    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.

    Some Biological Interactions Between the Parasitoid Anagyrus Pseudococci (Girault) (Hymenoptera: Encyrtidae) and Its Host Planococcus Ficus (Signoret) (Hemiptera: Coccoidea: Pseudococcidae)
    (Springer Heidelberg, 2007) Gulec, G.; Kilincer, A. N.; Kaydan, M. B.; Ulgenturk, S.
    The development, longevity, fecundity and life-table parameters of the endoparasitoid Anagyrus pseudococci (Girault) (Hymenoptera: Encyrtidae), 15 d.o. (3rd-instar nymphs) and 21 d.o. (young adult females) of the vine mealybug, Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae) at 28 +/- 1 degrees C, 65 +/- 10%RH and 16:8h L:D under laboratory conditions. The developmental time of female parasitoids within the host was 17.7 +/- 0.39 days in 15 d.o. and 16.65 +/- 0.25 days in 21 d.o. hosts; for males, development time was 16.85 +/- 0.29 and 15.25 +/- 0.09 days, respectively. The average number of offspring per female was 22.35 +/- 1.68 in 15 d.o. and 34.8 +/- 2.56 in 21 d.o. vine mealybugs. The longevity of female parasitoids was 14.8 +/- 0.98 days in 15 d.o. and 15.65 +/- 0.92 days in 21 d.o. mealybugs, respectively; for males, longevity was determined as 7.3 +/- 0.43 and 6.7 +/- 0.54 days, respectively. The mean time of pupation was 7.85 +/- 0.003 days in 15 d.o. mealybugs and 8.65 +/- 0.003 days in 21 d.o. mealybugs. The aggregate encapsulation rate in the parasitized 15 d.o. mealybugs was 49.73 and 60.36% in 21 d.o. mealybugs. Furthermore, effective encapsulation was 24.82% in 15 d.o. mealybugs and 37.50% in 21 d.o. mealybugs. Population growth rate (r(m)) for A. pseudococci was 0.0999 female/female/days in 15 d.o. mealybugs and 0.1269 female/female/days in 21 d.o. mealybugs. The mean population generation time was 23.49 days for parasitoids reared in 15-days-old and 22.39 days when reared in 21 d.o. mealybugs.
