研究了成年雌性阿拉伯按蚊和冈比亚按蚊的抗干燥性和水平衡。当这两个物种在相同的条件下从卵饲养到成虫时，An。 arabiensis 的抗干燥能力显着高于 An. arabiensis。冈比亚。数据表明，这种抗干燥性的差异与 An. 干燥前较高的体内含水量有关。阿拉伯。没有观察到干燥过程中失水率或死亡时含水量的差异。代谢率和呼吸模式的测量也显示物种之间没有统计学上的显着差异。这项研究首次对这些物种的成虫的干燥抵抗力进行了生理测量，并提供了对与干燥应激差异抵抗力相关的生理差异的见解。
Desiccation resistance and water balance were studied in the adult female mosquitoes Anopheles arabiensis and Anopheles gambiae sensu stricto. When the two species were reared from egg to adult under identical conditions, An. arabiensis had significantly higher desiccation resistance than did An. gambiae. Data are presented that indicate that this difference in desiccation resistance is associated with a higher body water content prior to desiccation in An. arabiensis. No differences in rate of water loss during desiccation or water content at death were observed. Measurements of metabolic rate and respiratory pattern also showed no statistically significant differences between the species. This study provides the first physiologic measurements of desiccation resistance in adults of these species and offers insights into the physiologic differences associated with differential resistance to desiccation stress.
