Field experiments were conducted during 2014/15 and 2015/16 seasons at Sakha, Kafr El-Sheikh governorate to survey arthropods associated with potato var. (Cara) and the population fluctuations of the main arthropod species in winter plantation. Also, efficiencies of certain compounds; Aveo & Indoprem (indoxacarb), Warnt (imidacloprid), Twistrid (acetamipirid), Kz oil, eucalyptus oil and garlic oil  in reducing the population density of aphids (Aphis gossypii,, Myzus persicae  and Macrosiphum sp.), Bemisia tabaci and Empoasca spp. were evaluated. In addition, their side effects on predators and chlorophyll content in potato leaves were evaluated. The investigation revealed the presence of 20 arthropod species were 15 families and 12 orders. Among the surveyed arthropods, 12 species were recorded as pests and eight species of beneficial arthropods on potato plants. Aphids constituted the greatest number followed by B. tabaci and Empoasca spp. Nezara viridula appeared in few numbers. Beneficial arthropods, Scymnus sp. constituted the greatest number but P. alfierii was recorded in few numbers. The highest population densities of M. persicae were recorded in December, and February. The highest population densities of B. tabaciwere recorded in November, December and January, while leafhoppers were recorded in December and January. Scymnus sp. population was recorded in November, December, January and February. Peaks of C. undecimpunctata occurred in November and December, while spider populations were recorded in December and January in the two seasons. Twistrid was the most potent compounds in reducing the population density of Aphis spp., while garlic oil showed a low effect. Twistrid was the most potent compound in reducing B. tabaci eggs and adults also, Aveo had same effect in reducing B. tabaci immatures. Garlic oil showed a low effect in reducing B. tabaci immatures and adults while Warnt showed the lowest effect on whitefly eggs. All the tested compounds gave good effect in reducing Emposaca spp.Warnt was the most potent compound in reducing the population density of leafhoppers but eucalyptus oil showed a low effect. Warnt and Aveo induced a high effect on predators while garlic oil induced the lowest. All applications did not affect significantly on chlorophyll content.
