Studies on bromadiolone resistance in Rattus rattus populations from Punjab, India.

There are several reports on development of resistance to bromadiolone in different species of rodents around the globe, however, there is no such report involving systematic study from India. Hence, present study was carried out to investigate current status of bromadiolone resistance in house rat (Rattus rattus; n=154) collected from different poultry farms (n=8) based on feeding test, blood clotting response (BCR) test and molecular characterization of VKORC1 gene. Based on feeding test and BCR test, 28% rats were suspected to be resistant.

Potential of triptolide in reproductive management of the house rat, Rattus rattus.

Mature and healthy male house rats, Rattus rattus (n= 160) were fed on bait (cracked wheat: powdered sugar, 98:2) containing different concentrations of triptolide (0.1, 0.05, 0.
