This Gravid trap is designed to collect Culex mosquitoes and powered by 4 D-cell batteries. The trap’s attractant uses a solution that attracts female mosquitoes seeking an ovipositional site. This solution can be made by infusing hay or similar organic materials.
The trap is portable and can be set wherever required.
Gravid traps are intended primarily to monitor local Culex mosquito populations, the primary vector for West Nile Virus (WNV).
Using “stagnant” water – 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.
