Abstract

The present experiments were conducted in a private cucumber field in Ibshwai, Fayoum governorate during the two successive years (2018 and 2019) to examine the influence of different cucumber varieties on the occurrence of the piercing-sucking insect pests in Fayoum governorate.

Cucumber variety Hayel F1 hybrid followed variety Mayadine F1 hybrid hosted the lowest average number of the aforementioned insect pests during the two years. Cucumber variety Hayel F1 hybrid followed by Mayadine F1 hybrid, Reda F1 hybrid and Sweet Cransh F1 hybrid hosted the lowest average number of the green sting bug Nezara viridula followed by the cotton mealybug Planococcus solenopsis and the onion thrips Thrips tabaci during the two years.
