20.500.12556/RUL-169243 Effectiveness of different beer types in slug trapping a two-year field study on Arion vulgaris Moquin-Tandon and Limax maximus L. Slugs are significant agricultural pests, causing extensive crop damage and economic losses. While chemical molluscicides are commonly used for control, concerns about their environmental impact have driven interest in alternative methods, including beer traps. This study evaluated the effectiveness of different beer types as attractants for slug trapping in field conditions over two consecutive years (2022–2023). Five types of beer—Union Lager, Paulaner Weissbier, BrewDog Punk IPA, Guinness Draught, and Chimay Blue—were tested alongside ethanol (10%) and a control treatment. The results demonstrated that Paulaner Weissbier and Union Lager were the most effective attractants, followed by Guinness Draught and Chimay Blue, while BrewDog Punk IPA had moderate effectiveness. Ethanol (10%) and the control treatment failed to attract slugs, confirming that volatile compounds, rather than alcohol alone, drive slug attraction. Gas chromatography–mass spectrometry (GC-MS) analysis revealed that Paulaner Weissbier contained high levels of isoamyl acetate and limonene, while Union Lager exhibited elevated ethyl esters, which likely contributed to their effectiveness. Environmental factors influenced slug activity, with higher temperatures correlating with increased slug capture rates, while precipitation had no significant effect. These findings highlight the role of fermentation-derived volatile compounds in slug attraction and suggest that optimizing beer traps based on beer composition and environmental conditions could improve their effectiveness as a non-chemical slug control method. Future research should explore the long-term stability of beer attractants, the potential of synthetic formulations, and alternative yeast-based attractants to enhance slug management strategies. slug control beer traps gastropod attractants non-chemical pest management volatile compounds GC-MS analysis integrated pest management IPM environmental factors fermentation by-products alternative molluscicides nadzor polžev pivske pasti atraktanti za polže nekemično zatiranje škodljivcev hlapne spojine GC-MS analiza integrirano zatiranje škodljivcev okoljski dejavniki stranski proizvodi fermentacije alternativni mehkužcicidi true false true Angleški jezik Slovenski jezik Članek v reviji 2025-05-20 11:25:40 2025-05-20 11:25:47 2025-05-21 03:57:17 0000-00-00 00:00:00 2025 0 0 12 str. issue 10, [article no.] 1097 Vol. 15 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 632.93 2077-0472 10.3390/agriculture15101097 236449027 Effectiveness_of_Different_Beer_Types_in_Slug_Trapping__A_Two-Year_Field_Study_on_Arion_vulgaris_Moquin-Tandon_and_Limax_maximus_L_.pdf Effectiveness_of_Different_Beer_Types_in_Slug_Trapping__A_Two-Year_Field_Study_on_Arion_vulgaris_Moquin-Tandon_and_Limax_maximus_L_.pdf 1 1734AC909C1AA27DF1F19BF2F8853DDC f0c53c66123202784f441699e9821250ac0fc94761b95f49b454543afc5bdcf8 62c2d44e-355b-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=210490 https://www.mdpi.com/2077-0472/15/10/1097 1 28c3cd97-355b-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=210489 Biotehniška fakulteta 0 0 0
