This comprehensive checklist of aphids presents a total of 591 species, including 26 subspecies, from 147 genera belonging to 15 subfamilies in three families distributed over three superfamilies of Aphidomorpha recorded from 1903 to 2020 in Turkey. In the current list, the systematic positions with the genus and species names of some taxa have been revised, and some species have been downgraded to subspecies in accordance with recent changes in nomenclature. Seven species have been removed from the Turkish fauna and four species that were not included in the previous checklist have been added to the list. Also, 59 of the listed species (about 10% of Aphidomorpha) are evaluated as alien to the Turkish fauna, and the distribution of all species in Turkey is given.

In the present study, the natural enemies of aphids (Hemiptera: Aphididae) and their host plants including herbaceous plants, shrubs and trees were analysed to reveal their biodiversity and disclose tritrophic associations in different habitats of the South Marmara region of northwest Turkey. As a result of field surveys, 58 natural enemy species associated with 43 aphids on 58 different host plants were identified in the region between March of 2017 and November of 2018. In 173 tritrophic natural enemy-aphid-host plant interactions including association records new for Europe and Turkey, there were 21 representatives of the family Coccinellidae (Coleoptera), 14 of the family Syrphidae (Diptera) and 15 of the subfamily Aphidiinae (Hymenoptera), as well as eight other generalist natural enemies. In these interactions, a total of 37 aphid-natural enemy associations–including 19 associations of Acyrthosiphon pisum (Harris) with natural enemies, 16 associations of Therioaphis trifolii (Monell) with natural enemies and two associations of Aphis craccivora Koch with natural enemies–were detected on Medicago sativa L. during the sampling period. Similarly, 12 associations of Myzus cerasi (Fabricius) with natural enemies were revealed on Prunus avium (L.), along with five associations of Brevicoryne brassicae (Linnaeus) with natural enemies (including mostly parasitoid individuals) on Brassica oleracea L. Also in the study, reduviids of the species Zelus renardii (Kolenati) are reported for the first time as new potential aphid biocontrol agents in Turkey. The results of field surveys show that the natural enemies of aphids have high biodiversity, which should be considered in the management of biological pest control.

This study aimed to determine aphid species, and to contribute new species and hosts, in Çanakkale and Balıkesir Provinces in the South Marmara Region of Turkey. Samples were taken from different host plants between March 2017 and November 2018. In total 74 aphid species were identified, including three subspecies from 34 genera belong to five subfamilies (Aphidinae, Calaphidinae, Chaitophorinae, Eriosomatinae and Lachninae) of the family Aphididae. Among these, Dysaphis radicola meridialis Shaposhnikov, 1964 collected from the roots of Rumex sp. (Polygonaceae)is a new subspecies record for the aphid fauna of Turkey from Çanakkale. The new host records for Turkey are Ajuga orientalis L. (Lamiaceae) on Aulacorthum (Aulacorthum) solani (Kaltenbach, 1843), Cynoglossum creticum Mill. (Boraginaceae) on Acyrthosiphon (Acyrthosiphon) malvae (Mosley, 1841) and Tragopogon porrifolius L. (Asteraceae) on Trama (Neotrama) caudata Del Guercio, 1909.Also, body measurements, diagnostic features, illustrations, distribution and biology are given for the new aphid records. With this contribution, the number of aphids in the fauna of Turkey has reached to 541 species and 14 subspecies.

En tr In this study, the insecticide effect of Lepidium sativum L., Eruca vesicaria Mill., Mentha pulegium L., Ocimum basilicum L. and Rosmarinus officinalis L. extracts on nymph and adult stage of Two Spotted Spidermite, Tetranychus urticae Koch were determined using leaf disk dipping methods. In the tests, 1, 3, 6 and 12% concentrations of the extracts were used and counting was carried out 24th, 48th, 72nd and 96th hours after the treatments. The tests were prepared such that each concentration had 5 repeats and each repeat included 10 individuals. The highest mortalities of nymph and adult stage of T. urticae were counted as 68% and 96%, respectively, at 12% concentration of R. officinalis. . In the tests using leaf disk dipping method on adult females of T. urticae, the effects of the extracts were arranged as R. officinalis>M. pulegium = O. basilicum>E. vesicaria>L. sativum. As a result, , plant extracts used in this study are thought to be used as an alternative method to pesticides for control of two-spotted spider mites. Bu çalışmada, Lepidium sativum L., Eruca vesicaria Mill., Mentha pulegium L., Ocimum basilicum L. ve Rosmarinus officinalis L. ekstraktlarının İki Noktalı Kırmızıörümcek, Tetranychus urticae Koch’nin nimf ve ergin dönemleri üzerine insektisit etkisi yaprak disk daldırma yöntemi kullanılarak belirlenmiştir. Denemelerde ekstraktların %1, 3, 6, 12 konsantrasyonları kullanılmış ve s ayımlar uygulamadan 2, 6, 24, 48, 72 ve 96 saat sonra, yapılmıştır. Denemeler her konsantrasyon için 5 tekerrür ve her tekerrürde 10 birey olacak şekilde gerçekleştirilmiştir. T. urticae’nin hem nimf hem de ergin dönemlerinde en yüksek ölüm oranları R. officinalis ekstraktının %12’lik konsantrasyonunda sırasıyla %68 ve %96 olarak belirlenmiştir. Bitki ekstraktlarının farklı konstarasyonlarının yaprak disk daldırma yönteminin kullanıldığı denemelerde ergin bireler üzerinde etkisi R. officinalis>M. pulegium = O. basilicum>E. vesicaria>L. sativum olarak sıralanmıştır. Sonuç olarak, iki noktalı kırmızıörümcek ile mücadelede bu çalışmada kullanılan bitki ekstraktlarının pestisitlere karşı alternatif bir yöntem olarak kullanılabileceği düşünülmektedir.
