This study undertakes to unravel vector transmission biology
of Sweet potato mild mottle virus (SPMMV), a type member
of the genus Ipomovirus in the family Potyviridae. This study
will be conducted in four selected districts of Uganda for two
sweetpotato growing seasons of 2012 and 2013. The districts
include Masaka and Mpigi (around Lake Victoria basin in
Central region); and Mbale and Soroti (Eastern region).
Sweetpotato is the second most important root crop in East
Africa, but production there is greatly constrained by viruses
including SPMMV, a critical component of the devastating
sweet potato virus disease (SPVD) complex. While the vectors
disseminating other common viruses of sweetpotato in East
Africa are well known, the vector transmitting SPMMV has
remained cryptic. Consequently, the epidemiological relationship
between incidence of SPMMV and its potential vectors in the
fields is unknown. The vector transmitting SPMMV in
sweetpotato and the SPMMV-vector epidemiological relations
under field conditions will be determined. Farmer awareness
of SPVD complex effects of sweetpotato yield will be enhanced
through field activities involving farmers.
