中文摘要： 采用人工标记释放回收技术，探讨了杀虫灯诱杀斜纹夜蛾Spodoptera litura Fabricius和甜菜夜蛾Spodoptera exigua Hübner的有效距离及不同安装高度的诱杀效果。诱杀结果表明，标记释放虫源离灯越远，其灯下回收率越低；灯高0.8 m的灯下回收率显著高于灯高1.3 m。提出了用“可控距离CID”、“诱杀中距离MTD50”、“诱杀黄金距离GTD61.8”3个生态学参数量化与规范杀虫灯对昆虫的诱杀距离。拟合结果表明，高0.8 m杀虫灯诱杀斜纹夜蛾和甜菜夜蛾的可控距离分别为115.1 m、110.9 m，诱杀中距离分别为71.8 m、67.4 m，诱杀黄金距离分别为61.5 m、57.1m，可控面积分别是4.2 hm2、3.9 hm2；高1.3 m杀虫灯诱杀斜纹夜蛾和甜菜夜蛾的可控距离分别为108.1 m、107.8 m，诱杀中距离分别为66.6 m、64.7 m，诱杀黄金距离分别为56.7 m、54.5 m，可控面积分别是3.7 hm2、3.6 hm2。

英文摘要： The effective distance for light-trapping Spodoptera litura Fabricius and Spodoptera exigua Hübner, and the relative trapping efficiency of lighttraps at two different heights, were studied using markreleaserecapture methods. The results indicate a lower recovery rate of marked insects at longer distances from light-traps and that the recovery rate for lights hung at 0.8 m was significantly greater than that of lights hung at 1.3 m. Lights hung at 0.8 m trapped significantly more S. litura and S. exigua than those at 1.3 m, but lights at both heights trapped both species equally effectively. Three ecological parameters, the Capable Insect\|killing Distance (CID), the Median Trapping Distance (MTD50) and the Golden Trapping Distance (GTD61.8), are proposed to quantify and standardize the effective distance of lighttraps. The fitted results show that the CID for S. litura Fabricius and S. exigua using 0.8m high lighttraps was 115.1 and 110.9m respectively; the MTD50 was 71.8 m and 67.4 m respectively and the GTD 61.8 was 61.5 m and 57.1 m respectively. The effective trapping area was 4.2 and 3.9 hm2 respectively. The CID for these species using 1.3 m high lighttraps was 108.1m and 107.8m respectively, the MTD50 was 66.6m and 64.7 m respectively and the GTD61.8 was 56.7 m and 54.5 m respectively. The effective trapping area for each species was 3.7 hm2 and 3.6 hm2 respectively.
