What are beneficial insects and how are they used in greenhouses?

Beneficial insects play a critical role in greenhouse management, primarily through their ability to control pest populations biologically. These insects are natural predators or parasitoids that attack harmful insects, like aphids, spider mites, or whiteflies, thus reducing the need for chemical pesticides.

By introducing beneficial insects such as ladybugs, lacewings, or parasitic wasps into the greenhouse environment, growers can create a more balanced ecosystem that promotes plant health. This method of pest control is integral to integrated pest management (IPM) strategies, which aim to minimize pest damage while maintaining ecological balance.

Using beneficial insects not only helps in managing pest populations effectively but also reduces the potential for pesticide resistance and minimizes the impact on beneficial organisms. This environmentally friendly approach enhances plant growth and health, fostering a robust production system that benefits from natural biological interactions.
