The Betula aphids of Turkey

To date, about 400 aphid species have been recorded in Turkey (see References). However, this is the first paper which 3 aphid species determined in 3 genera on Betula spp. in Turkey. These species, namely Calaphis flava Mordvilko, Callipterinella calliptera (Hartig) and Euceraphis punctipennis (Zetterstedt) all belong to the family: Aphididae, subfamily: Myzocallinae, tribe: Calaphini and none of the species has previously been recorded in aphid fauna lists on Betula spp. in Turkey. Their synonyms, morphological characteristics and biological data, supported by literature, were also considered.

Aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) on weeds from Ankara, Turkey

Studies were conducted during the years 2001–2003 to determine the parasitoids of Aphidoidea (Homoptera) species on weeds in Ankara province. Six genera and ten species of aphid parasitoids belonging to Braconidae were determined. The tritrophic associations of plant/aphid/parasitoid were analyzed. Forty-four associations of aphidiinae wasps, host aphids and host plants new to the Mediterranean region and 71 new associations for Turkish fauna were reported. http://www.phytoparasitica.org posting July 14, 2005.     

First report of the parasitoid Aphelinus chaonia Walker, 1839 (Hymenoptera: Aphelinidae) in Algeria and its host aphid Takecallis arundicolens Clarke, 1903 in Africa

A survey of aphids and their parasitoids in some localities of Algiers from February 2017 to June 2018 detected the presence of Aphelinus chaonia Walker, 1839 for the first time in Algeria. This parasitoid was found on five aphid species: Hyalopterus pruni, Aphis craccivora, Aphis fabae, Aphis spiraecola and Takecallis arundicolens. The latter was found on the leaves of Bambusa sp. and reported for the first time in Algeria and also Africa. Data on the diagnosis and the bioecology of Aphelinus chaonia are also given in this paper.     

Note on <Emphasis Type="Italic">Wahlgreniella nervata</Emphasis> (Gillette, 1908) (Hemiptera: Aphididae): a new pest of Damask rose in Turkey

Alate viviparous females of Wahlgreniella nervata (Gillette) were found on a Damask rose (Rosa damascena Mill.) plantation in Isparta Province, Turkey. The aphid is recorded for the first time from Turkey. Besides, Damask rose is a new host for this species. Brief information about this aphid including a key to the alate females of aphid species known to infest Damask rose in Turkey is provided.     

Adaptation of native syrphid flies to new exotic plant (Impatiens spp.)-aphidant associations in Central Europe (Dipt., Syrphidae; Hom., Aphididae; Hym., Formicidae)

Impatiens parviflora andI. glandulifera, two invasive touchme-not species of exotic origin were found to be associated with two aphid groups in Central Europe: a) Exotic species subsequently following their invasive plant hosts (Impatientinum asiaticum Nevsky), b) native species secondarily adapted to the new exotic hosts (Aphis fabae cirsiiacanthoidis Scop.). The species number (listed) of associated syrphid flies in the newly developed guilds was rather high, consisting of broadly oligophagous species. The plant phenology and adaptation of the aphids have resulted in associations which apparently represent seasonally significant sources of prey, their importance apparently increasing with the decreasing season. Antattendance was determined in both aphid species, and no adverse interference with the preying syrphid larvae was observed. In spite of an overall classification of the target plants as expansive weeds, they are classified positively as contributing to the enhancement of syrphid fly populations in the biocorridors in the cultivated landscape.     

New aphid vectors and efficiency of transmission of Potato virus A and strains of Potato virus Y in the UK

The aphid‐transmitted viruses Potato virus Y (PVY) and Potato virus A (PVA) commonly affect seed potatoes in the UK. The transmission efficiency for aphid species is used to calculate a potential transmission risk and is expressed as a relative efficiency factor (REF). These REFs have not previously been calculated for UK strains of viruses or aphid clones. Using a previously published method, REFs have been calculated for the aphid species and viruses commonly occurring in UK potatoes. The efficiency of transmission of Myzus persicae is nominally set to a REF of 1 and REFs for other species are calculated relative to this. These data represent the first set of REFs calculated for PVA transmission. Macrosiphum euphorbiae (REF 0.91) was almost as efficient as M. persicae at PVA transmission. The data were further analysed to compare transmission rates of PVY and PVA using a binomial (logit) generalized mixed model to take into account the potential influence of variation in virus titre between leaves. This approach found that there is little variation between the efficiency of transmission between clones of each aphid species or between strains within a virus species. This is a first report that Aphis fabae, Metopolophium dirhodum, Sitobion avenae, Acyrthosiphon pisum and Cavariella aegopodii have the ability to vector PVA. This study also represents a first report that C. aegopodii has the ability to vector PVY and confirms the potential of S. avenae, A. fabae, M. euphorbiae and Rhopalosiphum padi as important PVY vectors.     

Status of invasive alien plants included in EPPO Lists in Turkey

Turkey is one of the richest areas in the middle latitudes in terms of plant diversity. It has approximately 12 000 plant species and a great number of new species are being added each year. However, invasive alien species have not yet been fully considered in Turkey and only two plant species are in Turkey's quarantine list (Arceuthobium spp. and Eichhornia crassipes). EPPO is an intergovernmental organization responsible for cooperation in plant protection in the European and Mediterranean region and maintains the A1 and A2 Lists of pests recommended for regulation (A1 species are absent from the EPPO region, A2 species are present but of limited distribution), the List of Invasive Alien Plants, the Observation List of invasive alien plants and the Alert List. Eichhornia crassipes, Heracleum persicum, Heracleum sosnowskyi, Ludwigia peploides, Polygonum perfoliatum and Solanum elaeagnifolium are among the species which were recorded in Turkey and are included in the EPPO A2 List. Species recorded in the EPPO List of invasive alien plants which are present in Turkey are: Acroptilon repens, Ailanthus altissima, Ambrosia artemisiifolia (= A. elatior), Carpobrotus edulis, Cortaderia selloana, Cyperus esculentus, Paspalum distichum (= P. paspalodes), Oxalis pes‐caprae and Sicyos angulatus. Azolla filiculoides and Rhododendron ponticum are listed in the EPPO Observation List of Invasive alien plants and Miscanthus sinensis, listed in the EPPO Alert List, are also recorded in the Turkish flora.

In a study carried out during 2002 and 2004 in Diyarbakıir and Mardin provinces, southeast Turkey, specimens were collected twice a month from cultivated and non-cultivated plants. Sixteen leafminer (Diptera: Agromyzidae) species were identified. Among them,Agromyza abiens Zetterstedt, 1848;Napomyza elegans (Meigen, 1830);Phytoliriomyza dorsata (Siebke, 1864); andPhytomyza aquilonia Frey, 1964 are new records for the Turkish leafminer http://www.phytoparasitica.org posting July 24, 2005.     

Contribution to the knowledge of the family Eulophidae (Hymenoptera: Chalcidoidea) from Turkey,with some new records

Data are presented on the occurrence of 51 species of the family Eulophidae in Turkey based on material obtained mainly from grass and leaves with leaf miners. The paper combines the faunistic and distributional data obtained from recent studies with all other species of the family known from Turkey up to now. The recorded genera (with the number of recorded species) are:Aprostocetus Westwood (20),Baryscapus Förster (8),Cirrospilus Westwood (2),Diglyphus Walker (5),Hyssopus Girault (2),Euplectrus Westwood (1),Hemiptarsenus Westwood (3),Necremnus Thomson (3),Pnigalio Schrank (2),Pronotalia Gradwell (1) andSympiesis Förster (4). Twenty-eight species are reported for the first time in the Turkish fauna.     

Aphid and host plant species in the Arava Valley of Israel: Epidemiological aspects

A survey of aphid species which colonize or reproduce on wild and cultivated plants in the Arava Valley of Israel was carried out at the end of winter 1986. Thirty-three aphid species were collected on wild plants and 23 in green tile or yellow traps exposed in cultivated plots. Aphids were recorded from 77 plant species in 22 botanical families.Myzus persicae, Aphis craccivora, Brachyunguis harmalae, Acyrthosiphon gossypii andAphis gossypii were present on plants in 19 botanical families. M. persicae was the most frequently trapped aphid species in both green tile and yellow traps. The possible origin of the aphid species found in the desert was considered in view of the ecology and geography of the region. The role of aphid species trapped in the Arava Valley, in the epidemiology of potato virus Y (PVY) and zucchini yellow mosaic virus (ZYMV), is discussed.

The aphid is recorded for the first time from Turkey. Brief information about the invasive yellow rose aphid, including its distribution in Isparta Province and a key to the apterous females of aphid species known to infest Damask rose in Turkey, is provided.     

Description ofPauesia (Pauesia)anatolica (Hymenoptera: Braconidae, Aphidiinae) sp. nov., a parasitoid of the cedar aphidCinara cedri

The first parasitoid species reared from a population of the cedar aphid,Cinara cedri Mimeur, 1935 (Hemiptera: Aphididae), from the peninsula of Anatolia in Turkey is described.Pauesia anatolica (Hymenoptera: Braconidae, Aphidiinae) is closely related to some species of thelaricis group ofPauesia from which it differs in the number of antenomers, the propodeum and features of the female genitalia. Its potential use as a natural enemy in areas where the aphid has been introduced is discussed. http://www.phytoparasitica.org posting Aug. 28, 2005.     

Contribution to the knowledge of the families apionidae and nanophyidae (Coleoptera: Curculionoidea) from Turkey, with new records

Data are presented on the occurrence of 43 species of the family Apionidae and two species of the family Nanophyidae in Turkey based on the material obtained mainly by beating stone-fruit trees in NE Turkey. The identity and information about the three species of Apionidae —Squamapion sp.cf.bifarium (Balfour-Browne),Protapion sp.cf.ruficrus (Germar),Catapion sp.cf.seniculus (Kirby) — must be revised. The faunistic data in the present paper on almost all species add to prior knowledge on their distribution in Turkey.Hypophyes aphyllae (Peyerímhoff),Ceratapion kasbekianum (Gerstaecker),Squamapion ottonis (Wagner),S. samarense (Faust),S. phocopus (Eppelsheim),Taeniapion rufulum (Wencker),Pseudoprotapion astragali (Paykull),P. ergenense (Becker),Stenopterapion intermedium (Eppelsheim) andOxystoma fausti (Desbrochers) are reported for the first time in the Turkish fauna. http://www.phytoparasitica.org posting Nov. 8, 2001.     

柑橘衰退病毒含量对其蚜传效率的影响

为明确毒源植株和蚜虫中柑橘衰退病毒(Citrus tristeza virus,CTV)的发生情况与蚜虫传播CTV能力的关系,将褐色橘蚜、棉蚜、橘二叉蚜和绣线菊蚜置于分别感染了4个CTV分离株的锦橙上取食24 h后,运用巢式RT-PCR和实时RT-PCR检测蚜虫和锦橙的带毒情况,并分析蚜虫的传毒能力。结果显示,蚜虫中CTV的平均带毒率为0.76~0.84,其中棉蚜的最高,其次为绣线菊蚜、褐色橘蚜和橘二叉蚜。锦橙中各CTV分离株的含量差异不大,与蚜虫传毒效率间无显著相关性;也未发现蚜虫带毒率与其传播CTV能力之间存在相关性。蚜虫体内CTV的含量为5.36×103±2.33×103~2.01×106±3.67×105拷贝,褐色橘蚜中含量最高,其次为棉蚜、橘二叉蚜和绣线菊蚜;且高蚜传能力CTV分离株在褐色橘蚜体内的含量远高于低蚜传能力分离株。表明蚜虫体内CTV的含量可能与蚜虫传毒能力有关。     

The grapevine aphid Aphis illinoisensis: a good example of recent invasion and rapid colonization by aphids

Aphis illinoisensis represents one of the most recent aphid invaders from the New World to the Mediterranean Region. This aphid, which is native to North America and is now widely distributed in Central and South America, was first found in Southern Turkey in 2002, and in 2005 it was also found in Crete (Greece). Thereafter it was recorded from Northern Cyprus, Israel, Tunisia, Algeria, Montenegro and Libya, and is now probably present throughout the Mediterranean. The present work provides data on the presence of this aphid in the Maltese islands, a group of low‐lying islands situated in the central Mediterranean Basin.     

Note:Cnaemidophorus rhododactyla, a NewRosa spp. Pest for Turkey, and its new parasitoids, a NewRosa spp. Pest for Turkey, and its new parasitoids

In the present study,Cnaemidophorus rhododactyla (Denis & Schiffermüller) (Lepo Pterophoridae) was noted for the first time as a pest ofRosa spp. in Turkey. The larva ofC. rhododactyla makes a cavity by feeding in the flower-bud and destroys at least 60% of the mass of the flower-bud. There are approximately 12 species ofRosa in Erzurum and Kars provinces, butRosa dumalis Bechst. andR. subcanina L. suffered more damage than the otherRosa species. One species of Tachinidae (Diptera) —Pseudoperichaeta palesoidea (Robineau-Desvoidy), and two species of Ichneumonidae (Hymenoptera) —Sinophorus turionus (Ratz.) andScambus brevicornis Gravenhorst, were reared as larval parasitoids ofC. rhododactyla. C. rhododactyla is a new host record for these parasitoids. Additionally,S. turionus is a new record for the Turkish fauna.
