Biology of tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) under laboratory condition.
The study on biology of tomato leaf miner, Tuta absoluta (Meyrick) was carried out during 2015-16. All the experimental studies were conducted in the controlled conditions (28°C Temp and 70% RH) at the Main Agriculture Research Station, Raichur, Karnataka. The results revealed that, egg, first, second, third and fourth larval period was 4.08±0.55, 3.48±0.64, 1.78±0.40, 1.90±0.44 and 3.43±0.58 days respectively with total larval period of 10.59±2.06 days. The pre-oviposition and oviposition period found to be 1.33±0.33 and 11.55±0.92 days, respectively. The fecundity varied from 165.05±6.22 eggs per female. The longevity of adult male was 7.50±1.20 days and female 15.01±1.47 days. The male and female of T. absoluta occupied 29.76±3.92 and 37.30±4.88 days, respectively to complete total life cycle.
