“…Communication between the sexes of P. redivivus declined with mating and age [8]. The response time of R. pe/lio males increased with age, but female production of pheromone was similar in the tested ages [14]. Additionally, no daily rhythmicity of pheromone production or response was evident.…”

“…Virgin Panagrolaimus rigidus showed mutual heterosexual attraction, but no homosexual aggregation [15]. Only virgin R. pellio revealed a stronger female responsiveness when compared to the male's reaction [14]. Among other species, Pelodera teres [16], Cylindrocorpus longistoma and C. cruzzi [ 17], and Cephalobus persegnis [ 18], only males are attracted.…”

The literature suggests that chemical communication by primer and releaser pheromones may be extensive within the helminths. Although our detailed knowledge of these events is sparse, the number of reports indicates that a chemical mediation of developmental, reproductive. and behavioral processes may be mandatory in the nematodes, acanthocephala, and other aschelminths. Accordingly, this review presents a summarY' of our current status.

Recently, much attention has been focused on a group of rhabditid nematodes called Phasmarhabditis, a junior synonym of Pellioditis, as a promising source of biocontrol agents for invasive slugs. Pellioditis pelhamensis n. sp. was first isolated from earthworms near Pelham Bay Park in Bronx, New York, USA, in 1990 and has been found to be pathogenic to slugs as well as some earthworms. It has also been used in several comparative developmental studies. Here, we provide a description of this species, as well as a redescription of a similar earthworm-associated nematode, Pellioditis pellio Schneider, 1866, re-isolated from the type locality. Although P. pelhamensis n. sp. and P. pellio are morphologically similar, they are reproductively isolated. Molecular phylogenetic analysis places both species in a clade that includes all species previously described as Phasmarhabditis which are associated with gastropods. Phasmarhabditis Andrássy, 1976 is therefore a junior synonym of Pellioditis Dougherty, 1953. Also, Pellioditis bohemica Nermut’, Půža, Mekete & Mráček, 2017, described to be a facultative parasite of slugs, is found to be a junior synonym of Pellioditis pellio (Schneider, 1866), adding to evidence that P. pellio is associated with both slugs and earthworms. The earthworm-associated species P. pelhamensis n. sp. and P. pellio represent different subclades within Pellioditis, suggesting that Pellioditis species in general have a broader host range than just slugs. Because of this, caution is warranted in using these species as biological control agents until more is understood about their ecology.

“…Even without illustrations, it is sometimes clear that P. pellio or a very closely related species was used. Poinar & Thomas [79] and Somers et al [65] investigated a rhabditid they called "Rhabditis pellio" from the earthworm Aporrectodea trapezoides in California. From their introduction, it is clear that these authors were aware of the differences between Bütschli's leptoderan "R. pellio" and the actual peloderan P. pellio of Schneider [79].…”
