Recently it caused serious losses of apple trees in Syria. The flight dynamics of Z. pyrina was monitored by pheromone traps （first time in Syria） compared to light trap device. This study was carried out in Damascus countryside, Qunaytirah and Sweida provinces during 2007-2008. Results indicated that the flight of moths during 2007 started in early June in Damascus countryside and Sweida provinces. The highest number of caught adults （the highest peak） was concentrated in mid July in Sweida province, whereas in Damascus countryside province there were a high peak in mid June and a small peak in early July. On the other hand, flight of moths during 2008 started in mid-May in Damascus countryside province while in Qunaytirah province started in early June. The highest number of caught adults （the highest peak） was concentrated in late July in Damascus countryside, whereas in Qunaytirah province there were small peaks in mid June and mid July. Experiments conducted to evaluate capturing efficiency of different types of traps （pheromone traps and light trap） demonstrated that there was significantly high difference within the trap devices, wherein Capta trap got the best results and caught more males than the others.展开更多
