The Coffee Berry Borer, Hypothenemus hampei (Ferrari) is the most destructive pest of coffee worldwide. Available methods for monitoring this insect are limited and they are mainly based on imprecisely, high cost strategies. Despite alcohol traps have been used for this end, the representativeness of results is yet low. It is proposed in this project the development of a new strategy of monitoring and management for this pest, including a new trap model, the addition of new semiochemicals, the establishment of a Threshold Level (TL), and the reduction of captures of non-target insects (parasitoids, predators, and pollinators). The first step will be the selection of the best trap by comparing five different trap models, of which three have never been tested before, which will be compared to the models Iapar (homemade) and Biocontrole Broca (commercialized in Brazil). Next, the range of action of the selected model will be determined by mean of liberation and recapture of the Coffee Berry Borers. Posteriorly, the captures of females of H. hampei will be correlated to the damages on coffee fruits in order to obtain the threshold level. Finally, it will be done the optimization of the attractants by adding new volatile compounds in the lures, including volatiles from coffee flower and coffee fruits. (AU)
