The banana pseudostem weevil infestation in Region XI

Issue Date

Abstract

The banana stem weevil (BSW) or banana pseudostem borer Odoiporus longicollis Olivier (Coleoptera: Curculionidae), is a pest of considerable importance recently and affects banana production. It has been observed that the weevil is associated with rapid decline of banana yield particularly in small farms in Region XI where banana is grown extensively. Generally, high infestation of the banana pseudostem weevil is observed in Davao del Norte where majority of the resource-limited small farmers are cultivating banana as a subsistence crop. The pest confines itself within the pseudostem and in the decomposing tissues of harvested pseudostem. All life stages of the weevil are present in the infested plants throughout the year. Weevil infestation interferes with the translocation of nutrients and water, retards plant growth and development and increases susceptibility of the banana plant to wind lodging which is very similar to nematode infestation. The problem is generally notice in advanced stage when the infesting grubs are already fully grown.
