In this study, the biology of Grape mealybug, Planococcus ficus (Signoret, 1875) (Hemiptera: Pseudococcidae) was investigated on different grape varieties under laboratory conditions at 25 ± 1 0C temperature, 65 ± 5% RH and 16:8 h L: D photoperiod. Life tables of four different grapevine cultivars of P. ficus were created, two of which are for wine (Emir, Kalecik karası) and two for table grapes (Yalova incisi, Trakya ilkeren). The results determined that the most suitable vine varieties for pest development were Emir and Yalova incisi, which are white grape varieties. The Yalova incisi and Emir cultivar was determined as the most suitable host plant, with the highest values of life table parameters (T0 = 31,6.4 ± 0,96 days, R0 = 32,3 ± 10,0 female/female/offspring, r = 0,1 ± 0.01 female /female/day, GRR = 99,1 ± 16,99 nymphs/female) and (T0 = 38.4 ± 1.22 days, R0 = 40.8 ± 11.53 female/female/offspring, r = 9.7 ± 0.01 female /female/day, GRR = 155.1 ± 12.14 nymphs/female). |
