In pest management, what is the role of microorganisms?

Microorganisms play a significant role in pest management, particularly in the context of biological control. As biorationals, they are utilized to manage pest populations in a more environmentally friendly manner compared to traditional chemical pesticides. They can include beneficial bacteria, fungi, and protozoa that target specific pests, often with minimal impact on non-target organisms and the surrounding ecosystem. For instance, certain strains of bacteria can be pathogenic to specific insect pests, disrupting their life cycles without the harmful effects associated with synthetic chemicals.

Using microorganisms as biorationals aligns with integrated pest management strategies, which emphasize the use of a combination of biological, cultural, and chemical control methods. This approach helps in reducing reliance on synthetic pesticides, promoting sustainable agricultural practices, and improving overall ecological health.
