The mid-1950s due to the extensive use of organophosphate pesticides, resulting in ecological disorders, environmental pollution and resistance. Gradually in the province generally occur, and become the highest cost control pests. In order to seek effective integrated control measures, reduce the number of spraying and improve economic efficiency, based on the study of the life history, living habits and the growth and decline of citrus red spider, the experiment was carried out in the fruit trees of Jiangjin in 1980-1984 Field into
