Abstract
Females from the same batch of Anopheles quadrimaculatus were fed upon 1 dog showing from 16,000 to 18,000 microfilariae of Dirofilaria immitis per cm.3 of blood, and upon another dog showing 30,000 to 34,000 parasites per cm. The mosquitoes were dissected 15 days after their infective meal. The 40 females fed upon the 1st dog had an avg. of 17.3 parasites each, whereas those fed upon the 2d dog averaged 99.3 filarial larvae. The majority of parasites in mosquitoes fed on the 1st dog were 3d stage larvae, whereas the filariae in mosquitoes fed upon the 2d dog were predominantly 2d stage larvae. Furthermore, of a total of 105 mosquitoes originally fed on the 1st dog, 50 survived for 15 days, whereas only 5% (45) of 900 mosquitoes fed on the 2d dog survived during the same period.
