Abstract
The peach twig borer (PTB), Anarsia lineatella Zell., and the oriental fruit moth Cydia molesta (OFM) Busck are the main pests of apricot in Bulgaria.
The main objective of this study was to test the possibility of using mating disruption (MD) as an alternative method to control both pests.
The experiment was carried out in an isolated apricot orchard, established in spring 2003 in north-east Bulgaria.
In the years 2008-2009 mating disruption (MD) was tested using Ecodian Combi CM+AL pheromone dispensers (ISAGRO SpA, Italy). Dispensers were installed twice per season at 60-day intervals.
In both years, MD totally suppressed captures of male moths in orfamone and anemone baited traps in the trial plot.
Fruit damage in the MD-treated plot was low, from 0 to 0.1-0.2% at harvest.
The results have confirmed that applications of Ecodian Combi CM+AL dispensers can provide more effective control of peach twig borer and oriental fruit moth than the conventional protection programme commonly applied in Bulgaria and should be implemented in commercial apricot production.
This friendly approach to controlling peach twig borer and oriental fruit moth is in line with the recent EU recommendations that take care of preservation of the natural environment and of production of healthy fruits, with no pesticide residues.
