“…The efficacy of P. hermaphrodita is not affected by preceding cover crop (ryegrass, vetch and red clover), and this does not influence survival of nematodes in soil or their ability to cause disease in slugs 76. Field trials in Chile showed that P. hermaphrodita applied in lupin continued to provide protection against slugs in the following corn crop 77…”

Phasmarhabditis hermaphrodita Schneider (Nematoda: Rhabditidae) is a nematode that parasitises a wide range of slug and snail species. It has been formulated into a biological control agent (Nemaslug) and was commercialised in 1994. It is now available in fourteen European countries. A review is given of all research on P. hermaphrodita, including basic biology, mass cultivation, formulation, host range, application strategies, field efficacy and effects on non-target organisms. The many critical gaps in present knowledge are highlighted, and future research is proposed that will lead to greater understanding of this unusual parasite and may enable its more widespread use in the management of mollusc pests.

“…Chile is no exception in the international push for alternatives to chemical pesticides and, through the Instituto de Investigaciones Agropecuarias (INIA), is investigating biological control alternatives using microorganisms and nematodes (France et al, 2002;Rodríguez et al, 2006). Surveys for entomopathogenic fungi from Chile have revealed a diverse array of isolates (Becerra Velásquez et al, 2007), although the country remains largely unexplored for EPN and there are no published records of topography, the average lateral distance from the peaks of the Andes to the coast being only 175 km.…”

A new species of entomopathogenic nematode, Steinernema australe n. sp., was isolated from a soil sample taken close to the beach on Isla Magdalena, an island in the Pacific Ocean, 2 km from mainland Chile. Morphologically the new species belongs to the glaseri-group and is characterised by morphometrics of the infective juvenile which has a very long body of 1316 (1162-1484) μm, excretory pore located far posterior to the anterior extremity (110 (95-125) μm), exceptionally long tail of 103 (92-114) μm, H% = 51 (42-61), E% = 107 (94-122) and a ratio = 35 (31-38). The first generation male has 72 (55-78) μm long spicules, a 45 (36-51) μm long gubernaculum and . The first generation female can be recognised by well developed double epiptygmata, the lack of a prominent postanal swelling, a mucron on the tail tip and (in 60% of individuals) one to two subsidiary mucrons. Sequences of the ITS and D2D3 regions of the ribosomal DNA confirm that S. australe n. sp. is a valid species.

“…When manure was applied before P. hermaphrodita dauer juveniles, the nematodes were rendered ineffective, possibly as a result of poor dauer survival, manure interfering with chemoreception or the manure attracting more slugs 181 . By contrast, there was no effect of cover crops or lupin on the ability of nematodes to control slugs in the next crop planted 199,200 …”

“…181 By contrast, there was no effect of cover crops or lupin on the ability of nematodes to control slugs in the next crop planted. 199,200 Novel application strategies that improve efficiency and economic use of nematode biological control products will improve their attractiveness, 201 which have been investigated with P. hermaphrodita. For example, the most efficient control method of slugs in sugar beet utilised nematode application and methiocarb pellets in furrow treatment; 202 however, it has been found that methiocarb can reduce nematode survival but not infectivity.…”

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.
