Abstract

Laboratory experiments were carried out to investigate some biological characteristics of some lepidopteran insect pests infesting tomato plants, when reared on tomato leaves at constant temperature of 27±2ºC and 65±5% RH. These insects were Tuta absoluta (Meyrick), Spodoptera littoralis (Boisd.) and Spodopera exigua (Hb). These experiments were conducted in the laboratories of Plant Protection Research Institute, Mansoura Branch. Results showed that the incubation period of the eggs stage averaged 3.0; 4.2 and 4 days for T. absoluta, S.exigua and S. latorallis when reared on tomato leaves respectively. Whereas, The duration of the larval stage of averaged 13.0; 15.3 and 13.5 days when reared on tomato leaves, respectively.The pupal stage lasted 3.7; 6.3 and 4.4 days for these insects respectively. The total immature development lasted 21.3; 26.7 and 22.9 days respectively. The obtained results indicatyed that female longevity lasted 5.9; 8.3 and 6.2 days for T. absoluta, S. exigua and S. latorallis respectively. The fecundity per female was 280; 480 and 870 eggs, respectively.
