Abstract:

Semiochemicals in scarabs include sex pheromones, aggregation pheromones and attractants of plant origin. Now most of the sex pheromones identified are related to Rutelidae and Melolonthidae, only a few of aggregation pheromones were identified in Dynastidae. Studies on attractants of plant origin are related to Rutelidae and Cetoniidae. This paper summarized chemical structure characters of semiochemicals in scarabs, and reviewed the unique reciprocal role of chiral sex pheromones as agonist antagonist in chemical communication in scarabs and biosynthesis of sex pheromone.

Key words: Scarab beetles, semiochemical, chiral discrimination, biosynthesis, attractant
