“…Cucumis anguria is a common weed in Brazilian crops, particularly in papaya orchards, and it has not been related with natural infection of PRSV-P; however, other cucurbits such as Momordica charantia L., and Cucurbita maxima Duchesne cv. Exposição (pumpkin) were not infected by PRSV-P though mechanical or aphid inoculations, and field exposure of plants (Spadotti et al, 2013;Mansilla et al, 2013). These data indicate that these cucurbits species do not seem to have a role in the epidemiology of the papaya ringspot in Brazil.…”

Papaya ringspot, one of the most important diseases of papaya, is caused by Papaya ringspot virus type P (PRSV-P), which is transmitted by various aphid species. Objectives of this research were to identify the aphid species and their weed hosts of papaya orchards in the major papaya producing and exporting region of Brazil in northern Espírito Santo State. Aphids were collected from weed hosts, and with M€ oericke-type traps in papaya orchards of twenty farms in Linhares, Sooretama and Aracruz municipalities of Espírito Santo, Brazil. A total of forty aphid species were collected, of which 22 are new records in the State. Thirty-eight aphid species were identified from traps, including Aphis craccivora Koch, A. gossypii Glover, A. spiraecola Patch, Myzus persicae (Sulzer), and Toxoptera citricidus (Kirkaldy), known vectors of PRSV-P. Cryptomyzus Oestlund (Aphididae) is recorded for the first time in Brazil. Thirteen aphid species associated with 22 weed species of 14 families were collected. Aphis gossypii, which has been reported to be one of the most efficient vectors of PRSV-P, infested the greatest number of weed hosts. Chamaesyce hyssopifolia (L.) Small, Euphorbia hirta L. (Euphorbiaceae), Commelina benghalensis L. (Commelinaceae), Lepidium virginicum L. (Brassicaceae) and Sida sp. (Malvaceae) were the most frequently infested weeds. Commelina benghalensis was infested by the greatest number of aphid species during this study. Integrated management of weed hosts of aphids to reduce aphid populations in papaya orchards may be useful for control of PRSV-P. Based on accurate knowledge of the aphid and weed species present in papaya orchards obtained in this study, integrated pest management efforts may be more efficiently directed toward eliminating the most frequently infested weed species that serve as hosts for aphid vectors of PRSV-P.

“…In the case of papaya ringspot, only papaya is the principal source of PRSV‐P inoculum. Although this potyvirus can infect some species of Cucurbitaceae, they do not appear to be important in the epidemiology of papaya ringspot (Mansilla et al , ; Spadotti et al , ). In the case of passion flower, there is evidence that the sources of inoculum appear to be mainly the two cultivated species ( P. edulis and P. alata ) and some wild Passiflora species, reported as susceptible to CABMV (Maciel et al , ).…”

In Brazil, passion flower is grown across almost the entire country. The predominant disease of the passion flower crop is passion fruit woodiness, caused by the potyvirus cowpea aphid‐borne mosaic virus (CABMV), and transmitted by aphids in a nonpersistent manner. The disease reduces the useful life of the orchard from 36 months to approximately 18 months. Up to now, there has not been an efficient method for disease management. The aim of this work was to evaluate the efficiency of systematic roguing of diseased plants through weekly inspections, for disease management in the field. The latent and incubation periods of CABMV in passion flower vines were determined in order to optimize roguing efficiency. Passion fruit plants inoculated with CABMV started to act as sources of inoculum from 3 days after inoculation (DAI), and the symptoms were expressed, on average, at 8 DAI. Five field experiments, conducted in the states of São Paulo and Bahia, Brazil, demonstrated that systematic roguing of diseased plants was significantly efficient for managing passion fruit woodiness disease. In order to facilitate identification and subsequent removal of the infected plants, they need to be grown separately. This cultural practice can be recommended for managing passion fruit woodiness disease, provided it is applied on a regional scale by all passion fruit growers. The development of some pilot plantings for the application of roguing in a passion flower‐producing region is recommended to validate the use of this technique for managing passion fruit woodiness disease.

“…They also identified one Solanaceae species: Solanum americanum. Chin et al (2007) reported that Momordica charantia is a PRSV-P carrier; however, Spadotti et al (2013), after evaluating it through mechanical inoculation and aphid vectors, stated that Momordica charantia is not susceptible to any of the PRSV strains (P and W). In this research, we found a M. charantia specimen from Los Asmoles that appeared healthy and gave negative DAS-ELISA and RT-PCR test results.…”

“…Recientemente, Martins et al (2016), colectaron en Brasil áfidos vectores presentes en 22 especies arvenses de plantaciones de papayo, la mayoría pertenecientes a las familias Euphorbiaceae, Commelinaceae, Brassicaceae y Malvaceae, también se identificó una Solanaceae: Solanum americanum. Chin et al (2007) reportaron a Momordica charantia como portadora de PRSV-P, sin embargo, Spadotti et al (2013) determinaron que ésta especie no es susceptible a ninguna de las cepas de PRSV (P y W), tras evaluar su inoculación mecánica y mediante áfidos vectores en la especie antes mencionada. En este estudio se encontró un ejemplar de M. charantia proveniente de Los Asmoles, el cual tuvo una apariencia sana y presentó un resultado negativo a PRSV por DAS-ELISA y RT-PCR, sin embargo, resulta conveniente analizar en un futuro un mayor número de muestras de esta especie para determinar si puede actuar como reservorio del virus.…”

Papaya ringspot virus (PRSV) es un Potyvirus de importancia económica para el cultivo de papayo (Carica papaya L.) produciendo síntomas de mosaico, clorosis y deformación en las hojas, así como manchas características en forma de anillo en el fruto. En México no existen reportes de especies de arvenses asociadas a este cultivo que actúen como reservorio del Potyvirus. En el presente trabajo, se identificó la presencia de PRSV en arvenses de plantaciones comerciales de papayo del estado de Colima, México. En un muestreo de 139 plantas de papayo y 70 arvenses con sintomatología de virosis, se detectó a PRSV en un 40 y 50% para Carica papaya y Cucurbita pepo respectivamente mediante DAS-ELISA (Ensayo por inmunoabsorción ligado a enzimas con doble anticuerpo en sándwich), mientras que el análisis de la secuencia de 350 pares de bases de la región NIb de PRSV generados por RT-PCR (reacción en cadena de la polimerasa con transcriptasa reversa) permitió identificar al Potyvirus en un 40 a 90% del total de muestras de Abutilon abutilastrum y Anoda cristata (Malvaceae), así como Solanum rostratum (Solanaceaea), lo que representa un nuevo reporte de arvenses reservorio de PRSV asociadas a plantaciones de papayo en México.
