130. Xylosandrus germanus (Blandford)

Xyleborus germanus Blandford, 1894a: 106 .

Distribution: China (CE, NO, SE, SW, WP), Japan, Korea, Taiwan, Vietnam. The species also occurs in Thailand (RAB, unpublished records). Imported and established in Western Europe and North America. [2] Hosts: Strongly polyphagous. Weber and McPherson (1983a) list more than 200 species in over 50 families.

Biology: The biology is described by Weber and McPherson (1983b). Nakashima et al. (1992) characterise the ambrosia fungi. It occasionally attacks healthy and newly transplanted trees and shrubs ( Rabaglia et al. 2006). Peer & Taborsky (2004, 2005) have studied male dispersal, variations in sex ratio, and outbreeding depression in the species. Ito et al. (2008) discuss the genetic structure of Japanese populations. Biedermann et al. (2009) describe a laboratory breeding technique.
