Longhorn beetles from postharvest woods in Vietnam

This study surveyed longhorn beetles in harvested woods in Hoa Binh and Vinh Phuc provinces, Vietnam. Seven harvested wood species were examined after having detected the presence of longhorn beetles: Acacia mangium Willd. Acacia hybrid, Chukrasia tabularis A. Juss., Eucalyptus urophylla Blake, Eucalyptus hybrid, Pinus caribaea Morelet and Pinus massoniana Lamb. Eucalyptus hybrid and P. massoniana were the most commonly attacked trees with 23.9–26.7% of damaged logs and 2.36–3.25 holes/log. Eight cerambycid species were reared: viz. Acalolepta vitalisi (Pic, 1925) and Coptops annulipes (Gahan, 1894) from Acacia hybrid and A. mangium; Batocera lineolata (Chevrolat, 1852) and Blepephaeus fulvus (Pic, 1933) from Eucalyptus hybrid and E. urophylla; Cephalallus unicolor (Gahan, 1906) and Monochamus alternatus (Hope, 1843) from Pinus caribaea and P. massoniana; Stromatium longicorne (Newman, 1842) and Tapinolachnus lacordairei (Thomson, 1864) from Chukrasia tabularis. Most of these trees are new hosts or even the first known host for these cerambycids. The results suggest that the transport of harvested woods may contribute to the dispersal of longhorn beetles to new locations.
