为明确榕管蓟马Gynairothrips uzeli Zimmerman最嗜颜色及粘虫色板田间诱集效果,以垂叶榕种植基地为试验点,比较榕管蓟马对10种颜色的嗜好差异,测定粘虫板颜色与悬挂高度、颜色与悬挂密度对榕管蓟马的互作效应,查验3种偏嗜颜色-悬挂高度-悬挂密度组合粘虫板的田间诱集效果。结果表明:榕管蓟马最嗜颜色为黄色,其次为紫色和青色,对其他7种颜色的嗜好较弱;粘虫板颜色、悬挂高度和悬挂密度均极显著影响榕管蓟马诱集,颜色与悬挂高度、颜色与悬挂密度对榕管蓟马诱集存在显著的互作效应;黄、青、紫等3种偏嗜颜色粘虫板的悬挂高度均以色板底端高出垂叶榕顶部10 cm为佳,适宜悬挂密度则分别为4片/100 m2、5片/100 m2和5片/100 m2;3种偏嗜颜色-悬挂高度-悬挂密度组合中,黄色组合粘虫色板对榕管蓟马的田间诱集效果最好。
In order to clarify the most attractive color of Gynairothrips uzeli Zimmerman and the color trap in the field of Mythimna separata and to investigate the effects of different colors on the color of Mythimna separata Thunn. Effect of Suspension Height, Color and Suspension Density on the Interaction of Thompson, Thrips tabaci Thunb. The results showed that the color of Thrips tabaci was the most yellow, followed by purple and cyan, the other 7 kinds of color preference was weaker; the color, hanging height and hanging density of the sticky insect board all had a very significant effect on the induction of the thorn, There was a significant interaction effect between color and hanging height, color and hanging density on the induction of Thrips palmaris; the hanging height of the three preference color sticky panels of yellow, green and purple were higher than the hanging height Top 10 cm is better, suitable for hanging density were 4/100 m2, 5/100 m2 and 5/100 m2; 3 kinds of preference for color - hanging height - hanging density combination, the yellow combination of insect color swatches The best of the field of the thrush Thompson trap effect.
