Rodents are one of the important vertebrate pests directly related to destruction of crops belongings of man and animal besides responsible for spread of many diseases. The study was under taken at three villages of Chikkaballapura District in the state of Karnataka to know the influence of extension intervention on rodent density and infestation on various crops. The results indicated that in a village with an extension intervention viz. group discussion, demonstration and free distribution of rodenticides resulted in significant reduction of rodent density (67.70%) and incidence (77.59%) on various crops. However, in another village where one day training workshop on rodent management was given without supply of any inputs, the rodent density (27.47%) and rodent damage (17.43%) reduction was moderate. Whereas in control village where there was no extension intervention the rodent density and damage increased by 42.60 and 33.47 per cent, respectively. This clearly highlight the importance of extension intervention viz. group discussion, training programmes and demonstrations in the management of rodents.
