Abstract

In 2021, widespread defoliation of Pouteria obovata occurred in the Co To Island, Vietnam. The damage incidence from defoliation ranged from 23 to 82%, and the average damage index was from 0.4 to 3.1. Based on morphological and molecular data, this paper establishes Achaea serva (F.) as a serious new pest of P. obovata. This pest should be included in future forest health monitoring programs in coastal Vietnam to determine its spread, host range and pest status.
