147. Xyleborus cognatus Blandford

Xyleborus cognatus Blandford, 1896b: 19 .

Thai distribution: S: Ranong (Murphy & Meepol 1990). No more recent records from Thailand.

Other distribution: From India and Sri Lanka through Southeast Asia and Indonesia to New Guinea and the Pacific islands. Intercepted in Japan in timber imported from the region. (4)

Biology: Polyphagous (Beeson 1930, Browne 1961 a, Ohno 1990). The species is frequently associated with mangrove forests, but also attacks a very wide variety of other trees (Browne 1961 a, Maiti & Saha 2004). Beeson (1930) describes the gallery system, and considers the species to be one of the most injurious in the Andaman Is. In Thailand, Murphy and Meepol (1990) plot the numbers caught in light traps over nine months, and relate the changes to rainfall.
