From 1948 to 1966 over a billion board feet of pine timber was killed during a series of outbreaks in the Southern States (fig. 86). It also occurs as far west as Arizona and south to Honduras. During a catastrophic outbreak in Honduras in the early 1960's, about 10 billion board feet of pine was killed. It breeds in all species of yellow pines in its range; also in white, red, and spruce pines, and red and Norway spruce. Shortleaf, loblolly, Virginia, and pitch pines appear to be most highly favored amo

Shortleaf, loblolly, Virginia, and pitch pines appear to be most highly favored among the yellow pines. Infestations in white pine are usually unsuccessful because of heavy exudations of pitch. Attacks on red spruce are also unsuc- cessful, the beetles dying in them after constructing short tun- nels (438).. m&fs.
