The insecticidal effect of Heterorhabditis bacteriophora Poinar (Nematoda: Heterorhabditidae), Steinernema carpocapsae (Weiser) (Nematoda: Steinernematidae), and Steinernema feltiae (Filipjev) (Nematoda: Steinernematidae) against Mediterranean flour moth, Ephestia kuehniella (Zeller) (Lepidoptera: P...

Journal of Parasitology (96)3 2010
Abstract
We extracted all the nematode fauna present on 114 individuals of G. stercorosus. By direct sequencing using the 18S SSU, we provide a barcode for all nematodes isolated from the beetle samples. In total, 5,002 dauer-stage nematodes were sequenced, which included Pristionchus spp., Koerneria spp. (D...

Abstract
Modern morphology-based systematics, including questions of incongruence with molecular data, emphasizes analysis over similarity criteria to assess homology. Yet detailed examination of a few key characters, using new tools and processes such as computerized, three-dimensional ultrastructural recon...

Abstract
We report a fourth fatal case, which occurred in a 39-year-old woman who presented with meningeal signs, altered mental status, and a prodromal pruritic rash. Diagnostic evaluation included an open brain biopsy, which was diagnosed as granulomatous vasculitis. The patient subsequently died after a c...

Abstract
We determined that four major terpene compounds were produced by infested plant roots that were not found in samples from non-infested roots or soil that contained only larvae. Solvent extracts of weevil-infested roots attracted more nematodes than extracts of non-infested roots in a two choice sand...

Abstract
We construct a simple individual-based model of host-parasite dynamics during range expansion. This model shows that the parasites and pathogens of a range-expanding host are likely to be absent from the host's invasion front, because stochastic events (serial founder events) in low-density frontal...

Parasitology (137)2 2010
Abstract
We hypothesized that EPN behaviour would be influenced by soil habitat quality and tested this hypothesis using 2 EPN species Steinernema carpocapsae (an 'ambusher') and Heterorhabditis megidis (a 'cruiser') in 2 contrasting habitats, sand and peat. As predicted from previous studies, in sand most S...

Abstract
The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is considered one of the main pests that affect fruit production in the world. This insect spends part of its life cycle in the soil, making it a target for entomopathogenic nematodes. This work aimed at evaluating the influence of soil te...

Abstract
We tested the efficacy of five pathogens over the course of three seasons in 10 Michigan apple and cherry orchards, with introductions of larvae to caged pots containing pathogen-treated soil.

Abstract
We demonstrate that the presence of either of the two nematodes tested deters the beetles from consuming infected cadavers. As P. hermaprodita cannot infect an insect host, we hypothesise the deterrent effect being an evolutionary adaptation of the nematode/bacteria complex rather than the ability o...

Abstract
The free-living infective juveniles of the entomopathogenic nematodes are non-feeding, so the stored energy reserves in these juveniles are of great importance. The relationship between the energy reserves and the efficacy of the entomopathogenic nematodes of genera Heterorhabditis and Steinernema w...

Abstract
We showed that of all the Xenorhabdus species examined, only X. nematophila has the nilA, nilB, and nilC genes. By exposing S. carpocapsae to other Xenorhabdus spp., we established that only X. nematophila is able to colonize S. carpocapsae; therefore, the S. carpocapsae-X. nematophila interaction i...

Abstract
We give evidence that emergence is triggered by ammonia, a product of nematode defecation. We found that the emergence of Steinernemafeltiae infective juveniles from Galleriamellonella cadavers was stimulated by a particular level of ammonia. Emergence was delayed when ammonia in the cadaver was dec...
