“…EOs are complex mixture of alcohols, aldehydes, phenol, terpenoids and fatty acid derivatives (Boire et al 2013). A complete GC-MS analysis of the essential oils used in the present paper is available as Supplementary Material 6 in Klein et al (2020). Klein et al sourced their essential oils from the same company that supplied our oils for the present paper.…”

The reason behind selection of above-mentioned oils is that most of the oils have been tested for molluscicidal, insecticidal and acaricidal activity in other studies (Mc Donnell et al 2016;Rios et al 2017;Barua et al 2017;Klein et al 2020).

“…Although 1% is towards the high end of concentrations of EOs, the product Snail & Slug Away® contains 1.35% cinnamon oil as the active ingredient. Also, 1% has been used in the published literature to screen for molluscicidal activity (see Mc Donnell et al 2016;Klein et al 2020). The oil solutions and control were added to 5 separate wells in a 96 well plate.…”

“…The harmful effects of synthetic chemicals on the environment, humans and animal health have prompted scientists to look for alternative control methods, which are more sustainable and less toxic to the environment. In this aspect, essential oils (EOs) have been gaining prominence as a new class of ecological product with antimicrobial, insecticidal, molluscicidal and nematicidal activity (Ejechi et al 1999;Isman 2000;Barbosa et al 2010;Klein et al 2020). The exemption of many EOs from pesticide registrations and residue tolerance requirements under federal law in the USA (Sect.…”

“…EOs are plant-derived products, lipophilic in nature and possess the capacity to hinder metabolic, biochemical, physiological and behavioural functions of insects (Brattsten 1983;Tripathi et al 2009;Mossa 2016). Research findings show that different constituents of EOs, such as terpenes, alcohols, aldehydes, ethers, ketones, phenols and oxides (Boire et al 2013), are effective against various pests including insects, mites, fungi, slugs, snails and nematodes (Isman 2000;Mc Donnell et al 2016;Barua et al 2017;Klein et al 2020). In animal phyla, Nematoda is the second most diverse phylum after arthropods living in a wide range of habitats.…”

Toxicity of essential oils to slug parasitic and entomopathogenic nematodes

Essential oils are being increasingly utilised as a biorational element in integrated pest management regimes. Whereas there has been much research on the effects of these oils on mortality and behaviour of pestiferous molluscs, insects and nematodes, there has (to the present authors' knowledge) been no research into their effects on the mortality and behaviour of beneficial nematodes. We address this lacuna by conducting laboratory assays on the behaviour (thrashing assays) and mortality of 13 essential oils plus controls of Tween and water on the malacophagous nematode Phasmarhabditis hermaphrodita and two species of entomopathogenic nematodes, namely: Steinernema feltiae and Heterorhabditis bacteriophora. Mortality results showed an "all or nothing" response with only three oils-pine oil, peppermint and lemongrass-displaying intermediate mortalities. Also, toxicity of essential oils was conserved across phylogenetically quite distinct beneficial nematode species with oil toxicity largely being repeated across the three beneficial nematodes. Thrashing assays confirmed the toxic effects of certain oils. We recommend that the effects of essential oils be tested on beneficial organisms in ecosystems before choices are made over which oils should be used. The present paper highlights some oils which are not toxic to beneficial nematodes but may affect their behaviour. Research should focus on these oils as part of a biorational control programme for pestiferous molluscs and insects.

Several slug species are highly pestiferous and threaten global sustainable agriculture. Current control methods rely heavily on metaldehyde pellets, which are often ineffective, harm nontarget organisms and have been banned in some countries. A viable alternative is the parasitic nematode Phasmarhabditis hermaphrodita (and recently P. californica), which has been formulated into a biological control agent (Nemaslug®) to control slugs across northern Europe. Nematodes are mixed with water and applied to soil where they seek out slugs, penetrate behind the mantle and kill them in 4–21 days. Phasmarhabditis hermaphrodita has been on the market since 1994 and since then there has been ample research on its use. Here we review the research carried out on P. hermaphrodita over the last 30 years since its development and release as a commercial product. We provide information on life cycle, worldwide distribution, history of commercialisation, gastropod immunity, host range, ecological and environmental factors that affect its success in the field, bacterial relationships, and summarise results of field trials. Finally, we suggest future directions for P. hermaphrodita research (and other Phasmarhabditis species) to enhance its use as a biological control agent to control slugs for the next 30 years. © 2023 The Authors.
