Résumé

A series of adult and larval ambrosia beetles were collected boring into twigs of coffee at a single site in a major coffee growing area. One of the adults was identified as X. compactus, the remainder were identified as X. morigerus (Blandford). Delineating surveys are yet to be conducted to determine the full extent of the infestation.

Danger

This circumtropical species is common throughout humid tropical and subtropical regions. Xylosandrus compactus has not previously been reported from Timor-Leste but is common in neighbouring countries so its presence in Timor-Leste is not surprising. The black twig borer is a major pest of coffee from Asia to Hawaii and is known to also attack other crops such as cacao, mango, avocado and macadamia. The female beetle bores into the heartwood and constructs galleries inoculated with an ambrosia fungus to feed both larvae and adults. The damage is caused by deep excavation of the host plant. Significant losses of coffee crop yields has resulted in extensive studies and implementations of trapping methods and repellent solutions around the world (Burbano et al., 2012). Xylosandrus compactus infests the twigs of a wide range of plant hosts but is unlikely to impact on the trade of coffee beans.
