DSC 0651  Longitudinally split pseudostem pieces can be used as traps for monitoring and trapping of banana pseudostem weevil and corm weevil. DSC 0650  Longitudinally split pseudostem pieces attract greater numbers of corm weevil than pseudostem weevil. DSC 0646  Longitudinally split pseudostem pieces can be used as traps for monitoring and trapping of banana weevils.  These traps should be frequently visited to collect and kill the adult weevils. DSC 0621  Disc-on-stump traps can also be used for monitoring and trapping of banana weevils and are better than longitudinally split traps.
DSC 0618  Insecticides / entomofungal pathogens like Beauveria bassiana may be applied onto the cut surface of the stump and covered with another disc of pseudostem to make the trap more effective.
