Βιολογία, δυναμική πληθυσμού και αντιμετώπιση του Rhagoletis cerasi L. (Master thesis)
The insect Rhagoletis cerasi (L.) (Diptera, Tephritidae) is the most damaging insect for cherrie orchards. The Biology and the population variation has been studied in two study areas with different altitudes. The varieties used in both estates were Lapins, Sunburst and Ferrovia. Four pheromone traps were placed on each farm (one in each variety and one in the untreated) to monitor the flight and fluctuation of the insect population. Plant protection treatments and fertilization in the cherry orchards were exactly the same until the stage of fruit change color of each variety where the interventions were performed in a fully randomized four-repeat pattern with profil (acetamipird) 250 g /1000 liters per hectare, ikarus (Deltamethrin) 500cc per hectare, deltathrin (deltamethrin) 500cc per hectare and combination of the first two in one spray. Estimation of the cherry damage by Rhagoletis cerasi occurred one day prior to the harvest of each variety. From the captures of the pheromone traps and visual observations was revealed that the insect has one generation per year that the adult flight starts 4-6-2016 and ends 9-7-2016. In the highest altitude orchard the populations were smaller in all three varieties. The maximum of arrests was observed at 600m on 10/6/2016 while at 300m on 14-6-2016. The best results in protection of insect attack were given by the combination profile (acetamipird) and ikarus (deltamethrin) in both areas. Infestations were greater in the orchard with the smallest altitude in all single-use insecticides.
