“…For this reason, several projects were conducted for the eradication of invasive alien species in Europe, as they are recognized to cause heavy impacts on native biodiversity Shine et al, 2009) and for the protection of native species and habitats in the Archipelago (http://www.montecristo2010.it, http:// www.restoconlife.eu/). Nematodes with other organisms present in the soil can be accidentally introduced via a range of human-associated pathways (Meagher, 1977;Hulme et al, 2008;Hughes et al, 2010), in particular as contaminant of traded plant propagation material (Davidson et al, 2005; McNeill et al, 2006) and through clothing and footwear (Baker, 1966;Davidson et al, 2005;Webber and Rose, 2008).Unfortunately, there is still a considerable lack of knowledge about the incidence and distribution of terrestrial nematodes (new species are continuously described, such as Oscheius onirici Torrini et al, 2015) and their status as alien or endemic. The only data concerning some heavy and famous pests of agriculture (e.g., Globodera spp.)…”

Montecristo Island is an integral natural reserve of the Tuscan Archipelago National Park (Central Italy), characterized by a peculiar assemblage of flora and fauna, with several endemic taxa, and also with a high number of alien species. During a soil survey, we found an alien Oscheius tipulae Lam & Webster, 1971 isolate, phylogenetically close to others from South America. In this article, we examined the possible pathways of introduction of this nematode. Because of the high number of alien plants in this protected area and the low desiccation survival ability of O. tipulae, we hypothesized that the presence of this alien nematode isolate may be related to the soil of introduced plants, although historical association with plant-associated invertebrates is also possible. Further studies with more populations and marker molecules are necessary to investigate the distribution of O. tipulae and the possible impact on this natural reserve.Key words: alien nematode isolate, Central Italy, desiccation assay, genetics, nematode introduction.Insular biodiversity is characterized by a peculiar fauna and flora, with high levels of endemism (Whittaker and Fern andez-Palacios, 2007). The Tuscan Archipelago consists of seven major and several minor islands located between Corsica and Tuscan coast. Most of the islands of the Tuscan Archipelago are included, partly or entirely, in the Tuscan Archipelago National Park, established in 1999, while Montecristo Island has been a state natural reserve since 1971. Montecristo Island is one of the most peculiar ones, because it is a biogenetic reserve established in 1971 by a ministerial decree to protect its unique nature. Visitors face many restrictions and this management strategy helped the preservation of a peculiar combination of flora and fauna (http://www.corpoforestale. it). Notwithstanding the rigorous protection, several alien species, both animals and plants, are present in this island, mainly as historical-cultural legacies (http:// www.montecristo2010.it, http://www.restoconlife.eu/).Despite the importance of these islands and the presence of several protected areas, comprehensive projects are currently carried out only for some taxonomic groups (AA. VV., 1976;Cianferoni et al., 2013). Data on nematodes of the Tuscan Archipelago National Park are almost absent. The only available concern is endoparasites, e.g., stomach nematodes of goats, Capra hircus Linnaeus, 1758 (Lucchesi et al., 2011). For this reason, we began a survey of nematodes to fill the gap of the knowledge on these taxa.During a soil survey in Montecristo Island, we found an alien O. tipulae strain, phylogenetically close to the South American ones. Alien species (Scalera and Zaghi, 2004) are present in this area and in the other islands of the Tuscan Archipelago National Park (Mazza et al., 2012;Inghilesi et al., 2013a;Lazzaro et al., 2014). For this reason, several projects were conducted for the eradication of invasive alien species in Europe, as they are recognized to cause heavy impacts o...

“…The presently studied population of this species was in association with galleries on bark samples of Pinus eldarica trees in the Lavizan region, Tehran.

Due to importance and effectiveness of some entomopathogenic or insect parasitic nematodes in controlling of agricultural pests, or pests of non-agricultural plants, a study was conducted in order to identify the species of this group of nematodes in city of Tehran. As the result, three species belonging to the genus Oscheius were recovered in association with bark samples having the bark beetle galleries. Morphological and molecular data were provided for two recently recovered species of the genus, namely O. necromenus and O. onirici. Molecular data were also provided for a recently recovered isolate of O. tipulae. All three species were recovered in association with bark samples collected from dead trees in the city of Tehran. Morphological characters and morphometric data of the two aforementioned species are in accordance with the data given in their original descriptions. One recovered individual from a small bark sample characterized by its short body length was sequenced for its 28S and internal transcribed spacer (ITS) rDNA loci, and the results of BLAST search using the newly obtained partial sequences revealed that it belonged to O. tipulae. Molecular phylogenetic studies revealed recently sequenced Iranian populations of O. onirici and O. tipulae forming a clade with other isolates/populations of these species in ITS tree with maximal Bayesian posterior probability (BPP), and presently sequenced isolates of O. tipulae and O. necromenus form a clade with other isolates of these species in 28S tree. The two species O. onirici and O. necromenus were reported in Iran for the first time.

“…Several EPN species, all symbiotic with bacterial strains of Serratia, have been found in the Heterorhabditidoides group (Heterorhabditidoides (=Oscheius) chongmingensis and H. rugaoensis) and the insectivora group (Oscheius carolinensis) (Zhang et al, 2008;Ye et al, 2010;Liu et al, 2012). Other Oscheius species are parasitic to insects, some of them also commonly associated with Serratia (Lephoto et al, 2015;Torrini et al, 2015), although their entomopathogenicity has yet to be examined according to the criteria of EPNs revised by Dillman et al (2012).…”

A new species, Oscheius microvilli n. sp., was found on Chongming Island (Shanghai, China). The new species is morphologically similar to the type strain of Oscheius myriophilus, but can be distinguished from it and other species of Oscheius on the basis of unique morphological characteristics of the bursa as well as male papillae. In this new species, the male bursal papillar formula is 2, 1, 3, 3 with everted tips in the first, fifth, and seventh pairs. The bursal rim is jagged, joins together anterior to the spicules, and is partially extended and decorated with microvilli. The spicules are incompletely separated, and the tail does not extend beyond the bursa. Phylogenetic trees of 18S rDNA and internal transcribed spacer indicate that the new species belongs to the insectivora group of the genus Oscheius; it is most closely related to O. myriophilus, and the two species can be distinguished on the basis of their different body length, morphological features of the bursa, and molecular data. The new species is facultatively associated with a bacterial strain of Serratia. The LC 50 of this novel nematode against Galleria mellonella was 69.1 dauer juveniles per milliliter after 48 hr of infection.
