摘　　要：为了解苜蓿(Medicago spp.)蓟马群落消长规律,于2019年4月下旬−9月下旬使用2种颜色(蓝色和黄色)诱虫板,分别悬挂在不同高度和朝向,对苜蓿田内的苜蓿蓟马群落进行诱集和发生动态监测。结果表明:8月上旬是苜蓿蓟马为害最为严重的时期,7月中旬−8月上旬是优势种牛角花齿蓟马(Odontothrips loti)的发生高峰期。两种诱虫板对苜蓿蓟马群落和牛角花齿蓟马的诱集量在苜蓿刈割第3茬时显著高于其他3茬(P<0.05)。其中,蓝色诱虫板对苜蓿蓟马群落的诱杀效果较好,优势种牛角花齿蓟马对黄色诱虫板的趋性较强。诱虫板的悬挂高度在苜蓿植株顶端时诱杀效果最好;板面朝东、南两个朝向诱集到的苜蓿蓟马数量多于其他朝向。此外,多因素方差分析表明诱虫板颜色、悬挂朝向和悬挂高度均对苜蓿蓟马诱虫效果有极显著影响(P<0.01)。To understand the population dynamics of thrips on alfalfa,blue and yellow sticky traps were used in a clover field from late April to late September,2019.We also utilized different directions(east,south,west,and north)and different hanging heights(mid of alfalfa,top of alfalfa,and 20 cm above the top of alfalfa).Most of the thrips on the alfalfa were collected by both colored sticky traps in early August.The population of Odontothrips loti reached its highest peak in mid-July to early-August.The largest amount of thrips on the alfalfa and O.loti were collected during the third harvest,which showed a significant difference to the other three harvests(P<0.05).The results showed that the thrips on the alfalfa preferred the blue sticky traps,whereas O.loti had a strong tendency for the yellow sticky traps.The hanging height at the top of the alfalfa was suggested for the sticky cards.In addition,the number of thrips trapped in the east and south was greater than the other two directions.Multi-way analysis of variance showed that the trapped number of thrips was significantly influenced by color,direction,and height(P<0.01).
