Ultrastructural changes in the muscles, midgut, hemopoietic organ, imaginal discs and Malpighian tubules of the mosquito Aedes aegypti larvae infected by the fungus Coelomomyces stegomyiae

Fungi belonging to the genus Coelomomyces can infect mosquito larvae and de velop within the larval hemocoel. To examine fungal development, Aedes aegy pti larvae infected with Coelomomyces stegomyiae Keilin were fixed, embedde d and sectioned for both light and electron microscopy. While fungal hyphae of C. stegomyiae did not invade cells other than the cuticular epithelial cells, they did penetrate a number of tissues including muscles, midgut, he mopoietic organ, imaginal discs, and Malpighian tubules.
