Summary Studies were conducted via light and electron microscopy to determine, relative to the biology of Culicinomvces clavosporus, the following) (1) ultrastructure of the conidium; (2) infection of mosquito larvae (Aedes aegynti and A. taeniorhynchus); (3) host/parasite interactions at the cellular level; and (4) fungal conidiogenesis. Larvae become infected by submerged conidia through the cuticle of the foregut and hindgut and, when exposed to high concentrations of conidia (10⁴-10⁶ conidia/ml), through the epicuticle of the anal gills as well. As the fungus grows throughout the hemocoel, larval movements become increasingly sluggish. Hyphae grow to completely pack the anal gills about the time of larval death and subsequently nurture the thin epicuticle. Following this, the abdomen, thorax, and head become packed with hyphae. Hyphae then rupture the epicuticle in all regions but the head and siphon. Within 24 hours, conidia are formed on the emergent vegetative hyphae.
