中文摘要：
为了改进大豆田蓟马监测方法,提高防治效率,通过田间诱集试验研究了3种颜色色板对大豆田蓟马的诱集效果。结果表明：黄色色板的诱集效果较好;蓟马主要在大豆植株上方0.2-0.4 m高度范围活动;南面朝向色板诱集的蓟马数量较多;蓟马日间活跃时段为6∶00-10∶00;色板田间诱集益害比均较低,黄色、绿色、蓝色色板分别为1∶89.4、1∶74.3、1∶62.7。因此,建议用黄、蓝色板监测大豆田蓟马种群动态时,色板设置高度以色板下缘与植株顶部平齐为宜。
英文摘要：
Fields experiments were carried out to evaluate the trapping effects of traps color, trapping heights and orientations on thrips from June to September in 2015. The results showed that the three-day averaged number of three thrips, Thrips tabaci, T. nigropilosus, Frankliniella intonsa, trapped by yellow sticky cards was significantly higher than that by blue and green sticky cards. The number of thrips trapped by sticky cards hung above the plants within the range of 0.2m - 0.4 m was higher than those of other three heights. In addition, the number of thrips trapped by south-facing cards was significantly higher than those in other orientations. The thrips were more active in a time interval of 6：00 - 10：00. The ratio of beneficial insect to pest trapped were 1：89.4, 1：74.3 and 1：62.7 in yellow, blue and green cards respectively. The Yellow and blue sticky cards could be used to monitor and control trips in soybean fields.
