Abstract

Neutron activation analysis was used to measure phosphorus in individual beetle wings during pupal and early adult stages. By counting neutroninduced P32 radioactivity it was possible to measure 0.005 ± 0.001, µg of phosphorus. The phosphorus content of the wings rises to maximum at eclosion and subsequently decreases with loss of cells.
