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.

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.

Paraffin Oil

In laboratory tests with a light white paraffin oil, transmission of potato virus Y by viruliferous adults of Myzus persicae (Sulz.) was impeded by (a) allowing aphids to probe on a leaf coated with oil, (b) manually touching the end of the labium to an oil-coated leaf, or (c) inserting the bare stylets directly into the oil. The first two of these but not the third also impeded for some minutes the uptake and transmission of virus Y by nonviruliferous aphids. Oil sprayed on plants kept in the laboratory continued to cause these effects for some weeks. If infected plants, used as virus sources for aphids, were coated with oil, transmission from them was impeded. It is still not clear why oil impedes transmission. But the results give good reasons to believe that oil can be used in the field to prevent spread of certain aphid-borne viruses.

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.

Test tube plantlets were used to assess the transmission efficiency of Potato virus Y (PVY) from and to potato plants by the potato colonizing species green peach aphid (Myzus persicae) and the non-potato colonizing species soybean aphid (Aphis glycines). Similar levels of transmission of PVY by M. persicae were observed in the test tube plantlets and potted plants, demonstrating the reliability of this test for PVY transmission efficiency assay for aphids. The assay was then used to assess the transmission of PVYO and PVYN:O by M. persicae and A. glycines with two virus acquisition regimes, one with 5-min continuous probing and the other with 1-h acquisition access. The M. persicae mediated-transmission rate was 24.1% and 51.7% for PVYO and PVYN:O, respectively, under the 5-min acquisition regime; under the same acquisition regime, A. glycines led to 0.0% and 1.7% infection rates for PVYO and PVYN:O, respectively. Under the 1-h acquisition regime, no infection was observed except for PVYN:O by M. persicae, which exhibited an infection rate of 3.4%.

Potato virus Y (PVY) was made noninfective by incubation with formaldehyde in vitro. Yet this noninfective virus reacted with PVY antiserum and caused antibodies to be produced in rabbits as readily as infective PVY. A method is described for baring the stylets of living aphids beyond the end of the labium, which normally encloses the stylets. Specimens of Myzus persicae (Sulz.) infective with PVY were made noninfective by treating the stylets for 30 sec. with concentrations of formaldehyde as low as 0.03%; and 0.25% formaldehyde caused the same effect in five seconds. Aphids were also made noninfective when the proboscis with the tip of the stylets bared was treated with formaldehyde, even after the stylets had been inserted a considerable distance into infected tobacco plants. By contrast, aphids usually remained infective when the proboscis with the stylets enclosed in the labium was treated with similar concentrations of formaldehyde. However, formaldehyde treatment of the stylets did not affect the ability of aphids immediately thereafter to acquire and transmit PVY. These results are compatible with the hypothesis that viruses transmitted like PVY are carried by the stylets of their aphid vectors.
