SEASONAL VARIATION OF THE GREEN BEANS APHID, APHIS CRACCIVORA KOCH AND ITS NATURAL ENEMIES ON THE GREEN BEANS PLANTS, PHASEOLUS VULGARIS L. AT MENOUFIA GOVERNORATE
Population density of Aphis craccivora attacking green beans plants cultivated at Ashmoon, Menoufia cleared that the summer season was the highest abundance , since the total average recorded 3226.0 immature insects / 10 leaves and 340 mature insects /10 leaves , whereas in the winter season the total numbers average 81.1 immature insects /10leaves and 60.0 mature insects /10 leaves . The percentages of predators to aphid numbers reached to 34.1 and 19.7 5 in both seasons of study, respectively.
