...P. C. Croghan; J. Noble-Nesbitt; A. G. Appel ABSTRACT A method is described for investigating the rate of loss of water and carbon dioxide from terrestrial insects by absorbing tritiated water and 14 CO 2 from a gas stream flowing past the insect. The loss of water and carbon dioxide can be studied...

...J. Noble-Nesbitt; A. G. Appel; P. C. Croghan ABSTRACT Tritiated water (THO) loss from Periplaneta americana is used to measure cuticular permeability ( P d ). In dry air, following various periods of predesiccation, the values of P d lie around 0.5×10 −9 m s -1 , with the lowest values below 0.3×10...

... surface areas are estimated from standard equations, in order to express cuticular EWL in units independent of body weight. Loveridge (1980) has suggested that such estimates of surface area may be as much as an order of magnitude too low. We describe here an alternative technique using tritiated water...
