中文摘要： 2004—2005年在西鄂尔多斯地区，选择巢室数＞300的沙漠石蜂Megachile (Chalicodoma) desertorum Morawitz巢区，通过标记巢室和雌蜂，在整个成蜂活动期连续对沙漠石蜂的筑巢习性和行为进行了观测研究。结果显示：该蜂一生一般能建8~12个巢室，优先利用未被破坏的旧巢。利用旧巢的过程为：选址、清理、修整、贮粮、产卵和封闭巢口；构筑新巢的过程为选址、筑巢、贮粮、产卵、封闭巢口、包埋巢室。构筑一个新巢室需采泥40多次，每巢室蜂粮需采集13~21次，每巢室产卵1枚。
英文摘要： The nesting habits and behavior of Megachile (Chalicodoma) desertorum Morawitz were observed for the duration of the adult lifecycle in the West Erdos Region from 2004 to 2005 The results indicate that this species constructs 8 to 12 nests throughout its life, and that it preferentially uses old, undestroyed nests. The process of restoring an old nest includes site selection, site clearing, nest maintenance, storing food, oviposition and sealing the nest entrance. The process of building a new nest included opening the nest, storing food, oviposition, sealing the nest entrance and lining cells. Each new cell required mud to be collected more than 40 times and was provisioned with beebread 13-21 times. One egg was deposited in each cell.
