摘要：

褐飞虱(Nilaparvata lugens)、白背飞虱(Sogatella furcifera)、稻纵卷叶螟(Cnaphalocrocis medinalis)是为害水稻的迁飞性害虫,统称水稻“两迁”害虫。多年来,淳安县的水稻“两迁”害虫为中等到大发生程度,若不及时防治将严重影响水稻生产。为科学合理指导当地“两迁”害虫的测报与治理,本研究根据“预防为主,综合治理”的原则,于2022—2024年通过田间系统调查法,总结了淳安县水稻“两迁”害虫的发生特征及成因,并提出相应的防控建议。结果表明,2022—2024年淳安县稻飞虱、稻纵卷叶螟的发生程度为总体中等发生,局部大发生。同时,当地通过将化学防控与飞防技术相结合,取得了显著的“两迁”害虫防治效果,防治面积占一年一季水稻总种植面积的96%。综上,“两迁”害虫的发生程度受到当地水稻栽培现状、气象条件、害虫抗药性、飞防技术等多方面因素的影响,需结合数据开展进一步分析。在防治举措的选择上,建议推广植保无人机技术防治病虫害,并采取农业、物理、生物等绿色防控措施代替化学农药的使用,保护生态环境,建立“两迁”害虫防控长效机制。

Abstract:

The migratory rice pests Nilaparvata lugens, Sogatella furcifera, and Cnaphalocrocis medinalis in Chun'an County occurred at a moderate to high level over multiple years. If not controlled in time, it will seriously affect rice production. Based on the principle of “prevention-first, integrated control”, this study summarized the occurrence characteristics and causes of migratory rice pests in Chun'an County from 2022 to 2024 through field system investigation methods, and put forward corresponding control suggestions. Results demonstrated that rice planthopper (N. lugens and S. furcifera) and C. medinalis infestations reached moderate levels countywide during 2022-2024, with localized severe outbreaks. Besides, the local area has achieved remarkable results in the control of migratory rice pests by combining chemical control with aerial spraying technology, with the controlled area accounting for 96% of the total annual rice planting area. In summary, the occurrence degree of migratory rice pests was influenced by multiple factors such as the current status of local rice cultivation, meteorological conditions, pest resistance, and aerial spraying techniques. Further analysis should be conducted in combination with the data. In addition, in terms of the selection of prevention and control measures, it is suggested to promote the use of plant protection drones to control pests and diseases, and adopt green prevention and control measures such as agricultural, physical and biological ones to replace the use of chemical pesticides, protect the ecological environment, and establish a long-term mechanism for the prevention and control of migratory rice pests.
