Many species belong to the order Lepidoptera and Orthoptera are responsible for important damage to agriculture, forestry and stored products that suppose a huge economical losses. Because of the disadvantages of chemical pesticides, the development of safer, more economic and selective compounds to control pest insects are required. The olfactory system plays an important role in the reproduction and food search in moths and butterflies, so the disruption of this system could be a good target in integrated pest management (IPM) strategies. In this thesis, different aspects of the olfactory physiology in T. absoluta and G. molesta have been studied. For the first one, the effect of mating status on synthesis and perception of the sexual pheromone in adults of this specie have been evaluated; and the influence of the host plant over oviposition. Secondly, for both species, its have been analysed the olfactory proteins expressed in antennae of males and females through different proteomic techniques, where a differential expression in an important olfactory group of proteins, like the PBPs and OBPs, was observed in both sexes. Moreover, in the present work it has been evaluated the effectiveness of several methyl ketones and trifluoromethyl ketones, which are structurally related to the sex pheromone of these species of pest moth in laboratory and field tests, and eight essential oils (EOs) and three monoterpenoids present in their composition were tested on different stages of their development under laboratory conditions. The results suggest that the compound E3,Z8,Z11-14:MK is a good behavioral antagonist of the pheromone of T. absoluta, and several of these EOs and monoterpehoid could be considered as agents to control these pests in IPM strategies. Furthermore, it is well known that locusts can cause enormous losses in crops of many countries. Dociostaurus maroccanus (Orthoptera: Acrididae) is one of the most abundant locusts of the Iberian Peninsula and it control suppose a high economic costs. In order to develop environmentally-friendly control strategies for this pest, electrophysiological and behavioral studies have been combined to verify that phytal, a specific compound of this specie, as a possible component of the pheromonal complex of the locust. The results obtained point to R,R isomer is an aggregation pheromone because of their attractive effect on adult insects of both sexes.
