Cnestus mutilatus (Blandford) : Dole & Cognato, 2010: 530.

Thai distribution: N: Chiang Mai ( Schedl 1971 as Xyleborus mutilatus ). No later records from Thailand.

Other distribution: Throughout the Oriental region from India to Indonesia and New Guinea, extending North to China, Japan, Korea, Taiwan. Introduced to and invasive in southern U.S.A. ( Haack 2006, Rabaglia et al. 2006). (4)

Biology: The biology of the species has been studied in Japan by Kajimura and Hijii (1992, 1994), in China by Tang (2000), and in U.S.A. by Stone and colleagues (Stone & Nebeker 2007, Stone et al. 2007). The associated ambrosia fungus has been described by Six et al. (2009). It is a pest of young Castanea mollissima (Fagaceae) trees in China (Zhejiang) ( Tang 2000), but in USA appears to favour stressed host plants (Stone et al. 2007).
