Abstract:
This research was conducted to determine biological activity of Phantom SC (chlorfenapyr) on wood, concrete, and vinyl surfaces. The experimental design was a 3 x 3 x 3 factorial (3 treatments, 3 surfaces, and 3 insect-pests). Each experimental unit consisted of a rigid-plastic cage (109 x 49.5 x 17 cm) with wood, concrete, or vinyl surfaces affixed to the bottom. The surface in each arena was sprayed with 0.37 or 0.50% chlorfenapyr. Insect populations were confined to pre-assigned units and covered with a lid. Insect mortality was observed for 28 and 5 days in cockroach and house fly experiments, respectively. Phantom SC (0.5%) yielded 100, 96, and 90% mortality in American cockroaches on wood, vinyl, and concrete surfaces, respectively. Chlorfenapyr 0.5% provided 100, 97, and 85% mortality in Oriental cockroaches on concrete, wood, and vinyl surfaces, respectively. Chlorfenapyr 0.37 and 0.5% caused 100% mortality in house flies on all treated surfaces after 4.5 days. Residual efficacy trials (29-42 days after initial treatment) with chlorfenapyr 0.5% against American cockroaches produced 87, 84, and 58% mortality on cement, vinyl, and wood surfaces, respectively. Our data indicates that Phantom SC is very efficacious on wood, concrete, and vinyl surfaces against cockroaches and house flies.
