Rat damage assessment and control in cocoa
Rat damage to cocoa in Fiji is widespread, and serious on some properties. Damage occurs as the pods turn yellow at maturity so all pods attacked are a total loss. Attack rates exceeding 9000 pods (500 kg dry cocoa) per hectare have been recorded. Damage can be reduced to very low levels by baiting with warfarin impregnated wheat set in paraffin wax (commercial preparation). Two to three applications of poison per year (depending on plantation size) with the first being placed at the start of the harvest season provides very satisfactory control
