The effects of the infection of potato (Solanum tuberosum) plants by the nonpersistent Potato virus Y (PVY) were studied on the host plant colonization behavior of different colonizing (Myzus persicae) and noncolonizing (Aphis fabae, Brevicoryne brassicae, and Sitobion avenae) aphid species. The underlying questions of this study were to know how aphids respond when faced with PVY-infected plants and whether plant infection can modify the aphid behavior involved in PVY spread. Short-range orientation behavior was observed using a dual-choice set-up and aphid feeding behavior was monitored using the electrical penetration graph technique. None of the aphid species discriminated between healthy and PVY-infected plants. Nevertheless, most individuals of M. persicae landed on and probed only in one plant whereas noncolonizing aphid species exhibited interplant movements. Study of the aphid feeding behavior showed that PVY infection essentially modified phloem and xylem ingestion. M. persicae and S. avenae exhibited an increased duration of phloem phases on PVY-infected plants whereas A. fabae showed a decreased duration of phloem phases that benefited from an increased duration of xylem ingestion phases. None of these parameters were changed in B. brassicae. These data present evidence that aphids can respond to plants infected by nonpersistent viruses. Such behavioral modifications are discussed within the context of PVY spread in potato crops.

Potato virus Y (PVY) is a reemerging problem in potato production in North America. Although the “ordinary” strain, PVYO, is still the dominant isolate in U.S. seed potatoes, the recombinant strain of the virus PVYN-Wi (= PVYN:O) has become widespread. An increase in the prevalence of a PVY strain could be due to differences in the efficiency of transmission by aphid vectors. The transmission efficiency by a clone of Myzus persicae was determined for five isolates each of PVYO and PVYN-Wi. An aphid transmission assay was developed based on the use of potato seedlings from true potato seed, allowing for greater control of plant age and growth stage. No apparent differences in transmission by M. persicae were observed. Single isolates of PVYO and PVYN-Wi were tested for their ability to be transmitted from potato to potato by five aphid species: Aphis glycines, A. gossypii, A. nasturtii, M. persicae, and Rhopalosiphum padi. Both PVY isolates showed a similar transmission phenotype in being transmitted efficiently by M. persicae but very poorly or not at all by A. glycines, A. gossypii, and R. padi. The aphid A. nasturtii transmitted both isolates with an intermediate level of efficiency. The data do not support a model for a differential aphid transmissibility being responsible for the increase in the prevalence of PVYN-Wi.

Single aphids of four species were observed with a hand-lens until each had touched its proboscis once on a tobacco plant infected with potato virus Y and then once on a healthy tobacco plant. The time that the proboscis remained touching the plants in each case was recorded. This procedure required only a few minutes for each aphid, and sometimes it was completed in less than a minute. During this process, the successful transmissions of potato virus Y by single aphids of Myzus persicae (Sulz.), Aphis abbreviata Patch, Macrosiphum solanifolii (Ashm), and Myzus solani (Kltb.) were 55, 31, 9, and 4% respectively. Vector efficiency was not due to difference in feeding behavior of these species. When single infective aphids were transferred to a series of five plants at five-minute intervals, M. persicae caused more infections and remained infective longer than A. abbreviata.

Four aphid species were identified in the Metsovo potato center, Greece. Rhopalosiphoninus latysiphon, infesting subterranean parts of potato, is reported for the first time in Greece, while Aphis frangulae, infesting the potato foliage, is reported for the first time on potato plants in Greece. High resistance to methamidophos was observed with the latter aphid species. Potato virus Y (PVY) was transmitted by all four species of aphids
