| 摘 要： | 对金毛弓背蚁Camponotus tonkinus Santschi的巢穴结构、工蚁头宽频数特征及巢外活动节律作了系统的观察和分析。发现金毛弓背蚁地下巢穴极为复杂，有纵横交错的通道系统和众多的小室，蚁后室位于巢穴底部，工蚁的头宽为连续性，范围在1.05-3.85mm，频数分布为不对称的单峰，头宽在1.4～2.Omm的个体最多，占总数的72.7%，晴朗天气里工蚁出入巢活动在上午和下午各有一个高峰，中午随温度升高金毛弓背蚁外出活动进入低谷.

| Abstract: | The present article deals with the nest architecture, frequency distribution of head width and daily rhythm of out-and-in activities of the carpenter ant Camponotus tonkinus Santschi. It is found that this species constructs a very complicated ground nestconsisting of many passages and chambers. The queen chamber is usually located undermost in the nest. The head widths of workers range from 1.05 to 3.85 mm, and its frequency distribution is asymmetric monomodal with a peak at 1.4-2.0 mm (accounts for 72.7% of the total workers). In a sunny day, a typical daily cycle is bimodal, commence foraging in early morning, decline in midday and rise again in late aftemoon through dusk. |
