Population Dynamics of Characoma stictigrapta HMPS. (Lepidoptera: Noctuidae), on Cocoa in Ghana

(1) Population dynamics of Characoma stictigrapta caterpillars a pod and leaf feeding pest of cocoa in Ghana, was studied. (2) The caterpillars were found on pods throughout the year and had aggregated distribution. Populations on the flush leaves and other vegetative parts of the cocoa tree did not occur all the year round, being dependent on the availability of the leaves. (3) The dispersal pattern of the caterpillars among pods determined the pattern and nature of damage on pods, which was also aggregated. (4) The natural enemies of the caterpillars and heavy rains appeared to keep the population low at certain times of the year. (5) Populations of natural enemies also fluctuated throughout the year being influenced at least by rain
