Adult population of Anoplophora malasiaca was studied by the capture-recapture method in a citrus orchard. The population parameters were estimated by the Jolly-Seber method. Adults emerged during June and July, mainly in June, and the total estimated number of those joining the population (with males more numerous earlier than females) was larger than that of observed emergence holes. This suggests that immigration occurred early in the emergence period. The population might have attained a peak in late June or early July if chemicals had not been applied, and survival rates were high during both months without chemical treatment. Effects of insecticide application on the survival rate were variable and not sufficient in some cases. Overall sex ratio was approximately 1 : 1.
