Pheromones are compounds emitted by insects and vertebrates that specifically modulate the behaviour of the same species. Based on the role, pheromones are classified into different types such as releaser pheromones, primer pheromones, sex pheromones, aggregation pheromones, alarm pheromones and trail pheromones. Insect pheromones are volatile substances consisting mostly of alcohols, aldehydes, ketones, aromatic compounds and isoprenoids. Pheromone biosynthesis comprises fatty acid and isoprenoid metabolic pathways. Pheromone biosynthesis must be precisely regulated since the pheromone blend consists of a mixture of compounds with defined ratios and chemical structures. The main aim of this thesis is to summarize the published information about insect pheromone biosynthesis and regulation with a focus on pheromones involved in sexual communication. Attention will also be paid to the biotechnological potential of pheromones in targeted pest management with the utilisation of enzymes present in the biosynthesis of pheromones. |
