| Abstract: | Nilaparvata lugens（Stal）is a major pest in Hezhou rice district, which has the features of fast reproduction and strong pesticide-resistance etc. so that it is hard to control. The factor impacting the insect population is mainly the weather. Based on the field survey, literature consultation and reference to local weather observation data, the harm conditions of the insect＇s occurrence are analyzed to provide control warrant. The analysis results show that the weather conditions in May 2007 are favorable to fast field growth of the insect so that the harm in that year is heavy. |
