Diyarbakır, Elazığ ve Mardin illeri badem ağaçlarında zararlı Agrilus roscidus Kiesenwetter, 1857 (Coleoptera: Buprestidae)'un ergin popülasyon değişiminin belirlenmesi

Abstract

This study was carried out to determine population fluctuations of the pest, Agrilus roscidus Kiesenwetter, 1857 in almond orchards of Diyarbakir, Mardin and Elazig provinces in South-east and Eastern Anatolia regions between 2002 and 2004. The population fluctuation of the Agrilus roscidus (Coleoptera: Buprestidae) was monitored by weekly sampling from the beginning of March until the end of November with the fall of leaves. The sampling method was based on the techniques usually applied in orchards, namely knocking the adults out of the trees by the frappage (beating) method. Twenty-five trees at about the same stage of growth were randomly selected in each biotope and four branches per tree (4 X 25= 100 branches) were sampled. These branches were given three blunt beatings with a stick wrapped in foam rubber and the adults that fell onto a piece of cloth, 50 X 50 cm were collected. Results of the study suggested that population densities of the pest were higher than those in Diyarbakir and Mardin throughout of the study. The highest density of the pest was recorded of Akbag location in Mardin province. Population density of the pest was low in Elazig. Occurrence of the pest generally observed between March and August in the all of province.
