不同黄板和二混合色板对烟蚜的引诱作用

The attractiveness of different yellow sticky cards and bi-colored sticky cards to the green peach aphid,Myzus persicae

【目的】探究黄色及其配色对烟蚜Myzuspersicae行为的影响,有助于烟蚜绿色防控技术的优化。为田间黄板诱蚜的应用技术研发提供理论指导。【方法】利用电脑软件设置8种不同RGB黄色以及不同颜色的双色图卡,测定烟蚜对色板的趋性反应。【结果】RGB数值为215∶255∶6的3号黄色对烟蚜的引诱作用显著高于其他黄色,其对烟蚜的平均引诱量为8.5头/块。在3号黄色的基础上配置另一种颜色,发现在面积比2∶1的比例下,相对于3号色板只有3-黑色板降低了诱虫量。在1∶1的比例下,3号黄色比所有双色板对烟蚜的引诱作用都强,说明增加配色的比例会降低黄板的引诱力。在1∶1的比例下不同双色板的引诱力也存在着显著差异,双色之间存在着互作现象,这表明不同配色会影响色板对蚜虫的引诱作用。【结论】3号黄色色板对烟蚜的引诱效果最好。

[Objectives] To test the attractiveness of different colored sticky cards to the green peach aphid, Myzus persicaein order to optimize environmentally-friendly control techniques for this pest. [Methods] The attractiveness of eight different yellow cards, and bi-colored cards, to M. persicae was tested in the lab with the RGB color designed by the Photoshop software. [Results] The No. 3 yellow card with an RGB value of 215 : 255 : 6 was the most attractive, attracting 8.50 individual/card. The color of this card was then combined with other colors to make bi-colored cards. At an area ratio of 2 : 1 of No. 3 yellow to other colors, only the No. 3/black card attracted less aphids than the No. 3 yellow card. At an area ratio of 1 : 1, the No. yellow 3 card was more attractive to aphids than all bi-colored cards, indicating that increasing the area other colors decreased the attractiveness of bi-colored cards. Significant differences were observed among bi-colored cards indicating that different color patterns affect the attractiveness of bi-colored cards to aphids. These results provide a foundation for optimizing the use of yellow sticky card to capture aphids in the field. [Conclusion] The No. 3 yellow sticky card is the most attractive to aphids.
