“…As was mentioned in the previous subchapter, the only commercial product based on MPNs (P. hermaphrodita) is Nemaslug © (BASF). Experiments with other nematodes species as bioagents, for example, A. appendiculatum [42,79] and some other rhabditids [80] were already done, but the results and the potential of these nematodes for the use in bio-control are still questionable and too far from practical impact.…”

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.

“…Our knowledge of mollusc/nematode associations is based on surveys in Germany (Mengert 1953), France (Morand 1988), Maine, USA (Gleich et al 1977) and Australia (Charwat and Davies 1999). A comparatively well studied group of parasites associated with terrestrial molluscs is the nematodes, but such associations are understudied compared with nematodes that parasitize vertebrates and insects.…”

The role of parasite release in invasion of the USA by European slugs

et al. 2009

Several species of European slugs are invasive in the USA, threatening native species and damaging agricultural and horticultural crops. One possible explanation for the success of these invaders is parasite release. To test this hypothesis we collected European slugs in part of their native range (United Kingdom) and in the USA and compared prevalence, distribution and species richness of their nematode parasites. All slugs were dissected and examined for the presence of nematodes. In the UK, nematodes were present at 93% of study sites and 16.4% of all slugs examined were associated with nematodes whereas in the USA the respective figures were 34% of sites and 5.4% of slugs. Nematode species richness was greater in the UK with 12 species being found, seven of which were thought to be truly parasitic as opposed to being phoretic or necromenic. Nine species of nematode were found in the USA, four of which were truly parasitic. Four of the ten European slug species examined in the USA, were entirely free of truly parasitic nematodes whereas all were infected by nematodes in some sites in the UK. There was a significant difference in the prevalence of truly parasitic nematodes in five of these species when comparing their home versus invasive range. A significant difference in parasite prevalence was observed when comparing native and introduced slug species in the USA, however, this was not significant in the UK. Our data support a role for parasite release during the invasion of the USA by European slugs.Electronic supplementary material The online version of this article (

“…One of the reasons is that few scientific data are available regarding the snailparasitic nematodes around the world. Our understanding for the snail/nematode associations is mostly based on surveys conducted by Mengert [6] in Germany, Morand [7] in France, Gleich et al [8] in USA and Charwat and Davies [9] in Australia. Currently the confirmed snail -parasitic nematodes is quite limited (e.g.…”

“…For examples, four introduced species of Mediterranean snails [Cernuella virgata (Da Costa), Theba pisana (Müller), Cochicella acuta (Müller) and Cochicella barbara (Linnaeus)], cause serious damage to the grain industry in Australia each year [12]. To control these pest snails efficiently and environment friendly, nematode -based biological control method was regarded as a priority among other options [9].…”

Pest snails are economically important pests of the grain industry. Nematode based bioagent appears to be a hope for controlling pest snails in an environment friendly way. Based on the dataset of 18S rRNA gene sequences, we propose a molecular phylogeny of nematodes baited with Cernuella virgata in soils collected from southern states of Australia. A total of 12 species (representing eight genera of nematodes) were identified and the inferred phylogenetic trees (Neighbor-Joining and Minium Evolution) placed them within three (I, IV and VII) out of the seven clades, indicating the possibility of multiple origins of snail parasitism. In Clade I and Clade VII, nematodes associated with Cernuella virgata formed sister group relationships with some slug-parasitic nematodes. We assume that snail-parasitic nematodes and slug-parasitic nematodes might share common ancestors in their evolutionary histories.
