abstract
Field experiments were carried out during the season Rabi 2016/17 at village Seetharamapuram, Perambalur, Tamil Nadu, India to evaluate the efficacy of Agro–Ecosystem Analysis (AESA) based Integrated Pest Management (IPM) practices with the farmer practice of spraying different insecticides against L. orbonalis on brinjal. The findings revealed that minimum brinjal shoot and fruit borer 8.9 per cent with highest abundance of parasitoids (5.82 nos.) in terms of different species occurred with least population of aphid and whitefly 2.16 and 1.19 numbers per three leaves whereas in farmers practices 25 percent incidence of brinjal shoot and fruit borer with minimum parasitoid recorded 1.15 nos and maximum population of aphid and whitefly (16.5, 14.58) respectively. The AESA based IPM practices that consisted of cultural and mechanical components itself proved to be an ideal management strategy against brinjal shoot and fruit borer along with a benefit: cost ratio of 3.03 whereas 2.19 in farmers practices.
