| 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。

| Abstract: | Holotrichia oblita (Faldermann) is one of the most destructive agricultural pests in China. In order to reveal the annual occurrence dynamics of and analyze the effects of environmental factors on emergence of overwintering adults, a continuous survey was carried out from 2010 to 2013. The results showed that the peak emergence period still appeared in May from 2010 to 2013, which was approximately consistent with the previous data except for slightly later and longer emergence. However, the preliminary emergence period of 2013 happened later than other years due to the delayed first spring rain, which indicated that the preliminary emergence period of H. oblita adults was influenced by soil moisture. Grey relational analysis showed the average humidity became the critical environmental factor on the emerged adults amount at the peak emergence period, especially temperature and rainfall. Our study would lay a firm foundation for the forecast and control of H. oblita. |
