A simple and low cost semiochemical based trapping method for the management of banana pseudostem weevil, Odoiporus longicollis Olivier (Coleoptera:Curculionidae)

Aggregation pheromone of banana pseudostem weevil, Odoiporus longicollis in conjunction with host plant extract was used to develop an efficient trapping method to monitor and control the pest. In a field experiment, funnel traps baited with the lure of aggregation pheromone, 2- methyl-4-heptanol in combination with host plant extract attracted significantly more weevils than traps baited with either pheromone or host plant extract alone. Semiochemical based trapping in weevil management has potential either in mass trapping or as part of an integrated pest management (IPM) programme.
