Effects of tobacco varieties on eidonomy and life table parameters of the aphid species Myzus persicae (Hemiptera: Aphididae)

The development, longevity, reproduction, and life table parameters of the green peach aphid, Myzus persicae Sulzer 1776, were evaluated on ten commonly grown varieties of Nicotiana tabacum (Adiyaman, Bitlis-Icgecit, Bursa 18000, Diyarbakir, Duzce-Ozbas Izmir-Karabaglar 6265, Malatya, Samsun-Maden, Trabzon 209/87, Tombeki 7703) at 26 +/- 1 degrees C, 65 +/- 10% RH and 14:10 h (I:d) light under laboratory conditions. The developmental time for the immature stages ranged from 5.46 days on Izmir-Karabaglar 62/65 -7.25 days on Tombeki 7703. The average number of nymphs reproduced per female were 88.94, 88.58, 83.22, 80.77, 75.92, 71.54, 70.22, 69.88, 68.20 and 54.70 on Samsun-Maden, Adiyaman, Trabzon 209/87, Izmir-Karabaglar 6265, Malatya, Bitlis-Icgecit, Duzce-Ozbas, Bursa 18000, Tombeki 7703, respectively. Longevity of females ranked from 32.80 days on Trabzon 209/87 -26.00 days on Tombeki 7703. Population growth rate (r(m)) for green peach aphid was the highest on Samsun-Maden and the lowest on Tombeki 7703. Values of r(m) varied from 0.401 on Samsun-Maden to 0.287 on Tombeki 7703. The mean population generation time of varieties tested ranged from 11.88 on Samsun-Maden to 14.06 days on Tombeki 7703. According to results obtained in this study Tombeki 7703 appeared to be the most resistant while Samsun-Maden appeared to be the most susceptible to the green peach aphid among the varieties tested.
