Vector-virus-host interactions vary with the mode of virus transmission, and often persistent viruses provide fitness benefits to vectors so as to benefit their own spread. However this hypothesis (vector-manipulation hypothesis) is based on the assumption of host plant susceptibility to infecting viruses. This presentation would involve two pathosystems with persistent viruses and two vectors (sweetpotato. whitefly and thrips).

Pathosystem 1; Sweetpotato whitefly-tomato yellow leaf curl virus-tomato
Pathosystem 2: Tobacco thrips-tomato spotted wilt orthotospovirus- peanut

This presentation will focus on how virus-resistant genotypes of tomato and peanut influence virus-host interactions, and how these interactions in turn modulate host-vector and virus-vector interctions. This presentation will also assess how the resulting component interactions align with the perceived assumptions of vector-manipulation hypothesis.
