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 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...
متن کاملThe influence of habitat quality on the foraging strategies of the entomopathogenic nematodes Steinernema carpocapsae and Heterorhabditis megidis.
Entomopathogenic nematodes (EPN) are soil-transmitted parasites and their foraging strategies are believed to range from 'ambush' to 'cruise' foragers. However, research on their behaviour has not considered the natural habitat of these nematodes. We hypothesized that EPN behaviour would be influenced by soil habitat quality and tested this hypothesis using 2 EPN species Steinernema carpocapsae...
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...
