Effect of eastern equine encephalomyelitis virus on the survival of Aedes albopictus, Anopheles quadrimaculatus, and Coquillettidia perturbans (Diptera : Culicidae)

Tho effect of eastern equine encephalomyelitis (EEE) virus on the survivors hip of Aedes albopictus (Skuse), Anopheles quadrimaculatus Say, and Coquill ettidia perturbans (Walker) was determined experimentally. Female mosquitoe s were allowed to feed on EEE viremic chicks, and survival rates were compa red for infected and uninfected mosquitoes. Additionally, the survival of f emale Cq. perturbans and An. quadrimaculatus intrathoracically (IT) inocula ted with EEE was compared with controls receiving diluent inoculations. Inf ection with EEE significantly reduced survival in Cq. perturbans compared w ith uninfected individuals in per os infection experiments. IT infections o f Cs perturbans did not reduce survival when compared with diluent inoculat ed groups. In contrast, infection with EEE did not affect the survival of A e. albopictus after per os infection or An. quadrimaculatus after either IT or per os infections.
