| Abstract | ||||
| Two filed experiments were conducted during two successive seasons 2019 and2020 at the experimental vegetable farm of Asfaina,Toukh, Qalubiya Governorate, Egypt to study the effect of phytochemical composition of five snap bean(Phaseolus vulgaris L.) cultivars(Oxera, Falantino, Sebaries, Bronco and Golly) and their susceptibility to infestation with aphids(Aphis gossypii, Myzus persica and Aphis craccivora) and whitefly Bemisia tabaci. Results showed that Bronco and Oxera cultivars have higher population density of aphids increased with increase of percentages of the total protein, total carbohydrates, peroxidase, alpha esterase and beta esterase. While, decreased with the increase of total phenols. Oxera cultivar was considered the highest susceptible snap bean cultivar to B. tabaci infestation. On the other hand, the snap bean cultivar, Falantino was the highest resistant one. | ||||
