A duplex cone trap for the collection of adult Aedes albopictus.

A duplex cone trap was developed for the collection of Aedes albopictus adults. This device employs carbon dioxide and a visual attractant to draw mosquitoes into an air current created by a 6-volt battery-powered fan. In comparison with 8 other adult mosquito traps, the duplex cone was most effective in capturing Ae. albopictus females. A greater diversity of mosquito species was caught in the duplex cone trap compared with the other traps tested. In an experiment comparing the duplex cone trap with human biting collections, this trap proved to be an efficient and sensitive means of monitoring Ae. albopictus population changes.
