Abstract:

The studies have been carried out in the 1–3 hectares of the wooden garden, which is located in the Elazığ Central and Elazığ Örençay village, and has been carried out in three different periods, determining the low, medium and high population periods of the damage. In the studies; 1, 2, 3, 4, 7, 10 and 14 days, Cacopsylla pyri L. (Hemiptera: Psyllidae) individuals were counted. As a result of the calculations, which colour of yellow attracted most C. pyri individuals, is determined by the tests of Kruskal Wallis and Mann-Whitney U, whether there is a meaningful difference between the traps. Furthermore; the natural enemies captured in the trap at the end of the 14th day were identified and shown with the help of column graphs in which the color shade more natural enemies were drawn. The study found that the yellow colour with the 1023 hole code attracted the most harmful individuals and the least natural enemies. It is believed that the colour of this colour effectively attracted the C. pyri individuals in the wooden gardens and the results of the studies carried out by producers hanging in different numbers in order to prevent their damage, positive results can be obtained.

Abstract:

The studies were carried out in 2 different 1-3 acres of pear orchards in Elazığ Center and Elazığ Örençay villages the harmful low, medium and high population periods were determined and carried out in 3 different periods. In the studies, Cacopsylla pyri L. (Hemiptera: Psyllidae) individuals caught in traps on 1, 2, 3, 4, 7, 10 and 14 days were counted. As a result of the counts, it was determined by Kruskal Wallis and Mann-Whitney U tests whether there is a significant difference between traps, which color attracts most C. pyri individuals. In addition, at the end of the 14th day, natural enemies caught in the traps were identified and the color graphics helped to determine which color tones attracted more natural enemies. It has been determined that the most harmful individuals of the yellow color tone with a trap code of 1023 are the least natural enemies. It is considered that this color tone effectively attracts C. pyri individuals in the pear orchards and positive results can be obtained as a result of the work to be done by the producers in different numbers in order to prevent their harm.
