In the large cage trials, in which the CO2baited Mega-Catch™ trap and the Mosquito Magnet™ Pro were in direct competition in the same cage, the Mega-Catch™ captured almost twice as many Ae. aegypti as the Pro. In the one test with Oc. taeniorhynchus... the Pro caught slightly more mosquitoes than the Mega-Catch™ trap. The opposite occurred in the one test with Cx. quinquefasciatus. More direct competition studies between these two trap types are needed with a greater diversity of species. Based on the performance of the Mega-Catch™ trap without CO2, when tested alone in the cage, it would be very interesting to conduct direct competition between this configuration and the Pro trap in future cage studies.
