Life Table Parameters of Grape Mealybug Planococcus ficus (Signoret, 1875) (Hemiptera: Pseudococcidae) On Different Vine Varieties

Abstract

In this study, the biology of grape mealybug, Planococcus ficus (Signoret, 1875) (Hemiptera: Pseudococcidae), was investigated in different grape varieties under laboratory conditions at 25 ± 1°C temperature, 65 ± 5% relative humidity, and 16:8 hours light:darkness photoperiod. Life tables of four different grapevine cultivars of Planococcus 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 cultivars were determined to be the most suitable host plants, with the highest values of life table parameters [generation time=31.6.4 ± 0.96 days, net reproductive rate = 32.3 ± 10.0 females/female/offspring, r=0.1 ± 0.01 females/female/day, gross reproductive rate=99.1 ± 16.99 nymphs/female] and (T0=38.4 ± 1.22 days, R0 = 40.8 ± 11.53 females/female/offspring, r = 9.7 ± 0.01 females/female/day, gross reproductive rate=155.1 ± 12.14 nymphs/female).
