Comparison of the Centers for Disease Control and Prevention-Backpack and Insectazooka Aspirators for Sampling Aedes polynesiensis in French Polynesia

The efficiency of the recently developed handheld InsectaZooka™ (IZ) aspirator was compared to that of the Centers for Disease Control and Prevention-Backpack (CDC-BP) aspirator by conducting human bait collections on 2 islets (locally called motus) of the atoll of Tetiaroa, French Polynesia. Abundance of mosquitoes was compared between the wind-exposed and wind-protected sides of each motu to measure the effect of wind on mosquito distribution. The number of host-seeking Aedes polynesiensis mosquitoes collected on the 2 motus with either sampling device was not significantly different. Collection of male mosquitoes was low irrespective of the type of aspirator used. Wind had an effect on mosquito distribution, as females were more abundant on the protected sides of both motus. The IZ aspirator is a lighter and equally efficient alternative to the CDC-BP aspirator for collecting Ae. polynesiensis.
