Abstract

Liparthrum colchicumSemenov (Coleoptera Curculionidae Scolytinae) is a relatively unknown monophagous insect species primarily associated with thin dried twigs (about 0.5-1cm in diameter) of Laurel (Laurus nobilis). After being caught in traps located at Italian ports, it was initially considered an intercepted species alien to the country. However, recent findings, suggest that this beetle may have a different origin. Several records from different sites of Tuscany and Latium showed that it could be relatively widespread in Italy. These observations strengthened the hypothesis that this scolytid, harmless to L. nobilis, might be already established or even native to the country. Therefore, we argue that it could have been easily overlooked thus far, as it thrives only in twigs already wilted due to different environmental factors. Moreover, field observations, carried out in the two Italian Regions, evidenced high frequencies of its infestations in Laurel twigs previously colonized by Xylosandrus compactus. Notes on the taxonomy and biology of this species are also reported in the present wo

意大利的紫茧蜂:引种、建立种还是本地种?

月桂(Laurus nobilis)的细干枝(直径约0.5 ~ 1cm)是一种鲜为人知的单食性昆虫。在被意大利港口的陷阱捕获后，它最初被认为是一种被截获的外来物种。然而，最近的发现表明，这种甲虫可能有不同的起源。来自托斯卡纳和拉提姆不同地点的一些记录表明，它在意大利可能相对普遍。这些观察结果加强了这样一种假设，即这种对大菱鲆无害的柱头虫可能已经存在，甚至可能原产于这个国家。因此，我们认为到目前为止，它可能很容易被忽视，因为它只在由于不同的环境因素而已经枯萎的树枝上茁壮成长。此外，在意大利两个地区进行的实地观察表明，它在以前由紧凑木沙鼠殖民的月桂枝上的侵染频率很高。本文还报道了本种的分类学和生物学情况
