| Abstract | ||||
| At Faculty of Agriculture farm, Mansoura district, Dakahlia Governorate, field experiments were conducted with broad bean plants over the course of two seasons. (2020/2021 & 2021/2022). The consequences of different chemical compositions (protein, pH values, and carbohydrates) three different bean plant varieties were compared to types of broad bean plants and the insects that were evaluated for infestation. (Giza 716, Nubaria, and Giza 843) and their infestation with some whitefly, leafhopper, and aphid insects. According to results showed that that on broad bean plants, Myzus persicae (Sulzer) and Aphis craccivora (Koch) had two peaks. During the two growth seasons of the study, there was a single peak for Empoasca decipiens (Paoli) and Empoasca decedens (Paoli). The most common species of whitefly with two peaks was Bemesia tabaci (Genn), both in its juvenile and adult phases. The populations of specific piercing sucking insects were examined in relation to the effects of the maximum, minimum, and relative humidity. Based on the data gathered, it was possible to organise the broad bean varieties Nubaria, Giza 716, and Giza 843 in decreasing order of pest abundance. The findings of a chemical study revealed that while pH levels reduced the rate of infestation and the mean number of pests, increases in carbohydrate and protein contents increased the mean number of different insect pests that infesting these kinds. | ||||
