Abstract

    The coffee berry borer (CBB) [Hypothenemus hampei (Ferrari)] is one of the most serious coffee pests worldwide. Existing methods to collect CBB adults from infested coffee berries are extremely labor intensive and time consuming. In order to develop an productive technique to collect CBBs, a commercial insect breeder was selected as a prototype of the collection device to evaluate the effectiveness of the additional bridge, the bridge texture, and light source of the device. The results showed that the device had the optimal collection efficiency when a strip of paper was added as a bridge to connect the berries in the bottom container to the top collection cup, and when the funnel and the bottom container were covered with aluminum foil to make the light source come only from the top, while the textures of the paper bridge had mininal effect on collection efficiency. This modified collection device provides a better way to collect CBB adults for further research or applications.

Key words: Coffee berry borer, Hypothenemus hampei, Collection method.
