Some of the trees which it can damage are forest and woodland species. Asian longhorn beetle is not known to be present in the United Kingdom, although one outbreak of a breeding population was found in Paddock Wood, Kent, England, in It was subject to rapid eradication action, and annual surveys since then have found no evidence of a continuing presence. There have also been occasional interceptions of individual beetles in the UK.

CISR: Asian Long-Horned Beetle
Retracing introduction routes is crucial for understanding the evolutionary processes involved in an invasion, as well as for highlighting the invasion history of a species at the global scale. It is responsible for severe losses of urban trees, in both its native and invaded ranges. Based on historical and genetic data, several hypotheses have been formulated concerning its invasion history, including the possibility of multiple introductions from the native zone and secondary dispersal within the invaded areas, but none have been formally tested. In this study, we characterized the genetic structure of ALB in both its native and invaded ranges using microsatellites. In order to test different invasion scenarios, we used an approximate Bayesian "random forest" algorithm together with traditional population genetics approaches.
Search for:. The Situation: An exotic long-horned beetle was first discovered attacking ornamental trees in New York City and Chicago. Detections of this pest have since been made in most states in the northeastern portion of the United States as well as in California beginning in Their route of entry into the USA appears to have been in untreated wooden packing crates originating in China. These beetles are large, conspicuous insects, readily recognized by their horns or antennae.
Despite the buzz in recent years about other invasive insects that pose an even larger threat to agriculture and trees—such as the spotted lanternfly, the stink bug and the emerald ash borer—Penn State researchers have continued to study another damaging pest, the Asian longhorned beetle. Their most recent research revealed that the larval offspring of the wood-borer native to China can feed and thrive on tree species whose tissues would sicken their parents, perhaps explaining how the beetle expands its range, even when its preferred host trees—maples, elms and willows—are not nearby. The researchers' attention on Asian longhorned beetles remains well-placed because the U. And eradication efforts continue in New York, Massachusetts and Ohio. The Asian longhorned beetle most likely came to the United States inside wood packaging material from Asia in the early s, according to Kelli Hoover, professor of entomology.
