Apr 30, 2021 · The Southern Pine Beetle (SPB), Dendroctonus frontalis, is not much bigger than an eye gnat (Figure 1). It attacks and kills all species of southern yellow pines in Georgia, including white pines. Trees are killed when beetles construct winding S-shaped egg galleries underneath the bark (Figure 2).

Mar 29, 2024 · In the southern United States, southern pine beetle (SPB) prefers loblolly (Pinus taeda), shortleaf (P. echinata), pond (P. serotina), and Virginia (P. virginiana) pine. It has also been recorded infesting spruce pine (P. glabra) and sand pine (P. clausa).

The most diagnostic sign of SPB activity is the presence of the winding S-shaped galleries that cross over each other and are packed with boring dust and frass. These can be found by exposing a portion of the inner bark beneath pitch tubes or by removing a section of the bark.

Apr 30, 2021 · Pine bark beetles found throughout Georgia include the southern pine beetle (SPB), the black turpentine beetle (BTB), and three species of Ips engraver beetles, with a fourth found just in northern Georgia.

Winding S-shaped galleries: The most diagnostic sign of SPB activity is the presence of winding S-shaped galleries within the inner bark. These galleries intersect and are filled with boring dust and frass. They can be found by exposing a portion of the inner bark beneath pitch tubes or by removing a section of the bark.

adults often may be confirmed only by removing frass from feeding chambers on the inside of the bark or by removal of outer bark down to the area infested by the beetles (Fig. 10). Trees which have been vacated by SPBs

During outbreaks, the southern pine beetle may infest all pine species, and even marginal hosts such as spruce and hemlock may be killed. Populations often are concentrated in infestations or “spots.” Periodically beetle numbers may rapidly increase to outbreak levels, and healthy, vigorous pines may be at- Figure 1.

Dendroctonus frontalis, the southern pine beetle, [1] often shortened to simply SPB, is a species of bark beetle native to the forests of the southern United States, Mexico and Central America. [2]

Southern pine beetle (SPB) is a 1/8 inch to 1/4 inch wood-boring insect that infests pine trees, killing even large trees very quickly. It is one of the most destructive pests in the Southern and Southeastern United States. Preferred host trees include loblolly, shortleaf, and Virginia pine, although all species of pine are susceptible.

Aug 4, 2022 · Considered "the worst pest of southern forests," the southern pine beetle (SPB; Dendroctonus frontalis) has the potential to cause major destruction during outbreaks (Figure 5). Most years, SPB behaves as a secondary pest, attacking already-stressed trees.
