Influence of aromatic substances on locomotor activity of Deroceras agreste slugs

The global climate changes are causing an increase in the number and harmfulness of slugs. Deroceras agreste (Linnaeus, 1758) (Stylommatophora, Agriolimacidae) is a polyphagous phytophage that damages over 150 species plants, including many vegetables, cultivated berries grasses. Other than decrease yield, slugs cause deterioration consumer qualities products, promote infections intermediate hosts some parasites mammals birds. Thus, impose great losses on agricultural farming, therefore objective our study was determining variability locomotor activity D. reaction to aromatic substances. We determined repellent or attractive effects those substances for purpose further using obtained data plant protection. tested 52 their mixtures, which were conditionally divided into following groups: chemical solvents, extracts, aromatizers, organic acids synthetic cosmetic additives. Only dimethyl sulfoxide could be identified as attractant. All rest increased speed various degrees, but had no significant effect direction animals’ movement. Gasoline slugs’ movement by 3.20 times, xylene 4.56. most effective aromatizers moving avobenzone formic acid: first caused 2.83-fold speed, other 3.16-fold increase. one 13 changed during experiment – β-ionone. As with highest exerted tree bark Quillaja saponaria (3.64-fold) Aesculus hippocastanum extract (4.33-fold). Furthermore, together Capsicum frutescens, they mollusks in, used repellents. Synthetic additives hydrolyzed silk chrysalide oil greatest lcomotor (3.16 respectively). A total 78.6% moved away from oil, thus this may suggested repellent, well mousse de babassu cocamidopropyl betaine (84.6% 78.6%, Therefore, large amount another extent made move faster, them did not alter moving.
