Biosynthetic pathways of the pheromone of the Egyptian armyworm Spodoptera littoralis

摘要: Abstract Most insect pheromones comprise multicomponent blends of geometric or optical isomers, and one major question is how insects produce species-specific ratios components for successful reproductive isolation. Key enzymes suggested to be involved in pheromone biosynthesis are acetyl-coenzyme A carboxylase fatty acyl synthetase, chain-shortening enzymes, desaturases, elongases, reductases, oxidases, alcohol acetyl transferases. The female composition the Egyptian armyworm Spodoptera littoralis (Boisd.) highly dependent on origin strain. In this review, we present a summary different reported compositions moth, including from our recent studies subject, as well biosynthetic routes molecular approaches involved. addition, key role played proposed pathways by number important such chain shortening desaturases transferases, outlined, latest developments inhibition these enzymes.
