Abstract/ Executive Summary:

Abstract: The effectiveness of 0.005% brodifacoum poison bait for controlling shrew was carried out at Vertebrate Pest division, BARI. Out of ten shrews, 8 shrews were found dead inside the laboratory. The mortality of shrews was 80%. The average day to death was 4.5 and the average bait consumption was 89.63g/day/shrew.

Keywords: Efficacy, Brodifacoum, anticoagulant, rodenticide, control, house shrew, Suncus murinus.

Objectives:

To determine the efficacy of formulated brodifacoum poison bait for controlling shrew.

Methodology:

Preparation of poison bait: 0.005% brodifacoum poison bait was prepared for controlling shrew. Cooked rice was taken as a carrier material. Some vegetable oil was used to make the bait palatable and well mixing of poison. For the preparation of 100 g 0.005% brodifacoum poison bait, 2 ml brodifacoum (0.25% a.i.) was mixed with 8 ml vegetable oil. This mixture was added with 90g cocked rice in a cup. Evaluation of 0.005% brodifacoum bait: Only "no-choice" feeding test was conducted using 0.005% brodifacoum poison bait. Ten shrews were selected for this study. The average body weight was 89.63g. The animals were maintained in individual cages (17x24x42 cm) for a minimum of 7 days before testing. Water was provided ad libitum from glass or plastic bottles. Hundred grams of poison bait was placed in each cage. The poison bait was offered to the rats for one day and normal cooked rice was provided for rest of the fifteen days after which the experiment was terminated. Daily observation were made to record the bait consumption and mortality status.

Achievement/Findings:

Efficacy of poison bait: The effectiveness of 0.005% concentration of brodifacoum bait for shrew control is presented in . Two male and one female shrew stopped their activity after 3rd day of bait application in cage no. 3, 7 and 8. On the fourth day, four shrews (3 female and 1 male) were found dead in cage no. 1, 4, 5 and 9. One female shrew was alive up to 10 days and found dead on 11th day in cage no. 6. One male and one female shrew were alive up to the end of the experiment in cage no. 2 and 10. In this experiment, the mortality rate of house shrew was 80% and the average day to death was 4.5 (Table 9). The average poison bait consumption was 39.08 g/shrew/day. The experiment should be repeated before giving any recommendation.
