Studies on biology of leaf miner, Liriomyza trifolii were carried out on tomato plant in the Plant Protection Laboratory of Department of Agricultural Entomology, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal. The egg, first instar larva, second instar larva, third instar larva and pupa measured about 0.21 ± 0.03 mm x0.11 ± 0.02 mm, 0.54 ± 0.07 mm x 0.33 ± 0.07 mm, 1.41 ± 0.06 mm x 0.5 ± 0.04 mm, 2.09 ± 0.02 mm x1.19 ± 0.04 mm and1.78 ± 0.09 mm x0.68 ± 0.06 mm in length and breadth, respectively. The length of body and wing expanse in adult male and female were found to be in a range of 1.46 ± 0.08 mm and 1.22 ± 0.06 mm, 1.68 ± 0.09 mm and 1.35 ± 0.07mm, respectively. The biological studies of L. trifolii under different temperature regimes of 15°C, 20°C, 25°C and 30°C revealed that the duration of egg, larva, pupa and adult stages were longest at 15°C and shortest at 30°C. The total developmental period observed at 15°C,20°C,25°C and 30°Cwere: ♂- 60.5 ± 1.40 days; ♀- 63.2 ± 1.46 days, ♂- 37.4 ± 1.22 days; ♀- 39.8 ± 1.36 days, ♂- 26.4 ± 1.12 days; ♀- 28.6 ± 1.10 days and ♂-16.4 ± 0.96 days; ♀- 17.9 ± 0.98 days, respectively.
