Authors: ABDUL AZİZ KHAN, SYED WAQAR ALİ RİZVİ

Abstract: Results of no-choice and choice feeding tests against Bandicota bengalensis showed that bromethalin is highly toxic and efficacious rodenticide. However, its susceptibility differed between sexes. In no-choice test minimum time of cent-percent mortality was 1.2 days (range 1-2). The amount of toxicant consumed per rat resulting in complete mortality was 4.92±0.78 and 5.09±0.22 mg/kg in female and male rats respectively. In choice tests, mean days to death was 2.1 (range 1-4 days) and the amount of toxicant consumed per rat averaged 5.56±0.30 mg/kg. The latency period exceeded 210 minutes of the poisoning.
