Abstract:

Deroceras reticulatum (Müller) is the most destructive slug pest of arable crops in Britain. Control on a field scale relies heavily on molluscicide pellets. These are often only partially effective; considerable economic loss and collateral damage still occur. More effective targeting of pellets will depend on accurate predictions of damage severity through a better understanding of population dynamics, reliable estimates of surface activity and behavioural studies to evaluate current control strategies. Lifecycle parameters of D. reticulatum were studied. There was considerable variation in

Abstract:

Slugs are important pests in many agricultural crops and potential biological control agents are being studied as an alternative to molluscicide application. The role of the carabids Pterostichus madidus (Fabricius) and Nebria brevicollis (Fabricius) as predators of the slug Deroceras reticulatum (MUller) was examined in the laboratory. These generalist beetle species were only capable of killing small, healthy slugs (<0.1 ig) as they were unable to overcome the defence mucus production of larger slugs. Dead slugs were scavenged in preference to killing healthy slugs. The relatively high propo

Abstract:

Significant developments in gastropod endocrinology since 1969 are reviewed. The anatomy of the CNS, distribution of nerves and the general plan of the vascular system in Deroceras reticulatu m is described. The central ganglia are encased in a thick perineural sheath, a matrix of collagen in which muscle fibres, blood vessels, granular cells, pigment cells and vesicular cells are embedded. The fine structure of the blood vessels supplying the CNS suggests that metabolic requirements reach the neurones by diffusion from these vessels. Dorsal Body tissue (DBT) occurs on the cerebral ganglia and

Abstract:

The oleoresin exudates from two species of Commiphora trees, and their extracts, were evaluated as novel methods of controlling terrestrial molluscs. Various test methods were employed including terraria trials, leaf disc assays, caged field trials and spray trials. Laboratory terraria trials with C. molmol (myrrh) and C. guidotti (opoponax) oleoresins, showed them to be effective repellent barriers against the terrestrial molluscs Deroceras reticulatum, Arion hortensis and Helix aspersa. Solid repellent barriers comprised of reduced amounts of myrrh oleoresin, mixed with inert materials (sawd

Abstract:

The field slug Deroceras reticulatum is a major pest in UK agriculture and amidst growing concern and regulatory pressures surrounding chemical molluscicides, innovation is required to advance the current repertoire of slug controls. This study set out to investigate the bacteria associated with D. reticulatum to assess their importance to the slug and potential as a target for biological control. Slug gut bacterial isolates identified using the phenotypical API system (BioMérieux) and 16S rRNA gene sequencing, were mainly soil-dwelling organisms of the phyla Proteobacteria and Bacteriodetes

Abstract:

Malgré des inconvénients rédhibitoires, l’utilisation de molluscicides reste prédominante dans les stratégies de lutte contre les gastéropodes terrestres, une situation qui appelle au développement d’alternatives. Bien que les gastéropodes terrestres reposent essentiellement sur la chémodétection pour la réalisation d’un grand nombre d’interactions capitales avec leur environnement, leur perception de la prédation reste largement méconnue malgré son importance écologique. Nous avons donc étudié l’altération de comportements de maintenance chez deux espèces de gastéropodes terrestres nuisibles,

Nematodes of the genus Phasmarhabditis (Nematoda: Rhabditidae) are world-wide distributed molluscs´ parasites. Species P. hermaphrodita is the only commercially produced bio-agent for slug control. The aim of this thesis is to evaluate some ecologic characteristics of three newly described species of the genus Phasmarhabditis (P. bohemica, P. bonaquaense a P. apuliae) in polyxenic and monoxenic cultures. Three bacterial isolates, Pseudomonas sp., Acinetobacter sp. and Flavobacterium sp. were chosen for testing the monoxenic cultures. The growing ability of tested nematodes, the effect on the q
