Abstract

The NonParametric Combination (NPC) methodology is proposed to verify the influence of the lure-and-kill method, using Ecotraps (Vioryl SA), on the distribution of Bactrocera oleae (Rossi) (Diptera Tephritidae) infestation in olive groves, and the integration of this method with copper hydroxide sprayings. This approach does not require the verification of any rigid assumption as many parametric methods do. Results of field trials indicate a strict relationship among the efficiency of the lure-and-kill methodon time, dimension of the field, and population density of the olive fly. Moreover, the lure-and-kill method alone seems insufficient to provide an efficient control of the olive fly population in small olive groves. However, when this method is integrated with two copper hydroxide sprayings, the infestation of drupes is maintained below the damage threshold.
