Abstract

In the Korça region of Albania, (C.pomonella) is a key insect pest in apple production. Insect develops two complete generations per season. To protect the apple fruits from codling moths, an average of three treatments with conventional insecticides per season are carried out. In the year 2022, the mating disruption method of C. pomonella, was used for the first time using the ISOMATE CTT product with the active ingredient (E, E)-8, 10-dodecadien-1-ol (codlemone.) The field tests were carried out in four apple blocks of the Korça area, with a total of 2.66 ha. The product is formulated in dispenser form. Each dispenser consists of duplicate plastic threads, joined & sealed at the ends. Dispensers have absorbed inside the tubes, the codling moth pheromones. Are used 500 dispensaries/ha off the apple. One dispensary thread protects 20 m2 of orchards. The dispensers were hung in apple trees, at the time, when the monitoring pheromone traps, caught the first C. pomonella adult. An isolation distance of 200 m was respected between the blocks treated and not treated with ISOMATE CTT. In the whole season, only one treatment is carried out. ISOMATE CTT kept the infection at the limit of the tolerated economic damage;3-5 infected fruits in 1000 analyzed fruits. The cost with ISOMATE CTT was 30 % more expensive than with conventional insecticides. Product ISOMATE CTT is registered for apple organic production because it has no negative impact on apple fruits and the environment in general. The study was supported by GiZ.
