Beauveria is a genus of fungi known for its ability to infect and kill insects. These fungi are often used in biological pest control, as they can help manage pest populations without the need for chemical pesticides. The spores of Beauveria attach to the exoskeleton of insects, germinate, and penetrate their bodies, ultimately leading to the insect's death. The most well-known species within this genus is Beauveria bassiana, which is effective against a variety of agricultural pests. This natural method of pest control is gaining popularity due to its environmental benefits and reduced impact on non-target organisms, making it a sustainable alternative in agriculture.
