    Abstract:
    The EFSA Panel on Plant Health performed a pest categorisation of the beetle Diabrotica undecimpunctata undecimpunctata (Coleoptera: Chrysomelidae) for the EU. This species occurs in western USA and Mexico. Adults oviposit on annual plants in the families Chenopodiaceae, Cucurbitaceae, Fabaceae, Poaceae, Polygonaceae and Solanaceae. Adults feed on tender plant parts in hosts in 30 additional botanical families. Preimaginal development takes place on the roots of the host plant, where larvae feed and pupate. The insect completes one to three generations per year depending on temperature. Overwintering adults (no diapause) may abandon crops to seek shelter in wild vegetation and reinvade crops in spring. D. undecimpunctata undecimpunctata is not known to occur in the EU and is regulated in Annex IIA of Commission Implementing Regulation 2019/2072. This species is a competent vector of squash mosaic virus, a pathogen already present and not regulated in the EU. Within Commission Implementing Regulation 2019/2072, potential entry pathways for D. undecimpunctata undecimpunctata, such as Poaceae and Solanaceae plants for planting with foliage and soil/growing medium, and soil/growing media by themselves can be considered as closed. However, plants for planting of the families Chenopodiaceae, Cucurbitaceae, Fabaceae and Polygonaceae are not specifically regulated. Should D. undecimpunctata undecimpunctata arrive in the EU, climatic conditions and availability of susceptible hosts provide conditions suitable for establishment and further spread. Economic impact is anticipated. D. undecimpunctata undecimpunctata satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest. This species does not meet the criteria of being present in the EU nor plants for planting being the main pathway for spread for it to be regarded as a potential regulated non-quarantine pest.
