New results of testing the attractant EFETOV-2 in the Far East of Russia, Siberia and South Africa

The sex attractant butan-2-yl dodec-2-enoate (a patented name ‘EFETOV-2’) synthesised at the Crimean Federal University was tested in the Far East of Russia and Eastern Siberia in 2022 and the Republic of South Africa in 2019. The males of three Zygaenidae species (Lepidoptera) were attracted in our field experiments, viz. Illiberis (Nikilliberis) kardakoffi Alberti, 1951, Rhagades (Rhagades) pruni ([Denis & Schiffermüller], 1775) (both Procridinae) and Praezygaena ochroptera (Felder, 1874) (Zygaeninae). For I. (N.) kardakoffi and P. ochroptera data on attractants were not previously known.
