“…This virus is transmitted by aphids and grafting, and mechanically during cultural practices that injure the plants, but not by seeds (Fischer & Rezende, 2008). The virus also does not appear to be transmitted mechanically during hand‐pollination operations (Spadotti et al., 2021).…”

Passionfruit severe leaf distortion virus (PSLDV) is a begomovirus transmitted by Bemisia tabaci Middle East‐Asia Minor 1 (MEAM1), associated with severe disease in passion flowers. This study aimed to evaluate the reaction of plants of different species of Passiflora to infection with PSLDV, expand the known host range of the virus and determine the minimum virus acquisition and inoculation access periods and the time of virus retention by B. tabaci MEAM1. Plants of Passiflora cincinnata, P. mucronata and P. malacophylla were not infected with PSLDV through transmission with B. tabaci MEAM1. When healthy plants of these species were fork grafted onto PSLDV‐infected plants of P. edulis, only plants of P. malacophylla remained uninfected and the virus was not detected by PCR, suggesting immunity to this begomovirus. Plants of Datura stramonium, Nicotiana benthamiana, N. clevelandii, N. tabacum ‘Xanthi’, Solanum lycopersicum (tomato cv. Compack) and several varieties of Manihot esculenta (cassava cvs IAC 118‐96, IAC 6‐01, Paranavaí, IAC 576, IAC 90 and IAC 14) were susceptible to infection with PSLDV through transmission with B. tabaci MEAM1. Adults of B. tabaci MEAM1 acquired PSLDV after 1 h of feeding on PSLDV‐infected plants of D. stramonium. They transmitted the virus to healthy plants after feeding on these plants for 1 h, although with low transmission rates. The retention time of PSLDV in the vector was 14 days.

“…CABMV is transmitted in a nonpersistent mode by aphids of several species that do not colonize passion fruit plants, except under exceptional circumstances as reported by Di Piero et al (2006) for Aphis gossypii . CABMV can also be transmitted mechanically during culturing but not through passion fruit seeds or manual pollination (Spadotti et al, 2021). Once CABMV is introduced into an orchard by viruliferous migrant aphids, the secondary spread is rapid and can reach 100% incidence in 4–8 months (Kotsubo et al, 2021; Rodrigues et al, 2016; Spadotti et al, 2019; Figure S1).…”

Cowpea aphid-borne mosaic virus (CABMV) causes passion fruit woodiness disease, which considerably reduces the lifespan and fruit production of passion fruit (Passiflora edulis; Passifloraceae) in Brazil (Fischer & Rezende, 2021). CABMV infection results in economic loss at the farmer and the national level as Brazil is the world's largest producer of passion fruit. In 2020, 46,436 ha of land was planted with passion fruit in Brazil, resulting in a yield of 690,364 tonnes and an average productivity of 14.87 t/ha (IBGE, 2022).Cowpea aphid-borne mosaic virus belongs to the genus Potyvirus, which includes several viruses that cause economically important diseases in various crops. The virus particles are flexuous and filamentous, approximately 680-900 nm, and have a genome
