摘　　要：为探究诱虫板对紫花苜蓿田(Medicago sativa L.)中牧草盲蝽(Lygus pratensis Linnaeus)的诱集作用,本研究分别于2021和2022年,在生长期苜蓿田设置8种不同颜色诱虫板、20 cm和50 cm两个不同悬挂高度、田间边缘和中央两个不同挂板地段和每日早上(7:00—11:00)、中午(11:00—15:00)、下午(15:00—19:00)及晚上(19:00—次日7:00)4个不同挂板时段,调查不同诱虫板及悬挂方式对牧草盲蝽的诱集效果。结果表明两年中牧草盲蝽均对绿色诱虫板趋性最强,试验期间每5 d的平均诱集量分别为9.41头·板^(-1)和10.79头·板^(-1),显著高于其他7种色板(P<0.05);绿色诱虫板悬挂高度在50 cm处诱集效果显著高于20 cm处(P<0.05);在田间边缘地段较中央地段诱虫板的诱集效果好(P<0.05);在每日监测的4个时段内,下午时段诱集到的虫量最多;5月下旬和6月下旬牧草盲蝽为害达到高峰,第二茬苜蓿及前两茬苜蓿现蕾期诱集到的牧草盲蝽数量最多。The aim of the study was to clarify the trapping effects of the sticky trap on Lygus pratens s in alfalfa field.Here,eight different color sticky boards,two different hanging heights of 20 cm and 50 cm,two different hanging locations of the edge and the central of alfalfa field,and four different hanging times in the morning(7:00-11:00),noon(11:00-15:00),afternoon(15:00-19:00)and evening(19:00-7:00 next day)were set in the growing alfalfa field in 2021 and 2022,respectively,to investigate the attracting effects of different color sticky boards and hanging methods on collecting number of the tarnished L.pratensis in alfalfa field.The results showed that the green sticky board had the best trapping effect towards L.pratensis,the average trapping number were 9.41 and 10.79 individuals per board in 2021 and 2022 respectively,significantly higher than those from the other seven color boards.The trapping effect of green board hanged at the 50 cm height was significantly higher than that at the 20 cm(P<0.05).The trapping effect was better when the sticky traps were set at the margin of the alfalfa field than that in the central section(P<0.05).The number of L.pratensis individuals trapped at afternoon was more than those at other times within the same one trapping day.In the year,it was found out that the damage of L.pratensis appeared to its peak in late May and late June;the most L.pratensis attracted in the second crop of alfalfa;and the number of L.pratensis population were the highest in the budding stage of the first and second crop.
