![Banana corm damaged by banana weevil. Note tunnelling by weevil grubs and rotting of corm. Grubs tunnelling in the corm and rootstock do the most harm. The boring, if severe, weakens the plant so that it is easily knocked or blown over. Injury to the corm can interfere with root initiation and sap flow within the plant. (c) A. M.
