“…With a few exceptions (Hulcr and Cognato 2013;Beaver et al 2014), the scolytine fauna of southeast Asia and China are poorly known and contain numerous undescribed species (A. Cognato, personal observation). Increased study of the diversity of this fauna is necessary given the large numbers of specimens intercepted at US ports (Haack and Rabaglia 2013).…”

“…Despite these efforts, the taxonomy of the tribe remains problematic due to its large diversity of more than 1,168 species . The overwhelming majority of species have been described/placed in Xyleborus Eichhoff, how-ever, many species have been transferred to other genera in recent publications (Hulcr and Cognato 2013;Beaver et al 2014). Ambrosiophilus is one of the most recently described xyleborine genera and is native to the Oriental and Oceanic regions.…”

A checklist of Cyclorhipidion and Xyleborus species from these regions and all Ambrosiophilus and Ambrosiodmus species was created.…”

T he species of Scolytinae subfamily have a worldwide distribution, and are found mainly in the Neo-tropic regions. They usually dominate the communities of wood borer insects. The aim of the present study was to determine the diversity among Scolytinae species associated with balsa, teak, rubber and gamhar plantations located in the humid tropical zone of the Ecuadorian littoral. In each plantation seven flight interception traps containing an ethanol / gel mixture were installed, with a collection frequency of 15 days for three months in the dry period. A total of 1437 specimens were collected, represented by Xyleborini, Cryphalini, Corthylini and Ipini tribes. In the four plantations, 18 species of Scolitids were collected, of which 16 were recorded in the balsa plantation, while in the other plantations 10 to 12 species were found. The most abundant Scolitids were Hypothenemus spp., Corthylus spp., Xyleborus affinis, Xyleborinus bicornatulus and Premnobium cavipennis. The Shannon-Wiener diversity index was higher in the balsa culture (H'= 2.37) and lower in Teak (H'= 1.57). The Jaccard similarity index was higher among the teak and rubber plantations (Cj = 0.9090) while the balsa plantation obtained less similarity with respect to the other three plantations. The greatest diversity of Scolitids was recorded in the balsa plantation, which is a native species, unlike the other forest species, which are exotic, indicating that the diversity would be influenced by the host tree and the location where they are found.Key words: Scolitids, diversity, balsa, teak, Ecuador, gamhar, rubber. ResumenL as especies de la subfamilia Scolytinae tienen una distribución global, abundan principalmente en el Neo trópico y dominan usualmente las comunidades de insectos barrenadores de la madera. El objetivo del presente estudio fue determinar la diversidad de las especies Scolytinae asociadas a plantaciones de balsa, teca, caucho y melina, en la zona tropical húmeda del litoral ecuatoriano. En cada plantación se instalaron siete trampas de interceptación de vuelo conteniendo una mezcla de etanol/gel, con una frecuencia de recolección de 15 días durante tres meses en el periodo seco. En total se recolectaron 1437 especímenes, representados por las tribus Xyleborini, Cryphalini, Corthylini e Ipini. En las cuatro plantaciones se colectaron 18 especies de escolítinos, de las cuales, 16 se registraron en la plantación de balsa, mientras que en las otras plantaciones se encontraron entre 10 y 12 especies. Los escolítinos con mayor abundancia fueron Hypothenemus spp., Corthylus spp., Xyleborus affinis, Xyleborinus bicornatulus y Premnobium cavipennis. El índice de diversidad de Shannon-Wiener fue mayor en el cultivo de balsa (H´=2.37) y menor en teca (H´= 1.57). El índice de similitud de Jaccard fue mayor entre las plantaciones de teca y caucho (Cj= 0,9090) mientras que la balsa obtuvo menor similitud con respecto a las tres plantaciones.

A first inference of the phylogeography of the worldwide invader Xylosandrus compactus

Native to Southeastern Asia, the ambrosia beetle Xylosandrus compactus is invasive worldwide. Its invasion is favoured by its cryptic lifestyle, symbiosis with a fungus that facilitates a broad range of host plants, and predominant sib-mating reproduction. X. compactus invaded Africa more than a century ago and the Americas and Pacific Islands in the middle of the twentieth century. It was not detected in Europe before 2011, when it was first reported in Italy before quickly spreading to France, Greece and Spain. Despite the negative environmental, agricultural and economic consequences of the invasion of X. compactus, its invasion history and main pathways remain poorly documented. We used COI and RAD sequencing to (i) characterise the worldwide genetic structure of the species, (ii) disentangle the origin(s) of the non-native populations on the three invaded continents and (iii) analyse the genetic diversity and pathways within each invaded region. Three mitochondrial lineages were identified in the native range. Populations invading Europe and the American-Pacific region originated from the first lineage and were only slightly genetically differentiated at nuclear SNP markers, suggesting independent introductions from close sources in or near Shanghai, ca. 60 years apart. Populations invading Africa originated from the second lineage, likely from India or Vietnam.
