Lyctus brunneus (Stephens) ( Fig. 9C )

Xylotrogus brunneus Stephens, 1830: 117 .

Distribution in mainland China: AH, FJ, GD, GX, GZ, HA, HE, HN, JS, JX, SC, SN, YN ( Hua 2002).

Other distribution. Cosmopolitan but has mainly been found in arid and tropical areas. It may have a Holarctic origin, but has now invaded most faunal regions ( Liu & Geis 2019).

Biology. As the most important pest of artificial wooden and bamboo structures, this species in particular attacks dried wood, furniture and construction timbers, and has dispersed all over the world through trade in timber and wood products. It is clearly polyphagous ( Beeson & Bhatia 1937; Liu & Geis 2019). The larvae are attacked by various parasitoid (Hym: Braconidae ) and predaceous insects (Col: Cleridae ), but not in high enough numbers to ensure efficient biological control ( Liu et al. 2016).
