Evaluation of coumatetralyl against two predominant murid species

Abstract
SUMMARY: 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.
