INTEGRATED MANAGEMENT OF ZEUZERA PYRINA L. IN POMEGRANATE ORCHARDS USING ENVIRONMENTALLY SAFE TREATMENTS

Abstract

Alternative non-conventional and environmentally safe means (sex pheromone mass trapping, horticultural, mechanical, microbiological and local chemical treatments) for reduction Zeuzera pyrina L. infestation, were evaluated in infested pomegranate orchards during three successive years (2005, 2006, and 2007) at Wady El-Natroun district, Behera governorate.Z. pyrina infestation was reduced by 59.78, 68.92 and 80.00% due to whole year pheromone treatment, 56.87, 80.15 and 88.21% due to pruning treatment, 36.76, 55.85 and 65.03% due to worming treatment, 7.92, 12.77 and 17.48% due to bacterial treatment, 6.23, 11.38 and 15.89% due to fungal treatment, 68.26, 79.69 and 84.23% due to whole year local spraying, 60.99, 75.38 and 81.99% due to whole year local painting, 83.52, 92.15 and 96.29% due to whole year complete coverage spraying, when applied for 1, 2, and 3-successive years, respectively. The respective combined treatments resulted in 71.41, 85.85 and 92.58% due to partial pheromone and pruning, 47.18, 62.00 and 74.30% due to partial pheromone and worming treatments, 31.72, 40.62 and 52.84% due to partial pheromone and bacterial treatment, 28.81, 38.77 and 51.52% due to partial pheromone and fungal treatment, 81.36, 92.46 and 96.03% due to partial pheromone and local spraying, 78.69, 91.38 and 94.44% due to partial pheromone and local painting and 65.38, 77.69, 83.97% due to partial pheromone and complete coverage spraying
