oa Journal of the Entomological Society of Southern Africa - Isolations of Middelburg virus from Aedes (Ochlerotatus) juppi McIntosh (Diptera: Culicidae) suggestive of a reservoir vector



Seventeen alphavirus isolates (16 Middelburg and 1 Sindbis) were obtained from 3957 Aedes Juppi mosquitoes collected at a single site on a farm at Tweespruit in the south-western Orange Free State Highveld. Collections were thought to be the first brood of the season and the appearance of Middelburg virus due to the presence of transovarially infected mosquitoes. This could indicate that Ae. juppi serves as a reservoir vector to carry this virus through dry inter-epizootic periods.
