Gravid traps are important tools for disease monitoring and for research on mosquito ovipositional behavior. Two experiments were conducted to evaluate a 2% nonanal lure in gravid mosquito traps in Ifakara, Tanzania. The 1st experiment focused on whether water was needed in the pan below the trap for the nonanal lure to be effective. Read More

The effectiveness of traps baited with (5R,6S)-6-acetoxy-5-hexadecanolide (the synthetic oviposition pheromone) and grass infusions in sampling a population of gravid Culex quinquefasciatus Say was conducted in Muheza, Northeast Tanzania. A counterflow geometry (CFG) trap baited with pheromone and set outdoors, adjacent to a pit latrine building, collected more gravid Cx. quinquefasciatus than a CDC trap baited with pheromone and operated without light.

Gravid traps are useful tools for monitoring vector-borne pathogens in mosquitoes, particularly for those pathogens transmitted by Culex quinquefasciatus Say. One of the primary challenges in the use of gravid traps is the necessity of the inclusion of an oviposition attractant, usually an infusion of organic material, which changes in attractiveness over time. However, a standardized lure, using nonanal and trimethylamine (N + TMA), has been developed and is commercially available. Read More

Background: Although several studies have suggested that gravid traps might be useful for collection of mosquitoes, particularly Culex quinquefasciatus, to monitor transmission of the nematode Wuchereria bancrofti (xenomonitoring), there has not been a study to see which of the currently available gravid traps is most effective in endemic areas. The present study evaluated the comparative efficacy for collection of Cx quinquefasciatus of four commercially available gravid traps: the CDC, Frommer Updraft, Reiter-Cummings and Harris County traps.
Method: Trap evaluations were conducted in two locations in Tanzania, Ifakara and Tanga. Read More
