Sexual Pheromones - Modern Ecotechnologies for Ecosystem and Environment Protection

The paper is a synthetic study of the author’s results regarding the possibility and advantages of the practical use of sexual pheromones. Synthetic sexual pheromones have been proved by ecological studies to be an efficient method both for the monitoring and control of pest insects. The efficient practical use of pheromones depends on the knowledge we have about the biology, ecology and behaviour of the target species. We present the concrete results obtained during the study of some species of harmful Lepidoptera Noctuidae in agroecosystems (with special reference to Mamestra brassicae L.), the research activity taking place from 1980 to 2000. The role of chemical mediators in general is suggested as ecotechnologies protecting the ecosystems and the environment.
