Experimental infections of , and were induced in males and females of a strain of originally selected for susceptibility to . Mosquitoes were inoculated intrathoracically with microfilariae from the skins of animals infected with the three parasites. Percentages of female harboring third-stage larvae 9 or more days after inoculation were 22.5% for , 11.1% for and 14.4% for . Infection rates among male mosquitoes were 39.5% for and 16.15% for . Although did develop to the third larval stage in males, high mosquito mortality prevented estimation of the rate of susceptibility. Infection rates among mosquitoes inoculated with cryopreserved microfilariae of were similar to those in mosquitoes inoculated with microfilariae from fresh skin snips. Of the three species of filariae studied, only had a pronounced pathological effect on the inoculated mosquitoes. While most larvae recovered from were normal, pathologies similar to those exhibited by other filariae developing in abnormal hosts were noted in some individuals.
