“…For the study of insect population dynamics, life tables are valuable as they present a suitable method for recording and accounting for population changes in an insect's life cycle (Nanthagopal and Uthamasamy, 1989) and provide most comprehensive account of the development, survival and fecundity of an insect population (Price, 1997;Rickets and Miller, 1999;Gaikwad et al, 2018). Biology and life history performance of S. dorsalis on different hosts was studied by a few researchers (Dev, 1964;Das, 1965;Seal et al, 2010;Duraimurugan and Jagadish, 2011;Rahman et al, 2014;Saha, 2016). Dev (1964), Das (1965), Rahman et al (2014) and Saha (2016) have studied the biology and development of S. dorsalis on tea plants in India.…”
