The BG-GAT trap was developed by Dr. A.E. Eiras from the Universidade Federal de Minas Gerais, Belo Horizonte, Brazil and Prof. Scott Ritchie from the James Cook University, Cairns, Queensland 4870, Australia. Publications: Eiras, A.E., Buhagiar, T.S., and Ritchie, S.A. (2014): Development of the Gravid Aedes Trap for the capture of adult female container-exploiting mosquitoes (Diptera: Culicidae).
Function Female mosquitoes are attracted by water and oviposition cues and enter the transparent chamber through the funnel. Once in the chamber mosquitoes try to escape through the translucent windows where they are exposed to oil/insecti- cide.

Insert the funnel in the chamber [F11]. Rotate the funnel clockwise to secure it [F12]. Mount the trap by placing the funnel and transparent chamber on the black, water filled trap bucket [F13].
F5 - F10. Positioning The black colour of the BG-GAT attracts mosquitoes from some distance. So, the trap needs to be placed where it is readily visible, but protected from rain. Please do not hide the BG-GAT in the bushes! Even though rainfall does not damage the trap, there are some negative effects of rain: •...
