【摘要】 为了解最近几年广西贺州市稻纵卷叶螟田间发生动态，探寻适合贺州市的稻纵卷叶螟监测方法，笔者在2020—2022年采用田间赶蛾法进行了稻纵卷叶螟发生动态监测试验，并测试了田间赶蛾法、性诱法、灯诱法三种方法的监测效果。结果表明：在监测期内，2020年稻纵卷叶螟发生最重，2021年次之，2022年最轻，5月下旬至6月初为发生高峰期，发生严重程度与当年气候条件紧密相关。三种监测方法中，田间赶蛾法捕获的虫量最大，但峰次少且峰值不明显；性诱法诱捕稻纵卷叶螟虫量较多且峰次多，峰值明显，诱捕峰期与田间虫量高峰期基本吻合；灯诱法诱捕的虫量最少且峰次少、峰值不明显。因此，建议贺州市在条件允许的情况下采用性诱法或性诱法结合田间赶蛾法监测稻纵卷叶螟发生动态，利于提高测报效果的准确性及时效性，也符合发展智慧农业的需求。更多还原

【Abstract】 To understand occurrence dynamics of rice leaf roller(Cnaphalocrocis medinalis) in field in Hezhou, Guangxi in recent years, and to find out suitable monitor methods for it. From 2020to 2022, rice leaf roller occurrence monitoring and analysis were conducted using moth repel method in field. At the same time,comparing experiment of moth repel method in field, sex trapping method and light trapping method were taken to find a suitable one. The results showed that the rice leaf roller occurred the most seriously in 2020, followed by that in 2021 and 2022. Rice leaf roller occurrence peaked from late May to early June, and its severity was closely related to the climate of that year. The comparison results of 3 monitoring methods showed that: when using moth repel method in field, the number of rice leaf rollers caught was the largest, but occurrence peaked less and peak value was not obvious; when using sex trapping method, the number of caught rice leaf rollers were large, occurrence peaked more times and peak value was obvious, and peak period during trapping was basically consistent with that in field; when using light trapping method, the number of caught rice leaf rollers was the least with less peak times and not obvious peak value. Therefore, if conditions permit, using sexual inducement method or sexual inducement combined with moth repel method in field is suggested to monitor occurrence dynamics of rice leaf roller in Hezhou, which is conducive to improve accuracy and timeliness of prediction and also meets the needs of smart agriculture development.更多还原
