Výskyt potenciálních škůdců sadů, obaleče slivoňového, Cydia lobarzewskii a obaleče trnkového, C. janthinana (Lepidoptera: Tortricidae) v České republice a poznámky k dalším druhům podle úlovků do feromonových lapáků

Abstrakt: The occurrence of three potential orchard pests in the Czech Republic was monitored by means of pheromone traps. Lures based on two different blends of (Z)-8-Dodecen- l-ol acetate and (E)-8-Dodecen- l-ol acetate for detection of tortricid moths Cydia lobarzewskii (Nowicki, 1860) and C. janthinana (Duponchel, 1835) and a binary mixture of (Z) and (E)-9-Tetradecen-l-ol acetate for detection of the pyralid Euzophera bigella (Zeller, 1848) were used. Males of C. janthinana were caught at all three locations under investigation. Their flight pattern characterized by a mid-August peak is illustrated. Three males of Cydia lobarzewskii were trapped at Pisek (first record from Bohemia). The presence of E. bigella was not confirmed. The flight patterns of Pammene spiniana (Duponchel, 1843) and P. aurana (E, 1775) are also presented. Details of male genitalia of all pheromone trapped species of the genera Cydia Hübner, 1825, Pammene Hübner, 1825 and Enarinonia Hübner, 1826 are illustrated and comments to determination, distribution and bionomics are given.
