The Effects of Traps Hanged on Different Apple Varieties on the Capture of Tropinota hirta (Poda, 1761) (Coleoptera: Cetoniidae)

Abstract

The aim of this study was to capture the Tropinota hirta, fed in the flowers of the Red Chief, Williams Pride and Braeburn apple varieties with traps in Isparta province in 2017-2018, and to compare the damage rate and effect of varieties on trapped and untrapped trees. In the study, the experiments were carried out with five replications. In the study, light blue colored funnel traps with water and attractant (E) -cinnamyl alcohol and [(E) -anethol 1:1 ratio were used. As a result, for all varieties in both 2017 and 2018, it was determined that the number of flowers in the control trees was more than in the trapped ones. The reason for this is that the insects are attracted to the traps by the colors, water, and attractors on trees, and caused more damage to the flowers of trapped trees. These results show that traps can be hung farther from the trees, making catching adults more convenient. In the year of 2017, Williams Pride variety had the highest number of flowers, followed by Braeburn and the lowest number of flowers compared to others were obtained on Red Chief. Similar results were obtained in varieties where the trap was not hung and only the flowers were counted. In 2018, the ranking of the most flowers was changed by the Red Chief, and then by Braeburn, and by least by Williams Pride. This is thought to be due to the differentiation of the flower buds of that year or the climate conditions of the previous year.
