Mosquitoes: female monogamy induced by male accessory gland substance.
Male accessory glands were implanted in virgin females of Aedes aegypti. When exposed to males, females copulated readily but were not inseminated; they remained sterile for life. Extract from one male could sterilize more than 64 females. The active principle may be a protein or peptide. Intraspecific transplant prevented insemination in 12 species, including Aedes, Anopheles, and Culex; interspecific transplant gave partial protection.
