    A list of scale insects (Hemiptera: Coccoidea) intercepted on imported succulent plants at the plant quarantine of Korea from 2006 to 2010 is provided. A total of 15 species belonging to four families are listed. Of the 15 species that were intercepted, some species are potential pests that could gain entry and establish in Korea through the importation of plant material. Current information on intercepted scale insects is required to alert inspectors at quarantine sites to look carefully at succulent plants to prevent the introduction of an exotic species

    First incursion of the Asian root mealybug Ripersiella planetica in Europe (Hemiptera, Coccoidea, Rhizoecidae)

    The Rhizoecidae is a family of the Coccoidea (hodGSon, 2012) containing 233 species worldwide that are hypogaeic and parasitic on plant roots, hence their common name ‚Äėroot mealybugs‚Äô (Koz√°r & Konczn√© BEnEdicty, 2007). Several species are economically important plant pests and Ripersiella hibisci (Kawai & Takagi, 1971) is a regulated quarantine pest in the European Union (mAlumPhy & roBinSon, 2004). The Asian root mealybug Ripersiella planetica (Williams, 2004) has been found recently in Malta.peer-reviewe

    Invasive mealybugs (Hemiptera: Pseudococcidae) and the threats they present to Mediterranean countries

    Get PDF
    Due to their small size and cryptic habits, alien mealybugs (Insecta: Hemiptera: Pseudococcidae) can easily enter countries around the Mediterranean basin through trade in live planting material and fresh produce. The recent increase in mealybug introductions probably reflects ever-faster transport in globalised trade, the free movement of goods within the European Union and the weakness of plant quarantine screening by national plant protection organisations. Purchases over the Internet, shipments of plants by post and exchanges of material by plant hobbyists escape control by quarantine services and contribute substantially to mealybug introductions on plants like bamboos and succulents.peer-reviewe
