Relative Efficiency of Six Species of Mosquitoes from Guam, M. I., as Developmental Hosts for Dirofilaria immitis

Abstract

Six spp. of mosquitoes[long dash]Aedes guamensis, A. pandani, Culex annulirostris, C. qutnquefasciatus, A. aegypti, and C. sitiens[long dash]were studied on Guam to determine their relative efficiency as developmental hosts for Dirofilaria immitis. The number of infective-stage larvae developing in from 25 to 120 specimens of these spp. of mosquitoes averaged 5.5, 2.3, 0.6, 0.4, 0.2, and 0.2, respectively. The respective percentages of the mosquitoes infected with infective-stage larvae were 68, 57, 27, 23, 2, and 15.
