For the wax-making bees to secrete wax, the ambient temperature in the hive must be 33 to 36 °C (91 to 97 °F).
Epicuticular wax can now also be isolated by mechanical methods that distinguish the epicuticular wax outside the plant cuticle from the cuticular wax embedded in the cuticle polymer. [6] As a consequence, these two are now known to be chemically distinct, [ 7 ] although the mechanism that segregates the molecular species into the two layers is ...
