| dc.description.abstract | The common Black rat, Rattus rattus wroughtoni Hinton (Rodentia: Miiridae) is a predominant pest (72.5% relative abundance) of cacao and coconut crops, along with seven other species of rodents, three species of bats and one species of shrew. The weights and measurements of head and body were significantly (P<0.01) more in males than in females. Of the total free living populations, females (54%) predominated. The highest prevalence of pregnant females, subadult populations : and high densities of R. rattus wroughtoni coincided with tne low rainfall period from September to October. Low levels of reproduction and subadult population were encountered during high rainfall periods from June to August, since rainfall had an adverse effect on reproduction of rats. | en_US |
