Abstract
Mastomys natalensis is among the most important rodent pests in Sub-Saharan Africa. This study investigated
the population dynamics and breeding patterns of this mouse in system rice intensification (SRI) and in conventional
cropping systems in irrigated rice ecosystem in eastern Tanzania. The Mastomys natalensis population varied
with years and season, but not with either SRI or conventional cropping system which would be expected as the
all fields are in the same area. The highest population peak was observed during the dry season i.e., August to
September. Breeding patterns of this rodent pest was not influenced by the cropping system or season, indicating
that M. natalensis is sexually active throughout the year and does not be affected by the rice production systems.
Regular control and sustainable operations, such as the use trap barrier system (TBS), are therefore essential if the
populations are to be kept within tolerable limits.
