Abstract. The vine bud moth, Theresimima ampellophaga is considered as a pest species of the grapevine Vitis vinifera in Bulgaria. Delta sticky traps baited with the main synthetic sex pheromone compound, (2R)-butyl (7Z)-tetradecenoate, of Th. ampellophaga were used for detection and seasonal monitoring of this species in vineyards at four sites in Bulgaria – Lozitsa village (Municipality Nikopol) (northern Bulgaria) and Gornoslav village (Municipality Asenovgrad) in 2015 and 2016, and Plovdiv town and Krumovo village (Municipality Rodopi) (southern Bulgaria) in 2015. Catches of Th. ampellophaga males were recorded only in the villages of Lozitsa and Gornoslav. These are new distributional records for this species in Bulgaria. At these two sites, only one generation of Th. ampellophaga was established in 2015. In 2016, one generation of this species was recorded in Lozitsa and two generations – in Gornoslav. The flight period of the moths of the first generation was from the end of May (Gornoslav) – middle of June (Lozitsa) to the second half of July at both sites. The moths of the second generation in Gornoslav occur at the second half of August.
