The oak buprestid beetle,Agrilus biguttatus (F.) (Col., buprestidae), a recent factor in oak decline in Europe

During last years, the populations of the oak buprestid beetleAgrilus biguttatus (Fab.) in Europe have increased. In several countries, the beetles’ attacks have become a new component in oak dieback. The larvae excavate galleries under the bark of weakened trees, which are killed through the girdling. Because of the difficult diagnosis it is necessary to draw more attention to the infestations. Therefore, this paper presents a review on the literature concerning the recognition of the infestations by the insect and its bionomics.
