Effects of Tobacco Varieties on Eidonomy and Life Table Parameters of the Aphid Species Myzus Persicae (Hemiptera: Aphididae)

Abstract

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- i̇çgeçit, Bursa 18000, Diyarbakir, Düzce- Özbaş, İzmir-Karabaǧlar 6265, Malatya, Samsun-Maden, Trabzon 209/87, Tömbeki 7703) at 26±1 °C, 65±10% RH and 14:10 h (l:d) light under laboratory conditions. The developmental time for the immature stages ranged from 5.46 days on İzmir-Karabaǧlar 62/65 -7.25 days on Tömbeki 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, İzmir-Karabaǧlar 6265, Malatya, Bitlis-Īçgeçit, Düzce-Özbaş, Bursa 18000, Tömbeki 7703, respectively. Longevity of females ranked from 32.80 days on Trabzon 209/87 -26.00 days on Tömbeki 7703. Population growth rate (rm) for green peach aphid was the highest on Samsun-Maden and the lowest on Tömbeki 7703. Values of rm varied from 0.401 on Samsun-Maden to 0.287 on Tömbeki 7703. The mean population generation time of varieties tested ranged from 11.88 on Samsun-Maden to 14.06 days on Tömbeki 7703. According to results obtained in this study Tömbeki 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. © 2006 E.
