The insect was first found in Hainan and Guangdong in 1992, posing a serious threat to vegetable production. Since the city was first discovered in Yueqing in 1995, the municipal Science and Technology Commission promptly initiated the project and led by the City Plant Inspection Station and the City Vegetable Science Research Institute. From the autumn of 1995 to 1997, the research on the occurrence rules and prevention and cure techniques of the leaf blotches was carried out.
