Evaluation of coumatetralyl against two predominant murid species.
Coumatetralyl was evaluated in the laboratory against Bandicota bengalensis and Rattus rattus. Feeding tests with 0.0375% coumatetralyl baits produced 100% mortality after a single day feeding period in B. bengalensis and after a 10-day period in R. rattus. The anticoagulant bait is less palatable in comparison to plain bait. In the case of R. rattus, LFP50 and LFP98 and their 95% confidence limits were 3.89 (2.62-5.77) days and 11.22 (6.1-20.65) days respectively. Median period of survival and its 95% confidence limits of B. bengalensis and R. rattus were 4.7 (3.85-5.7) days and 11.2 (9.33-13.44) days respectively.
