Xyleborus glabratus Eichhoff, 1877: 127 .

Thai distribution: N: Chiang Mai; N-E: Nakhon Ratchasima. New to Thailand .

New records: Chiang Mai, Doi Pui, Chang Khian Highland Res. Stn, ex avocado log, 21.iv.2013 (S. Buranaphanichpan) (1); Nakhon Ratchasima, Khao Yai NP, Dong Ngu How area , 14° 28.524' N, 101° 22.928' E, 757 m, MT, 26.xii.2006 – 2.i.2007 (W. Sook-kho) (1) .

Other distribution: Bangladesh, China (Fujian, Hunan, Sichuan), India (Assam, W. Bengal), Japan, Taiwan. Imported to and established in Eastern U.S.A. (2)

Biology: The species has an evident preference for the family Lauraceae , and its attacks are apparently restricted to that family in the U.S.A. ( Rabaglia et al. 2006, Fraedrich et al. 2008). In the Oriental region, it has also been recorded on three occasions from other families ( Dipterocarpaceae , Fagaceae, Leguminosae ) ( Beaver & Liu 2010), but it is not clear whether it was breeding in these trees. Although not of economic importance in its native range, the species is an invasive pest in the U.S.A., where it transmits a pathogenic fungus ( Raffaelea lauricola ) to a variety of Lauraceae trees (including avocado) ( Harrington et al. 2011). Consequently its host preferences, attractant volatiles, flight activity and other aspects of its biology, and possible management and control methods, have recently been studied intensively (e.g. Hanula et al. 2008, Koch & Smith 2008, Hulcr et al. 2011, Brar et al. 2012, 2013, Kendra et al. 2012, Formby et al. 2013, Maner et al. 2013, Mayfield et al. 2013).
