Abstract

The structure and position of the spiracles in Sitophilus granarius and Tribolium confusum adults was studied. On the basis of this an attempt was made to explain the differences in water loss from these two species under reduced pressure. It was concluded that the spiracular structure combined with the inflation of the body under very low pressures, can account for the apparently anomalous water loss results.
