Entomopathogenic nematode - Heterorhabditis indica and its compatibility with other biopesticides on the Greater wax moth - Galleria mellonella ( L . )
Pathogenic effect of an indigenous entomopathogenic nematode, Heterorhabditis indica and commercial biopesticides of three fungal pathogens (M. anisopliae, B. bassiana and T. viride), one antagonistic bacteria (P. fluorescence), and two neem based biopesticides (Neem and Nimor) were tested on the Greater wax moth, Galleria mellonella larva under laboratory condition. The efficacy of the biopest...
متن کاملDraft Genome Sequence and Assembly of Photorhabdus heterorhabditis Strain VMG, a Bacterial Symbiont Associated with the Entomopathogenic Nematode Heterorhabditis zealandica
Here, we report the draft genome sequence of Photorhabdus heterorhabditis strain VMG, a symbiont of the entomopathogenic nematode Heterorhabditis zealandica in South Africa. The draft genome sequence is 4,878,919 bp long and contains 4,023 protein-coding genes. The genome assembly contains 262 contigs with a G+C content of 42.22%.
متن کاملIsolation and Identification of Photorhabdus Luminescens an Insect Pathogenic Bacteria Associated with Entomopathogenic Nematode
Photorhabdus luminescens is a gram negative symbiotic bacterium belonging to the family Enterobacteriaceae, and is a lethal pathogen of insects. It lives in the gut of an entomopathogenic nematode of the family Heterorhabditidae. When the nematode infects an insect, P. luminescensis released into the blood stream and rapidly kills the insect host by producing toxins. So the present study was ca...
متن کاملResponses of the entomopathogenic nematode, Steinernema riobrave to its insect hosts, Galleria mellonella and Tenebrio molitor.
Potential hosts for infective juveniles of entomopathogenic nematodes can vary considerably in quality based on the characteristics of the host species/stage, physiological status (e.g. stress, feeding on toxins), and infection status (heterospecific or conspecific infection). In this study, we investigated responses of the entomopathogenic nematode Steinernema riobrave to hosts (Galleria mello...
متن کاملPathogenicity of bacterium, Xenorhabdus nematophila isolated from entomopathogenic nematode (Steinernema carpocapsae) and its secretion against Galleria mellonella larvae.
The entomopathogenic bacterium, Xenorhabdus nematophila was isolated from the hemolymph of Galleria mellonella infected with Steinernema carpocapsae. The bacterial cells and its metabolic secretions have been found lethal to the Galleria larvae. Toxic secretion in broth caused 95% mortality within 4 d of application whereas the bacterial cells caused 93% mortality after 6 d. When filter and san...
