Sirex woodwasp (Sirex noctilio) has been the most common species of exotic woodwasp detected at United States ports-of-entry associated with solid wood packing materials. Relatively little is known how significant its impacts will be to native pine trees as it has not yet spread into the southeast.
IPS Bark Beetles
There are three different species of Ips beetles (Ips avulsus, Ips caligraphus, Ips grandicollis) that attack all pine species in Tennessee. These beetles usually attack weakened or stressed trees and are almost always found in dying or recently cut pine trees with the bark still intact.
Black Turpentine Beetle
The black turpentine beetle (Dendroctonus terebrans) is the largest of the pine beetles and is most often a secondary pest. It can be found living in pines that have been previously infested by the southern pine beetle, freshly cut pine stumps or weakened or stressed pine trees.
Hackberry wooly aphid (Shivaphis cleti) is an introduced insect which feeds off the sap of hackberry leaves, excreting copious amounts of honeydew in the process. Often honeydew laden areas beneath infestation may be covered in black sooty mold growing off of the excreted sugar mixture.
Granulate Ambrosia Beetle
Granulated ambrosia beetle (Xylosandrus crassiusculus) attacks thin skinned deciduous trees in spring, feeding in the trees pith and introducing a tree killing symbiotic fungus. Characteristic symptoms are pencil sized strands of borer dust protruding from tree trunks.
