The knockdown and lethal efficacies of five aerosol formulations including Combat Speed ® (AIs: 0.1 % imiprothrin and 0.3% cyphenothrin), Raid Power ® (AIs: 1.0% pyrethrin and 0.2% permethrin), Home Keeper ® , (AIs: 0.2% tetramethrin and 0.3% permethrin), Super Killer ® (AIs: 0.32% tetramethrin and 0.08% bioresmethrin), and Perma Kill‐K ® (AIs: 0.3% dichlorvos and 0.1% tetramethrin) against five strains of the German cockroach, Blattella germanica (L.) were assessed. The results show that the mean value of KT 50 (5.4 sec.) of Combat Speed ® was 4.5 and 3.1‐folds lower than those of Perma Kill‐K ® and Home Keeper ® , respectively. The mean value of KT 90 (9.0 sec; slope = 10.02) of Combat Speed ® was 3.8 to 5.8‐folds lower than Perma Kill‐K ® , Supper Killer ® and Home Keeper ® . As lethal effects, the mean value of LT 50 (17.3 sec.) of Combat Speed ® was over 26 folds lower than Supper Killer ® and Perma Kill‐K ® . The mean value of LT 90 (32.9 sec.) of Combat Speed ® was 37.4 and 15.1‐folds lower than those of Supper Killer ® and Perma Kill‐K ® , respectively. In general, Combat Speed ® and Raid Power ® were considered the insecticide aerosols with faster knockdown and higher lethal effects than Supper Killer ® , Perma Kill‐K ® , and Home Keeper ® against five strains of German cockroaches in Korea. Also, the knockdown and lethal effects of Supper Killer ® , Perma Kill‐K ® , and Home Keeper ® were highly variable depends on the strains.
