Analysis of occurrence characteristics of rice planthopper in Chongming District
()
Abstract:
In this paper, the occurrence characteristics of rice planthoppers in Chongming District from 2010 to 2016 were investigated. The results showed that white-backed planthoppers were the most common, followed by grey planthoppers and brown planthoppers. The occurrence of white-backed planthopper varies greatly from year to year, most of which occur in the third (1) generation. The three (1), four (2) and five (3) generations are the main damage generations of the brown planthopper. Since 2011, the occurrence of the brown planthopper has been decreasing year by year. In recent years, the occurrence of brown planthopper was significantly lower than that of grey Planthopper and white-backed planthopper. The occurrence of brown planthopper in six (4) generations was the most, while that in three (1) generations was the least.
