摘要：

Melanization and reddish colouration hormone (MRCH) which regulates colour polymorphism associated with phase variation in the armyworm species has been purified from a head extract of the silkworm, Bombyx mori. Amino acid sequence analysis of MRCH-I established its primary structure and demonstrated that MRCH-I was the same molecule as pheromone biosynthesis activating neuropeptide (PBAN-I) purified from the same extract. Natural and synthetic MRCH-I (PBAN-I) revealed interspecific activity both in cuticular melanization and in sex pheromone production. In the common cutworm, Spodoptera litura, synthetic MRCH-I(PBAN-I) induced cuticular melanization in the larval stage and sex pheromone production in the adult stage. These findings suggest that some lepidopteran insect utilize the same neurohormone, MRCH and PBAN, in different physiological events according to developmental stages and species. © 1990.
