Feeding Behavior of Cryptolaemus Montrouzieri Mealybugs Parasitized by Anagyrus Pseudococci
(Springer, 2008) Mustu, M.; Kilincer, N.; Ulgenturk, S.; Kaydan, M. B.
The citrus mealybug Planococcus citri (Risso) and the vine mealybug Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae) are two worldwide polyphagous pests of citrus, vineyards and ornamental plants in greenhouses. Biological control of these pests may rely on the combined release of parasites and predators, which can be affected by intraguild predation (IGP). This Study investigated the feeding behavior of different stages of Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae) on mealybugs parasitized by Anagyrus pseudococci (Girault) (Hymenoptera: Encyrtidae) 2, 4, 6, 8 and 10 days. The study was conducted in a climate-controlled room at 28 +/- 1 degrees C, 16L:81), and 65 +/- 10% r.h. The highest consumption values for all stages of C. montrouzieri occurred with 2- and 4-day parasitized mealybugs, whereas the predator did not feed on either species of mealybug parasitized for longer periods, due to the onset of mummification.
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.

(Springer, 2006) Kaydan, M. B.; Kilincer, N.; Uygun, N.; Japoshvili, G.; Gaimari, S.
Natural enemies of mealybugs were surveyed in Ankara, Turkey, during the years 2001 to 2003. Twenty-three predatory species belonging to the insect orders Coleoptera (Coccinellidae, 17), Diptera (Chamaemyiidae, 3) and Neuroptera (Chrysopidae, 2; Hemerobiidae, 1); and 22 parasitoid species belonging to Hymenoptera (Aphelinidae, 2; Encyrtidae, 14; Platygasteridae, 1; Pteromalidae, 3; Signiphoridae, 2) were determined. The following ten species are newly recorded for the Turkish fauna: Sidis biguttatus Motchulsky, Nephus sinuatomaculatus Sahlberg (Coccinellidae), Leucopomyia alticeps Czerny, Parochthiphila (Euestelia) decipia Tanasijtshuk (Chamaemyiidae), Leptomastidea matritensis Mercet, Prochiloneurus bolivari Mercet, Rhopus sp.nr. acaetes (Walker), Stematosteres sp., Eunotus acutus Kurdjumov, and Chartocerus kurdjumovi (Nikol'skaya) (Chalcidoidea).
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.
Visual and Olfactory Cues for Catching Parasitic Wasps (Hymenoptera: Scoliidae)
(Hungarian Natural History Museum, 2012) Vuts, J.; Razov, J.; Kaydan, M. B.; Toth, M.
Scoliid wasps (Scolia spp.) are day-flying flower visitors. Earlier field observations indicated preference of Scolia hirta, S. flavifrons and S. sexmaculata for a combination of a light blue colour and a quaternary floral blend [(E)-anethol, 3-methyl eugenol, 1-phenylethanol and lavandulol] constituents of traps used for catching the scarabs Cetonia aurata aurata and Potosia cuprea. Subsequent field experiments for Scolia hirta, S. flavifrons and S. sexmaculata in Hungary, Croatia and Turkey, respectively, comparing different colours and floral blends previously found efficient for catching several scarab species, confirmed observations on the preference of scoliids for the Cetonia/Potosia trap. When investigating the relative importance of the colour and the quaternary floral blend released from the Cetonia/Potosia trap for S. hirta, joint application of the visual and chemical cues resulted in a significant increase of catches, compared to those in traps containing only one of the cues, or in unbaited traps with no colour. An explanation of the activity of the Cetonia/Potosia trap on scoliid wasps can be that, since the wasps feed on flowers and the bait of the Cetonia/Potosia trap comprises common floral compounds, it represents olfactory stimuli essential in host plant-finding. Role of the blue colour also seems to be important, however, more detailed comparative studies, including different colours and chemicals, are necessary to better understand interactions mediating host plant-finding. Possibilities of practical application of the Cetonia/Potosia trap for monitoring S. hirta and S. flavifrons are discussed.
