Pseudaulacaspis pentagona targioni-tozzeti (Hemiptera: Diaspididae)’nın Ankara ilindeki yayılışı konukçuları ve dut üzerindeki biyo-ekolojisi

Dut kabuklubiti Pseudaulacaspis pentagona Targioni-Tozzetti (Hemiptera:Diaspididae), Turkiye’de onemli bir dut zararlisi olup, tas cekirdekli meyvelerde deekonomik zarar sebep olmaktadir. Polifag bir zararli olmasi nedeniyle, sus ve ormanbitkilerinde de gorulmektedir. Son yillarda Dut meyvesine artan talep nedeniyle, dutyetistirme alanlari artmis, dolayisiyla dut kabuklubiti onemli bir zararli haline gelmistir.Bu calismada Dut Kabuklubiti’nin Ankara Ili sinirlari icindeki yayilisi, konukculari,dogal dusmanlari ve biyo- ekolojisi incelenmistir. Arastirma cercevesinde Ankara’nin25 ilcelerine 2014-2015 yillarinda surveyler duzenlenmistir. Bu 25 ilceden sadece 13ilce’nin P. pentagona ile bulasik oldugu tespit edilmistir. P. pentagona’nin Ankara’da23 tur sus ve park bitkisinde yaygin ve zararli oldugu saptanmistir. Bunlardan M. albauzerinde ozellikle Ayas ilcesinde ekonomik zararli oldugu gozlenmistir. Biyo- ekolojicalismalari 2013-2015 yillari arasinda P. pentagona’nin ekonomik Dut zararlisi olduguAyas, sus bitiklerinde zararli oldugu Altin Park (Altindag), Botanik Park (Cankaya) veCemre Park (Demetevler)’da secilen 5’er Dut agacinda yurutulmustur. Calismasonucunda P. pentagona’nin kisi dollenmis disi olarak gecirdigi ve dol sayisi 2 – 3arasinda degistigi saptanmistir. Ilk yumurtalarin ve hareketli nimf genellikle Mayisbasinda, Temmuz sonunda ve Eylul basinda saptanmistir. Erkek ucuslarinin Temmuzortasinda, Agustos sonunda ve Ekim sonunda tespit edilmistir. Ankara’da bes avci turve uc tur parazitiot P. pentagona’nin yaygin dogal dusmanlari olarak tespit edilmistir.Avci turler; Chilocorus bipustulatus L., Brumus quadripustulatus L., (Coleoptera:Coccinellidae), Cybocephalus sp. (Coleoptera: Cybocephalidae), Orius minutus L.,(Hemiptera: Anthocoridae), ve Chrysoperla pallida (Henry vd.) (Neuroptera:Chrysopidae)’dir. Parasitoit turler; Aphytis proclia (Walker), Encarsia berlesei(Howard) (Hymenoptera: Aphelinidae) ve Epitetracnemus comis Noyes & Ren Hui(Hymenoptera: Encyrtidae) dir.AbstractPseudaulacaspis pentagona Targioni-Tozzetti (Hemiptera: Diaspididae), is a major pestof mulberry in Turkey and causes economic damage in stone fruits beside of ornamentaland forestry plants. The distribution of P. pentagona were investigated in 25 districts ofAnkara during 2013–2015. Thirteen districts were infested with mulberry scale.Twenty-three host plants species were found in these 13 districts. One of these hostplant was M. alba especially in Ayas district P. pentagona was observed as economicpests of Mulberry.The biyology of the mulberry scale was carried out between 2013-2015 on selected 5trees of mulberry as a host plant of P. pentagona wich it’s very harmful pest ofmulberry trees in Ayas, AltinPark , Botanik Park and Cemre Park. In this study wasfound P. pentagona spent the winter as fertilized females and it has 2 or 3 generations inthe year. Also found that the eggs were hatch in the beginning of May, end of July andfirst week of September. Males flights were started in mid-July, late August and at theend of October. Five species of predators and three species of parasitoids were found tobe associated with the mulberry scale. The predators, Chilocorus bipustulatus L.,Brumus quadripustulatus L., (Coleoptera: Coccinellidae), Cybocephalus sp.(Coleoptera: Cybocephalidae), Orius minutus L. (Hemiptera: Anthocoridae), andChrysoperla pallida (Henry vd.) (Neuroptera: Chrysopidae), and the parasitoids Aphytisproclia (Walker), Encarsia berlesei (Howard) (Hymenoptera: Aphelinidae) andEpitetracnemus comis Noyes & Ren Hui (Hymenoptera: Encyrtidae).
