Abstract: Rodents are economically important organisms and of them some are reported to be serious pests destroying crops, fruit gardens, orchards and stored food grains. In the present study under laboratory conditions the preference of chosen grains viz., paddy, pearl millet, ragi, green gram, black gram and bengal gram (in two forms viz., Germinated and Non Germinated) by both sexes of four species of rodents such as Bandicota bengalensis, Millardia meltada, Mus booduga and Rattus rattus were studied with two choice and multiple choice tests. These rodent pests were also subjected to toxicity tests (acute rodenticide: 1.5% and 2% Zinc phosphide and and chronic rodenticide: Bromadiolone (0.005%); under no choice and choice tests) by using their preferred grains as a bait base. The results indicate that in two choice tests that all four species of rodent pests preferred to consume more quantity of both germinated cereals and pulses over non-germinated forms and the difference between them were statistically significant (plt0.01). Under multiple choice tests, the highest preference by all the four species of rodent pests was for green gram, pearl millet, ragi and paddy. Further, by considering the cost of each of these four grains, any one among them which is the cheapest, could be recommended to be used as a bait base for the control of all four species of selected rodents under field conditions. The results on acute toxicity (zinc phosphide) and chronic toxicity (bromadiolone 0.005%) produced cent percent mortality of among most of the test animals (all four species of rodents) under nochoice and choice tests. Based on laboratory evaluation results on acute and chronic toxicity studies, the three germinated cereals were further evaluated under field conditions in the chosen crop fields (Samba season paddy crop, Black gram, Sunflower and Cotton). Of the two rodenticides used in the present study for the control of rodent pests in Samba season paddy crop fields
