The persistence of Bacillus pyocyaneus in pupae and imagines of Musca domestica raised from larvae experimentally infected with the bacillus

Abstract

In the course of an inquiry into the relation between the bionomics of certain insects and epidemic disease upon which I am engaged, the following question suggested itself to me. In the event of a larva becoming bacterially contaminated by means of its food, is it possible that the resulting pupa and imago will still be infected? The only previous work bearing upon this question with which I am acquainted is that of Faichnie, who writes:
