Abstract

The "passion fruit woodiness" (PFW) is the most important viral disease of the passion fruit crops around the world, including Brazil where significant losses have been observed in the main producing regions. This disease does not discriminate the systems of production, and its high incidence has become the culture, originally semi-perennial, in annual, leading producers to migrate to new regions or abandon the crop. Initially, the viral isolates associated to PFW were identified by serological and biological approaches such as Passion fruit woodiness virus (PWV). However, in recent years, two other Potyvirus were also identified to be associated with this disease: Cowpea aphid-borne mosaic virus (CABMV), in Africa and Brazil, and East Asian passiflora virus (AEFV), restricted to Japan. The non-availability resistance to the viruses associated with the PFW raises the possibility of developing crop management tactics, such as: cultivation of tolerant varieties; different levels of fertilization of the seedlings before being taken into the field; escape of the periods of the highest population of the aphid vectors; and control of weeds, mainly Fabaceae. This project aims to: (i) do a survey to identify and characterize CABMV isolates from the main producing regions of São Paulo state; (ii) evaluate temporal and spatial distribution of aphids species associated with passion fruit crop, and which have potential to act as vectors; (iii) evaluate the behavior of passion fruit seedlings with different levels of nutrient, infected with CABMV; (iv) conduct a survey of weeds associated with passion fruit crop and challenge species of Fabaceae that can act as reservoir of CABMV. We will also evaluate the interference of the CABMV on phytochemical composition of two major classes of secondary metabolites referred as active ingredients: flavonoids and alkaloids. (AU)
