Scientists have created a comprehensive online database called EntomoFun 1.0 that catalogs nearly 1,800 documented cases of fungi that infect insects worldwide. This database brings together information scattered across hundreds of scientific papers and museum collections, showing which fungal species infect which insects and where these interactions occur geographically. This tool will help researchers understand how these fungal pathogens affect insect populations and ecosystems, and may eventually lead to better pest management strategies.
