EVALUATION OF AN AEROSOL FORMULATION CONTAINING CYFLUTHRIN AGAINST THREE SPECIES OF STORED-PRODUCT INSECTS

Abstract

An experimental formulation containing cyfluthrin (Laser®) was evaluated against two commercial products for control of adult almond moth, Cadra cautella (Walker), adult confused flour beetle, Tribolium confusum (DuVal) and black carpet beetle, Attagenus unicolor (Brahm) (= A. megatoma F.) larvae. When Laser was released for 2.5 and 5.0 sec into test chambers and almond moths were exposed for 3 h, mortality was 97 and 99%, respectively. These percentages were significantly greater than the mortality provided by one of the commercial formulations (79 and 89% for 2.5 and 5.0 sec, respectively). There were no differences between the three formulations at release times of 10 and 20 sec and exposure times of 6 and 18 h. None of the formulations killed either of the two beetle species, but the percentage knockdown for Laser was significantly greater than knockdown provided by either commercial product.
