9507435 Bradley Small insects have a large surface to volume ratio. Since the loss of body water occurs across the integument, such a ratio leads to severe water loss in insects. A major site of water loss in all animals is the respiratory system. Insects control this loss through the action of valves (spiracles) on their breathing tubes (tracheae). Dr. Bradley will study the action of the spiracles in fruit flies selected for resistance to desiccation. His hypothesis is that the respiratory pattern in these insects will be highly modified to conserve water. This study will be of interest to insect physiologists and ecologists interested in the distribution and survival of insects and in the control of insect pests by disruption of the respiratory and water conservation systems. ***

9507435布拉德利 小昆虫的表面积与体积之比很大。 由于身体水分的损失发生在整个珠被上，这样的比例导致昆虫严重的水分损失。 所有动物失水的主要部位是呼吸系统。 昆虫通过呼吸管（气管）上的气门（气门）来控制这种损失。 布拉德利博士将研究果蝇中气孔的作用，这些果蝇是为了抵抗干燥而选择的。 他的假设是，这些昆虫的呼吸模式将被高度修改，以保存水分。 这项研究将是感兴趣的昆虫生理学家和生态学家感兴趣的分布和生存的昆虫，并在控制害虫的呼吸和水保护系统的中断。 ***
