ABSTRACT
The life table studies of spotted bollworm Earias vittella (Fab.) on cotton were conducted for three generations corresponding to the vegetative and early flowering, peak flowering and fruiting and boll development and maturation stages of the crop. Based on ‘K’ values, unknown factors (predation and adverse climatic factors) were identified as key mortality factors during larval phase II of E.vittella.
