Effects of Paenibacillus nematophilus on the entomopathogenic nematode Heterorhabditis megidis.
The insect parasitic nematodes Heterorhabditis spp. are mutualistically associated with entomopathogenic bacteria, Photorhabdus spp. A novel association has been detected between H. megidis isolate EU17 and the endospore-forming bacterium Paenibacillus nematophilus. P. nematophilus sporangia adhere to infective juveniles (IJs) of H. megidis and develop in insect hosts along with the nematodes a...
متن کاملPhased activity in Heterorhabditis megidis infective juveniles.
The infectivity of Heterorhabditis megidis infective juveniles (IJs) increases during storage in water. We investigated whether this change can be related to other features of the IJs' behaviour. IJs were stored in water for 4 weeks at 20 degrees C, and the following parameters were assessed at intervals: infectivity for Galleria mellonella, dispersal in sand, host-finding on agar, and the perc...
متن کاملComparative analysis of the expressed genome of the infective juvenile entomopathogenic nematode, Heterorhabditis bacteriophora.
We report the first cDNA-sequencing project of the entomopathogenic nematode, Heterorhabditis bacteriophora. A total of 1246 expressed sequence tags (ESTs) were generated by random sequencing of clones from a cDNA library of the infective juvenile stage. The ESTs were annotated resulting in 1072 useful ESTs that were categorized into functional categories according to Kyoto Encyclopedia of Gene...
متن کاملEcological characterisation of the Colombian entomopathogenic nematode Heterorhabditis sp. SL0708.
The entomopathogenic nematode Heterorhabditis sp. SL0708 (Rhabditida: Heterorhabditidae) isolated from soil in Alcalá, Valle del Cauca (Colombia) was characterised ecologically using Galleria mellonella larvae (L) (Pyralidae: Galleriinae) as hosts. The effect of temperature on the viability, infectivity and reproduction, and of moisture on infectivity and storage in liquid were evaluated in inf...
متن کاملEntomopathogenic Nematode Genome Consortium: Sequencing and Annotation of Heterorhabditis bacteriophora Project Summary: This project aims to sequence the genome of the entomopathogenic nematode Heterorhabditis bacteriophora strain TTO1
Heterorhabditis bacteriophora Project Summary: This project aims to sequence the genome of the entomopathogenic nematode Heterorhabditis bacteriophora strain TTO1 as a representative of 45 other species that are used as biological control agents for insect pests worldwide. This nematode is closely related to the two already sequenced free-living nematodes, Caenorhabditis elegans and C. briggsae...
