    Halyomorpha halys (Hemiptera, Pentatomidae): ten years after in Europe

    Get PDF
    We describe the situation of the invasion of Halyomorpha halys (HH) in Europe, since its discovery in Switzerland in 2007, but with effective presence since 2004. After a relative stagnation for many years, the dispersal of H. halys seems to increase, probably due to growing populations and passive transport by human activities. We suppose that it is not possible to stop the invasion of this species in Europe due to global warming but mostly to ecological characteristics such as high dispersal capability especially with human assistance , a broad host spectrum, a high female fecundity, and a high overwintering survival. The particularly mild winter 2013-2014 in France and Western Europe may further contribute to its progressive dispersal. It is likely that H. halys is already much wider distributed than previously assumed because it is easily confused with the native species, Raphigaster nebulosa. Most recently H. halys was recorded from Hungary, which is nearly 1,000 km east of its centre of distribution in Switzerland. In France, H. halys was first recorded in the Alsace in 2012, but in fall 2013 it was also discovered 400 km further west in Paris and Ile de France. The ongoing dispersal in western France will be monitored and prevention methods will be investigated. After the first occurrence in 2012, a “citizen-science” type of survey allowed to detect many specimens of H. halys in different areas of Northern Italy, with a bigger nucleus centred in the territory of first detection, in the Emilia Romagna region. As this region has extended areas cultivated with high value fruit crops, field monitoring is currently being performed to verify H. halys presence and damage

    El raro chinche de las marismas Teratocoris antennatus (Boheman, 1852) (Hemiptera, Miridae), nueva especie para Portugal

    Ria de Aveiro costal lagoon is a socio-ecological system framed between the land and the sea. The lagoon is embedded in a biodiversity rich landscape mosaic comprising beaches, dunes, sandflats, mudflats, seagrasses, and small water channels, and is one of the largest saltmarsh areas in Portugal and in Europe, supporting coastal food webs and providing nursery areas for several species. Despite being a Long-Term Ecological Research (LTER) site and integrating the Natura 2000 network, few systematic studies have been carried on its entomofauna. In this work, field collections were carried in seven locations along Ria de Aveiro saltmarsh areas by sweep-netting the dominating halophyte vegetation in September 2020. From these collections, Teratocoris antennatus (Boheman, 1852), a rare marsh bug, is reported for the first time for Portugal

    New data about the distribution of Reduvius carinatus Reuter, 1892 (Heteroptera, Reduviidae) in Spain

    Abstract. New data are provided about the distribution of Reduvius carinatus Reuter, 1892 in Spain, which is the only European country where it is known. In Europe, the species was reported the first time in the province of AlmerĂ­a (Ribes, 1986) but the record was forgotten or considered doubtful in some posterior papers. Recently two specimens have been photographed in Ciudad Real, which identification has been verified comparing them to the specimen from AlmerĂ­a of Jordi Ribes collection (Barcelona)

    Halyomorpha halys StĂĄl 1855, trovata per la prima volta nelle Alpi centrali italiane (Insecta: Heteroptera: Pentatomidae).

    First record in Italian Central Alps of Halyomorpha halys (Insecta: Heteroptera: Pentatomidae). The Brown Marmorated Stink Bug was detected for the first time in Italian Central Alps in September 2014, in at Colico, province of Lecco (Northern Italy). Native to east Asia, and introduced in North America and Central Europe, it has a wide host range and an extremely high potential as an invasive pest of many fruit, horticultural and ornamentals crops. From the results of a citizen science type of survey, it emerged that H. halys is quite widely distributed in the Italian regions of Emilia Romagna, Lombardy, Liguria, Piemonte and Friuli: especially in lowlands and hilly areas of the plains and hills, but not on the Alps themselves

    First Results on Heteroptera (Hemiptera) of Dry Grassland in Malpaga-Basella Nature Reserve (Italy)

    The Nature Reserve Malpaga-Basella, located along the Serio River in Lombardy, was recently established in 2017. It is interesting as it presents plant species typical in dry grassland habitats, not present in the surrounding area. In this study, Heteroptera were surveyed in the Nature Reserve and in a bordering giant Miscanthus crop in 2019. The biodiversity of the reserve was well characterized by the presence of species linked to arid environments with steppe or Mediterranean characteristics, like Antheminia lunulata. Four species new for Lombardy were collected, Lygus italicus, Drymus pilipes, Ortholomus punctipennis, and Arenocoris waltlii. Giant Miscanthus hosted only a few ubiquitous species, also collected in the Nature Reserve
