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.
