abstract
The non-replicated field experiment on field-life tables of pink bollworm infesting Deshi cotton was conducted at the Experimental Farm of College of Agriculture, Latur (MS) India, during kharif 2016. On Deshi cotton, early instar larvae of Pectinophora gossypiella were died to the extent of 11.85, 12.7 and 19.2 per cent due to unknown reason during first, second and third generation, respectively. However, its 13.4, 8.92 and 7.9 per cent early instar larvae were also killed due to Apanteles during first, second and third generation, respectively. Late instar larvae of P. gossypiella were died to the extent of 5.3, 4.4 and 3.8 per cent due to Apanteles during first, second and third generation, respectively. Whereas, its 8.7, 5.8 and 10.34 per cent late instar larvae were also killed due to unknown reason during first, second and third generation, respectively. Unknown reasons also caused pupal mortality of P. gossypiella to the extent of 3.3 and 4.99 per cent in first and second generation, respectively. The maximum contribution towards generation mortality of P. gossypiella came from early instar larvae in all the three generations (k = 0.1175, 0.099 and 0.12). Total K for first, second and third generation was 0.195, 0.167 and 0.184, respectively.
