Abstract
SINCE the work of Pryor1 in 1940, a number of papers have been published on the process of hardening and darkening of insect cuticle after moulting and pupation. According to Pryor, hardening of the insect cuticle is due to the tanning action of an agent produced by oxidation of a phenolic substance. Thereafter, phenols such as protocatechuic acid (3,4-dihydroxy benzoic acid), 3,4-dihydroxyphenyl acetic acid, 3,4-dihydroxyphenyl lactic acid and others have been isolated from various insect cuticles2.
