This Gravid trap, powered by a 6 volt DC power source, is designed to collect Culex mosquitoes and can easily be set wherever required. The trap’s attractant contains a solution that attracts to female mosquitoes seeking an ovipositional site. This solution can be made by using a hay infusion or similar organic materials.
The trap operates by creating an upward current of air from within the confines of the pan, blowing mosquitoes into the collecting bag during their pre-oviposition behavior.
Gravid traps are intended primarily to monitor local Culex mosquito populations, the primary vector for West Nile Virus (WNV). Using “stagnant” water (infused with hay, grass, or similar organic material) as an attractant, female Culex mosquitoes are drawn to this trap to lay their eggs.
Trapped adult females can then be used for WNV testing. In addition to their ability to monitor for WNV, Gravid traps are also economical and highly portable.

While mosquito-borne diseases threaten human health worldwide, implementing an integrated mosquito management (IMM) system can go a long way toward mitigating those risks. Within the IMM network, the surveillance lever acts explicitly as a predecessor to larval or adult control…
