9. Seasonal monitoring of the vine bud moth Theresimima Ampellophaga (Bayle-Barelle, 1808) by pheromone traps in the region of Kardzhali

The vine bud moth, Theresimima ampellophaga (Bayle-Barelle, 1808) is a pest on a grapevine, that can cause serious damage in vineyards in some regions in Bulgaria.

Delta sticky traps baited with the main synthetic sex pheromone compound, (2R)-butyl (7Z)-tetradecenoate, of Th. ampellophaga females were used for detection and seasonal monitoring of this species in vineyards in the region of Kardzhali (southern Bulgaria).

During the period of 2017–2018, two generations of this species were recorded in the region of Kardzhali. The flight period of the moths of the first generation was from the middle of June to the middle of July with a peak of flight in the second half of June.

The moths of the second generation occur from the middle of August until the first half of September. This is a new distributional record for this species in Bulgaria.
