网站的摘要特征。12自然熊蜂ruderatus殖民地报告;大多数是地下。该物种（和B.在23-25个砖或浮石混凝土的地面蜂巢中，土蜂（terrestris）占8-32%，在45个具有泥土地板和塑料屋顶的地下蜂巢中，土蜂占93%。高殖民地死亡率，显然是过度冷凝造成的，发生在塑料地下蜂巢，但补救取代塑料屋顶的筑巢腔与部分掩埋浮石混凝土蜂巢。16只中茧量完成B。ruderatus菌落数为418个。本文介绍了一种根据平均大小和工蜂或雄蜂和蜂王茧数计算“生产力指数”的方法。
Abstract Features of the sites of. 12 natural Bombus ruderatus colonies are reported; most were subterranean. This species (and B. terrestris) occupied 8-32% of 23-25 surface hives of bricks or pumice concrete, and 93% of 45 underground hives with earth floors and plastic roofs. High colony mortality, apparently caused by excessive condensation, occurred in plastic underground hives, but was remedied by replacing the plastic-roofed nesting cavities with partly buried pumice-concrete hives. The mean cocoon count In 16 completed B. ruderatus colonies was 418. A method for calculating a ‘productivity index’ based on mean sizes and numbers of worker or male and queen cocoons is described.
