摘　　要：为了掌握稻水象甲在贵州省的种群发生情况,本研究于2011年至2018年连续8年进行稻水象甲种群动态监测,并与当地气候因子结合,进行相关性分析。结果表明:稻水象甲主要在4月到9月上旬之间发生,其成虫每年始见日均在4月份,高峰期出现在4—5月份。灯光诱集稻水象甲单日虫量最高可达4794头,全年灯下有虫日数少,17~32 d不等。全年温度与稻水象甲的诱集量呈正相关,而降雨量与稻水象甲的诱集量呈负相关,相关性较低。贵州平坝稻水象甲不同年月之间灯下种群波动非常大。研究结果可为贵州平坝稻水象甲的预测预报提供参考。The rice water weevil was initially doscovered in Pingba County,Guizhou province in 2010.The population dynamics of the rice water weevil in Guizhou were monitored from 2011 to 2018 to understand ist fluctuations.Correlation analysis was conducted to investigate the influence of climate factors on the population dynamics of the rice water weevil.The results revealed that the rice water weevil mainly occurred between April and early September annually,with its initial emergence in April,and peak occurrence observed from April to May.The maximum capture rate of adults by the light trap was 4794 adults per day.The collection period for rice water weevils using light traps ranged from 17 to 32 days within a year,showing a positive correlation between trap numbers and temperature and a negative correlation with rainfall.The population of rice water weevil exhibited significant fluctuations on both annual and monthly scales.Monitoring the population dynamics of rice water weevil could offer valuable insights for predictive purposes in Guizhou.
