Abstract:
Grape moth is key insect pest in Albanian vineyards. Traditionally, some three to four chemical
treatments are carried out with conventional insecticides every year. When matting disruption
method was applied, no more chemical treatments were carried out. The vineyard farmers are not
aware about the significant role that matting disruption plays comparing with conventional
treatments. According to our observations, the isolation distance avoids reaching of fertile grape
moth coming from untreated vineyard to treated ones. The experiment was carried out in Durres
region during 2014-2015. Trials show that in the treated vineyard with disruption pheromones
with 10 m distance from untreated the rate of infestation was 18 %. In treated vineyard with
matting disruption pheromones, where the distance from untreated was 85 meters the infestation
rate was 8,5 %. In treated vineyard with disruption pheromones in 200 meters distance from
untreated vineyard, the infestation rate was 3,5 %, whereas in 1500 meters distance from
untreated vineyard infestation was 2%. In untreated area (neither chemical insecticides nor
disruption pheromones), where the distance was 1000 meters, the infestation rate was 38%.
When the isolation distance was 200 meters among treated vineyards with mating disruption
pheromones from treated with conventional insecticides results with the lowest infestation rate
(3.5%).
