| 为明确普通大蓟马Megalurothrips usitatus对不同颜色的趋性及其种群在海南豇豆种植高峰期日活动规律与环境因子的关系。本文在海南豇豆盛花期选择8种颜色的粘虫板和自制的64种色卡, 在田间系统性开展普通大蓟马的趋色定量研究, 并评估了粘虫板悬挂的方位、高度和规格对普通大蓟马的诱集效果。在此基础上, 悬挂诱集效果最好的色板, 探究海南冬季普通大蓟马的日活动规律与环境因子之间的关联。研究结果表明，粉色粘虫板和60号色卡(RGB值为255, 160, 255)对普通大蓟马的引诱效果最好, 粘虫板朝向与豇豆植株保持平行, 悬挂高度在140 cm, 色板规格10 cm×10 cm引诱效果最佳。运用色板最优组合开展普通大蓟马的日活动规律调查, 发现普通大蓟马在海南三亚冬季的日活动规律呈单峰型, 活动峰值时间在10:00-12:00。环境因子关联分析发现, 普通大蓟马活动的最适环境温度在28~33℃、相对湿度在51.3%~80.5%、光照强度在23 885~122 284 lx。研究结果揭示了普通大蓟马的颜色趋性和在南方豇豆主产区的日活动规律特性, 为普通大蓟马的物理防控措施的开发和应用奠定了基础。 |
| 英文摘要: |
| Megalurothrips usitatus is a key pest in cowpea production in southern China. To determine its color preference and investigate the relationship between its diurnal activity patterns and environmental factors during the peak cowpea flowering stage, field experiments were conducted in Hainan using eight colors of sticky traps and 64 custom-made color cards. The influence of trap orientation, hanging height, and trap size on the attractiveness to M.usitatus was also evaluated. The results showed that pink sticky trap and color swatch no. 60 (RGB: 255, 160, 255) had the highest attractiveness. Optimal trapping efficacy was achieved when traps were positioned parallel to cowpea plants at a height of 140 cm and in a 10 cm×10 cm size. Diurnal activity monitoring using the most attractive color trap revealed a unimodal activity pattern during the winter in Sanya, Hainan, with peak activity occurring between 10:00 and 12:00. Environmental correlation analysis indicated that M.usitatus activity was optimal at temperatures between 28℃ and 33℃, relative humidity levels of 51.3% to 80.5%, and light intensity ranging from 23 885 to 122 284 lx. These findings provide insights into the pest’s behavioral ecology and establish a foundation for the development and implementation of targeted physical control strategies in major cowpea-producing areas of southern China. |
