The turpentine borer, Buprestis apricans Hbst., long considered the most important eastern member of the genus, occurs through- out the southern coastal regions from North Carolina to Texas, and breeds in longleaf, slash, loblolly, shortleaf, and pitch pines. The adult (fig. 48) is grayish-bronze with a greenish, metallic lustre and is about 25 mm. long. It is elliptical, somewhat flat- tened, and each elytron bears eight rows of large punctures.

The turpentine borer, Buprestis apricans Hbst., long considered the most important eastern member of the genus, occurs through- out the southern coastal regions from North Carolina to Texas, and breeds in longleaf, slash, loblolly, shortleaf, and pitch pines. The adult (fig. 48) is grayish-bronze with a greenish, metallic lustre and is about 25 mm. long. It is elliptical, somewhat flat- tened, and each elytron bears eight rows of large punctures. Full-grown larvae have the prothoracic plates roughened and marked above by a dark brown Y, and they are up to 40 mm. long. Turpentine borer beetles emerge in February or March and feed for a short time on the needles in the tops of their hosts. Eggs are deposited in exposed wood containing season checks, especially at the edges of turpentine faces and on fire-scarred sur- faces. The larvae tunnel in the sapwood and heartwood, construct- ing long, narrowly oval, tortuous mines and filling them with solidly packed, fine, granular, pitchy frass. At maturity, they form cells in which to pupate near the surface. There the adult spends the winter. About 3 years are spent in the larval stage. The turpentine borer used to be the most destructive insect in the turpentine orchards of the South {38, W). Borer riddled trees were weakened so severely, they became subject to wind break- age. The lumber value of such trees was virtually destroyed, and gum production was seriously reduced. Attacks can be prevented or reduced through the exercise of care in preventing the ex-.
