title: Field evaluation of repellents containing deet and AI3-37220 against Anopheles koliensis in Papua New Guinea.
abstract: The repellent 1-(3-cyclohexen-1-yl-carbonyl)-2-methylpiperidine (AI3-37220) was compared with 2 formulations of diethylmethylbenzamide (deet) for its effectiveness in protecting 4 humans against the bites of Anopheles koliensis mosquitoes at a village in Central Province, Papua New Guinea. A mean of 77.2 +/- 10.5 bites/human/10 min of An. koliensis was collected on ethanol-treated (control) volunteers, a much higher density than most previous studies with Anopheles sp. mosquitoes. The protection provided by all repellents did not last long. Both 25% A13-37220 in ethanol and a formulation containing 35% deet in a gel provided >95% protection for only 2 h. A formulation of 25% deet in ethanol provided only 93% protection 1 h after repellent application and 39% protection 5 h after application.
