Invasive alien wood borers: trapping studies in France


A survey programme on invasive alien wood borers has been carried out France in 2020. Traps of different colours and baited with a mixture of 8 pheromones to attract a wide range of insects have been placed in several sites: 8 points of entry (harbours, airports, nurseries, large markets), 11 forestry sites covering 7 different forest areas, 11 sites with a special focus on possible incursions of Aromia bungii and Xylosandrus spp. (9 in Southeastern France and 2 in Corsica). In total 94 insect species (6000 specimens), including the following alien species have been caught.

It is noted that Amasa truncata was first detected in 2018 in Antibes and is now probably established in eucalyptus plantations in Southeastern France. Aromia bungii was not caught during this survey. Surveys will continue in 2021 with two additional pheromones and including more points of entry.
