Abstract:In a 3-year field study in cucurbits infected with potyviruses, alate aphids trapped alive on a vertical screen or in horizontal suction or yellow-pan traps were tested individually on virus-susceptible plants for virus (natural) infectivity. Trap types differed in effectiveness for trapping some aphid species. Of 40 species of aphids tested for natural infectivity, 4 transmitted virus: Aphis citricola Van der Goot, A. middletonii (Thomas), A. illinoisensis Shimer, and Myzus persicae (Sulzer). Of these, 92.0% of all infective aphids were either A. citricola (52.0%)or A. middletonii (40.0%). In another study, 7 of 23 species of aphids trapped alive where there were no infected cucurbits, and fed on sources of watermelon mosaic virus 2 (WMV-2) or zucchini yellow mosaic virus (ZYMV)in the laboratory, transmitted the virus. Of these transmissions, 93.1% were by three species: A. citricola (48.3%), A. middletonii (27.6%), or M. persicae (17.2%). Their efficiency rates were 18.3, 30.8, and 23.8%, respectively. Average rate of transmission of WMV-2 was 9.7% and of ZYMV was 21.4%.
