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. There was no significant difference between the numbers of gravid females of Culex quinquefasciatus collected in traps using a nonanal lure either with or without water. The 2nd experiment compared the lure, without water, to a grass infusion and a blank trap, without water or attractant. Significantly more mosquitoes were collected in traps with grass infusion than in traps with the other attractants, which were not significantly different from each other. Although more mosquitoes were collected in traps with grass infusion, substantial numbers were also collected in traps with the nonanal lure and unbaited traps. © Copyright © 2014 by The American Mosquito Control Association, Inc.
