  • In this paper, the historical data of field survey of rice planthopper in Xiushan County, Chongqing from 2004 to 2021 were collected, and the occurrence period, amount and degree of local rice planthopper were analyzed. The results showed that the damage of rice planthopper in Xiushan County showed new characteristics. Firstly, the harm period of white-backed planthopper and brown planthopper was not consistent, and the peak periods of both were obvious. Secondly, the occurrence degree of rice planthopper showed a slight trend. Thirdly, the main damage period of rice planthopper showed an earlier trend. Fourthly, the occurrence and damage of rice planthopper in different ecological regions of the county were obviously different. The occurrence and damage in plain hilly area was heavier than that in low mountain area, and the damage in low mountain area was heavier than that in high mountain area. This study further explained the basic reason of occurrence and change of rice planthopper in Xiushan County, including special geographical location, climatic conditions, techniques for rice cultivation management and prevention and control of rice planthopper. Finally, the prevention and control strategies of rice planthopper were put forward according to generation prediction, regional cooperation monitoring and ‘white pressure and brown control’ monitoring to provide a basis and reference for the precise prevention and control of rice planthopper.

Abstract: In this paper, the historical data of field survey of rice planthopper in Xiushan County, Chongqing from 2004 to 2021 were collected, and the occurrence period, amount and degree of local rice planthopper were analyzed. The results showed that the damage of rice planthopper in Xiushan County showed new characteristics. Firstly, the harm period of white-backed planthopper and brown planthopper was not consistent, and the peak periods of both were obvious. Secondly, the occurrence degree of rice planthopper showed a slight trend. Thirdly, the main damage period of rice planthopper showed an earlier trend. Fourthly, the occurrence and damage of rice planthopper in different ecological regions of the county were obviously different. The occurrence and damage in plain hilly area was heavier than that in low mountain area, and the damage in low mountain area was heavier than that in high mountain area. This study further explained the basic reason of occurrence and change of rice planthopper in Xiushan County, including special geographical location, climatic conditions, techniques for rice cultivation management and prevention and control of rice planthopper. Finally, the prevention and control strategies of rice planthopper were put forward according to generation prediction, regional cooperation monitoring and ‘white pressure and brown control’ monitoring to provide a basis and reference for the precise prevention and control of rice planthopper.
