【摘要】 为比较黑光灯与性诱剂对水稻二化螟诱捕效果的差异,于2019—2020年在益阳地区开展了相关试验,并就气象因子与诱捕效果的相关性进行了研究。结果表明:2种诱捕方式捕获的二化螟总体趋势基本一致,各代成虫高峰期及蛾峰日较为接近,相同时间内灯诱蛾量明显多于性诱蛾量;灯下二化螟发生趋势较为真实的反映田间发生情况,性诱捕器对不同世代二化螟的诱捕效果存在差异,越冬代螟蛾对性诱剂最为敏感;2种方法捕获的虫量与同期气象因素具有一定的相关性,越冬代诱捕虫量与气温显著相关。更多还原

【Abstract】 In order to compare the trapping effects of black light lamp and sex attractant on rice stemborer,relevant experiments were carried out in Yiyang area from 2019 to 2020,and the correlation between meteorological factors and trapping effect was studied.The results showed that the overall trends of the two trapping methods were basically the same,the peak period of adults and peak date of trapped moths of each generation were close,and the number of light-trapped moths was significantly higher than that of sexual-trapped moths at the same time;the occurrence trend of rice stemborer under light trapping can truly reflect the occurrence situation in the field;the trapping effects of sexual attractants on different generations of rice stemborer were different,and the overwintering generation of rice stem borer was the most sensitive to sexual attractants;the number of insects captured by the two methods had a certain correlation with the meteorological factors in the same period,and the number of insects trapped in the overwintering generation was significantly correlated with the temperature.更多还原
