Résumé : In coffee plantations, some of the coffee berry borer (#Hypothenemus hampei Ferrari#) females emerging from residual fruits survive by taking refuge in dry fruits remaining on the branches. They can then colonize new fruits as soon as they become appetizing and continue their development. The control strategy is therefore to capture part of the populations from residual fruits on the ground and eliminate fruit-refuges. CBB control is presented in the form of triple-action Integrated Pest Management: meticulous agronomic control of the coffee plantation, strict branch stripping and trapping. Agronomic control comprises coffee tree pruning, shade tree pruning and rehabilitation of the coffee plantation (cleaning). Branch stripping consists in picking and eliminating all the fruits that remain on coffee trees after harvesting. Trapping enables the capture of CBB during their migratory flights. Triple-action IPM experiments conducted in shaded coffee plantations have shown that it is possible to reduce CBB infestation by over 90% compared to control plots. Of the three IPM operations, only trapping requires any major investment. The advantages of this technique are numerous: efficient basis for control, no risk of contaminating the environment; it is a preventive strategy that is simple to apply, it is compatible with biological control and it does not affect biodiversity.
