Pest categorisation of Diabrotica undecimpunctata howardi.

ABSTRACT: The EFSA Panel on Plant Health performed a pest categorisation of Diabrotica undecimpunctata howardi (Coleoptera: Chrysomelidae) for the EU. This subspecies occurs in North and Central America. Adults oviposit on annual plants in the families Asteraceae, Chenopodiaceae, Cucurbitaceae, Fabaceae, Poaceae, Polygonaceae and Solanaceae. Adults feed on tender plant parts in hosts in 40 additional botanical families. Preimaginal development takes place on the roots of the host plant, where larvae feed and pupate. D. undecimpunctata howardi is a multivoltine species. Overwintering adults, which may enter a facultative diapause, abandon crops in autumn and reinvade them in spring. D. undecimpunctata howardi is not known to occur in the EU and is regulated in Annex IIA of Commis
