ABSTRACT
Sex attractants for 3 Sesiidae and 3 Tineidae moth species in West-Kazakhstan and Lithuania were discovered by field screening tests of (3Z,13Z)-, (3E,13Z)- and (2E,13Z)-octadecadien-1-ols and their acetates as well as of some binary mixtures of these compounds. Total amount of chemicals was 0.3 mg/dispenser. Males of Synanthedon serica were attracted by a 5:5 mixture of 3E,13Z-18:OAc and 2E,13Z-18:OAc, Chamaesphecia bibioniformis by a 9:1 mixture of 3Z,13Z-18:OAc and 3E,13Z-18:OAc, Paranthrene tabaniformis by a 1:9 mixture of 3Z,13Z-18:OH and 3E,13Z-18:OH, Tinea nonimella by a 1:9 mixture of 3E,13Z-18:OH and 2E,13Z-18:OH, Monopis monachella by a 1:9 mixture of 3Z,13Z-18:OH and 2E,13Z-18:OH, and Nemaxera betulinella by a 9:1 mixture of 2E,13Z-18:OAc and the corresponding alcohol. The periods of attraction to the traps were registered for males of S. serica and Ch. bibioniformis and were found to occur at 15-18 and 15-17 o'clock, local time, respectively.

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 ofSesia yezoensis andBembecia puella as well asNemapogon flavifrons were attracted by mixture ofZ3,Z13-18:Ac/OH in a ratio of 9â¶1,Pyropteron sp. n. by the same mixture (ratio 1â¶9),Bembecia romanovi andB. zuwandica byZ3,Z13-18:Ac andE3,Z13-18:Ac (9â¶1),Synanthedon caucasicum by the same mixture in the opposite ratio (1â¶9),B. scopigera by 23,213-18:Ac andE2,Z13-18:OH in a ratio 9â¶1,Synasphecia triannuliformis byZ3,Z13-18:OH andE3,Z13-18:OH (9â¶1),Similipepsis takizawai andArchimeessia sp. n. by E3,Z13-18:OH andE2,Z13-18:Ac (1â¶1),Prochoreutis sechestediana by a mixture ofE3,Z13-18:Ac plusE2,Z13-18:OH (1â¶),Microsphecia brosiformis by E3,Z13-18:Ac,Synanthedon conopiformis by the analogous alcohol,Synanthedon scoliaeformis andNemaxera betulinella byE2,Z13-18:Ac,Triaxomera fulvimitrella byZ3,Z13-18:Ac. An analogous alcohol component is essential for the attraction ofB. ichneumoniformis males. Inhibitors forB. romanovi, B. scopigera andB. 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 andE2,Z13-18:Ac/OH is described.
