Abstract

Effects of different verities of potato tubers as a food Cara, Spunta and Rosetta on food ability, developing, fecundity and life table parameters of Phthorimaea operculellawere studiedunder laboratory conditions.Egg incubation period was longest in time when Ph. operculella reared as larvae on Rosetta variety and spent 5.5 day. The natural mortality data for larvae reared on Cara variety were 23.14, 19.67 and 2.4%, respectively. Pupal duration which reared on the potato varieties Cara, Spunta and Rosetta were 9.22, 10.68and 12.23 days, respectively. Duration of the generation was 40.90 and 35.9 days, on Cara and Spunta varieties, respectively. The obtained results indicate that potato variety Cara demonstrated the highest net reproductive rate (37.7 eggs/female) followed by Spunta variety (22.7 eggs/female) and Rosetta variety (16 eggs/female)
