摘　　要：2011年在黑龙江省五常市试验研究二化螟性诱盆布放密度。结果表明,每公顷诱盆45、45、30只诱杀盆的处理区6次调查平均每盆累计诱蛾量分别为76.40、68.00、76.80头,在诱盆密度增加50%时,单位面积诱蛾总数则上升49.22%和32.81%。每公顷45、45、30、0只诱杀盆的白穗和半枯穗数分别为0.67、1.50、2.00、7.33个,3个诱杀区防治效果分别为90.91%、79.55%、72.73%。随着诱杀盆密度的增加,防治效果有所上升。作者认为,目前在东北大部分稻区,性诱盆密度以每公顷45盆为宜;对于虫口密度较低地区,诱盆密度可适当降低。Experiment on pheromone trap density for mass-trapping of the rice stem borer,Chilo suppressalis（Walker） was conducted in Wuchang of Heilongjiang Province in 2011.The results showed that the mean numbers of male moth captured per tray in treatments with 45,45,and 30 trays per hectare were 76.50,68.00 and 76.80,respectively.The total numbers of male moths captured increased by 49.22% and 32.81% when trap density increased by 50%.The numbers of white head and semi dry spike were 0.67,1.50,2.00,7.33 in the treatments with 45,45,30,0 trays per ha.The control efficiency was 90.91%,79.55 and 72.73%,respectively,and it slightly increased as trap density increased.The authors believe that the density of 45 traps/ha is suitable for most areas in Northeast China at present,and the density should be reduced to some extent where the pest population density is low.
