Assessment on Economic-yield Loss Caused by Key Pests of Rice in Paddy Fields of Shandong Province--A Case in Tancheng County
摘要
Abstract
Shandong Province is the typical growing region of the single and midseason rice in China. In recent years, because of intensifying climate changes, main varieties’ renewal and cultivation institutional changes, etc, some new characteristics of the rice pests’ occurrence and outbreaks appeared in this rice growing region. In this paper, based on the observation data of the telemetry monitoring and controlling of rice pests in combination with the climate data from 1994 to 2009 in the rice growing region of Tancheng County, Linyi City of Shandong Province, the occurrence characteristics of rice pests and their economic damage (i.e., rice yield losses) were systematically analyzed, and also the efficiency of rice pests management and yield protection of the plant protection measures were assessed as well. The results indicated that there were no significant correlation between the annual mean temperature (annual precipitation as well) and the occurrence area and rice yield loss of stem borer, Chilo suppressalis (Walker) and rice plant-hopper (including the brown plant-hopper, Nilaparvata lugens Stål). While significant correlation was found between the annual mean temperature (annual precipitation as well) and the occurrence area and rice yield loss of rice leaf-roller, Cnaphalocrocis medinalis (Guenee), respectively. It was clear that the pest management of rice under climate changes could be effectively improved and enhanced through the accurate monitoring and forecasting, and through timely prevention and control against rice pests, which in turn was to ensure the food safety in production and further to safeguard the farmers' income increase.关键词
