Abstract :
The life history of the tomato leaf miner, Tuta absoluta (Meyrick) [Lepidoptera:Gelechiidae)] was studied under the laboratory conditions in 2013 year. For this purpose, development and survival of immature stages, adult longevity, fecundity and ovipositon period of T. absoluta were studied. According to the results, it was determined that the width of the head capsule of larvae for first, second, third and fourth were 0.15, 0.29, 0.39 and 0.75 mm respectively. It was determined that the length of egg hatching was 4.10 days. Total period of larvae instar was 10.97 days. The period of pupae development was 9.53 days. Fecundity of T. absoluta was found 141.16 eggs/female. Preoviposition period was 1.28 days. Oviposition and postoviposition periods were 7.88 and 5.52 days respectively. The intrinsic rate of increase (rm), finite population increase (λ), net reproductive rate (Ro) and mean generation time (To) of T. absoluta were 0.132 day^-1, 1.141day^-1, 42.01 and 28.25 days respectively. The life expectancy of a newborn egg was 42.60 days. All of experiments were conducted in a climate chamber at 25±1°C, relative humidity 65±5% and under long daylight (16L:8D).
