In Vilnius, Kairėnai a field screening test of 2E,13Z-, 3Z,13Z-, 3E,13Z-octadecadien-1-ols and their acetates (2E,13Z-, 3Z,13Z-, 3E,13Z-18:OH/OAc) as well as their binary mixtures was carried out and the attractivity of the mixture of 2E,13Z-18:OAc and 3Z,13Z-18:OAc to Synanthedon mesiaeformis males was determined. The test of the 2-component mixture in five different ratios in Eičiai (Tauragė district) revealed that mixtures containing 2E,13Z-18:OAc/3Z,13Z-18:OAc in the ratio from 9:1 to 5:5 were the most attractive. The mixture of 2E,13Z-18:OAc/3Z,13Z-18:OAc in the ratio from 49:1 to 9:1 attracted males of another clearwing moth species Synanthedon flaviventris. The mixture in the ratio 9:1 is recommended for the simultaneous attraction of the both mentioned clearwing species. To achieve species-specificity, the 2E,13Z-18:OAc/3Z,13Z-18:OAc mixture in the ratio 5:5 is recommended for S. Mesiaeformis, and the mixture of the same compounds in the ratio 49:1 for S. Flaviventris.
