| 为掌握台安丝潜叶蜂Fenusella taianensis Xiao & Zhou在武威地区的发生规律和高效利用粘虫板进行成虫监测诱杀，本研究选定了2个不同海拔的监测点，通过田间挖茧、室内观察和野外调查相结合的方法研究其生活史及种群动态，并比较了不同颜色粘虫板及其不同悬挂方法的诱集效果。结果显示：（1）台安丝潜叶蜂在武威地区一年发生1代，成虫始见于4月上中旬，终于4月底5月初，发生高峰期持续时间短且较为集中，羽化期因海拔高度不同略有差异。（2）9种颜色粘虫板对台安丝潜叶蜂成虫均有诱集效果，以黄绿色粘虫板诱集效果最好，两个监测点的诱集量分别为2 951.33头/板、4 450.33头/板，黄色和绿色粘虫板次之，均在2 000头/板以上，各颜色粘虫板对天敌昆虫的影响均比较小，诱集到的天敌昆虫数量最高仅为10.33头/板。（3）粘虫板以朝南方位诱集到的台安丝潜叶蜂成虫数量最多，两个监测点均在1 500头/板以上，显著高于北、西、东3个方位，朝北方位诱集到的成虫数量最少，在300~400头/板；悬挂高度以距离地面100 cm处诱集到的成虫数量最多，分别为1 273.33头/板、1 591.33头/板，150 cm高度次之，且两者无明显差异，0 cm处诱集到的成虫数量最少；粘虫板在林内的悬挂位置越靠近林缘位置，诱集到的成虫数量越多，其中林缘处最多，分别为1 527.00头/板、1 878.33头/板，距林缘40 m处诱集到的成虫数量最少，均在200头/板以下。该结果对台安丝潜叶蜂成虫绿色防控具有指导意义。 |

| In order to understand the occurrence pattern of Fenusella taianensis Xiao & Zhou in the Wuwei area and to efficiently use sticky traps for adult trapping and monitoring, we selected two fixed monitoring points at different altitudes to research their life history and population dynamics through a combination of field cocoon digging, laboratory observation, and field investigation. The trapping effects of different colored sticky traps and their different hanging methods were compared. The results showed that: (1) F. taianensis occurred one generation per year in the Wuwei area, with adult insects first appeared in early to mid-April and finally reached the end of April or early May. The peak period of occurrence was short and relatively concentrated, and the eclosion period varied slightly due to differences in altitude. Sticky traps of all 9 colors were effective in attracting F. taianensis adults, with the yellow-green traps being the most effective, capturing 2 951.33 and 4 450.33 insects per trap at the two monitoring sites, respectively. The yellow and green sticky traps were the next most effective, both capturing above 2 000 insects per trap. The impact of all colored sticky traps on natural enemies was relatively small, with the highest number of natural enemies attracted being only 10.33 insects per trap. (3) Sticky traps facing south captured the highest number of F. taianensis adults, exceeding 1 500 per trap at both sites, significantly higher than those facing north, west, and east. Traps facing north captured the fewest adults, ranging from 300~400 per trap. Regarding hanging height, the highest number of adult insects were captured at 100 cm above the ground, with 1 273.33 and 1 591.33 per trap, respectively. The second highest number was at the height of 150 cm, and there was no significant difference between the two. Traps placed at 0 cm captured the fewest adults. Regarding placement within the forest, the closer the sticky traps was to the edge of the forest, the more adults of F. taianensis were attracted, with the highest number at the edge of the forest (1 527.00 and 1 878.33 per trap, respectively). The lowest number of adult insects was observed at 40 meters from the edge of the forest, all below 200 per trap. This result has guiding significance for the green prevention and control of F. taianensis adults. |
