    Development and Life Table Parameters of Phenacoccus madeirensis Green (Hemiptera: Pseudococcidae) on Four Ornamental Plants
    (Entomological Soc Brasil, 2016) Tok, B.; Kaydan, M. B.; Mustu, M.; Ulusoy, M. R.
    The development, reproduction, and life table parameters of the Phenacoccus madeirensis Green (Hemiptera: Pseudococcidae) on four ornamental plant species, namely Pelargonium zonale (Geraniaceae), Hibiscus rosa-sinensis, Hibicus syriacus (Malvaceae), and Cestrum nocturnum (Solanaceae) were investigated under controlled conditions (25 +/- 2A degrees C, 60 A +/- 10% R.H., and 16 h photophase). Life table data were analyzed by using an age-stage two-sex life table. The shortest total immature developmental time of females and males for P. madeirensis was obtained on C. nocturnum (20.42 and 21.90 days, respectively). The highest fecundities were 233 and 232 eggs on C. nocturnum and H. syriacus, respectively. The intrinsic rate of increase (raEuro dagger aEuro parts per thousand= 0.1511 day(-1)) and finite rate of increase (lambda aEuro dagger aEuro parts per thousand= aEuro dagger 1.1631 day(-1)) were the greatest when mealybugs were reared on C. nocturnum. Net reproductive rate (R (0)aEuro dagger aEuro parts per thousand= aEuro dagger 129.5 offspring) was the greatest when reared on H. syriacus, but this value was not statistically different from that on C. nocturnum. The shortest mean generation time (TaEuro dagger aEuro parts per thousand= aEuro dagger 31.3 days) was calculated on C. nocturnum. These results indicate that C. nocturnum and H. syriacus are more suitable hosts than H. rosa-sinensis and P. zonale for P. madeirensis.

    Investigation of mealybug (Hemiptera: Coccoidea: Pseudococcidae) species from Turkey by RAPD
    (Priel Publ, 2007) Serce, C. Ulubas; Kaydan, M. B.; Kilincer, A. N.; Ertunc, F.
    Molecular markers are commonly used for determining the relationship between insect species. In this study, we investigated the relationship of six mealybug species, Planococcus citri (Risso), Planococcus ficus (Signoret), Planococcus vovae (Nasonov), Pseudococcus longispinus (Targioni Tozzetti), Pseudococcus viburni (Signoret) and Phenacoccus aceris (Signoret), sampled from Turkey, using randomly amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR). Of the 50 RAPD primers tested, 18 identified a total of 256 fragments of which all were polymorphic. Sufficient discrimination between P. citri and P ficus was provided by several RAPD primers. The genetic distance values calculated for each pair-wise comparison ranged from 0.156 to 0.504. Cluster analyses of RAPD data clearly separated the species into two groups.
