The agriculture is the base of the Brazilian economy, and both agribusiness and small-scale farmers need new technologies to improve productivity combined with sustainability. In the last 25 years, Embrapa has worked with semiochemicals, mainly insect pheromones and plant volatiles, trying to deploy new tools to control pests on agriculture. In this presentation, we will present the development of six products that Embrapa has developed with a high potential to reach the society. 1) The sex pheromone of brown stink bug Euchistus heros to its control on soybean crops, 2) a new method using semiochemicals from Alphitobius diaperinus to its control in Brazilian poultry houses, 3) a technology combining the aggregation pheromone of Anthonomus grandis with a specific blend of six compounds from cotton plants to manage the boll weevil, 4) the sex pheromone of Tibraca limbativentris for its control on rice crops, 5) sex pheromone Hypsipyla grandella to its control in Cedro crops and 6) the sex pheromone of Spodoptera spp. There is a strong wish that semiochemicals become a common tool to management integrated pest management aiming to have a more sustainable control method. However, from the elucidation of chemical structure to reach the final product, in general, need a series of steps involving laboratory bioassays and field tests and can take several years. We will discuss the main last steps to for each of these four technologies to test them in field experiments and the main difficulties to deliver biotechnological products to the society.
