This research discovered three new species of fungi in China that naturally infect and kill pest insects like whiteflies and scale insects. These findings are significant because: Bullet points of everyday impact: – These fungi could be developed into natural pesticides that are safer for the environment than chemical pesticides – The fungi may produce compounds useful for developing new medicines or other beneficial products – Understanding fungal biodiversity helps protect natural ecosystems and agricultural systems – This research advances our ability to control agricultural pests without harmful chemicals
