Entomopathogenic fungi are a group of fungi that specifically target and infect insects as their host. These fungi have evolved a variety of mechanisms to penetrate insect cuticles, grow inside the insect body, and eventually kill the host. Some common examples of entomopathogenic fungi include Beauveria bassiana and Metarhizium anisopliae. Research in this area focuses on understanding the biology and ecology of entomopathogenic fungi, developing methods for mass production and application in pest control, and exploring their potential as sustainable alternatives to chemical pesticides. These fungi have shown promise in controlling a wide range of insect pests in agriculture, forestry, and public health, and their use is considered environmentally friendly and safe for non-target organisms.
