European Grapevine Moth (EGVM), Lobesia botrana (Den. & Schiff.) (Lepidoptera: Tortricidae) is the key pest of grape in Turkey. The efficacy of Isonet LTT has been tested against L. botranain comparison with registered Isonet L dispensers in Manisa and Canakkale, Turkey. One chemically treated vineyard was used to compare infestation levels for each location. By the emergence of the first EGVM adult, ∼320 Isonet LTT and 650 Isonet L dispensers/ha -including borders- were installed once a year. EGVM adults have been monitored in all plots by pheromone traps from the beginning of the flight until harvest. Infestation rates were compared. We indicated that both Isonet LTT and Isonet L dispensers showed excellent performance against the pest without additional treatment in 2015 and 2016. Average infestation rates of EGVM were below the threshold of 6%. EGVM infestation has been maintained at zero level by sprayings five and four times in the chemical treated vineyard in 2015 and 2016 in Manisa. Isonet LTT dispensers released 340 and 370 mg pheromone until harvest (19 August 2015 and 16 August 2016) in Manisa, whereas they released 360 and 410 mg of until harvest (27 August 2015 and 22 August 2016) in Canakkale, respectively.
