New records of Ichneumonidae (hymenoptera) species from Turkey

In this study, six Ichneumonidae species were recorded for the first time in Turkey:Tromatobia ornata (Gravenhorst, 1829) andStronyglopsis abdominalis Kasparyan, 1974 (Pimplinae);Tryphon auricularis Thomson, 1883 andThibetoides acerbus Viktorov, 1964 (Tryphoninae);Pion crassipes Homgren, 1857 (Ctenopelmatinae); andTemelucha tricolorata (Sedivy, 1968) (Cremastinae). The faunistic and distributional data notes are given for each species.     

Sources of resistance to ascochyta blight in wild Cicer species

Ascochyta blight [Ascochyta rabiei (Pass.) Lab.] is the major foliar disease of chickpea (Cicer arietinum L.). In search of better sources of resistance to ascochyta blight, 201 accessions of 8 annual wildCicer species were evaluated in field and greenhouse for 3 years (1988 to 1991) at Tel Hadya, Syria. One accession each ofC. judaicum Boiss (ILWC 165) andC. pinnatifidum Jaub. & Spach. (ILWC 159) were consistently rated resistant in both field and greenhouse evaluations. Another three accessions ofC. judaicum (ILWC 61, ILWC 154, ILWC 199) and six accessions ofC. pinnatifidum (ILWC 78, ILWC 88, ILWC 155, ILWC 160, ILWC 162, ILWC 203) were resistant or moderately resistant. The blight-resistant accessions ofC. judaicum originated from Jordan, Lebanon, Syria, and Turkey; and those ofC. pinnatifidum from Syria and Turkey. None of the accessions ofC. bijugum, C. chorassanicum, C. cuneatum, C. echinospermum, C. reticulatum andC. yamashitae were resistant to blight.     

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.     

First record of the tobacco flea beetle Epitrix hirtipennis Melsheimer [Coleoptera: Chrysomelidae: Alticinae] in Russia

The invasive pest of tobacco Epitrix hirtipennis (Melsheimer, 1847) is recorded in Russia for the first time. In April 2013 two specimens were collected in Sochi and in May one specimen was collected in Tuapse (near the Black Sea shore, in the Northern Caucasus). Epitrix hirtipennis is native to North and Central America. It was first recorded in the EPPO region in 1983 in Italy. It was subsequently recorded in the Azores (Portugal), Greece, Turkey, FYR of Macedonia, Bulgaria, and Syria. Epitrix hirtipennis is the first known alien flea beetle in Russia.     

The environmental and socio‐economic impacts of Eichhornia crassipes in the Victoria Falls/Mosi‐oa‐Tunya World Heritage Site,Livingstone, Zambia1

The exotic water hyacinth (Eichhornia crassipes) has invaded the Maramba River, a tributary of the Zambezi River in the Victoria Falls World Heritage Site in Zambia presenting several negative environmental and economic impacts. The major impacts identified by recent studies are on the generation of hydro electric power, tourism development, native biodiversity, fish catches and human health. Other recorded impacts are reduced quality and quantity of water for domestic use, restricted navigation of waterways and the threat posed to vital infrastructure. This has led to the initiation of efforts to manage this infestation and address the resultant impacts. Methods proposed for control of water hyacinth in the Victoria Falls/Musi‐oa‐Tunya Pilot Site are an integration of mechanical and biological control measures. This paper discusses the impacts of water hyacinth invasion on the Maramba River and isolated clusters on the backwaters of the Zambezi. Two field surveys undertaken over the last three years and recent interviews with resource persons representing interested and affected institutions and local communities impacted by water hyacinth provide the basis for the data in this paper and the current intervention activities. The field surveys and questionnaires targeted government institutions involved in the management of the area and persons from the private sector engaged in tourism activities. Local peoples found in and around the project area were also interviewed. A pioneering effort is made to quantify the impacts and detail the costs arising from these impacts. Recommendations for the future control and management of E. crassipes are also made.     

Parasitoids on codling moth Cydia pomonella (Lepidoptera: Tortricidae) in apple and walnut orchards in Syria

A survey was performed between 2007 and 2013 to investigate the complex of parasitoids on Cydia pomonella (codling moth) in apple and walnut orchards in Syria. This study showed the presence of 17 species belonging to 7 families from two orders (Hymenoptera and Diptera). The families Ichneumonidae and Braconidae were most common, comprising 8 and 4 species, respectively. Mastrus ridibundus and Neoplectops pomonella were new records for Syria.     

First record of fall armyworm (Spodoptera frugiperda) in Syria

The fall armyworm Spodoptera frugiperda is a lepidopteran pest that can damage and destroy a wide variety of crops. It is widely present in the Americans and has been invasive in Africa since 2016. Larvae of S. frugiperda were found for the first time in four rural farms on maize plants (Zea mays) located in Tafas town (Dara’a Governorate, in the south‐west of Syria) in November 2020. Infested maize showed the typical damage symptoms caused by S. frugiperda. Furthermore, morphological identification of larvae based on standard parameters of larvae confirmed the identity of the pest as fall armyworm. Considering the recent introduction of the pest into the EPPO region, it could be concluded that the pest probably entered Syria through natural spread (active flight and via wind currents) from Jordan, which borders Syria in the southern part and where the pest was found very recently.     

First report of the lacebug Corythauma ayyari (Drake) (Hemiptera: Tingidae) on Jasminum grandiflorum L. and Jasminum sambac (L.) from Syria

In Syria, defoliation was noted on several Jasminum grandiflorum and Jasminum sambac plants in various gardens in Latakia City and countryside in 2017. Subsequently, several male and female specimens of a lacebug insect were collected from the white jasmine, Jasminum grandiflorum, planted in the garden of the Latakia Center for Agricultural Research during 2018. Collected material was examined and identified as Corythauma ayyari (Drake). Infestation by this insect is considered by the authors to cause the defoliation of jasmine plants in Latakia City and it is reported to occur in Syria for the first time.     

Report of a pest risk analysis for Platypus parallelus (Fabricus, 1801) for Turkey

Invasive bark and ambrosia beetles (Curculionidae: Scolytinae and Platypodinae) are increasingly responsible for damage to forests, plantations and orchards worldwide. They are usually closely associated with fungi, which may be pathogenic causing tree mortality. Stressed or weakened trees are particularly subject to attack, as is recently felled, non‐treated wood. This PRA report concerns the ambrosia beetle Platypus parallelus (Euplatypus parallelus, Fabricus, 1801) (Coleoptera: Scolytidae), which was detected in official controls. The PRA area is Turkey. P. parallelus is not on the A1 or A2 list for Turkey but the Regulation on Plant Quarantine (3 December 2011‐OJ no: 28131) Article 13 (5) indicates that pests which are assessed to pose a risk for Turkey following PRA that are not present in the above lists and plants, wood, plant products and other materials contaminated by these organisms are banned from entry into Turkey. This risk assessment follows the EPPO Standard PM 5/3(5) Decision‐support scheme for quarantine pests and uses the terminology defined in ISPM 5 Glossary of Phytosanitary Terms. This paper addresses the possible risk factors caused by Platypus parallelus (Euplatypus parallelus, Fabricus, 1801) in Turkey.     

Scale insect species (Hemiptera: Coccoidea) in Syria

Scale insects in Syria were surveyed between 2009 and 2015. This study showed that Diaspididae and Coccidae were the most common families, comprising 5 and 8 species, respectively. The remaining families found comprised 1 species each. New records of Coccoidea fauna from Syria were Parlatoria blanchardi, Phoenicococcus marlatti, Coccus hesperidum, Coccus pseudomagnoliarum and Chionaspis etrusca.     

Herbicidal potential of allelochemicals from Lantana camara against Eichhornia crassipes and the alga Microcystis aeruginosa

In the field, the growth of the aquatic weed Eichhornia crassipes and the alga Microcystis aeruginosa may be inhibited by fallen leaves of Lantana camara. This study showed that extracts of L. camara leaves and their fractions reduced the biomass of E. crassipes and M. aeruginosa within 7 days under laboratory conditions. Two fractions with highly inhibitory activity from the extract were isolated and subsequently identified as the pentacyclic triterpenoids, lantadene A and lantadene B. Both compounds significantly inhibited E. crassipes and M. aeruginosa growth, even at a low concentration. At all concentrations tested, their inhibitory activities were much higher than that of salicylic acid, a putative allelochemical from L. camara. The results indicated that the predominant allelochemicals involved in L. camara against either E. crassipes or M. aeruginosa are not phenolic acids, but lantadene A and lantadene B. Field trials showed that released levels of lantadene A and lantadene B were significantly correlated with amounts and decomposition periods of L. camara leaves floated in water. The amount released from 5 kg L. camara leaves was over the inhibition threshold of both E. crassipes and M. aeruginosa and reached a maximum at days 15–20. This study suggested that allelochemicals of L. camara could potentially be used to improve the management of weeds and algae in aquatic systems.     

Random amplified polymorphic DNA markers reveal low genetic variation and a single dominant genotype in Eichhornia crassipes populations throughout China

Genetic variation within and between 34 populations of Eichhornia crassipes (water hyacinth) in China was surveyed using random amplified polymorphic DNA (RAPD) markers. A total of 1009 individuals were analysed, for which 12 RAPD primers amplified 69 reproducible bands, with 22 (32%) being polymorphic. The percentage of polymorphic loci (p) within a population ranged from 4.4% to 17.4%, and the mean Nei's gene diversity (H_e) was 0.046 ± 0.0145, indicating a low genetic diversity of E. crassipes in China. Each population contained at least four RAPD phenotypes (genotypes), and the same particular genotype was invariably dominant in all the populations sampled. The mean proportion of distinguishable genotypes was 0.29. Analysis of molecular variance revealed a large proportion of genetic variation (83.9%) residing within populations and a slightly larger proportion (88.1%) within localities, indicating a low genetic differentiation of E. crassipes populations, both locally and regionally. Human-mediated dispersal, vigorous clonal growth, and a generally low level of sexual reproduction were thought to be responsible for such a pattern of genetic structure.     

Nematodes of food legumes in the Mediterranean Basin1

Several endoparasitic nematodes have been reported on leguminous plants in the Mediterranean area. The most widespread are the root-lesion nematodes Pratylenchus mediterraneus, P. penetrans and P. thornei. Symptoms induced by these nematodes usually are not very impressive, but 50% yield loss of chickpea may occur. Among root-knot nematodes, Meloidogyne artiellia is associated with severe yield losses of chickpea in Italy, Spain and especially Syria. Tolerance limits of 0.14 and 0.02 of this nematode per ml soil are reported for winter and spring-sown chickpea, respectively. Meloidogyne incognita and M. javanica can be noxious to French bean and cowpea in sandy soil. The cyst nematode Heterodera goettingiana reduces yields of pea, broad bean and vetch when its population densities exceed 0.5, 1, and 2.1 eggs per g of soil, respectively. Heterodera ciceri occurs in northern Syria and Turkey and is responsible for economic yield losses of chickpea and lentil in fields infested with more than 1 or 2.5 eggs per g of soil, respectively. Pea and grass pea also suffer from infestation of this nematode. The stem and bulb nematode Ditylenchus dipsaci causes severe decline of broad bean, pea and probably lentil during wet seasons. Other nematodes, although present in moderate numbers, appear to have little importance.     

Low genetic diversity of Rhynchosporium commune in Iran,a secondary centre of barley origin

Rhynchosporium commune is a destructive pathogen of barley, causing leaf scald. Previous microsatellite studies used Syria as a representative of cultivated barley's centre of origin, the Fertile Crescent. These suggested that R. commune and Hordeum vulgare (cultivated barley) did not co‐evolve in the host's centre of origin. The present study compares R. commune populations from Syria with those from Iran, which represents a secondary centre of origin for barley at the eastern edge of the Iranian Plateau. Results from this study also suggest that R. commune and barley did not co‐evolve in the centre of origin of cultivated barley. This was evidenced by the low pathogen genetic diversity in Iran, which was even lower than in Syria, indicating that the pathogen may have been introduced recently into Iran, perhaps through infected barley seed. Hierarchical analyses of molecular variance revealed that most genetic diversity in Iran and Syria is distributed within populations, with only 14% among populations. Analyses of multilocus association, genotype diversity and mating type frequency suggest that Iranian populations reproduce predominantly asexually. The presence of both mating types on barley and uncultivated grasses suggest a potential for sexual reproduction. Rhynchosporium commune was also found on Hordeum murinum subsp. glaucum, H. vulgare subsp. spontaneum, Lolium multiflorum and, for the first time, on Avena sativa. The variety of wild grasses that can be infected with R. commune in Iran raises concerns of these grasses acting as evolutionary breeding grounds and sources of inoculum.

Note: Tachinid parasitoids (Diptera: Tachinidae) of<Emphasis Type="Italic">Mythimna (Acantholeucania) loreyi</Emphasis> in the southeast Anatolian region of Turkey

The loreyi leaf worm,Mythimna (Acantholeucania) loreyi (Duponchel) (Lepidoptera: Noctuidae), is a serious pest of gramineous crops and reduces yields in maize plantations. This study was undertaken to determine the tachinid parasitoid complex ofM. loreyi in the southeast Anatolian region of Turkey. Four tachinid species were found:Pseudogonia rufifrons (Wiedemann),Exorista larvarum (Linnaeus),Drino imberbis (Wiedemann) andLinnaemya neavei Curran were reared from field-collectedM. loreyi larvae. Of the four tachinid speciesM. loreyi is a new host record forE. larvarum andD. imberbis. L. neavei was recorded for the first time in Turkey and was the most frequently encountered parasitoid in this study. Total parasitism level was 7.1% in 2003 and 15.5% in 2004. http://www.phytoparasitica.org posting Jan. 16, 2007.     

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.     

Note: New records of flea beetle (Coleoptera: Chrysomelidae) from Turkey

Five species of flea beetles (Coleoptera: Chrysomelidae) were recorded for the first time in Turkey:Dibolia numidica Doguet,Longitarsus corynthius corynthius (Reiche et Saulcy),L. onosomae (Peyerimhoff),L. pulmonariae Weise andPhyllotreta ganglbaueri Heikertinger. The zoogeographical distribution of the species was reviewed. Among the species,L. onosmae andD. numidica have a limited distribution area in North Africa, and therefore their presence in Turkey is interesting. http://www.phytoparasitica.org posting July 14, 2004.     

A new pest on soybean in Turkey: Melanagromyza sojae Zehntner (Diptera: Agromyzidae)

Melanagromyza sojae Zehntner (Hemiptera: Agromyzidae) is known as a pest of several leguminous plants, especially Glycine max, soybean, in several countries worldwide. As a result of an alert raised by soybean producers in the province of Adana, which has a large share of soybean production in Turkey, plant samples in which pupae were observed were collected from two soybean fields in Çukurova in the production season in 2018. The samples were kept in the laboratory and the emerging adults were identified morphologically as M. sojae. Observations made in soybean fields in Turkey are presented. A review of the situation for this pest and its control methods are is presented. This is the first report of M. sojae in Turkey. It is therefore recommended to perform a close monitoring of this pest to investigate more in detail the extent of the damage caused by this pest in soybean crops in Turkey, to identify its variety preferences, other other hosts, natural enemies and control methods to be used.     

The current status of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiiidae) in Turkey and baseline toxicity of some insecticides

Tomato is one of the most important vegetable crops in Turkey, with national production of over 10 million tonnes in 2010. Tuta absoluta (Meyrick) is an important pest of tomato, and was first recorded in Urla District of Izmir Province in the Aegean region of Turkey in August 2009. It has since spread rapidly to the other regions of Turkey and become the main pest of tomato. Since its dispersal, chemical control has been the main method of control. Intensive use of insecticides has led to the development of resistance in T. absoluta. In this study, the baseline toxicity (LC₅₀ values) of some insecticides was determined using a leaf‐dip bioassay method in Antalya and Ankara populations of T. absoluta.
