Abstract

Although Brazil is the world's largest producer of sugarcane, with more than 8 million hectares planted, and the sugarcane borer, Diatraea saccharalis, is considered its main pest, the sex pheromone of this insect has not yet been fully elucidated. For this reason, there is no inexpensive and efficient sampling system for large sugarcane areas, which requires labor and time-consuming sampling processes (e.g. for opening and counting caterpillars inside the stems (fixed points per hectare or by the man-hour system). In this sense, to seek a more rational management strategy for this crop pestand to support the expansion of its biological control, which occupies less than half ofthe planted area, this project aims to identify the sexual pheromone of D. saccharalisand make available a commercial formulation for its use in traps.
