在这篇综述中，我们描述了血液喂养节肢动物的水平衡的要求，特别是对比脱水耐受性在不喂，关闭主机状态和挑战，伴随着接收的血粉过量的水。在脱宿主阶段，大多数基本的水分平衡特征也适用于其他陆生节肢动物。一套协调良好的反应，使节肢动物，以保护水资源，提高他们的干燥耐受性，并增加他们的水供应，采用不同的分子，结构和行为的反应。在非宿主阶段的水分流失率是特别有用的生成一个计划来分类矢量根据其栖息地的水的要求，从而提供了一个方便的工具，具有潜在的预测能力，用于确定合适的当前和未来的矢量栖息地。血液喂养带来了一系列完全不同的挑战，因为载体通过快速增加其表皮水分流失速率和提高利尿速率以排出多余的水分并浓缩血粉来应对水分过多。以血液为食的未成熟阶段通常在血液喂养周期结束时含水量净增加，但在成年人中，当周期完成时，含水量恢复到喂养前的水平。共同的主题是显而易见的，在不同的节肢动物的血液喂养，特别是用于响应水的突然涌入的生理机制，以及用于对抗缺水的机制，在非喂养，关闭主机的状态。
In this review, we describe water balance requirements of blood-feeding arthropods, particularly contrasting dehydration tolerance during the unfed, off-host state and the challenges of excess water that accompany receipt of the bloodmeal. Most basic water balance characteristics during the off-host stage are applicable to other terrestrial arthropods, as well. A well-coordinated suite of responses enable arthropods to conserve water resources, enhance their desiccation tolerance, and increase their water supplies by employing a diverse array of molecular, structural and behavioral responses. Water loss rates during the off-host phase are particularly useful for generating a scheme to classify vectors according to their habitat requirements for water, thus providing a convenient tool with potential predictive power for defining suitable current and future vector habitats. Blood feeding elicits an entirely different set of challenges as the vector responds to overhydration by quickly increasing its rate of cuticular water loss and elevating the rate of diuresis to void excess water and condense the bloodmeal. Immature stages that feed on blood normally have a net increase in water content at the end of a blood-feeding cycle, but in adults the water content reverts to the prefeeding level when the cycle is completed. Common themes are evident in diverse arthropods that feed on blood, particularly the physiological mechanisms used to respond to the sudden influx of water as well as the mechanisms used to counter water shortfalls that are encountered during the nonfeeding, off-host state.
