THE ORGANIC CONTROL OF THE OLIVE FLY: THE EFFICIENCY OF TRAPS AND FOOD LURES GENERIC TOPIC: SCIENCE AND TECHNOLOGY OR PRODUCTION The olive fly (Batrocera oleae Gmelin) is the olive production pest with the greatest economic repercussions, particularly when it comes to high quality, organically produced oils. The experiment was carried out in an olive grove located in the central part of the Iberian Peninsula, in an area with a semi-arid climate. Data regarding the population fluxes of the olive fly was collected during the vegetative period, in conjunction with relative climatic factors. The efficiency two types of traps and food lures for Batrocera oleae was studied: one trap is called “Elkofon”, and consists of a 500cc glass jar with a plastic, mushroom-shaped hood that is yellow (chromatic lure) that has a sunken entrance 35 mm in diameter; the other trap is home-made and is called “Olipe”, brainchild of the Los Pedroches Olive Grove (Córdoba), and is made from re-used soft drink bottles, which are perforated with four holes, all 4mm in diameter. The two food lures were: “entomela”, patented liquid food lure formula, and biammonium phosphate. Study results: the olive fly reached blight levels from mid-August, through the end of October, with maximum population numbers reached in October, due to favorable weather conditions. The chromatic efficiency of the “Elkofon” trap stood out. Phosphate proved to be the more efficient the two food lures, with an average of more than five flies captured per day during the course of the study.
