Abstract
Abstract More and more frequently beer is used as an attractant in traps to eliminate the slug Arion lusitanicus auct. non-Mabille. The smell of beer is not indifferent to animals. Hence it is highly probable that it affects the physiological processes in the slug’s body. The aim of our study was to examine whether the smell can induce changes in respiration activity (measured as CO2 emission) of adult individuals of Arion lusitanicus. The results showed that all the tested brands of beer caused an increase in CO2 emission. Furthermore, in all the samples of studied brands of beer, this increase in CO2 emission correlated negatively to the content of the following compounds: acrylic acid N- hydroxysuccinimide ester, decanoic acid, (9Z,12Z)-9,12-octadecadienoic acid, 2-(acetyloxy)-1- [(acetyloxy)methyl]ethyl ester, bicyclo[4,1,0]heptane and ethyl caprylate.
