Abstract: A study on the ecology of rodents was carried out in Wonji Sugarcane Plantation from August 2005 to March 2006. Three trapping grids were randomly selected in the sugarcane plantation based on the growth stage of the cane as- immature sugarcane plant (ISP), young sugarcane plant (YSP), and old sugarcane plant (OSP). An additional grid was selected from bushland area outside the sugarcane plantation. A total of 629 captures were made in 2940 trap nights. Out of these, 557 individuals represented eight species of rodents: Mastomys natalensis, Arvicanthis dembeensis, Arvicanthis niloticus, Stenocephalemys albipes, Pelomys harringtoni, Mus mahomet, Mus musculus, and Rattus rattus. The remaining 72 individuals represented two insectivore species; Crocidura flavescence and Crocidura fumosa. Abundance of species varied in different growth stages of the sugarcane plantation and bushland area. There was seasonal difference in the abundance of the rodents. However, species composition was the same in all the three growth stages of the sugarcane plants and in bushland area. Variation in trap success with different growth stages of the of sugarcane plantations was significant. All age groups were represented in the population of most species. Breeding was seasonal for most of the species. The pest status of rodents in the sugarcane plantation was assessed. Analysis of the stomach contents of snap trapped rodents from the plantations showed sugarcane fibers that confirm the pest status of rodents in the sugarcane plantation while monocot plants were dominant in rodents captured from bushland area. Population estimation using minimum number alive (MNA) showed decline in each trapping session.
