chinois. 摘 要：香蕉花蓟马[Thrips hawaiiensis（Morgan）]在香蕉园中普遍发生，对香蕉生产造成危害。为了比较香蕉花蓟马对不同颜色的反应、指导田间色板诱虫，本文采用10种不同颜色的黏虫卡研究香蕉花蓟马成虫对颜色的趋性及田间诱虫效果。结果表明，黄色对香蕉花蓟马成虫引诱效果最强，显著高于其他颜色；浅蓝色、白色和粉红色对香蕉花蓟马的引诱效果显著高于剩余6种颜色。黄色黏板的诱虫量变化与香蕉花蓟马田间自然种群数量变化一致，两者相关系数为0．98。色板悬挂高度对香蕉花蓟马的诱集效果有显著影响，色板悬挂高于花蕾时的诱虫数量显著少于色板悬挂于花蕾中部和顶部时的数量。

In order to compare responses of T. hawaiiensis to different colors and guide trapping application in fields, 10 sticky cards of different colors were used to study the taxis of the adults of T. hawaiiensis and the field trapping effects. The results showed that the most attractive color to T. hawaiiensis was yellow. The trapping effects of light blue, white and pink were much more remarkable than those of the other 6 colors. The quantity trapped by yellow sticky cards varied with the field populations, with a correlation coefficient of 0. 98. The hanging height of sticky cards had significant influences on the trapping effect. When the sticky cards were hanged higher than buds, the trapping quantity was few. However, the trapping quantity increased significantly when the sticky cards were hanged at the middle or top of buds.
