“…Recently a new molluscicide containing iron phosphate has been commercialised and shows promise for slug control, particularly in organic agriculture,8 and other pellets have been developed containing chelated iron compounds 9. However, it has been suggested that high doses of iron phosphate increase mortality and reduce surface foraging activity of earthworms 10…”

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.

“…Of the less harmful methods of chemical control, iron phosphate (Ferramol) has been effective against species of slugs and is relatively non toxic (Procop 2005). However, high numbers of iron phosphate pellets may increase earthworm mortality (Langan and Shaw 2006). Biological control using the nematode Phasmarhabditis hermaphrodita Schneider (Nematoda: Rhabditidae), has been successfully used, not only against slugs (Grimm 2002), but also to some extent against snails (Coupland 1995).…”

Populations of two molluscs, the land snail Arianta arbustorum and the Iberian slug Arion lusitanicus, have increased substantially in many places in the northern Fennoscandia in recent years. This has resulted in considerable aesthetic and economic damage to plants in home gardens and commercial nurseries. Birch tar oil (BTO), is a new biological plant protection product, and was tested against these molluscs. In this study we examined whether 2 types of BTO, used either alone, mixed together, or mixed with Vaseline ® , could be applied as 1) a biological plant protection product for the control of land snails by direct topical spray application, 2) as a repellent against snails when painted on a Perspex ® fence, and 3) as a repellent against slugs when smeared on pots containing Brassica pekinensis seedlings. Both the fences and the pots with seedlings were placed in each field with a high population of the target organism. When applied as a spray on snails, BTO did not act as a toxic pesticide but rendered the snails inactive for a period of several months. The BTO barriers were effective in repelling both snails and slugs. However, the repellent effect of BTO alone against the molluscs was short-term. Repeated treatments were required to keep the slugs away from the plants and we found that the interval between treatments should not exceed two weeks. A collar fastened around the rim of the pots, combined with the BTO treatment, did not give any additional benefit in hindering slugs from invading the plants. Most noticeably, the BTO+Vaseline ® mixture prevented the land snails from passing over the treated fences for up to several months. The results of these experiments provide evidence that BTO, especially when mixed with Vaseline ® , serves as an excellent long-term repellent against molluscs.

“…Considerando a los oligoquetos terrestres, se detectó que metaldehído aplicado en forma de pellets a las dosis utilizadas en el campo, e incluso superiores, no afecta la supervivencia, ganancia de peso ni el comportamiento de estos organismos (Bieri et al, 1989;Bieri, 2003;Iglesias et al, 2003;Langan y Shaw, 2006;Edwards et al, 2009;Salvio et al, 2011). Resultados similares se observaron con los cebos en base a metaldehído y/o carbaril (Salvio, 2012).…”

<p>El objetivo del trabajo fue determinar los efectos letales y subletales de metaldehído y/o carbaril sobre Folsomia candida. Se realizaron tres bioensayos bajo un diseño completamente aleatorizado con cuatro repeticiones y en condiciones controladas (20 ± 2 ºC y 14L:10O). La unidad experimental fue un recipiente (9,3 cm de diámetro y 6,4 cm de altura) donde se colocaron 60 g de suelo mezclado con las dosis del cebo y 10 individuos adultos (2 a 3 mm de longitud). Los tratamientos fueron: 0, 40, 80, 120, 160 y 200 g de ingrediente activo (IA) ha-1 de metaldehído; 0, 80, 160, 240, 320 y 400 g IA ha-1 de carbaril; y 0, 40+80, 80+160, 120+240, 160+320 y 200+400 g IA ha-1 de metaldehído+carbaril. Con metaldehído tanto la proporción de individuos vivos como el número de crías no difirieron entre los tratamientos a los 7, 14, 21 y 28 días después de la aplicación (DDA) (p> 0,05). Las dosis mayores de carbaril y metaldehído+carbaril ocasionaron disminuciones en la proporción de individuos vivos y en el número de crías a los 28 DDA (p< 0,05). Los cebos que contienen carbaril causaron mortalidad y disminución en el número de crías de F. candida.</p>
