Abstract

Summary

A strain of jungle yellow fever virus was maintained by alternate passage through marmosets and for seven cycles, after which passages were voluntarily discontinued.

A comparison was made between the efficacy of and as vectors of the virus, by submitting the two species to the same experimental conditions and by testing the mosquitoes individually through allowing them to feed upon baby mice at varying periods following the infective meal.

It was found that under the imposed experimental conditions 72 of 164 and 38 of 163 transmitted the virus, thus giving a transmission of 43.9 and 23.3 per cent respectively, or an index of 0.53 for as compared with an assumed index of 1 for .
