Reproductive potential and development stages of Bandicota indica were studied in Magway Township, Minbu (Sagu) Township, Pwintbyu Township and Kamma Township, Magway Region during the period from January to December 2017. These townships were more productive area of rice and legumes in Magway Region. B. indica appeared as the dominant species in study area and a serious pest in agriculture fields and importance to next the insect pests. Rats were caught by laying traps near the entrance of rat holes and along the prospective travel routes within the crop fields. A total of 288 rats were captured, consisting of 157 males and 131 females. The number of male rat was somehow more than the number of female rat in all four study sites but the sex ratio did not differ significantly from a 1:1 ratio. The highest number of B. indica was found in November and December during the harvesting stages of the rice as peak population of rodents in the field depended on the available food and shelter. Breeding activity was more pronounced during the growing and harvesting stages than during the fallow period. Since rodents are the major cause of heavy damage in cultivated field, there is a need to outline effective measures in order to prevent the onslaught of rodents on the crops in order to safeguard the harvest yield.
