Green peach aphids infective with potato virus Y were made noninfective by exposing the tips of their stylets to ultraviolet radiations in the 2537 Å wave band. Similar results were obtained when the area around the aphid was ventilated during irradiation to carry away the ozone produced by the radiations passing through the air. This irradiation did not appear to harm the aphid even though much of its body was irradiated at the same time. Nor did it affect the infectivity of aphids when their stylets were enclosed by the labium, or when most of the length of the stylets except the tips was exposed to the radiations. Irradiation did, however, reduce the ability of aphids immediately thereafter to acquire potato virus Y during a brief feeding puncture, but this was so whether the tips of the stylets were irradiated or not. Furthermore, an hour after being irradiated, aphids acquired the virus during a brief feeding puncture as readily as did unirradiated controls. It is concluded that irradiation of the tips of the stylets of M. persicae inactivated potato virus Y that otherwise would have been transmitted to the test plants. Only virus near the tips of the stylets appeared to be transmitted even after more than the tips had been inserted into infected tobacco plants.

AbstractA cardboard trap, painted yellow and coated with STP® oil treatment, was more efficient in trapping Myzus persicae (Sulzer) than water traps using Stickem®. STP-coated traps were more selective than Stickem-coated traps for small insects and caught more aphids per unit area than did water traps. Aphids were identified in situ on STP traps more quickly than from water traps or traps coated with Stickem.

Nicandra Physalodes

Green peach aphids reared on turnip stecklings acquired a virus that was transmitted to plants of Physalis floridana Rydb. and P. pubescens L., hosts used in potato leaf roll studies. Symptoms on these hosts consisted of a yellowing of the veins of the leaves. Nicandra physalodes L., when infected, showed severe stunting and chlorosis. The virus was carried without symptoms on turnips and showed only slight stunting on several species of Brassica. It was not transmitted by mechanical inoculation and it does not appear to be similar to any of the viruses previously reported in turnips. The aphid Myzus persicae (Sulzer) acquired the virus during a seven-hour feeding period, and after a latent period of approximately 23 hr., transmitted the virus during a one-hour test-feeding period. Once infective, aphids remained so for several days.

AbstractA method which uses the number of large embryos per adult to predict increases or decreases of green peach aphids, Myzus persicae (Sulzer), on potatoes over 3–4 or 7–8 days is presented. The population change between two successive counts 1 and 2, expressed as an increase factor (count 2 divided by count 1), is related to the average number of embryos per adult, at the time of count 1, by a linear regression (significant, P < 0.001). If there are more than about three embryos per adult, the population increases. Parasitism by Aphidius nigripes Ashm. reduces the number of embryos per adult in the field. In the laboratory, with no parasitism, the number of embryos per adult declines with age and is directly related to the daily birth rate which also declines with age.

AbstractScymnus marginicollis Mannerheim was reared on green peach aphids, Myzus persicae (Sulzer). At 20°–25 °C and a 16-h photoperiod, durations of egg, larval, and pupal stages were about 5, 10, and 7 days, respectively. Adults survived more than 80 days. The ingestion of wax-producing prey was not required for the beetle larvae to produce their woolly wax covering. Larvae fed exclusively by sucking fluids from appendages of the aphid prey. The coccinellid consumed about 16 adult aphids during the larval stage. Adults fed on fluids and tissues of M. persicae. Female adults consumed about five aphids per day, nearly twice as many as did males. The beetle populations increased in July and reached peak abundance in August. The seasonal trend of S. marginicollis suggests one generation per year.
