Abstract :
This study was conducted under laboratory conditions at 25±1 °C, % 65±5 relative humidity and 16:8 LD photoperiod. The developmental period, mortality rates and life tables of Tuta absoulta on the potato varieties of Alegria, Marabel, Marfona and Lady Olympia were studied Total developmental durations of the immature stages were 24.22, 21.00, 25.75 and 27.50 on the potato varieties of Alegria, Marabel, Marfona and Lady Olympia, respectively. Total mortality rates of the immature stages were 26.7, 33.3, 30 and 40% on the potato varieties of Alegria, Marabel, Marfona and Lady Olympia, respectively. The life-tables’ parameters of Tuta absoluta on Alegria, Marabel, Marfona and Lady Olympia patato varieties were found for net reproductive rates (R0) as 13.39, 8.31, 8.25 and 4.98 females/females/generation, intrinsic rate of increase (rm); 0.088, 0.081 and 0.073, 0.056 females/female/day, mean generation time (T0); 29.6, 25.7, 29.0 and 28.7 day, respectively. When all parameters investigated, it was found that T. absoluta could complete their devolopment and be reproduced on all potato varieties. But, Alegria was determined as the most suitable variety fort tis pest.
