“…In general, acceptance of collard was much lower than that of any of the other three hosts. The thick, waxy cuticle of collard may account for this non-preference (Annis et al, 1982). However, there were no clear patterns of preference or non-preference for the other three hosts.…”

Prior to designation as distinct species, an appellation presently in question, the tobacco aphid, Myzus nicotianae Blackman (Homoptera: Aphididae), was classified as a tobacco‐feeding form of the green peach aphid, Myzus persicae (Sulzer). In this study, RAPD polymorphisms distinguished members of the Myzus persicae complex (M. persicae and M. nicotianae) from three outgroup Myzus species (M. cerasi (F.), M. hemerocallis Takahashi, and M. varians Davidson). Polymorphisms within the complex did not separate populations on the basis of host association (tobacco versus other host plants) or geographic origin (collections from the United States, Europe, and Japan). Similarly, while GC‐MS analysis of cuticular hydrocarbon profiles revealed both developmental and inter‐populational differences within the M. persicae complex, it did not separate populations of tobacco feeding aphids from those collected off non‐tobacco hosts. Finally, with the exception of their responses to a choice between lettuce and collards, the host preference behavior of a green peach aphid population, a red tobacco aphid population, and a green tobacco aphid population was indistinguishable in host preference experiments. These results add to a growing body of evidence suggesting M. nicotianae and M. persicae are conspecific.

“…1A). This also indicates that aphids are more restless on resistant cowpea lines than on the susceptible or tolerant ones just as has been demonstrated in other aphidhost combinations (McMurtry & Stanford, 1960;Kennedy, 1976;Annis et al, 1982;Ferguson et al, 1982). It therefore follows that alatae from outside the plot would spread CAMV more rapidly in a field of aphid-resistant cowpea plants (primary spread) on account of their restlessness than in one of either aphid-tolerant or aphid-susceptible plants.…”

“…In a previous study , it was shown that resistance to aphid infestation in cowpea would not provide resistance to infection with cowpea aphid-borne mosaic virus (CAMV), the most widespread virus of cowpea (Allen, 1983). This is partly because aphids are restless when placed on resistant or non-preferred host plants (McMurtry & Stanford, 1960;Gibson & Plumb, 1977;Annis et al, 1982), thus ensuring the rapid mobility of aphids and the consequent spread of viruses. Furthermore, the comparatively short, frequent aphid probes on aphid-resistant plants (Adams & Wade, 1976;Kennedy et al, 1978;Tarn & Adams, 1982; is a behavioural characteristic well-suited to the spread of a nonpersistent virus such as CAMV.…”

The settling behaviour of Aphis craccivora Koch, the vector of cowpea aphid‐borne mosaic virus (CAMV) in cowpea, Vigna unguiculata (L.) Walp., on aphid‐resistant, aphid‐tolerant and aphid‐susceptible cowpea lines was investigated. It was found that although apterae counts on the aphid‐susceptible and aphid‐tolerant lines were higher than on the aphid‐resistant ones, apterae were more widely dispersed among the latter. Whereas there was a positive significant correlation between alatae numbers and incidence of CAMV in the aphid‐susceptible and aphid‐tolerant lines, this correlation was negative in the aphid‐resistant ones. However, the incidence of CAMV was not significantly different from each other in all the lines. This indicated that aphid activity (e.g. wide dispersal) was more important in the spread of CAMV than the absolute number of viruliferous alatae, an effect which was manifested on the aphid‐resistant lines. Aphids acquire CAMV more readily from aphid‐susceptible and aphid‐tolerant source plants than from aphid‐resistant ones. The significance of this in relation to secondary spread of CAMV and the effect of noncolonising aphids are discussed. Résumé Le comportement d'atterissage d'Aphis craccivora et l'acquisition du virus de la mosaïque transmis par puceron chez les variétés de niébe résistantes au puceron Le comportement d'atterissage d'Aphis craccivora, vecteur du virus de la mosaique transmis par puceron (CAMV) sur Vigna unguiculata, a été examiné sur des variétés résistantes, sensibles ou tolérantes aux pucerons. On a observé que bien que les dénombrements d'aptères sur variétés sensibles ou tolérantes aient été plus élevés que sur variétés résistantes, les aptères étaient plus largement dispersés sur ces dernières. Tandis qu'il y avait une corrélation positive significative entre les nombres d'ailés et la présence de CAMV sur les variétés sensibles et tolérantes aux pucerons, cette corrélation était négative sur les variétés résistantes. Cependant, la fréquence de CAMV n'était pas significativement différente parmi toutes ces variétés. Ceci a montré l'activité des pucerons (c'est à dire leur dispersion) était plus importante dans la diffusion du CAMV que le nombre absolu d'ailés virosés, effet qui était manifeste sur les variétés résistantes aux pucerons. Les pucèrons contaminés au CAMV le sont plus par des plantes sensibles ou tolérantes aux pucerons que par des plantes résistantes. La discussion porte sur la signification de ceci en relation avec la diffusion secondaire de CAMV, et de l'effet des pucerons non colonisateurs.

“…Another explanation for differences in infection levels between cultivars may be that aphids are selectively attracted to some cultivars over others. Host preference by aphids has been demonstrated though preference for a specific cultivar has not been established (Annis et al 1982;Srinivasan and Alvarez 2007). If aphids can selectively choose one cultivar over another in side by side rows, then a better understanding of preferential selection is needed.…”

Potato Cultivars Differ in Current Season Potato Virus Y (PVY) Infection

Research plots were established in 2004, 2005, and 2006 at Hermiston, Oregon and in 2005 and 2006 in Othello, Washington to determine if potato cultivars differ in current season PVY infection. Eight potato cultivars were used; Gem Russet, GemStar Russet, Russet Norkotah, Shepody, Alturas, Ranger Russet, Umatilla Russet and Russet Burbank. The first four listed produce mild symptoms due to current season infection with PVY. Cultivars were planted in a randomized complete block design with four replications where each block contained a single 50-hill row for each cultivar. Leaf samples were evaluated monthly via ELISA to follow naturally occurring PVY infection. Cultivars that produce mild symptoms had higher current season infection levels. Over the 3 years at Hermiston, Shepody (93.8%), Gem (92.8%), Gemstar (89.8%) and Russet Norkotah (82.7%) had the highest infection levels, while Russet Burbank (68.8%), Umatilla Russet (58.0%), Ranger Russet (49.6%) and Alturas (48.1%) had the least infection. At Othello, infection levels were much lower and cultivar differences were minimal though Gem Russet had the highest current season infection (30.4%), Ranger Russet had the lowest (4.9%) and was significantly lower than Gem Russet and Shepody. Higher levels of infection occurred in 2006 at Hermiston and Othello (77.1% and 18.2%, respectively) compared to 2005 (66.7% and 10.2%, respectively). This is the first report where different cultivars of potatoes, growing side by side, had different levels of PVY infection. Possible explanations for differing current season infection levels between cultivars are discussed. Resumen Se establecieron lotes experimentales en 2004, 2005, y 2006 en Hermiston, Oregon, y en 2005 y 2006 enOthello, Washington, para determinar si variedades de papa difieren en un ciclo en infección por PVY. Se utilizaron ocho variedades; Gem Russet, GemStar Russet, Russet Norkotah, Shepody, Alturas, Ranger Russet, Umatilla Russet y Russet Burbank. Las primeras cuatro de la lista producen síntomas ligeros debido a la infección por PVY en el mismo ciclo de cultivo. Las variedades se plantaron en un diseño de bloques completos al azar con cuatro repeticiones, donde cada bloque contenía un surco sencillo de 50 plantas por variedad. Se evaluaron mensualmente muestras de hoja con ELISA para seguir la infección natural por PVY que se fuera presentando. Las variedades que producen síntomas ligeros tuvieron los niveles de infección más altos durante el ciclo. En los tres años en Hermiston, Shepody (93.8%), Gem (92.8%), Gemstar (89.8%) y Russet Norkotah (82.7%), tuvieron los niveles mas altos de infección, mientras que Russet Burbank (68.8%), Umatilla Russet (58.0%), Ranger Russet (49.6%) y Alturas (48.1%) tuvieron la infección mas baja. En Othello, los niveles de infección fueron mucho mas bajos y
