Abstract:Two field experiments were conducted at Beni-Suef governorate during the early and late recommended sowing seasons 2010 to evaluate three potatoes (Solanum tuberosum L.) varieties; Diamant, Lady Rossetta and Burren for their relative susceptibility to mite, Polyphagotarsonemus latus (Banks) and aphid insect, Aphis craccivora Koch infestation. Obtained data revealed that Burren variety was susceptible to mite and intermediate to aphid insect infestation, where it aggregated (1436&2502) and (273.7&372.1) of mites and aphids during early and recommended seasons. While, Diamant variety was highly tolerant, which horbouing (476&529) and (120.9&182.2)at the same trend. But Lady Rosstta variety was intermediate for mite and susceptible for aphid insects . In general the level infestation of both mite and aphid pests were high during the early season than recommended sowing season.
