    Co-Authors: Helmut Rauleder, Klaus Schrameyer, Olaf Zimmermann
    Abstract:

    In 2015 within an initial test for the biological regulation of the White Scale (Diaspididae: Pseudaulacaspis Pentagona ) in a fruit orchard near house gardens in Pfinztal-Soellingen near Karlsruhe on heavily infested mulberry ( Morus nigrum ) a predatory gall midge Lestodiplosis diaspidis (Kieffer, 1910) (Nematocera: Cecidomyiidae) has been detected. This is the first record of this beneficial species for Germany. The importance of this gall midge as an antagonist of White Scale should be investigated in further studies. Im Jahr 2015 wurde bei einem Tastversuch zur biologischen Regulierung der Maulbeerschildlaus (Diaspididae : Pseudaulacaspis Pentagona ) in einem an einen Obstbaubetrieb angeschlossenen Hausgarten in Pfinztal-Söllingen nahe Karlsruhe an einem mit Maulbeerschildläusen stark befallenem Maulbeerbaum ( Morus nigrum ) eine räuberisch lebende Gallmücke der Art Lestodiplosis diaspidis (Kieffer, 1910) (Nematocera: Cecidomyiidae) als räuberischer Gegenspieler der Maulbeerschildlaus nachgewiesen. Der Fund dieses Nützlings ist ein Erstnachweis für Deutschland. Die Bedeutung der nachgewiesenen Gallmücken als Gegenspieler der Maulbeerschildlaus sollte in weiteren Untersuchungen geklärt werden.

  • Antagonisten und Prädatoren der Maulbeerschildlaus Pseudaulacaspis Pentagona (Targioni-Tozzetti, 1886) (Homoptera: Diaspididae) in Baden-Württemberg
    Erwerbs-Obstbau, 2011
    Co-Authors: Helmut Rauleder
    Abstract:

    Die Erhebungen zur Antagonisten Fauna der Maulbeerschildlaus ( Pseudaulacaspis Pentagona, Targioni-Tozzetti, 1886) wurden 2009 bis 2010 in der Obstanlage des Lehr- und Versuchsbetriebes für Obstbau am Landwirtschaftlichem Technologiezentrum Augustenberg (LTZ) an Pfirsich und Süßkirsche sowie 2010 an vier weiteren Standorten an roter und schwarzer Johannisbeere in Baden-Württemberg durchgeführt. Im Mittelpunkt der Untersuchungen stand die Ermittlung der Nützlingsfauna und der Parasitierungsrate der Maulbeerschildlaus in befallenen Erwerbsobstanlagen mittels Fotoeklektoren, die im Labor mit befallenen Astproben der verschiedenen Wirtspflanzen versehen wurden. Weiterhin wurden im Freiland (LTZ) Beobachtungen zu Prädatoren des Schädlings durchgeführt. Es wurden zwei Zehrwespenarten ( Aphytis diaspidis ; Howard, 1881 und Encarsia berlesei ; Howard, 1906; Hymenoptera: Aphelinidae ) nachgewiesen, wobei an den meisten Standorten A. diaspidis dominierte. Die Parasitierungsraten durch beide Arten schwankten zwischen 1,9 und 23,0 %. Als Prädator wurde der Nierenfleckige Kugel-/Marienkäfer ( Chilocorus renipustulatus , Scriba, 1790) beobachtet. Antagonists of the white scale ( Pseudaulacaspis Pentagona, Targioni-Tozzetti, 1886) were determined from peaches and sweet cherries as host plant at the orchards of the Centre for Agriculture and Technology Augustenberg (LTZ) in 2009 and 2010 as well as from four other commercial red and black currant orchards in Baden-Wuerttemberg in 2010. The study focused mainly on the parasitoid species of P. Pentagona as well as the rate of parasitism of white scale caused by these parasitoids using emergence traps with invested branch samples of the different host plants in the laboratory. Beside the parasitoids, possible predators of the white scale were observed in the field in 2010 at the orchard of the LTZ. The two parasitic wasp species Aphytis diaspidis and Encarsia berlesei (Howard, 1881 and 1906) were determined as parasitoids of the white scale, whereas A. diaspidis was dominant at most sites. Rate of parasitism caused by both species ranged from 1.9 to 23.0%. The Kidney-Spot Ladybird Beetle ( Chilocorus renipustulatus, Scriba, 1790) could be observed as a predator of the white scale in the field.

  • The distribution, host plants and natural enemies of white peach scale, Pseudaulacaspis Pentagona (Targioni-Tozzetti) (Hemiptera: Diaspididae), in Ankara province.
    2016
    Co-Authors: Ehab Mohammed Ahmed Mahmood Mohammed, Selma Ülgentürk, Nedim Uygun, Antonio Pietro Garonna, Ferenc Szenkirály, Meral Fent, Mohammed Hayat
    Abstract:

    The distribution, host plants, and natural enemies of the white peach scale, Pseudaulacaspis Pentagona (Targioni-Tozzetti) (Hemiptera: Diaspididae), were investigated in 25 districts of Ankara Province, Turkey, during 2013-2015. Thirteen districts were infested with harmful white peach scale; infestation was most common in parks, roadsides, private and institution gardens in centrum and old silkroad parts of Ankara. Twenty-two host plant species were found in these 13 districts, five of which (Aesculus carnea, Hibiscus sp., Paulownia tomentosa, Rhus thyphina and Salix babylonica) had not previously been recorded as host plants in Turkey. Some host plant species, including Catalpa bignonioides, Cornus alba, Fraxinus americana, F. excelsior, Forsythia intermedia, Morus alba, M. nigra and Sophora japonica, were found to be very highly infested. Five species of predators and three species of parasitoids were associated with white peach scale. Orius minutus L., Chrysoperla pallida (Henry et al.) are new record as predator of P. Pentagona in World and Epitetracnemus comis Noyes &Ren Hui are first time record in Turkey

  • Effect of three diaspididae prey species on development and fecundity of the ladybeetle Chilocorus bipustulatus in the laboratory
    Biocontrol, 1998
    Co-Authors: Nedim Uygun, N.z. Elekçioğlu
    Abstract:

    The purpose of this investigation was to determine the most suitable prey for the development and fecundity of the predatory coccinellid, Chilocorus bipustulatus (L.) on three different diaspidid species: Aspidiotus nerii Bouche, Aonidiella aurantii (Maskell), and Pseudaulacaspis Pentagona (Targioni-Tozzetti). Life tables were constructed at constant 25°C and the developmental time, longevity, fecundity, and the sex ratio were determined. Individuals fed with A. nerii displayed the shortest larval and pupal developmental time (26.0 days), lowest immature mortality rate (16.6%), highest net reproduction rate (264.7 females/ female), shortest generation time (72.9 days), and the highest intrinsic rate of increase (0.077 females/female/day). The results showed that under laboratory conditions C. bipustulatus developed best on A. nerii.

  • Studies on the effects of some pesticides on white peach scale, Pseudaulacaspis Pentagona (Targ.-Tozz.) (Homoptera: Diaspidae) and its side-effects on two common scale insect predators
    Crop Protection, 1997
    Co-Authors: L.bakircioğlu Erkiliç, Nedim Uygun
    Abstract:

    Abstract Studies were carried out on chemical control of white peach scale (WPS), Pseudaulacaspis Pentagona (Targ.-Tozz.) (Hom.: Diaspidae), the main pest of peach in the East Mediterranean region of Turkey in 1992 and 1993. The effectiveness of two insect growth regulators, summer oil, methidathion, and summer oil + a reduced dosage of methidathion were evaluated under field conditions. The side-effects of the same pesticides on the predators Chilocorus bipustulatus (L.) (Col.: Coccinellidae) and Cybocephalus fodori minor (Endrody-Younga) (Col.: Cybocephalidae) were examined under laboratory conditions. Buprofezin gave sufficient control of WPS in the field experiments and had only limited side-effects on WPS-predators in the laboratory. Moderate WPS-populations were successfully controlled by fenoxycarb and summer oil. The side-effects of these pesticides were comparable to those of buprofezin. Methidathion with and without summer oil is able to suppress WPS-populations, but should not be used in integrated pest management programmes because of high toxicity towards WPS predators.

  • scale insect biology and behaviour poster abstract observations on the population development of Pseudaulacaspis Pentagona hemiptera coccoidea diaspididae under semi field conditions in the east mediterranean region of turkey
    Entomologica, 2016
    Co-Authors: L. B. Erkiliç, N. Uygun
    Abstract:

    Populations of Pseudaulacaspis Pentagona (Targioni Tozzetti) were observed on naturally infested young peach trees (cv. ‘June Gold’), kept in 2x2x2m cages covered in cheese cloth under semi-field conditions. Overwintering adult females were marked (1x2.5cm) on the plants with special glue (Tangle Trap). Both the number of crawlers produced by each female and the duration of each development stage were recorded. In each generation, 35 females were observed. P. Pentagona had four generations a year and the first crawlers appeared from overwintered females at the beginning of April. The first generation was completed in May, the second in July, the third in August and the fourth in September. The duration of each generation was found to vary significantly in relation to temperature, with the first generation taking the longest (71.6 days) and the second generation the shortest (61.2 days). The number of crawlers produced by each generation was also found to vary significantly. The greatest number of crawlers (99.4 crawlers per female) was produced by the overwintering females and the lowest number of crawlers (17.9 crawlers per female) by the fourth generation.

  • Development time and fecundity of the white peach scale,Pseudaulacaspis Pentagona, in Turkey
    Phytoparasitica, 1997
    Co-Authors: L. B. Erkiliç, N. Uygun
    Abstract:

    The white peach scale (WPS), Pseudaulacaspis Pentagona (Targioni-Tozzetti) (Homoptera: Diaspididae), is a worldwide polyphagous scale insect. It is widely distributed in Turkey, where it is the main pest of peach trees. The development and fecundity of P. Pentagona were examined at different temperatures and on different hosts in the laboratory; from these data, life tables were constructed and intrinsic rates of increase were calculated. The longevity of WPS decreased with a rise in temperature. At 25°C the largest number of crawlers (76.1 crawlers/female) was observed. The development time of WPS was generally longer on peach than on squash or potato; fecundity was higher on potato than on the other hosts, potato tubers and peach trees.
