Citrus Longhorn Beetle Situation in Croatia – Two Years After the First Discovery

During the 2008-2009, 12 consecutive surveys of the quarantined nursery revealed 22 Acer palmatum plants and seven potted roses infested with CLB larvae in 2008, another 38 infested maples in 2009. Not a single Magnolia plant from the same imported batch revealed any sign of CLB presence as of October 2009. A switch from maple to nearby roses was recorded. Artificial introduction of CLB larvae demonstrated that they can thrive in Quercus, Robinia, Corylus, Malus and fully develop in Fagus sylvatica. Not a single sign of CLB infestation has been recorded in the area surrounding the quarantined nursery.
