Ambrosiodmus rubricollis
Beaver and Browne, 1978: Not host selective, bust usually attacking stems of less than 15 cm diameter. Browne, 1961: This species, which is found in Japan, is the smallest Malayan representative of the group, and also the most common, although it is not abundant. It has been found infesting dead saplings and cut poles of diameter varying from 2 - 15 cm. It appears that this species is not host selective. Wood, 2007: Boring in wood of limbs larger than 5 cm in diameter and stumps to 30 cm in diameter. Beaver and Liu, 2010: It usually attacks stems from about 2-15 cm diameter (Browne 1961). The species is known to have preoral mycangia at the base of the mandibles (Takagi 1967). Wood, 1982: The American series were taken from boles and stumps of trees. Kirkendall and Faccoli, 2010: This species is native to east Asia and is now also established in eastern North America and Australia. It can now be found in the temperate zone of Europe. This species is xylomycetophagous and is a polyphagous feeder. The hosts for this species are broadleaf trees. Rabaglia et al. 2006: This Asian species was first found in Maryland (Bright 1968) and is now commonly found in the mid-Atlantic and southeastern states.
