20.500.12556/RUL-162999 Invasive alien plant species aqueous extracts in a war against the granary weevil (Sitophilus granarius [L.]) – are they long-term effective or can they only win the Battle of Cannae? This study investigates the effectiveness of plant-based extracts in repelling the granary weevil (Sitophilus granarius), a common storage pest causing significant economic losses. The selected plant species (Canadian goldenrod, giant goldenrod, indigo bush, staghorn sumac, and tree of heaven), were examined for their repellent effects on weevils in grain samples. Surprisingly, the short-term repellent effects observed after 24 h diminished after 3 days, suggesting potential challenges for practical applications, especially in long-term grain storage. Temperature emerged as a significant environmental factor, influencing weevil behavior. Lower temperatures created an illusion of increased effectiveness, while higher temperatures accelerated weevil reproduction. Commercial product NeemAzal, despite its reputation for effectiveness, proved the least potent among all treatments, raising questions about its applicability in such cases. Progeny emergence tests indicated no significant differences between treatments, emphasizing the ineffectiveness of the extracts in sustaining long-term repellent effects. The study concludes that while plant-based extracts may offer short-term victories in pest control, their long-term efficacy remains uncertain. The complex interplay of factors, including temperature and humidity, highlights the challenges in developing sustainable and practical solutions for grain storage pest control, necessitating careful consideration by real-world users. plant-based extracts repellent effect storage pest control NeemAzal progeny emergence environmental factors sustainable pest management invazivne rastinske vrste vodni ekstrakt skladiščni škodljivci rižev žužek odvračala odvračalni učinek true false true Angleški jezik Slovenski jezik Članek v reviji 2024-09-30 14:25:54 2024-09-30 14:26:01 2024-10-05 03:48:28 0000-00-00 00:00:00 2024 0 0 9 str. art. 102434 Vol. 109 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 632 0022-474X 10.1016/j.jspr.2024.102434 209533699 1-s2.0-S0022474X24001917-main.pdf 1-s2.0-S0022474X24001917-main.pdf 1 82EC86C34671596F5464B6FD1D6F1548 4b9f7253737e9e36ba8aab382c60ab462ae9691c2074ade0824277c627e6a722 c480bd96-7fca-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=192501 https://www.sciencedirect.com/science/article/pii/S0022474X24001917 1 02df4116-7f27-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=192450 Biotehniška fakulteta 0 0 0
