Susceptibility of some Broad Bean Plant Varieties to the Infestation by Certain Piercing Sucking Insects, Egypt.
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.
