| 中文摘要: |
| 调查了明亮长脚金龟在不同寄主植物上的分布, 结果表明, 肋果沙棘上金龟的数量显著多于金露梅、水柏枝和狼毒。通过利用十字阻隔式诱捕器诱捕金龟的方法调查了明亮长脚金龟对不同颜色的趋性, 结果显示, 明亮长脚金龟对黄色的趋性最强, 显著高于其他颜色, 其他依次为白色、蓝色、紫色、青色、橙色, 对绿色和黑色的趋性较弱。进一步利用黄色诱捕器调查了明亮长脚金龟的日发生规律, 结果显示, 明亮长脚金龟每天活动高峰在12:00-14:00, 此时温度达到26 ℃, 回归分析结果表明金龟的活动规律与温度成正相关。 |
| 英文摘要: |
| Hoplia spectabilis Medvedev (Coleoptera: Scarabaeidae), a long-legged chafer, has caused significant damage and even death to several key species of woody shrubs. In this study, we investigated the distribution of H. spectabilis on different host plants. The number of long-legged beetle on Hippophae neurocarpa was significantly more than that on Potentilla fruticosa, Myricaria germanica, and Stellera chamaejasme. Color traps in the field by using cross-pane funnel (barrier) traps demonstrated that the yellow trap caught significantly more beetles than other color traps, followed by white, blue, purple, cyan, and orange, and the green and black trap caught less beetles. Therefore, yellow traps were used to monitor daily activity rhythm of the beetles. The beetles were active during 10:00 and 18:00 when temperature was above 15 ℃. The peak time was from 12:00 to 14:00 when temperature reached at 26 ℃. Regression analysis between the number of beetles caught by yellow traps and temperature showed that the activity of beetles was positively related to temperature. |
