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.

动物通过多种途径失水，包括皮肤表面蒸发、粪便失水、尿液失水和呼吸失水。最后一种途径，即呼吸失水，在小动物和干燥环境中尤为重要。人们早就认识到，由于昆虫体型小，而且多生活在干燥环境中（如储藏谷物、沙漠栖息地、盐湖等），它们可能特别容易遭受快速失水。PI正在研究一种非常小的昆虫——果蝇体内水分流失的速率和途径。PI的目标是了解这种水分流失是如何发生的，以及这与昆虫的呼吸模式有什么关系。这些工作可能对开发新的无毒杀虫剂和昆虫防治策略有很大的帮助。
