By screening singly and binary mixed 2,13- and 3,13-octadecadien-yl acetates and alcohols (2,13- and 3,13-18: Ac/OH)in Lithuania, Armenia, Azerbaijan, Turkmenistan, Ukraine, and the far east of Russia, sex attractants were discovered for 12 Sesiidae, four Tineidae, and one Choreutidae moth species. Males of Sesia yezoensis and Bembecia puella as well as Nemapogon flavifrons were attracted by mixture of Z3,Z13-18:Ac/OH in a ratio of 9:1, Pyropteron sp. n. by the same mixture (ratio 1:9), Bembecia romanovi and B. zuwandica by Z3,Z13-18:AC and E3,Z13-18:Ac (9:1), Synanthedon caucasicum by the same mixture in the opposite ratio (1:9), B. scopigera by 23,213-18:Ac and E2,Z13-18:OH in a ratio 9:1, Synasphecia triannuliformis by Z3,Z13-18:OH and E3,Z13-18:OH (9:1), Similipepsis takizawai and Archimeessia sp. n. by E3,Z13-18:OH and E2,Z13-18:Ac (1:1), Prochoreutis sechestediana by a mixture of E3,Z13-18:Ac plus E2,Z13-18:OH (1:), Microsphecia brosiformis by E3,Z13-18:Ac, Synanthedon conopiformis by the analogous alcohol, Synanthedon scoliaeformis and Nemaxera betulinella by E2,Z13-18:Ac, Triaxomera fulvimitrella by Z3,Z13-18:Ac. An analogous alcohol component is essential for the attraction of B. ichneumoniformis males. Inhibitors for B. romanovi, B. scopigera and B. zuwandica attraction were discovered. Preliminary data on attractants for six other species as well as on the diurnal rhythm of sexual activity of three species are presented. A new method for the stereoselective synthesis of 3,13-18:Ac/OH and E2,Z13-18:Ac/OH is described.
