The cararnbola fruit borer, Eucosma notanthes is an important insect pest of carambola in Taiwan. The pest could lay its eggs on and damage to any stage of the fruits through a year round that cause a great economic losses of the fruit production. Present experiment is conducted to evaluate the effeciency of borer’s control by using insecticide application and paper-bag covering method. The results indicated that insecticide alone was not sufficient to suppress the borer infestation economically. Covering fruits with paper-bags although could protect the fruits from damage, but it was laborious and also caused a severe fruits falling when the action was taken during young fruit stage. Integrated the two methods by application of insecticide at 7-to 10-day intervals since fruit setting stage to the fruits growing upto about 5 cm in length, then covering the fruits with paperbags provided the highest control effeciency.
