Inhibition of Dirofilaria immitis in gregarine-infected Aedes aegypti: preliminary observations.

Autor(es): Sneller V P

Resumo: This study examined some of the effects of Ascocystis culicis infections in Aedes aegypti mosquitoes and on the development of dog heartworm, Dirofilaria immitis, in A. culicis-infected A. aegypti. Infections of 100 or more gregarines had an adverse effect on mosquito larvae and the resulting pupae weighed 1 to 2 mg less than the gregarine-free stock mosquitoes. Intensity of gregarine-induced pathology of adult mosquitoes was best estimated by counting the cells of the Malpighian tubules. Larvae infected with approximately 100 gregarines per larva had at least half the number of cells in their tubules destroyed, and development of D. immitis was greatly reduced. Thus, gregarine infections may be useful in reducing populations of aedine mosquitoes and, in areas endemic for heartworm, may interrupt transmission of D. immitis
