| 16s rdna-based phylogeny of non-symbiotic bacteria of entorno-pathogenic nematodes from infected insect cadavers. | using 16s rdna gene sequencing technique, three different species of non-symbiotic bacteria of entomopatho-genic nematodes (epns) (steinernema sp. and heterorhabditis sp.) were isolated and identified from infected insect cadavers {galleria mellonella larvae) after 48-hour post infections. sequence similarity analysis revealed that the strains srk3, srk4 and srk5 belong to ochrobactrum cytisi, schineria larvae and ochrobactrum anthropi, respectively. the isolates o. anthropi and s. larvae were f ... | 2011 | 21802047 |
| directional movement of entomopathogenic nematodes in response to electrical field: effects of species, magnitude of voltage, and infective juvenile age. | entomopathogenic nematodes respond to a variety of stimuli when foraging. previously, we reported a directional response to electrical fields for two entomopathogenic nematode species; specifically, when electrical fields were generated on agar plates steinernema glaseri (a nematode that utilizes a cruiser-type foraging strategy) moved to a higher electric potential, whereas steinernema carpocapsae, an ambush-type forager, moved to a lower potential. thus, we hypothesized that entomopathogenic n ... | 2012 | 21945052 |
| temperature effect on novel entomopathogenic nematode steinernema siamkayai stock, somsook and reid (n. sp.) and its efficacy against spodoptera litura fabricius (lepidoptera: noctuidae). | the efficacy of steinernema siamkayai is a new species that isolate in thailand and the well known previous species are steinernema carpocapsae and steinernema riobrave against 3rd instar larvae of common cutworm, spodoptera litura, and last instar larvae of greater wax moth, galleria mellonella was evaluated under laboratory condition. the optimal temperature for new entomopathogenic nematode, s. siamkayai at 50 and 100 ijs per larvae to penetrate into s. litura and g. mellonella larvae were hi ... | 2009 | 20222622 |
