A scientific note on rapid host shift of the invasive dusky sap beetle (Carpophilus lugubris) in Italian beehives: new commensal or potential threat for European apiculture?
Apidologie 45 (4), 464-466
Abstract: The dusky sap beetle (DSB) Carpophilus lugubris Murray 1864 (Coleoptera, Nitidulidae, Carpophilinae) is a Nearctic species, usually associated with fermenting sweet corn (Dowd 2000, 2005), and other rotting vegetable matter, but is not known to occur within honeybee colonies in that region (Ellis et al. 2008).
The first known records of DSB in Italy or Europe as a whole, and also the first record of this species associated with beehives has been observed by the authors in April 2011 (Marini et al. 2013); however, the host substrate via which DSB was introduced to Italy remains unknown.
This scientific note reports new data on the occurrence of DSB in beehives in Northeastern Italy, and discusses the implications of this "host shift" to honey bee health. These new reports show that DSB Italian populations are often associated with beehives and that they appear to be in dissemination.
Occurrence of DSB (April 2011-May 2013) was reported in 22 beehives in 6 localities of Veneto and Friuli-Ve
