Pine wilt disease is one of the most serious introduced threats to coniferous forests worldwide. Its causal agent, the pinewood nematode (PWN), Bursaphelenchus xylophilus, is vectored primarily by cerambycids of the genus Monochamus Dejean throughout its native (North America) and introduced (Japan, China, Korea, Taiwan, Portugal) ranges. Despite strict import regulations and phytosanitary measures, interception records indicate that PWN and Monochamus species continue to be moved worldwide. Following its introduction in Portugal in the late 1990s, extensive monitoring programs for PWN and its vectors have been conducted throughout the European Union, using locally developed and tested lures and traps. The trapping system developed in Europe and used in this study is composed of a Crosstrap ® and Galloprotect Pack ® lures. These trapping systems were deployed in two locations in the USA, two locations in Canada, and one location in China in order to test their capacity to detect Monochamus species exotic to Europe. Large numbers of M. carolinensis, M. mutator, M. notatus, M. s. scutellatus, M. clamator, and M. titillator were trapped in North America, while large numbers of M. alternatus were trapped in China. The trapping systems developed in Europe for monitoring the European Monochamus species are also effective for the detection of many exotic Monochamus species and could thus be used as an early detection tool in ports and other high-risk sites.
Plain Language Summary
Pine wilt disease is a serious threat to forests in Europe and Asia and its causal agent, the pinewood nematode, is vectored by longhorn beetles in the genus Monochamus, native to North America. We tested a trap and lure in the USA and Canada to determine how well it detected North American Monochamus species in the event that these beetles were accidentally introduced to Europe in wood used to pack imported goods. The trap system successfully detected large numbers of six different species of Monochamus and would thus be highly useful as an early detection tool in ports and other high-risk sites in Europe.
