Abstract
Antigonadotropins or hormones that inhibit egg development (oostatic hormones) have been found in the cockroach, eye gnat, crustaceans, house fly, and mosquitoes (Iwanov and Mescherskaya, 1935; Carlisle and Knowles, 1959; Adams et al., 1968; Meola and Lea, 1972; Else and Judson, 1972; Kelly et al., 1984; Borovsky, 1985; Kelly et al. 1986). Kelly et al. (1984, 1986) reported that crude extract of oostatic hormone from Musca domestica inhibited both egg development and the biosynthesis of ecdysteroids in the autogenous mosquito Aedes atropalpus which led them to believe that the role of oostatic hormone is to inhibit ecdysteroid biosynthesis in the ovary. On the other hand, Davey (1978) and Davey and Kunster (1981) suggested that in Rhodnius prolixus oostatic hormone inhibits JH stimulation of the ovary, thus blocking the transport of vitellogenin from the hemolymph into the ovary. Borovsky (1985) reported that a 7,000-fold purified mosquito oostatic hormone that was injected into female Aedes aegypti inhibited egg development and the biosynthesis of vitellogenin.
