Abstract
Abstract The reproductive biology and the population structure of Bandicota bengalensis was studied from a regular monthly collection, made in the Paddy fields around Bangalore, Karnataka from 1982 to 1984. The bandicoot exhibits a seasonal reproductive activity lasting from early August till the end of April with an anoestrous period between March and July. Correlatively, the reproductive glands and the sex accessories show seasonal changes in their weights. The peak reproductive activity was seen during September, October and November, when the prevalence of pregnancy was 0.81 with a mean litter size of 7.1. Analysis of data compared with temperature and rainfall showed that variation in breeding activity could be due to rainfall and the availability of food in the environment. The annual reproductive rate is calculated to be 67 young per female per breeding season. The bandicoots exhibit lesser body weights during summer months, and greater body weight coincides with the peak breeding season when the p...
