An investigation was carried out to find out the antifeedant effect of botanicals viz., Carica papaya, Solanum khasianum, Ananas comosus, Moringa oleifera, Azadirachta indica against Rattus rattus under choice and nochoice feeding trials. The consumption of treated bait by the rats of both the sexes under choice test was reduced in comparison to no-choice test because of availability of an alternate plain food along with the treated bait. The antifeedant index of M. oleifera against both the sexes of R. rattus was significantly higher i.e. (67.1% in male and 66.2% in female) followed by S. khasianum (56.2% in male and 57.1% in female) under choice feeding trial. The highest antifeedant index (64.7% in male and 66.6% in female) was also recorded with M. oleifera treated bait followed by S. khasianum (60.6% in male and 61.1% in female) under no-choice feeding trial. Botanicals viz. M. oleifera and S.khasianum had shown promising antifeedant property against both sexes of R. rattus under both choice and no choice feeding trials.
