Turkish Journal of Zoology
Eriophyoid mites are recognized as the second most economically important group among the Acari following spider mites. The identification of eriopyhoid mites traditionally based on morphological characters. However, the size of these diagnostic structures is very small and this often causes misidentification of species. In this study, we used DNA-based identification for five eriophyoid species collected from the Thrace region of Turkey (Aceria erinea, Rhyncaphytoptus ficifoliae, Eriophyes pyri, Aceria massalongoi, Colomerus vitis collected from Juglans regia L., Ficus carica L., Pyrus communis L., Vitex-agnus castus L., Vitis vinifera L., respectively) using both cytochrome oxidase subunit I (MW396744-MW396748) and 28S rRNA …

Status And Distribution Of The Striped Hyaena, Hyaena Hyaena, In Turkey: An Updatedassessment (Carnivora: Mammalia), Mühsi̇n Çoğal, Yasi̇n İlemi̇n, Mustafa Sözen
Turkish Journal of Zoology
The Striped Hyaena, Hyaena hyaena, extends its distribution in the north into Turkey, where it has always been rare. In a status assessment conducted by Kasparek et al. in 2004, it was shown that the species is at the brink of extinction. We compiled information from different sources including a press survey and camera trapping in different parts of the country. The situation has even deteriorated since then. The population has strongly decreased, in particular, in the Marmara and Mediterranean regions, and presently the species survives in Western Anatolia only in some small relict populations in Manisa, İzmir, Muğla, and …

Turkish Journal of Zoology
Vineyards face several biotic threats that compromise the grape quality and quantity. Among those that cause relevant economic impact and have worldwide distribution are the oomycete Plasmopara vitícola, the fungi Erysiphe necator and Botrytis cinerea, and the arthropods Lobesia botrana, Tetranychus urticae, and Phylaenus spumarius (principal vector of the bacterial disease Xylella fastidiosa in Europe). Their management relies primarily on agrochemicals with short persistence; widespread use of these chemicals causes environmental and human health problems. The challenge of sustainable viticulture is to provide ecologically sound alternatives. In this regard, the application of entomopathogenic nematodes (EPNs) and natural products derived from …

The Lure Of Hidden Death: Development Of An Attract-And-Kill Strategy Against Wireworms Combining Semiochemicals And Entomopathogenic Nematodes, Diana La Forgia, Pamela Bruno, Raquel Campos-Herrera, Ted Turlings, Francois Verheggen
Turkish Journal of Zoology
Wireworms are polyphagous soil-dwelling pests that are hard to control. Attract-and-kill strategies, combining attractive semiochemicals with biocontrol agents, have great promise to control insect pests. We hypothesized that the combination of plant semiochemicals and entomopathogenic nematodes (EPNs) in an attract-and-kill system could greatly enhance the nematodes' efficiency against wireworms. We evaluated the potential of alginate beads loaded with plant extracts and EPNs to control Agriotes obscurus. We tested the efficiency to kill wireworms or to reduce their feeding activity when combining potato tuber extracts as attractants with any of seven different EPN populations. While a direct application of EPNs on …

Turkish Journal of Zoology
The Neotropical brown stink bug Euschistus heros and the green-belly stink bug Dichelops melacanthus are the most important pests today for the succession system of soy-corn in Brazil. Dichelops melacanthus attacks the emerging shoot (epicotyl) of corn plants at the seedling stage of their development, remaining and reproducing on the straw over generations. Euschistus heros, on the other hand, feeds directly on the grains and lodge under fallen leaves after the soybean harvest, due to the absence of another crop host. Entomopathogenic nematodes (EPNs) are capable of killing insects due to their ability to search for the host in the …

Third and fourth instar larvae of Aedes aegypti actively ingested entomopathogenic nematodes (EPNs) and their symbiotic bacteria, resulting in larval mortality. All six EPN species evaluated in this study were pathogenic to Ae. aegypti but varied significantly in their virulence. Heterorhabditis bacteriophora and Steinernema carpocapsae were most virulent, H. megidis and S. kraussei showed the least virulence, whereas H. downesi and S. feltiae had intermediate virulence. Larval mortality was dose dependent for all EPN species. When using a dose of 100 infective juveniles (IJs) per larva, H. bacteriophora and S. carpocapsae caused 90%-100% mortality, whereas H. downesi and S. feltiae …

The efficacy of both botanical pesticides and entomopathogenic nematodes (EPN) is largely dose-dependent and driven by environmental conditions. Combination of the EPNs and botanicals may enhance their efficacy; thus, we investigated the compatibility of the medicinal plants Alepidea amatymbica and Elephantorrhiza elephantina with five locally isolated EPN strains, three Steinernema (S. khoisanae, S. biddulphi and S. innovationi) and two Heterorhabditis (H. bacteriophora and Heterorhabditis sp. SGI 244). The experiments were designed to evaluate EPNs survival in plant extracts extracted using water and ethanol at 1%, 0.75%, 0.50%, 0.25% and 0.125% concentrations and nematode viability post-exposure.

The rose sawfly, Arge rosae L. (Hymenoptera: Argidae), is one of the most destructive pests of roses grown both indoors and outdoors in Antalya province (south-western part of Turkey). Especially in greenhouse rose cultivation, growers depend heavily on synthetic pesticides to control this pest along with other arthropod pests in their crops. The aim of this study was to evaluate biocontrol potential of some indigenous soil-borne entomopathogenic fungi (EPF) against the pest. In pathogenicity assays, a total of 17 EPF isolates, belonging to three species [Beauveria bassiana (Bals.) Vuill. - 14, Clonostachys rosea (Link) Schroers - 2 and Isaria farinosa …

Freshwater ecosystems have a greater value for biodiversity per surface area than terrestrial and marine ecosystems. Streams and lakes are notably prone to biodiversity loss, being the greatest threats habitat destructions and nonnative species. The aim of the present study is to assess the fish composition of lotic and lentic water systems of an island ecosystem (Gökçeada Island, Turkey), which is poorly studied, and to highlight the entry routes and possible impacts of translocated fish species in an island ecosystem. The field surveys were conducted in a total of 14 sampling sites (five reservoirs and nine streams) in the inland …
