The susceptibility of Rattus rattus and Bandicota bengalensis to a new anticoagulant rodenticide, flocoumafen
SUMMARY The anticoagulant rodenticide flocoumafen was evaluated against Rattus rattus and Bandicota bengalensis , In no-choice 24 h feeding tests 100% mortality occurred at 0·00125% concentration of the poison in the bait in the case of B. bengalensis and at 0·00375% in R. rattus . Feeding of 0·0025...

| Summary: | SUMMARY The anticoagulant rodenticide flocoumafen was evaluated against Rattus rattus and Bandicota bengalensis , In no-choice 24 h feeding tests 100% mortality occurred at 0·00125% concentration of the poison in the bait in the case of B. bengalensis and at 0·00375% in R. rattus . Feeding of 0·0025% poison bait in 1-day, no-choice and 2-day choice tests resulted in 60% and 75% mortality of R. rattus , respectively, and 100% of B. bengalensis . The differences between the consumption of plain food in the pretreatment period and of poison bait in no-choice tests were non-significant, except in one case. The rodents consumed significantly more ( P < 0·01) poison bait than the plain alternative in the choice trials. Median period of survival and its 95% confidence limits of R. rattus and B. bengalensis , at the 100% mortality dose levels of the poison, were 6·3 (5·04–7·88) and 6·2 (4·92–7·81) days respectively. |
