Description The banana pseudostem weevil, Odoiporus longicollis Olivier (Coleoptera: Curculionidae) is an
important pest which affect the growth of banana and plantain in South East Asia [1]. Adult
females of O. longicollis lay eggs in the outermost leaf sheath of banana. Larvae hatched from
the eggs bore into the living tissue, producing frass- filled tunnels that weaken the affected parts
of the host plant and permit invasion of fungal and bacterial pathogens. Mature larvae pupate in
cocoons made from plant fibres close to the exit holes. Now a day, this weevil poses a serious
threat to the banana cultivation under garden land and highland of Tamil Nadu. A heavy loss of
yield was reported due to this pest. Therefore, an effective management programme for this
weevil is essentially required.
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.
