Heterorhabditis safricana n. sp. (Rhabditida: Heterorhabditidae), a new entomopathogenic nematode from South Africa
During a survey for entomopathogenic nematodes in the Western Cape Province of South Africa, a new species in the genus Heterorhabditis was collected from a peach orchard. The nematode was trapped by the insect-baiting technique using last instar larvae of Galleria mellonella. The infective juvenile of the new species differs from the morphologically closest species, H. marelatus, in shorter bo...
متن کاملHeterorhabditis noenieputensis n. sp. (Rhabditida: Heterorhabditidae), a new entomopathogenic nematode from South Africa.
A new entomopathogenic nematode in the genus Heterorhabditis is described from South Africa, from two singular isolates found 1000 km from each other, from beneath a fig tree and in a citrus orchard, respectively. Morphological and molecular studies indicate both isolates to be the same and a new undescribed Heterorhabditis species. Comparison of sequences of the internal transcribed spacer (IT...

یک گونه نماتد بیمارگر حشرات، با استفاده از روش تله‌گذاری خاک با لارو پروانه‌ی موم‌خوار(Galleria mellonella (L.)) از نمونه خاک‌های جمع‌آوری‌شده از حومه‌ی مرند، استان آذربایجان شرقی، شمال غرب ایران جداسازی گردید. این گونه بر اساس صفات ریخت‌شناسی، داده‌های ریخت‌سنجی و نیز بررسی‌های مولکولی به عنوان Steinernema bicornutum Tallosi, Peters & Ehlers, 1995 شناسایی شد. در مقایسه‌های ریخت‌شناسی، تفاوت آش...
متن کاملGenetic Variability among Strains of the Entomopathogenic Nematode Steinernema feltiae.
A systematic program of genetic improvement was initiated by assessing the phenotypic variation of Steinernema feltiae strains for two traits assumed to limit efficacy: ultraviolet tolerance and host-finding ability. All of the strains assayed showed both low ultraviolet tolerance and poor host-finding ability, indicating that the likelihood of improving these traits through more extensive popu...
متن کاملSoil sampling and isolation of entomopathogenic nematodes (Steinernematidae, Heterorhabditidae).
Entomopathogenic nematodes (a.k.a. EPN) represent a group of soil-inhabiting nematodes that parasitize a wide range of insects. These nematodes belong to two families: Steinernematidae and Heterorhabditidae. Until now, more than 70 species have been described in the Steinernematidae and there are about 20 species in the Heterorhabditidae. The nematodes have a mutualistic partnership with Entero...
