α Transpiration in arthropods from various habitats measured in dry air at temperatures between 2° and 30°C.
6 If the vapor pressure deficit is expressed in terms of m g / c m
3 instead of mm Hg, all units cancel out except cm/second. The recip
rocal, seconds/cm, is a measure of r, the resistance of the system.
c This is for larvae whose integuments have been abraded by movement through soil. It is not, therefore, a measure of the permeability of the intact cuticle.
d Derived from figures given in terms of percentages of total weight lost, and therefore very approximate.
