摘　　要：为探明辽河三角洲稻田不同管理方式下稻飞虱发生情况,连续2 a进行了稻飞虱发生总量及种群动态趋势调查,结果表明,常规稻田粗放管理方式下,稻飞虱发生总量最高(65.67头/穴),其次为蟹田清洁生产系统,而常规稻田清洁生产方式下,稻飞虱发生总量最低(46.80头/穴);三类稻田稻飞虱种群动态趋势大体一致,2022年与2023年没有显著差异。In order to investigate the population dynamics of rice planthopper under different management methods in Liaohe Delta region,the total occurrence and population dynamics trend of rice planthopper were investigated for two consecutive years.The results showed that the total occurrence of rice planthopper was the highest(65.67 individuals for one rice plant)under conventional extensive management(CE),followed by the clean production system of rice-crab fields(RC).The total occurrence of rice planthopper was the lowest(46.80 individuals for one rice plant)in conventional cleaning management(CP).The population dynamic trend of rice planthopper in the three types of paddy fields was generally the same,and there was no significant difference between 2022 and 2023.
