| Abstract | ||||
| Faba bean (Vicia faba L.) is the main source of plant proteinsin Egypt. Thiscrop is attacked by numerous of pests as mites , Aphids ,white fly and leaf hoppers. Unfortunately these pests contribute to transmit viral diseases . The experiment was carried out Sakha Agricultural Research Station , Kafr El-Sheikh Governorate and conducted in 2013/2014 season to determine theage distribution patterns of pests and predators as a method for predicting the reproductive capabilities and probability of the continuation of arthropods species in the future .In addition tothe relationships between phenols leaf contentand occurrence of arthropods was studied. Populations of sucking pests and their natural enemies on leaflets of different cultivars of faba bean; Giza 716, Sakha 3 and Giza 40 were recorded. Theage distribution patterns of the above mentioned arthropods were represented by three patterns are expanding population, decline population and stationary population. Decline age distribution was found for phytophagous mite; Tetranychus urticae Koch on Giza 716 cultivar which means that the mite population is decreasing . The population of age distribution of Aphis Giza 716 spp. stages appeared as expanding population on the three faba bean cultivars. The population of age distribution of Empoasca sp. was expanding on Giza 716 and Giza 40 cultivars of faba bean ,but it declining on Sakha 3 cultivar. However the three age patterns were found for Chrysoperla carnea Steph., expanding for Aphidoletes aphidimyza (Rond.). Data revealed that the correlation between total phenols in faba bean leaflets were significantly positive only in Sakha 3 cultivar . | ||||
