Abstract

Abstract:

【Objective】 Rice borers are widely distributed in Guangxi and pose a serious threat to rice production. The aim of this study is to clarify the overwintering situation and spatial distribution pattern of rice stem borers in Guangxi, understand the distribution and species of rice stem borers, and provide a basis for prediction and scientific control. 【Method】 Rice stem borers were investigated in 27 cities (counties) in the northeast, northwest, southeast, southwest, and coastal areas of Guangxi, respectively. The checkerboard sampling method was employed to investigate the overwintering borers. Rice stubbles were collected and brought back to the laboratory for careful species identification and quantification of borers. The spatial distribution pattern of the borer population was analyzed. 【Result】 The results of the overwintering survey revealed that the overwintering borer species in our region included Sesamia inferens, Chilo suppressalis, Scirpophaga incertulas, and Chilotraea auricilia. Among them, the overwintering population was primarily composed of S. inferens and C. suppressalis, with S. incertulas occurring mainly in the latitude of 23°－25°. The overwintering population density of other borers did not exhibit an obvious regular distribution in our region. Spatial distribution parameters indicated that borers in other fields displayed an aggregation distribution, with the degree of aggregation increasing with density, except for S. inferens in fields 13, 20, and 22, where they were uniformly distributed. The aggregation of borers in paddy field was mostly attributed to environmental factors. 【Conclusion】 In Guangxi, overwintering borers are clustered, with dominant populations of S. inferens and C. suppressalis in the field, followed by C. auricilia, while S. incertulas occurred sporadically.

摘要：

【目的】水稻螟虫在广西广泛分布，严重威胁水稻生产，明确广西稻螟的越冬情况及其空间分布型，了解水稻螟虫的种类及分布情况，为其预测预报及科学防治提供依据。【方法】分别在桂东北、桂西北、桂东南、桂西南和沿海地区，共27个市（县）进行越冬螟虫调查，并采用棋盘式取样法，将稻桩带回室内仔细剥查鉴定螟虫种类及数量，分析螟虫种群的空间分布型。【结果】本次越冬调查结果表明，广西越冬螟虫种类有大螟(Sesamia inferens)、二化螟(Chilo suppressalis)、三化螟(Scirpophaga incertulas)和台湾稻螟(Chilotraea auricilia)，其中大螟和二化螟为优势种。三化螟主要分布在纬度23°－25°，其他螟虫在广西越冬未呈现明显规律。空间分布参数表明，除13、20和22号田块大螟呈均匀分布外，其他田块螟虫均呈聚集分布，且聚集度随密度的增加而升高。大部分田块螟虫聚集原因是由环境因素引起的。【结论】在广西，越冬螟虫呈聚集分布，大螟和二化螟为田间越冬优势种群，台湾稻螟次之，三化螟零星发生。
