Mango is attacked by many insect pests which reduce the quality and productivity of the crop. Among the insect pests attacking mango plant, white mango scale is the most devastating insect pest. It is a new insect pest and a major problem of mango production in Ethiopia. In a short period of time, the insect invaded nearly all of Ethiopia's mango-growing regions, and the country was placed on the list of countries affected with the new white mango scale. Its polyphagous behavior and sucking the plant sap, the insect pest severely harms mango shoots, twigs, leaves, branches, and fruits, which results in significant fruit quality and quantity losses. The insect's hard white scales make it difficult to control with chemical pesticides, in addition to other uncontrolled activities. Although no accepted chemical control methods for the white mango scale are successful, other management strategies for the pest include cultural, biological, chemical, and integrated pest management. White mango scale damage had an impact on the economy, society, environment, and other factors. Therefore, directly coordinated actions are required against this uncontrolled white-scale dissemination and the harm it causes in mango growing region of the world.
