    Introduction:
    Species Notes for this Location:
    In its native coniferous forests in North and Central America the red turpentine beetle is generally harmless and of little economic importance (Smith 1971, Furniss & Carolin 1997, Wood 1982, in Cai et al. 2008). It may kill pines in plantations and may predispose pines to attack by other bark beetles (Rappaport et al. 2001, Owen et al. 2005, in Cai et al. 2008).

    Impacts:
    Reduction in native biodiversity: Despite its abundance and wide distribution D. valens has not generally produced extensive or severe outbreaks in North America (Smith 1971, Cibrian-Tovar et al. 1995, in Liu et al. 2006). However, recently it has been causing moderate mortality among ponderosa pines in a thinned, subsoiled plantation near Pondosa (California, USA) and Mexico (Britton and Sun 2001, Rappaport et al. 2001, in Liu et al. 2006).
