The experiment was carried out at laboratory of Vertebrate Pest Division, BARI, Gazipur to evaluate the rodentical properties of ‘Urmoi’ Sapium sabiferum for rodent control. No mortality was observed from urmoi treated bait. The highest consumption (7.56 g/rat/day) was recorded from water extract + wheat flour bait.

To evaluate the rodentical properties of ‘Urmoi’ Sapium sabiferum for rodent control
Malarials and Methods
The experiment was conducted at the laboratory of vertebrate Pest Division, BARI, Gazipur. Bandicota bengalensis were kept under the laboratory condition for at least 3 weeks for acclimatization before starting the experiment. All animals were starved for 6 hours before applying the treatments.Fresh urmoi fruits were collected from Nolcity, Zalokhali. Fruits were washed in running water and dried in air. Finally dried fruits were ground in a grinding machine.
The following treatments (bait) was used for the test-
T1 = 50% urmoi fruit powder + 50% wheat flour
T2 = Acetone extract + wheat flour
T3 = Water extract + wheat flour
Preparation of plant extract
Acetone extract
50 g of grinded urmoi fruit was mixed with 200 ml of acetone in a 250 ml beaker. The mixture was stirred for 30 minutes and was allowed to stand for 24 hours. In the next day the mixture was again stirred for 30 minutes and allowed to stand for next 24 hours. The filtrated was boiled in a water bath to evaporate the solvent.
Water extract
50 g of grinded urmoi fruit was mixed with 200 ml water in a 250 ml beaker. The mixture was stirred and allowed to stand for 48 hours and boiled for 15 minute and then filtered through muslin cloth.
Bait application
Bait was offered to the rat for consecutive 3 days. Each of the caged rats was offered 20 g of bait in food cup everyday and all other food material were removed from the cage. Observation was taken daily. Sex, body weight were recorded. Water was supplied ad libitum. Day to death and number of dead rats were recorded.
VPD Annual Report-2005-06
Twenty thousands
No mortality was observed from urmoi treated bait. The average highest consumption (7.56 g/rat/day) was recorded from the treatment T3 (water extract + wheat flour) bait. No visible physical or behavioral disorder was found after consumption of urmoi bait but slightly sluggish movement of rat in treatment T3 was observed.
