| Abstract:
Seasonal monitoring of the flight of the leopard moth borer, Zeuzera pyrina L. was conducted by pheromone traps in the experimental apple orchards of the Fruit Growing Institute and of the Agricultural University in Plovdiv (Central South Bulgaria) in the years 2002-2006. Two types of pheromone traps were used: Pherocon traps (Trécé, USA) with sticky changeable bottom and Mastrap (Isagro, Italy) dry funnel traps. The dispensers were products of Isagro, Italy. The traps were installed every year at the end of May and removed at the end of September. As a whole the flight of the leopard moth begins in the middle of June although in some years the first catches were recorded in the first decade of June. The mass flight was recorded mainly in July in all years of the study. The last catches were recorded at the end of August - beginning of September. The pheromone dispensers for Zeuzera pyrina L. have shown a good selectivity. No other species were caught in the traps. However, the catches were relatively low, considering that the population level of the pest, as estimated by injuries, was found to be quite high. No significant differences between the catches in sticky and dry traps was found in the orchards of the Fruit Growing Institute for all years of the investigations, but the catches on the dry traps were significantly higher than the catches on sticky traps in one of the orchards of the Agricultural University in both 2005 and 2006. The trend of seasonal flight in all orchards, estimated by the same kind of traps, sticky or dry, was very similar every year. The results of this investigation, which was carried out in Bulgaria for the first time, will be used for facilitating the usage of pheromone traps for this pest for the purposes of prognosis. | |
