Abstract
These experiments were carried out at Abo-Hammad district, Sharkia Governorate, during two growing seasons of  broad bean plants (2016 / 2017 and 2017/ 2018). Some varieties of  broad bean plants (Sakha 1, Giza 3 and  Giza 843)  to infestation with some aphid, leafhopper and whitefly insects and the effect of some chemical contents (protein, carbohydrate and pH values) to varieties of  broad bean plants on the infestation of certain investigated insects. The obtained results cleared that Aphis craccivora (Koch) and  Myzus persicae (Sulzer) had two peaks on broad bean plants. One peak occurred for both Empoasca decipiens (Paoli) and  Empoasca decedens (Paoli) during the two seasons. The whitefly (immature and adult stages),  Bemesia tabaci (Genn) was the most abundant species showing two peaks . The effect of each of maximum, minimum temperature and relative humidity on the numbers of certain piercing sucking insects, it is obvious that the effect was clear. The obtained results showed that broad bean varieties could be arranged descendingly according to the number of pests as follows: Giza 843, Giza 3 and  Sakha 1. Chemical analysis results showed an increase in protein and carbohydrate contents led to increase the mean number of some pests infesting these varieties, while increased of pH values led to decrease the mean number of pests and rate of infestation.
