“…Soil dwelling invertebrates movement is usually slow, but still too fast for the nematodes and thus, during their evolution, parasitic nematodes developed useful adaptations. As known from EPNs, also P. hermaphrodita [39,40] but very probably also many other nematodes, readily react to host-associated cues. This can be CO 2 or other volatile compounds produced by the living host, its faeces, mucus, etc.…”

“…Therefore, the nematodes that readily react to these cues gain an advantage and increase their chance to meet the suitable host. Interesting finding is that P. hermaphrodita can strongly react not only to water soluble cues as most of other nematodes do but also to volatile cues [40], which can be related with its habitat, soil surface and organic matter, which is inhabited by its hosts.…”

Entomopathogenic and molluscoparasitic nematodes are important parasites of many insects and molluscs, respectively. Due to their infectivity, the possibility of mass production by industrial techniques and the relative safety to nontarget organisms and environment, these organisms represent an attractive agent for biological control of many pests. This chapter summarises the current knowledge of the diversity of these organisms. In this chapter, we review the recent advances in production, storage, application techniques genetic improvement and safety of these organisms.

“…Apart from the parasitic cycle, P. hermaphrodita also has a necromenic life cycle (Mengert, 1953) and has been shown to reproduce on earthworms (Rae, Robertson, & Wilson, 2009), leaf litter (MacMillan et al, 2009 and slugs or slug faeces homogenates (Tan & Grewal, 2001) that are very strong attractants for this nematode (Nermuť, Půža, & Mráček, 2012;Rae, Robertson, & Wilson, 2006). However, only a few studies have assessed the influence of different growth substrates, on the development and reproduction of P. hermaphrodita.…”

The effect of different growing substrates on the development of the slug parasite Phasmarhabditis hermaphrodita has been studied in a series of laboratory experiments. Wild, laboratory and Nemaslug strains of P. hermaphrodita and their monoxenic counterparts with Moraxella osloensis (CCM 5605T) were reared on homogenised pig kidney, Deroceras reticulatum, Arion lusitanicus, and Galleria mellonella, the faeces of D. reticulatum and A. lusitanicus, or leaf compost. Development time, yield, lipid reserves and the body length of nematodes were assessed. All P. hermaphrodita strains were able to grow and reproduce on all tested substrates; however, yields were markedly higher on invertebrate media. Lipid content and body size varied across the substrates and strains. A uniform response of all nematode strains and the most dramatic differences among substrates were recorded in yields, which could indicate that the quality of the substrate is expressed mainly in yield. Monoxenized strains had higher yield, length, lipid content and shorter development time. In general, the strain differences between the observed parameters were most likely due to different bacterial associates. The dramatic differences in yields on invertebrate substrates, in comparison to the others, illustrate the evolutionary advantage of the association of nematodes with invertebrates.

“…Alternatively, C. briggsae could be attracted to hosts and C. elegans just follows that species. P. hermaphrodita shares habitats and mollusk hosts with C. elegans and C. briggsae (Rae et al, 2009;Petersen et al, 2015;Schulenburg & Félix, 2017) and has been shown to chemotax toward the mucus, faeces, and volatile odorants of slugs and, in the case of snails, hyaluronic acid (Rae et al, 2006(Rae et al, , 2009Hapca et al, 2007;Small & Bradford, 2008;Nermut et al, 2012;Andrus et al, 2018). This observation suggests that C. elegans might prefer mollusks to isopods such as P. scaber and testing attraction to these species is a good future step.…”

Phoresy is a behavior in which an organism, the phoront, travels from one location to another by 'hitching a ride' on the body of a host as it disperses. Some phoronts are generalists, taking advantage of any available host. Others are specialists and travel only when specific hosts are located using chemical cues to identify and move (chemotax) toward the preferred host. Free-living nematodes, like Caenorhabditis elegans, are often found in natural environments that contain terrestrial isopods and other invertebrates. Additionally, the C. elegans wild strain PB306 was isolated associated with the isopod Porcellio scaber. However, it is currently unclear if C. elegans is a phoront of terrestrial isopods, and if so, whether it is a specialist, generalist, or developmental stage-specific combination of both strategies. Because the relevant chemical stimuli might be secreted compounds or volatile odorants, we used different types of chemotaxis assays across diverse extractions of compounds or odorants to test whether C. elegans is attracted to P. scaber. We show that two different strains -the wild isolate PB306 and the laboratory-adapted strain N2 -are not attracted to P. scaber during either the dauer or adult life stages. Our results indicate that C. elegans was not attracted to chemical compounds or volatile odorants from P. scaber, providing valuable empirical evidence to suggest that any associations between these two species are likely opportunistic rather than specific phoresy.
