Cosmopolites sordidus Marshall, G.A.K., 1930 - (banana weevil)

The weevil is believed to be native to the Indo-Malaysian region. It is now widely distributed in banana-growing regions, including the Americas and Africa, where it is a very important pest of bananas. The larvae bore in the corm, reducing nutrient uptake and weakening the stability of the plant. Attacks in newly planted banana stands can lead to crop failure.

The adults are black and 10-15 mm long and live for up to 2 years. They are free living, active during the night and most often associated with banana residues. They can be monitored by traps.

Control options include sanitation (destruction of banana residues), biological control, host plant resistance, botanicals, and (in some cases) pesticides. For details see Gold et al. 2001.
