Penn State entomologists seek fungus to blunt mosquitoes' sense of smell

Sick people often lose their sense of smell and their appetite. If this happened to mosquitoes, they would not be able to feed on humans and spread malaria. A team of Penn State entomologists is looking for an insect disease that will infect mosquitoes and impair their sense of smell. Supported ...

Food security for leaf-cutting ants: Workers and their fungus garden reject endophyte invaders
