中文摘要:为明确四川省东部稻区稻飞虱的发生情况及规律,于2014-2018年通过灯光诱捕和田间调查的方法,以达州市达川区、大竹县和泸州市叙永县稻区为代表对川东稻区稻飞虱种群进行系统调查。结果显示:川东稻区稻飞虱优势种为白背飞虱Sogatella furcifera。灯诱条件下川东南稻区叙永县稻飞虱始见期为5月上中旬,川东北稻区达川区和大竹县稻飞虱始见期为5月底至6月上中旬;高峰期均为7月中旬至8月上旬。2014-2018年达川区、大竹县和叙永县稻区稻飞虱田间发生最严重的年份分别为2018、2014和2018年,该年田间发生总量分别为29 946、15 353和35 607头/百丛。川东南稻区稻飞虱为害中若虫数量占绝对优势,但成虫发生为害持续时间长;在达川区、大竹县和叙永县稻区稻飞虱发生最严重的年份,成虫的田间发生量分别达到4 583、5 452和16 870头/百丛。川东稻区稻飞虱整体上在2014年和2017-2018年间发生较重,且川东南稻区害虫发生较川东北稻区更严重。表明四川省东部3个稻区稻飞虱的发生量在不同年份间有很大差异,且优势种为白背飞虱,其成虫持续为害时间长。

Abstract:To clarify the population dynamics and occurrence regularity of the rice planthoppers in eastern Sichuan, light trapping and systematic field surveys were performed in Dachuan District, Dazhu County in Dazhou City and Xuyong County in Luzhou City from 2014 to 2018. The results showed that the dominant species of rice planthoppers was Sogatella furcifera in eastern Sichuan. According to the data obtained from light trapping, the first occurrence of rice planthoppers in southeast Sichuan (Xuyong County) appeared in early and middle May, but in northeastern Sichuan (Dachuan District and Dazhu County), in late May to early and middle June. The major peak appeared in middle July to early August. The population of rice planthoppers in Dachuan District, Dazhu and Xuyong counties peaked with the densities of 29 946, 15 353 and 35 607 heads per 100 plants in 2018, 2014 and 2018, respectively. The nymphs accounted for the majority of the population, while the adults were the most frequent observed. The population density of adults in Dachuan District, Dazhu and Xuyong counties peaked with 4 583, 5 452 and 16 870 heads per 100 plants, respectively. Overall, the occurrence of rice planthoppers in eastern Sichuan was more serious in 2014 and 2017-2018, and severer in southeastern Sichuan than northeastern Sichuan. This study suggested that, in eastern Sichuan, the number of rice planthoppers differed greatly among the three different regions within each year and from year to year. The major pest was S. furcifera which mainly damaged plants in their adult stages.
