| 摘 要： | 为掌握竹卵圆蝽在贵州赤水市竹林中的发生规律,在不同立地条件下设置固定样地,进行了连续4年的观察,运用数量化理论I模型分析了温度、降雨量、相对湿度等因子对虫口数量的影响。结果显示,影响虫口数量的因子作用大小排序为:年份立地月份月平均气温月降水量相对湿度。研究结果为建立预测预报模型,和制定有效的预防措施提供了依据。

| Abstract: | In order to understand the occurrence rule ofHippotiscus dorsalis in bamboo forest of Chishui City, Guizhou Province, permanent sample sites were set up in different site conditions and observed for 4 straight years. The quantitive theory （I） model were used to analyze the impact of the worm population quantity on temperature, rainfall, relative moisture, etc. The results showed that the factors to worm population quantity were order by year 〉 site 〉 month 〉 monthly average temperature 〉 monthly rainfall 〉 relative moisture. The study results provided bases for setting up forecast model and developing effective measures to prevent the occurrence of H, dorsalis. |
