultivation. The major strawberry pest, Tetranychus urticae, can be prevented by deploying Phytoseiulus persimilis and the aphid can be reduced with ladybugs.
