Abstract:

Study on the occurrence pattern and its dynamic monitoring of apple pests in Luochuan County, and gave a great practical guiding significance for orchard pest ecological regulation and management in Weibei Loess Plateau. In 2001—2010, the dynamic monitored apple pests were collected from Luochuan apple orchard by the methods of laboratory test and field experiment. The results showed that the occurrence pattern and hazard assessment of apple pests differed annually in the areas. Therefore, an annual and long-term dynamic monitoring was necessary to provide exact information for ecological regulation of apple pests.
