Subject: Camphor Shoot Beetle, Xylosandrus mutilatus Blandford, detected in Mississippi and Florida
Date posted: October 01, 2002
The Camphor Shoot Beetle, Xylosandrus mutilatus Blandford, was detected for the first time in North America. In the spring of 2002 seven Mississippi (MS) counties confirmed the presence of X. mutilatus. Initial detections occurred in 1999. In late April of 2002 the beetle was also detected in central Florida (FL). It is not known if the FL detections are related to the situation in MS. All MS specimens were caught in Lindgren funnel traps leaving no live specimens to determine if the beetle vectors any phytopathogenic fungi. Typically only dead or dying wood is attacked by this Asian native, but without live catches on hosts this has yet to be confirmed. Xylosandrus mutilatus has a wide host range of hard and soft wood trees ranging anywhere from a ½- 2 inches in diameter. It survives in warm temperate to typical temperate climate zones. Spring detections are highest when the mated females are flying in search of new hosts. Surveys will be continued in MS and FL, with similar surveys being coordinated in Alabama and Tennessee to help delimit the infestation and understand the pathway of introduction.
