The longhorn beetle, Stromatium longicorne (Coleoptera: Cerambycidae): Report and damage on a wooden facility in Sumatra, Indonesia

Abstract

Stromatium longicorne (Newman, 1842) (Coleoptera: Cerambycidae) is an economically important longhorn beetle because of its extremely polyphagous nature, high dispersal, and adaptation capacity to different environments. The objective of this study was to report the presence of S. longicorne, for the first time, in Sumatra, Indonesia. We also described the damage on wooden timber doors in a facility in Sumatra. Around 10 adults of S. longicorne were seen moving through holes on two wooden timber doors (210 cm high × 90 cm long × 3 cm wide) in April 2018 in Pangkalan Kerinci, Riau, Sumatra. The number and diameter (cm) of holes made by the beetles per door were evaluated at the end of the adult beetle outbreak. A total of 19 and 34 holes was made per wooden door. The diameter of holes ranged 0.88–1.01 cm. The damaged doors must be replaced by glass doors or doors made using a harder wood.
