Sampling techniques currently used to determine control
measures for the Coffee Berry-borer (CBB) are time-consuming and allow the grower only a small
window of opportunity to select other options. Experiments were conducted in four coffee fields
between 2005 and 2007 using IAPAR (R) traps that were baited with ethanol and methanol (1 : 3
ratio) and benzaldehyde at 1% volume, to test for a correlation between the number of captured
adults and infestation levels of CBB, and to determine the action threshold level. For this
study, a density 20 traps/ha was used in each experimental area. The number of CBBs captured and
infestation level on coffee berries were recorded every 2 weeks. Significant correlation was
observed between the trap capture and the infestation level of the CBB in the field. This
correlation can enable us to determine action thresholds using traps as sampling methods. Trap
catch was very low in all four fields during fruit maturation between March and July, and it
increased sharply in August when the CBB emerged from the dry berries that remained on the plants
or on the ground.
