Botrytis Cinerea Carried by Adult Fungus Gnats (Diptera: Sciaridae) in Container Nurseries

Gray mold (Botrytis cinerea Pers. ex Nocca. & Balb.) was the most frequently isolated pathogen cultured from external portions of adult fungus gnats— Bradysia spp. (Diptera: Sciaridae)— within greenhouses used to grow conifer seedlings in Idaho. Gnats were either collected from open water containers or standard yellow sticky traps. Characteristics and impact of fungus gnat infestations in greenhouses and control procedures for fungus gnats and B. cinerea are discussed. Tree Planters' Notes 46(2):48-53; 1995.
