This study was conducted in 2020 to investigate the influence of melatonin (10, 50 and 100 µM) given in three methods (immersion, irrigation, and foliar spraying) on some physiological aspects of tomato seedlings inoculated with root-knot nematode Meloidogyne incognita [(Kofoid and White) Chitwood]. The seedlings were inoculated with 1000 second-st...
Lemon palm (Melissa officinalis L.), a perennial plant from Lamiaceae family, is cultivated in all Mediterranean countries and coastal regions of Turkey. It can be attacked by several pathogens like nematodes which reduce its yield and quality. In this study, morphometric measurements, morphological and molecular identifications were done using juv...
This research was conducted in 2020 to investigate the influence of melatonin (10, 50 and 100 µM) given in three methods (immersion, irrigation and foliar spraying), on some physiological aspects of tomato seedlings exposed to root knot nematodes. The seedlings were inoculated with 1000 infective juveniles of Meloidogyne incognita [(Kofoid and Whit...
The Mediterranean fruit fly, Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae), is one of the world’s
most destructive fruit pests. Ceratitis capitata pupates in the soil, making it a target of many soilborne pathogens like
entomopathogenic nematodes (EPNs). Entomopathogenic nematodes are highly lethal to many important pests, safe
to non...
The diversity and distribution of soil nematodes were studied in Mount Ararat from the altitude of 1523 to 5000 m a.s.l., in habitats with different ecological characteristics. A total of 2,561 individuals were identified belonging to 31 families, 62 genera and 70 species. The nematode diversity (species richness) and the nematode abundance display...
Calendula officinalis L. (Asteraceae) is a traditional medicinal plant called pot marigold or English marigold. In this study, galled roots of pot marigold were collected from Balıkesir province of Turkey and egg masses were picked up from the roots of each plant with fine forceps. DNA was then extracted from samples and analyzed by species-specifi...
In this study conducted in 2020, three concentrations (1, 5 and 10 µM) of 24-epibrassinolide were applied to seedlings of Lycopersicon esculentum Mill. (Solanales: Solanaceae) cv. H2274, which is susceptible to root-knot nematodes, by immersion, spray and irrigation, and its effects against root-knot nematode Meloidogyne incognita (Kofoid & White,...
In this study, the efficacy of Turkish isolates of four entomopathogenic nematodes (EPNs) against the last instar larvae of the potato tuber moth, Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae) were investigated under laboratory conditions. Potato moths were collected from infested potato fields in Derinkuyu (Nevşehir Province) in June 2...
Wheat is one of the most important cultivated plants in our country. The main pest that causes economic losses in wheat production is sunn pest Eurygaster integriceps. In this study the mortality of three native entomopathogenic nematodes (EPNs) species Steinernema feltiae (Yalova), S. carpocapsae (Sakarya) and Heterorhabditis bacteriophora (Sakar...
In this study the virulence of Steinernema affine 46, S. feltiae 96, S. carpocapsae 1133 and Heterorhabditis bacteriophora 1144 isolates against the last instar larvae of Palpita unionalis (Hübner) were investigated on plates in laboratory and pots in a climate room. Efficacy of entomopathogenic nematodes were determined at 25 oC using two differen...
This paper presents a study of free-living nematodes (excepting Dorylaimida) from Mount Ararat, Turkey. A total of 25 species are recorded, which belong to the orders Enoplida (one species), Triplonchida (2), Chromadorida (1), Monhysterida (2), Plectida (4) and Rhabditida (18). Nine of them are new for the Turkish fauna: Acrobeles andalusicus, A. c...
The pine processionary moth, Thaumetopoea pityocampa Den. & Schiff. (Lepidoptera: Thaumetopoeidae), is one of the most important pests of forest trees. In this study, the efficacy of native entomopathogenic nematodes (EPNs) against the larvae of T. pityocampa was investigated under laboratory conditions. Isolates of Steinernema carpocapsae Weiser,...
Amerikan beyaz kelebeği, Hyphantria cunea (Drury) (Lepidoptera: Arctiidae) birçok süs bitkisi ve çalının yanı sıra fındık gibi önemli bazı tarımsal ürünlerin de zararlısıdır. Bu çalışmada yerel entomopatojen nematodların (EPN) H. cunea’nın larvaları üzerinde meydana getirdikleri ölüm oranları laboratuvar koşullarında araştırılmıştır. Çalışmada dört...
In this study, plant parasitic nematode fauna from Mount Ararat is described with respect to altitude. A total of 30 soil samples were taken in 2013 during the summer season. Nematodes were extracted by using modified Baermann’s (1917) funnel technique. The identification of nematodes were done with morphologic characters, morphometric measurements...
Bu çalışmada yerel entomopatojen nematod izolatları olan Steinernema affine (46), Steinernema feltiae (96) türlerinin Zeytin fidan tırtılı Palpita unionalis (Hübner) son dönem larvaları üzerindeki etkinlikleri laboratuvar ve saksı koşullarında araştırılmıştır. P. unionalis larvaları Çanakkale İli'ndeki zeytin bahçelerinden toplanmıştır. Laboratuvar...
