摘  要：
本文采用灯光诱捕和田间系统调查相结合的方法,调查和分析了2009-2013年贵州道真县褐飞虱种群发生动态。结果表明:不同年份间灯下褐飞虱始见日和高峰频次波动较大,2011年单日最大诱虫量达11 243头,分别是2009年、2010年和2013年的32倍、21倍和10倍;2012年单日最大诱虫量仅为90头。2010、2011年早栽稻田褐飞虱发生量与晚栽田的基本持平,而发生高峰日迟于早栽田;早栽田长翅、短翅成虫发生量均低于晚栽田,2010年褐飞虱发生高峰日集中在7月上中旬和8月中旬,发生量小于500头/百丛,2011年褐飞虱发生高峰日集中在7月中旬和8月下旬,发生量小于1 000头/百丛。结果表明褐飞虱在道真县可发生不完全6代;2010、2011年道真县褐飞虱为轻发生(Ⅰ级)或偏轻发生(Ⅱ级)。

摘  要：
In order to provide a theoretical basis for integrated control of the brown planthopper,Nilaparvata lugens(Stl)in Daozhen County,population dynamics of N.lugens were systematically investigated by using light traps and systematic field surveys from2009 to 2013 in Daozhen County,Guizhou Province.The results revealed that the first occurrence date and frequency of occurrence peak of N.lugens was volatile among five years.The maximal daily catches of N.lugens amounted to 11 243 in 2011,which were 32 times,21 times and 10 times as much as those in2009,2010 and2013,respectively,while only reached90in2012.The occurrence amount of N.lugens was nearly same in different fields in 2010 and 2011.The occurrence peaks in the late transplanting fields were later than those in the early one.The occurrence degree of macropterous N.lugens and brachypterous N.lugens in the early transplanting fields was inferior to that in the late one.The occurrence peak of N.lugens was mainly in early or middle July and middle August in 2010,the occurrence amount of N.lugens was less than 500 heads per 100 hills.The occurrence peak of N.lugens was mainly in middle July and late August in2011,the occurrence amount of N.lugens was less than 1 000 heads per 100 hills.These results indicate that incomplete six generations of N.lugens could occur per year in Daozhen,and the occurrence of N.lugens wasⅠ class orⅡclass in 2010 and 2011 in Daozhen.
