Animals lose water through a variety of avenues, including evaporation from the skin surface, fecal water loss, urinary water loss and respiratory water loss. This last pathway, respiratory water loss, can be particularly important in small animals and in dry environments. It has long been realized that insects may be particularly vulnerable to rapid water loss due to their small size and their occurrence in dry environments (e.g. stored grain, desert habitats, saline lakes, etc.) . The PI is examining the rates and pathways of water loss in a very small insect, the fruit fly. The PI's goal is to understand how such water loss occurs and what the relation is to the insect's breathing pattern. Such work may be very helpful in developing new non-toxic insecticides and insect control strategies.

动物通过各种途径损失水，包括从皮肤表面蒸发，粪便水分流失，尿水流失和呼吸道水分流失。 在小动物和干燥环境中，这最后的途径，呼吸道流失，尤其重要。长期以来，人们已经意识到，由于昆虫在干燥的环境中的体积小（例如储存的谷物，沙漠栖息地，盐水湖等），昆虫可能特别容易受到快速水分流失的影响。 PI正在检查很小的昆虫中水分流失的速度和途径，即果蝇。 PI的目标是了解这种水分流失是如何发生的，以及与昆虫呼吸模式的关系。 这种工作可能对开发新的无毒杀虫剂和昆虫控制策略非常有帮助。
