“…Variation in luteovirus transmission by aphids depends more on the interaction between aphid clones and virus isolates (Bourdin et al, 1998) than on the properties of solely the virus or the vectors (Robert & Maury, 1970;Robert, 1971;Jolly & Mayo, 1994). Clones of the M. persicae complex were previously characterized as poor, intermediate or efficient vectors of a PAT-PLRV isolate whereas they could not be separated on the basis of ability to transmit a HAT-PLRV isolate (Bourdin et al, 1998; table 1).…”

“…This circulation is made possible by specific interactions between the virus and some membrane and/or haemolymph components of the vector (van den Heuvel et al, 1994). Aphid species, clones, morphs and/or instars may vary in the efficiency with which they transmit luteoviruses (Robert & Maury, 1970;Robert, 1971;Rochow, 1972). Moreover, Bourdin et al (1998) showed that the transmission of a 'poorly aphid-transmissible' (PAT) PLRV isolate by different clones of the Myzus persicae complex ranged from 0 to 71%.…”

A prerequisite to studying the specific interactions involved in the persistent transmission of luteoviruses such as the potato leafroll virus (PLRV) is the characterization of both the virus and its vectors. A range of techniques was used to assess genetic differentiation among 27 clones belonging to the Myzus persicae complex (M. persicae (Sulzer), M. antirrhinii (Macchiati) and M. nicotianae Blackman) and showing different efficiencies in transmitting PLRV isolates. All M. persicae/M. nicotianae clones belonged to one of two karyotypes, both 2n = 12, either normal or carrying an autosomal translocation (A1,3), and all M. antirrhinii clones had 13 or 14 chromosomes. Amplified esterase 4 genes were detected by PCR-REN assay in M. persicae/M. nicotianae taxa, with gene expression being modified by methylation. Similarly, amplified E4 genes were revealed in M. antirrhinii but they all showed unmethylated. Two allozyme and 11 microsatellite loci discriminated 10 different genotypic classes among the 27 clones. Analysis of genetic relatedness between these genotypic classes revealed that M. nicotianae clones were very closely related to M. persicae clones, whereas the genetic differentiation between M. antirrhinii and M. persicae was greater. The implications of these results for the taxonomic status of these genotypes within the complex, and the transmission of PLRV, are discussed.

“…It can be transmitted by at least 11 aphid species (Kennedy et al 1962;Kostiw 1980), of which the peach-potato aphid (Myzus persicae Sulz.) is the most efficient vector (Robert and Maury 1970;Robert 1971;Sylvester 1980). PLRV can be artificially transmitted by stem grafting.…”

Potato leafroll virus (PLRV): its transmission and control

and control This review provides a wide assessment of the present state of knowledge about the potato leafroll luteovirus (PLRV), a pathogen which is seriously devastating potato crops in many parts of the world. The main biological, physical and chemical properties of this virus are described. The transmission of PLRV by aphids, which are the only transmitters of this virus under natural conditions, is characterized. Special attention is given to the control of PLRV through the use of resistant potato cultivars. Recent advances in obtaining resistant transgenic plants are outlined.

Efficacy of Mineral Oil-Insecticide Mixtures for Protection of Potato Tubers Against PVY and PVM

The impact of a dozen mixtures of the most commonly applied aphicides: Mospilan 20 SP (acetamiprid), Pirimor 500 (pirimicarb) and Karate Zeon 050 CS (lambdacyhalothrin), combined with the mineral oil Sunspray 850 EC, was researched in field conditions to assess their effectiveness in limiting potato tuber PVY, PVM and PLRV infection. In spite of the greatest reduction in the number of aphids occurring following application of Mospilan 20 SP, this treatment was not as effective in limiting PVY infection as, for example, applying Sunspray 850 EC mineral oil. Mineral oil, when used on its own or in a mixture with Pirimor 500 WG, was found to be the most effective measure for limiting PVY infection (the incidence of tubers infested with PVY was reduced by 64 % relative to control, i.e. no protection). A slightly weaker effect was observed in the case of a combination of the mineral oil with full doses of Karate Zeon 050 CS with a half of a dose of Mospilan 20 SP insecticide, however only for protection against PVY. A similar trend was observed for PVM even though a significant difference was only observed for Sunspray 850EC+Pirimor 500WG. In conclusion, the application of insecticide mixtures with mineral oil in protecting against PVY infection is not always as effective as the application of the oil itself only. Addition of the insecticide may sometimes improve the efficacy of protection, however, due to the extra costs involved, not always does it have to be economical.Resumen Bajo condiciones de campo, se investigó el impacto de una docena de mezclas de los siguientes aficidas más comúnmente aplicados: Mospilan 20 SP (acetamiprid), Pirimor 500 (pirimicarb) y Karate Zeon 050 CS (lambdacyhalothrin), combinados con el aceite mineral Sunspray 850 EC, para evaluar su efectividad en limitar la infección de tubérculo por PVY, PVM y PLRV. A pesar de la mayor reducción en el número de áfidos que se presentaron después de la aplicación de Mospilan 20 SP, este tratamiento no fue tan efectivo en limitar la infección de PVY como, por ejemplo, con la aplicación del aceite mineral Sunspray 850 EC. El aceite mineral, al usarlo solo o en mezcla con Pirimor 500 WG, se encontró que era la medida más efectiva para limitar la infección de PVY (la incidencia de tubérculos infectados con PVY se redujo en un 64 % con respecto al testigo sin protección). Se observó un efecto ligeramente más débil en el caso de la combinación del aceite mineral con dosis completa de Karate Zeon 050 CS con la mitad de la dosis del insecticida Mospilan 20 SP, aunque fuera solamente para protección contra PVY. Se observó una tendencia similar para PVM, aun cuando se observó diferencia significativa solamente para Sunspray 850EC+pirimor 500 WG. En conclusión, la aplicación de mezclas de insecticidas con aceite mineral en la protección contra la infección de PVY no es siempre tan efectiva como la aplicación únicamente del aceite solo. La adición del insecticida puede mejorar algunas veces la eficacia de la protección, no obstante, debido al costo extr...
