An Entomopathogenic Fungus for Control of Adult African Malaria Mosquitoes

Biological control of malaria mosquitoes in Africa has rarelybeen used in vector control programs. Recent developments inthis field show that certain fungi are virulent to adult Anophelesmosquitoes. Practical delivery of an entomopathogenic fungusthat infected and killed adult Anopheles gambiae, Africa's mainmalaria vector, was achieved in rural African village houses.An entomological inoculation rate model suggests that implementationof this vector control method, even at the observed moderatecoverage during a field study in Tanzania, would significantlyreduce malaria transmission intensity.
