Molluscicidal baits for control of terrestrial gastropods.

Abstract

The active ingredients incorporated into molluscicidal baits (such as metaldehyde and carbamate compounds) for the control of terrestrial gastropods (including Deroceras reticulatum, Arion hortensis and Tandonia budapestensis); antifeedant properties of these chemicals; use of attractants, feeding stimulants, adjuvants and appropriate pellet size and density in the production of molluscicidal baits; factors that affect the field efficacy of these baits (weather, species and age variation in pest susceptibility, availability of alternative hosts, learning and habituation, bait persistence, and molluscicide resistance); field assessment of efficacy; and adverse effects on nontarget organisms are discussed.

The efficacy of three metaldehyde pellets marketed in Argentina, on the control of Deroceras reticulatum (Müller) (Pulmonata: Stylommatophora)

“…It is recognized that prevailing environmental conditions can strongly influence both slug activity and molluscicide efficacy. Slugs are most active in crops at night or following rain on overcast days (Bailey, 2002). Chabert (1996), reported that under moist conditions the effectiveness duration of metaldehyde pellets was about one week, but the duration was longer under dry conditions, approx.…”

“…However, chemical control is the main strategy utilized (Chabert, 1996;Coupland, 1996;Meredith, 1996;Costamagna et al, 1999;Bailey, 2002;Iglesias et al, 2002).…”

“…These are often formulated as bait pellets and act as stomach poisons (Wedgwood and Bailey, 1988;Bourne et al, 1990;Henderson et al, 1992). Metaldehyde baits, in particular, are toxic to slugs on ingestion and cause increased slime secretion, immobilization and eventual death by loss of water (Bailey, 2002). Metaldehyde is highly specific and is not toxic to beneficial organisms such as earthworms, spiders, ants, millipedes, staphylinid and carabid beetles (Bieri, 2003).…”

Initial Evaluation of the Effectiveness of Selected Active Substances in Reducing Damage To Rape Plants Caused By Arion Lusitanicus (Gastropoda, Pulmonata, Arionidae)

“…Among the selected chemical compounds, only methiocarb and metaldehyde are registered as active substances of pelleted molluscicides generally used against slugs (Henderson and Triebskorn 2002;Bailey 2002;Kozłowski 2003). Copper compounds, such as copper carbonate, copper sulphate and others, may have molluscicidal properties (Gould 1962;Moens et al 1992).…”

Incidencia de los cebos a base de metaldehído y carbaril en la supervivencia y la reproducción de Folsomia candida

“…Tanto a nivel mundial como local, el manejo de estos organismos perjudiciales se realiza mediante control químico (Bailey, 2002;Iglesias, Castillejo y Ester, 2002;Mastronardi, 2006;Salvio, Faberi, López, Manetti y Clemente, 2008;Villarino, Manetti, López, Clemente y Faberi, 2011;Garavano et al, 2013), basado principalmente en el uso de cebos tóxicos granulados, formulados con un atrayente alimentario y un ingrediente activo (IA).…”
