Abstract fleshlight automatique Background Resting mosquitoes can easily be collected using an aspirating device.The most commonly used mechanical aspirator is the CDC Backpack aspirator.Recently, a simple, and low-cost aspirator called the Prokopack has been devised and proved to have comparable performance.
The following study evaluates the Prokopack aspirator compared to the CDC backpack aspirator when sampling resting mosquitoes in rural Tanzania.Methods Mosquitoes were sampled in- and outdoors of 48 typical rural African households using both aspirators.The aspirators were rotated between collectors and households in a randomized, Latin Square design.
Outdoor collections were performed using artificial resting places (large barrel and car tyre), underneath the outdoor kitchen (kibanda) roof and from a drop-net.Data were analysed with generalized linear models.Results The number of mosquitoes collected using the CDC Backpack and the Prokopack aspirator were not significantly different both in- and outdoors (indoors p = 0.
735; large barrel p = 0.867; car tyre p = 0.418; kibanda p = 0.
519).The Prokopack was superior for sampling of drop-nets due to its smaller size.The number mosquitoes collected click here per technician was more consistent when using the Prokopack aspirator.
The Prokopack was more user-friendly: technicians preferred using the it over the CDC backpack aspirator as it weighs considerably less, retains its charge for longer and is easier to manoeuvre.Conclusions The Prokopack proved in the field to be more advantageous than the CDC Backpack aspirator.It can be self assembled using simple, low-cost and easily attainable materials.
This device is a useful tool for researchers or vector-control surveillance programs operating in rural Africa, as it is far simpler and quicker than traditional means of sampling resting mosquitoes.Further longitudinal evaluations of the Prokopack aspirator versus the gold standard pyrethrum spray catch for indoor resting catches are recommended.
