Soil-borne nematodes establish close associations with several bacterial species. Whether they confer benefits to their hosts has been investigated in only a few nematode-bacteria systems. Their ecological function, therefore, remains poorly understood. In this study, we isolated species from rhabditid nematodes, molecularly identified them, evaluated entomopathogenic potential on Galleria mellonella larvae, and measured immune responses of G . larvae infection. Bacteria were Acrobeloides...
A survey to collect soil nematodes with potential control Ceratitis capitata flies was carried out in different locations Tunisia. Several nematode isolates were recovered, laboratory colonies established, and their taxonomic identities determined based on molecular methods. Among all the recovered isolates, two of them, Oscheius tipulae TC2 OC2, evaluated for capacity C . ability kill reproduce Galleria mellonella larvae. Our results show a great these as biocontrol agents they eggs pupae...
Four bacterial strains, A-IN1T, A-TC2T, E-TC7T, and K-TC2T, isolated from soil-borne nematodes of the species Oscheius tipulae Acrobeloides bodenheimeri, were found to represent new genera Acinetobacter, Alcaligenes, Enterobacter, Kaistia, respectively. In this study, we described these using a polyphasic taxonomic approach that included whole-genome whole-proteome phylogenomic reconstructions, core genome sequence comparisons, phenotypic characterization. Phylogenomic reconstructions...
Abstract Grapevine fanleaf virus (GFLV) is one of the most severe diseases grapevines, causing degeneration that transmitted by Xiphinema index. This paper aims to isolate species from Tunisian vineyard soil samples and assess their ability acquire transmit GFLV under natural controlled conditions. Based on morphological morphometric analyses, dagger nematodes were identified as X. index italiae. These results confirmed with molecular identification tools using species-specific polymerase...
Summary Four populations of Acrobeloides nematodes were isolated from Tunisian soils. Based on morphological and morphometric data, two populations, TC9 HWO, identified as A. tricornis the other two, TC7 K18g, bodenheimeri. is distinguished its closely related species by high labial probolae with arcuate termini, inconspicuous post-uterine sac, five lateral incisures, while bodenheimeri acrobeloids having a low rounded probolae, distinct vulva frequently vaginal plug. The reported in this...
Tylenchulus semipenetrans Cobb, is a parasitic nematode of citrus, causing significant reduction in citrus growth and yield. Biological antagonists including bacteria fungi have been used to control nematodes. Citrus rhizosphere were collected from mature orchards Tunisia they studied evaluate their nematicidal potentials on abilities stimulate plant root growth. Sixty bacterial strains isolated egg masses nematode, roots associated trapping fungi, tested for parasitize T. impact parameters....
Abstract Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) red palm weevils are often reported in association with different organisms including nematodes. The significance of this interaction and whether nematodes can influence their life‐history traits is unclear. We collected at developmental stages locations Tunisia, observed dissected them search for other interacting organisms, established laboratory colonies identified the associated them, conducted nematode–insect assays...
La reponse de deux porte-greffes Citrus les plus utilises en agrumiculture a ete etudiee sur le plan histologique.

Poncirus trifoliata presente une resistance par necrose cellulaire. greffage du confere aux racines cellulaire au biotype mediterraneen citrus. P. vis-a-vis T. semipenetrans est liee action allelochimique.
This review of the literature on Fanleaf disease, illustrated by fieldwork in Tunisia, is important view destructive nature disease and interaction between virus strains different species nematodes that are its vector. Two nepoviruses associated with disease: Grapevine Fan Leaf Virus (GFLV) Arabis mosaic (ArMV). Xiphinema index italiae, which reproduce parthenogenetically, vectors GFLV, whereas diversicaudatum, predominantly sexual reproduction, vector ArMV. The determinants transmission...
Monacrosporium salinum strain, MSO03, isolated from Omani horticultural agro-ecosystem in 2003, has been compared to patented strains, MST84, 1984 Tunisian soils. Morpho-biometrical characteristics demonstrated that MSO03 was similar MST84. However, conidia of were longer as those Furthermore, strain produce specifically single chlamydospores rounded, showing thick cell wall, while known M. are flattened, chains with thin wall. Consequently, the can resist more severe stress conditions, such...
The direct and indirect modulating effects of two citrus soil bacteria, Bacillus thuringiensis subtilis, on the activity nematophagous fungi, Arthrobotrys conoides Dactylellina gephyropaga, have been studied. Growth rates A. D. effect gephyropaga mycelial growth conidial germination conoides, antifungal B. subtilis against other phytopathogenic fungal species were assessed. Characterisation bioactive molecules synthesised by PCR amplification Nonribosomal peptide synthetases (NRPS) genes...
Depuis la découverte du charançon rouge palmier Rhynchophorus ferrugineus en Tunisie décembre 2011, ce ravageur est devenu invasif et mortel pour les palmiers. L’apparition tardive des symptômes représente l’obstacle majeur qui entrave l’efficacité de lutte. Afin mieux contrôler ravageur, un élevage masse a été réalisé étudier ses traits d’histoire vie (THV). Allant l’œuf à l’adulte sur milieu artificiel dans conditions laboratoire, durée d’incubation œufs 5 jours, celle développement...
To better understand the distribution and genetic variety of Grapevine fanleaf virus (GFLV) in two organs grapevine, presence this was tested leaf pollen samples by ELISA RT-PCR methods. On average, GFLV is present leaves with percentages 93 36% respectively. Capsid protein sequences were aligned showed 85–92,1% identity at nucleotide level for isolates obtained from 96–99% pollen. are less divergent phylogenetically closer to each other than those detected based on analysis 2 CP sequences....
