Linzer biol. Beitr. 47/1 963-968 31.7.2015 Thrips (Thysanoptera) species occurring in cherry orchards in Isparta province of western Turkey Asiye UZUN, Serdar TEZCAN & Ozan DEMIRÖZER A b s t r a c t : This study was carried out to determine the species of Thysanoptera existing at important cherry orchards in Isparta province of western Turkey during the month of April-June of 2013. At the end of this study, nineteen species belonging to three families of Thysanoptera were determined. The most abundant species in this study were Taeniothrips inconsequens (UZEL 1895), Thrips meridionalis (PRIESNER 1926), T. tabaci (LINDEMAN 1889), Haplothrips reuteri (AMYOT & SERVILLE 1843) and Frankliniella occidentalis (PERGANDE 1895). K e y w o r d s : Thysanoptera, Cherry, Prunus avium, Isparta, Turkey. Introduction Cherry is a fruit which has an important place in the Turkish economy. There are 17.922.171 cherry trees in Turkey and annual production is 494.325 tons (ANONYMOUS 2013). Cherries are widely grown in the Mediterranean, Marmara and Aegean regions of Turkey. 6.42 % of the Turkish cherry production is realized in Isparta, Mediterranean region of Turkey (ANONYMOUS 2013). In the field of cherry production of Turkey, it is seen that there is no detailed information about the species related to Thysanoptera. LODOS (1993) and ULUSOY et al. (1999) re- ported Taeniothrips inconsequens (UZEL) from cherry orchards, ÖZBEK ET AL. (1996) recorded Haplothrips reuteri (KARNY) and Thrips meridionalis. The most comprehensive study on this area was conducted by ŞAHIN & TEZCAN (2014) in 2010 and 2011 and 21 species belonging to Thysanoptera was determined in cherry orchards from Kemalpaşa (Izmir) province of western Turkey. In this study Thrips tabaci (LINDEMAN 1889), T. major UZEL 1895, T. inconsequens (UZEL 1895) and T. angusticeps UZEL 1895 were reported as the most common species. No other study was found which went as far down as the species belonging to Thysanoptera in Turkey. For the purpose of overcoming this absence, conducting a study in the cherry orchards in Isparta which is the most prominent cherry producing area of Mediterranean region of Turkey was deemed necessary. The scope of the study was to determine thrips species during the flowering and fruiting period. © Biologiezentrum Linz, download www.zobodat.at
