Abstract

Methyl laurate applied to the surface of house cricket eggs induces a melanization of the extra-embryonic fluid which is due to the oxidation and polymerization of dopamine. Melanization can be delayed or prevented by the addition of 5% vitamin E to the methyl laurate. Methyl laurate appears to activate a phenolase system in the extra-embryonic fluid, and this system or activation of this system is inhibited by vitamin E.
