Variation in the susceptibility of some potato (Solanum tuberosum L.) cultivars to infestation with certain piercing sucking insect pests

Abstract :

Potato (Solanum tuberosum L.) is an economically important vegetable crop all over the world. The piercing sucking insect pests are a serious pests threatening potato plantations in many countries. The present investigation contributes to the knowledge on the susceptibility of certain potato cultivars to infestation with these insects in Beheira Governorate, Egypt. Five cultivars currently used in Egypt’s potato production were evaluated through two successive seasons (summer plantations) in field experiments for their susceptibility to sucking insect infestation. None of the tested potato cultivars was immune or highly resistant to the tested insect pests. The cultivars Banba and Diamante were found quite resistance to piercing sucking insect pests. The cultivars Herms was found as moderately susceptible while Spunta and Cara were found to be the most susceptible cultivars. The green lacewing, Chrysoperla carnea; seven-spotted lady beetle, Coccinella septempunctata; eleven spotted lady beetle, Coccinella undecimpunctata and the pirate bug, Orius sp. are the most important predators in the potato cultivars.
