Investigation of shooting efficiency of yellow sticky traps in different wavelengths against pear psyllid [Cacopyslla pyri L. (Hemiptera: Psyllidae)]

Pear is in second place after apple in terms of the production amount in soft-core fruit grown in our country. In terms of our country, pear production as an important export product and a source of livelihood for many families has increased gradually over the years and by the end of 2017 has exceeded 500 thousand tons. The most important problem of pear which is important for our country in terms of our economy is Cacopyslla pyri (L.) (Hemiptera: Psyllidae) which is the most important pest of this fruit. The intensive spraying of pear orchards, especially with broad spectrum drugs, causes the damage to develop resistance to these drugs and the destruction of natural enemies. Moreover, it is even more difficult to solve the problem that the climate conditions in the country are suitable for the development of C. pyri. For these reasons,the use of yellow sticky traps against the pear psyllid C. pyri is an alternative method of management. In this study, which are biotechnical management methodsyellow stickytraps, were used to reduce the activity of C. pyri causing damage to pear orchards. The studies were carried out in 2 different 1-3 acres of pear orchards in Elazığ Center and Elazığ Örençay villagesthe harmful low, medium and high population periods were determined and carried out in 3 different periods. In the studies, C. pyri 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.
