Investigation of the global transportation of Culicoides biting midges, vectors of livestock and equid arboviruses, from flower‐packing plants in Kenya

Medical and Veterinary Entomology, EarlyView.
Arboviral diseases spread by Culicoides biting midges have been introduced into Europe by unknown means. A possible route is the carriage of midges with cut flowers shipped to flower markets. We sampled Culicoides in and around a cut flower farm in Kenya; midges were caught in the vicinity and a greenhouse, but not where flowers are processed.
