摘要

Banana stem weevil, Odoiporus longicollis (Olivier) (Coleoptera: Dryophthoridae) (Fig. 1) is the major pest of banana in South and South East Asia, especially inIndia (Visalakshi et al., 1989; Padmanabhan and Sathiamoorthy, 2001 and Azam et al., 2010). Adult females lay eggs in the air chamber present in the pseudostem and emerging grubs feed on leaf sheath and sometimes reaching up to peduncle (Padmanaban et al., 2001); pupate in a cocoon made of banana fibers. All stages except adults are seen inside the stem. Damage is caused by feeding grubs which make extensive tunnels on the stem and weakens the plant. Infested plants will topple down especially at fruitemergence. In severely infested plantations, more than 20% plants do not flower, if attacked in the advanced preflowering stage. It is also estimated that the weevil causes 10-90% yield loss depending on the growth stage of the crop and management efficiency (Padmanaban and Sathiamoorthy, 2001).
