Abstract
In the present field trials were conducted to survey the main prevailing insect-pests and /or beneficial ones on potato plants at El-Nobaria, district, El-Behiera Governorate, Egypt during the elapsing period from December 2014 up to April 2016. It was found that Potato plants are mainly attacked by a large number of insect pests such as Myzus persicae (Sulzer), Aphis craccivora Koch, Aphis gossypii Glover, Trichoplusia ni (Hübner), Liriomyza trifolii (Burgess), Phthrorimaea operculella (Zeller), Thrips tabaci Lind,and Empoasca lybica Beg. Besides, numerous species of  Natural Enemies particularly, Chrysoperla Carnea (Stephens), Paederus alfierii Koch, Syrphus corolla Fabricius and Coccinella undecimpunctata Linnaeus. The major abundant insect pest during both of the first and second winter growing seasons was Myzus persicae (31.6 and 106.8/15 plants, respectively) as well as both the first and second summer seasons (59.6 and 28.8/15 plants, respectively). Also, a positive relationship between Myzus persicae or/and Phthrorimaea operculella ,with temperature was detected, versus a negative inspected relationship with the relative humidity.
