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。
In 2011 in Heilongjiang Province, Wuchang City pilot study of the Stem borer induced sexually placed pot density. The results showed that the average number of trapped moths per pot was 76.40,68.00 and 76.80 respectively in 6 treatments of 45,45 and 30 trapping pots per hectare. When the mowing density was increased by 50% The total increased by 49.22% and 32.81%. The number of white spikes and semi-rhizomes per hectare of 45,45,30 and 0 were 0.67,1.50,2.00 and 7.33, respectively. The control effects of the three trapping areas were 90.91%, 79.55% and 72.73% respectively. With the increase of trap pot density, the control effect has increased. The author believes that most of the northeastern part of the current rice, sexually-oriented pot density of 45 pots per hectare is appropriate; for the population density of low larvae, pot density can be appropriately reduced.
