A single female can found a new population, and she does not have to be fertilized. \u00a0She can produce sons from unfertilized eggs and mate with them.\u00a0 Movement of infested firewood would achieve rapid, long-distance dispersal.\u00a0 In addition, <em>X. pfeilii<\/em> flies (specimens have been caught with funnel traps) (Humble, 2001; Mudge et al., 2001).\u00a0 Therefore, it receives a <strong><span style=\"color: #008000;\">High (3)<\/span><\/strong> in this category.<\/p>\n<p style=\"padding-left: 30px;\">\u2013 Low (1) does not have high reproductive or dispersal potential.<\/p>\n<p style=\"padding-left: 30px;\">\u2013 Medium (2) has either high reproductive or dispersal potential.<\/p>\n<p style=\"padding-left: 30px;\"><strong>\u2013 High (3) has both high reproduction and dispersal potential.<\/strong><\/p>\n<p><strong>4) Economic Impact:<\/strong> <em>Xyleborus pfeilii<\/em> does not appear to have any recognized economic impact, even though it was introduced to much of Europe and has been present there for almost 200 years.\u00a0 There is some doubt that economically-important trees in California would be significantly impacted, considering that most such trees are probably members of genera well-represented in Europe, and this beetle is apparently not a significant pest there.\u00a0 There is the chance that it could vector a plant-pathogenic fungus to economically-important trees.\u00a0 Therefore, it receives a <strong><span style=\"color: #008000;\">Low (1<\/span><\/strong>) in this category.<\/p>\n<p><strong>Economic Impact:\u00a0 <span style=\"color: #008000;\">E<\/span><\/strong><\/p>\n<p style=\"padding-left: 30px;\">A.
