A DEVICE FOR DETECTION OF RESIDUAL ACTIVITY OF BETA-CYFLUTHRIN (RESPONSAR 12.5% SC) AS A NEW PYRETHROID ON DIFFERENT SPECIES AGAINST BLATELLA GERMANICA (ORTHOPTERA: BLATTELLIDAE)
This study was designed to evaluate the efficacy of beta-cyfluthrin (Responsar 12.5% SC), against a standard susceptible strain of German cockroach, Blattella germanica, using three different dosages, at three different exposure times, on two types of surface, parlous (mosaic) and non parous (glasse...
