Abstract

Summary

Comparative observations on the fate of ingested microfilariae of in 5 species (8 strains) of mosquitoes demonstrate that consistent failure of microfilariae to migrate in a species of mosquito to the thoracic muscles 1 hour or 1 day after being ingested indicates inefficient vector-ability. However, a high rate of migration of microfilariae does not necessarily indicate a high degree of vector efficiency, since this is not always correlated with successful later development of the filariae.

A high degree of successful migration occurred in (2 laboratory strains) and in (wild), while development to the infective larval stage occurred in 65 percent of the former but in none of the latter. About 50 percent of the ingested microfilariae reached the thorax in (2 strains) and in , but only about 2 percent in (2 strains). Yet infective larvae developed in 4 percent of the latter species. They developed in 3 percent of , but not in a New Orleans strain of or in .
