AB [EN] The olive moth (OM), Prays oleae (Bern.) (Lepidoptera: Yponomeutidae), is a major olivegrove pest worldwide; however, until now, very few studies have investigated the effectivenessof mating disruption (MD) techniques against this pest. Experiments were carried out for twosuccessive years (2019 and 2020) in three different olive groves in Andalucía (Southern Spain) toevaluate mating disruption’s efficacy in controlling the OM from the first to the third generation. Theeffectiveness of MD formulations against the three generations of OM was assessed by determiningthe percentage of infested olive fruits, the reduction of pheromone trap catches, and the numberof affected inflorescences in both MD-treated and untreated control olive groves. The number ofrelease points (one or two aerosol devices per ha) was also evaluated. In all years and trials, themean number of males caught in traps placed in the MD-treated plots was significantly lower thanuntreated sites. Mating disruption registered a high suppression of male captures (>75%) in treatedplots for two consecutive seasons. Concerning infested olive fruits, substantial reductions (about80%) were observed in the MD plots of locations B and C, and a reduction of about 40% was detectedin location A, compared to the control plot. Results showed that the installation of two aerosoldevices/ha reduced fruit damage below 20% of infested olive fruits except for one site where areduction of about 71% in the MD plot was recorded in 2019. Although few significant differenceswere associated with OM male catches and infested olive fruits between plots treated with oneaerosol/ha and two aerosols/ha in most of the comparisons, significant differences in the number ofolive inflorescences infested by P. oleae were found, suggesting a similar performance between thetwo tested aerosol densities. Results of two-year field trials in Andalucía demonstrated the potentialof Mister P X841 aerosol devices as an effective tool for controlling the olive moth, P. oleae.
