Abstract The field study carried out at farmers field in Jorhat district during 2011–12 and 2012–13 revealed that the module comprising of four components viz., pheromones, neem pesticides, removal of infested shoots and plastic mulch (M3) was most effective in reduction of 85.0% shoot damage followed by 79.5, 75.5 and 46.5 per cent in M2, M4 and M1, respectively. This module also recorded the highest protection in fruit damage (74.0%) followed by 65.2, 63.4 and 53.95 per cent in M2, M4 and M1, respectively. The shoot damage and fruit damage were recorded to be the lowest (3.0%) and (13.0%), respectively with installation of pheromone traps in an integrated mode rather than the pheromone traps alone being 10.7% and 23.1%, respectively. Pheromone traps in integration with neem pesticides was found effective in controlling the shoot and fruit damage rather than the use of pheromones alone with 32.8 per cent increase in yield over control.
