Nowadays, Acrobasis advenella is considered a pest of the highest economic significance in black chokeberry plantations, negatively affecting the quantity and quality of fruits. The aim of this study was to investigate the effect of Satureja hortensis essential oil and its main constituent, carvacrol, on the life cycle and physiology of A. advenella. The metabolic activity of both preparations was evaluated against insect α- and β- glucosidase, catalase, peroxidase and polyphenol oxidase. The results showed S. hortensis essential oil and carvacrol, are characterized by insecticidal activity against A. advenella larvae. It found an increase in catalase activity in A. advenella homogenates under the influence of carvacrol and an induction of polyphenol oxidase by S. hortensis EO with no changes in POX activity. Also, it was shown that the activity of α- and β-glucosidase significantly increased in larvae fed on inflorescences treated with the essential oil and carvacrol. These preparations particularly strongly affected β-glucosidase activity in the insect homogenates. S. hortensis essential oil reduced emergence the longevity of moths. The obtained results suggest that S. hortensis essential oil and carvacrol can be useful in protecting organic crops of black chokeberry but essential oils may be more effective biopesticides than their active ingredients separately.
如今，Acrobasis advenella 被认为是黑穗醋栗种植园中经济意义最重要的害虫，对果实的数量和质量都有负面影响。本研究旨在研究香薄荷精油及其主要成分香芹酚对 A. advenella 生命周期和生理学的影响。评估了这两种制剂对昆虫α-和β-葡萄糖苷酶、过氧化氢酶、过氧化物酶和多酚氧化酶的代谢活性。结果表明，香薄荷精油和香芹酚对 A. advenella 幼虫具有杀虫活性。研究发现，香芹酚影响 A. advenella 匀浆中过氧化氢酶的活性增加，并诱导多酚氧化酶，但过氧化物酶的活性没有变化。此外，还表明，用精油和香芹酚处理过的花序喂养的幼虫中，α-和β-葡萄糖苷酶的活性显著增加。这些制剂特别强烈地影响了昆虫匀浆中的β-葡萄糖苷酶活性。香薄荷精油降低了蛾的羽化和寿命。研究结果表明，香薄荷精油和香芹酚可用于保护黑穗醋栗的有机作物，但与单一活性成分相比，精油可能是更有效的生物农药。
