Gall-Inducing Wasps of the Genus Diplolepis (Hymenoptera: Cynipidae) on Shrub Roses of Turkey

Abstract Five species of gall-inducing Diplolepis are reported from Rosa spp. in Turkey - D. eglanteriae (Hartig), D. fructuum (Rübsaamen), D. mayri (Schlectendal), D. rosae (Linnaeus), and D. spinosissimae (Giraud). The most abundant gall is that induced by D. fructuum which is often considered a pest of the rose industry because it can completely destroy the hips. In some areas, up to 90% of the hips are infested by galls of D. fructuum. Diplolepis eglanteriae, D. mayri, D. spinosissimae, and D. rosae induce galls on the leaves, but are uncommon and not considered pests. The importance of Turkey as a midpoint between Europe and Asia in the distribution of roses and Diplolepis is discussed. The inducer responsible for hip galls in Turkey previously identified as D. mayri is reported here as D. fructuum.

Note: Life history ofLixus bardanae on curly dock (Rumex crispus) in Turkey

The biology ofLixus bardanae (F.) (Coleoptera: Curculionidae) on curly dock (Rumex crispus L.) in northeastern Anatolia (Bayburt, Erzurum and Kars Provinces), Turkey, was studied during the years 2000 and 2001.L. bardanae completes one generation in a year, overwintering as an adult. It feeds on leaves of the host plant. Females lay eggs individually into stems and the young larvae create galleries in stems while feeding. Pupation occurs inside stems in cells fashioned from frass. In late September, adults move into soil and overwinter in an upright position around the roots of the host plant. Infestation levels were found to range between 34% and 84%. Two parasitoids,Exeristes roborator F. andEndromopoda phragmitidis Perve (Hymenoptera: Ichneumonidae), were reared fromL. bardanae.

An integrative approach in the assessment of species delimitation and structure of the Merodon nanus species group (Diptera: Syrphidae)

The Merodon nanus group (Diptera, Syrphidae) is a small group of closely related species with high morphological similarity. Until now, based on morphological characters, this group consisted of five species: M. nanus Sack, 1931; M. telmateia Hurkmans, 1987; M. kopensis Vujić et Hayat, 2015; M. neonanus Vujić et Taylor, 2015; and M. rasicus Vujić et Radenković, 2015. Here, using an integrative approach based on molecular characters (sequences of the D2–3 region of the nuclear 28S rRNA gene and the mitochondrial COI gene) and data obtained from geometric morphometry of wing shape, we distinguish all five previously morphologically defined species of the group. Additionally, we identify one species as being new to science, M. vladimiri Vujić et Kočiš Tubić sp. n. We emphasize the separation of this newly described species according to the sequences obtained from the slowly evolving 28S rRNA gene, which demonstrated four to five mutation positions between this species and morphologically the most similar M. neonanus species. Also, our results show a clear division of M. telmateia into at least three population groups that we designate as the subspecies: M. telmateia mediterraneus Ačanski et Kočiš Tubić subsp. n. and M. telmateia samosensis Ačanski et Kočiš Tubić subsp. n. exhibiting western distributions (western Anatolia and the Greek island of Samos, respectively) and the nominative subspecies M. telmateia telmateia with an eastern Anatolian distribution.

İran’ın Doğu Azerbaycan İli Mekidi Vadisi syrphid türleri (Diptera: Syrphidae)

Syrphid fauna of Mekidi valley in Iran was studied during 2008- 2009. The specimens were collected using malaise trap as well as common entomological net in eighteen. Among of 274 collected specimens, 38 species belonging to 20 genera and two subfamilies were verified that all of them are as new records for studied region and a species, Chrysogaster virescens Loew, 1854, is a new record for the Iranian insect fauna.

Circulifer haematoceps, Stenometopiellus angorensis ve Doratura exilis (Homoptera: Cicadellidae)’in Bazı Mera Kalite Faktörleriyle İlişkisi / Relationships of Circulifer haematoceps, Stenometopiellus angorensis and Doratura exilis (Homoptera: Cicadellidae

OZET: Cicadellidae (Homoptera) turlerinin mera kalite faktorleriyle iliskisini belirlemek amaciyla, 2001 yilinda Erzurum Merkez, Ilica, Askale ve Cat ilcelerindeki meralarda 86 noktada yurutulen calismada, toplam 34 tur belirlenmistir. Bunlardan, Circulifer haematoceps (Mulsant and Rey) 72 noktadan elde edilen 709 birey; Stenometopiellus angorensis (Zachvatkin) 51 noktadan 289 birey; Doratura exilis (Horvath) ise 36 noktadan 212 birey ile en yaygin turlerdir. Her survey noktasindan toprak ornekleri alinmis, koye uzaklik, taslilik, egim, otlatma, rakim, erozyon ve toprak derinligi gibi ozellikleri kaydedilmistir. Bu alanlarda bulunan birey sayisi ile mera kalitesini belirleyen faktorlerden koye uzaklik, taslilik, egim, otlatma, rakim, erozyon ve toprak derinligi arasindaki iliskiler incelenmistir. Buna gore, C. haematoceps yogunlugu ile otlatma arasinda olumsuz cok onemli, rakim arasinda ise olumlu cok onemli iliski (P<0,01); S. angorensis ve D. exilis turlerinde ise bocek yogunlugu ile otlatma arasinda olumsuz onemli iliski (P<0,05) belirlenmistir. Korelâsyonda dogrudan ve dolayli etkisi olan degiskenlerden onemli olanlarin path katsayilari ve etki dereceleri tespit edilmistir. Anahtar Kelimeler: Circulifer haematoceps, Stenometopiellus angorensis, Doratura exilis, mera kalite faktorleri ABSTRACT: This study was conducted in the rangelands of Erzurum Center, Ilica, Askale and Cat districts to determine Cicadellidae (Homoptera) species and their relationships with some rangeland quality factors in 2001. During the surveys in 86 areas, totally, 34 species were determined. Among these species, Circulifer haematoceps (Mulsans and Rey) with 709 specimens from 72 localities; Stenometopiellus angorensis (Zachvatkin) with 289 specimens from 51 localities; Doratura exilis (Horvath) 212 specimens from 36 localities were found as most widespread species. The soil samples were taken from each survey area, and distance to village, stony, slope, grazing, altitude, erosion and depth of soil were recorded. Relationships between the number of specimens in the research areas and some rangeland quality factors, distance to village, stony, slope, grazing, altitude, erosion and depth of soil, were studied. Analysis of the data revealed that negative very significant relationship between density of C. haematoceps and grazing, and positive very significant relationship between the insect density and altitude (P<0,01), and also positive significant relationship between the insect density of S. angorensis and D. exilis and grazing (P<0,05) were found. Variables having direct or indirect effects on the correlation and their path coefficients and effect degrees were determined through path analysis.
