摘要
考虑到使用精油是一种很有前景的技术,也是控制有害生物的一种有价值的替代方法,本研究旨在通过气相色谱法分析 Acanthospermum australe (Loefl.) O. Kunze(菊科)精油的化学特征,并评估 A. australe 和 Baccharis psiadioides (Less.) 精油的驱虫和杀螨效果。Kunze (菊科)精油的化学特性,并评估 A. australe 和 Baccharis psiadioides (Less.) Joch.Müll (菊科)精油对 Tetranychus urticae Koch (Tetranychidae)的驱虫和杀螨效果。在驱虫试验中,两种精油的浓度分别为 0.25、0.5 和 1%;在评估杀螨效果时,浓度分别为 10 μL/L(空气)和 20 μL/L(空气)。在 A. australe 的精油中发现了 8 种化合物,其中异丁酸百里酚酯(63.4%)是主要化合物,其次是百里酚(13.4%)和 2-甲基丁酸百里酚酯(4.96%)。结果表明,浓度为 0.5%的 A. australe 精油具有较高的驱避性,浓度为 1%的 B. psiadioides 精油的驱避性次之。当接触两种测试浓度的 A. australe 精油时,TSSM 的死亡率都超过了 90%,证明对这两种情况都有效。
The use of essential oils as an alternative for the control of Tetranychus urticae (Acari: Tetranychidae)
Considering that the use of essential oils is a promising technique and a valuable alternative in the control of unwanted organisms, this study aimed to chemically characterize the essential oil of Acanthospermum australe (Loefl.) O. Kunze (Asteraceae) through gas chromatography, as well as to evaluate the repellent and acaricidal effect of the essential oils from A. australe and Baccharis psiadioides (Less.) Joch.Müll (Asteraceae) against Tetranychus urticae Koch (Tetranychidae). For the repellency test, concentrations of 0.25, 0.5 and 1% were used for both oils, and concentrations of 10 μL/L(air) and 20 μL/L(air) to evaluate acaricidal effects. Eight compounds were identified in the essential oil of A. australe, with thymyl isobutyrate (63.4%) being the major compound, followed by thymol (13.4%) and thymyl 2-methylbutyrate (4.96%). The results demonstrated higher repellency to the essential oil of A. australe at a concentration of 0.5%, followed by B. psiadioides at a concentration of 1%. The mortality rate of TSSM exceeds 90% when exposed to both tested concentrations of the essential oil of A. australe proving effective in both cases.
期刊介绍:
The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics:
-Abiotic damage-
Agronomic control methods-
Assessment of pest and disease damage-
Molecular methods for the detection and assessment of pests and diseases-
Biological control-
Biorational pesticides-
Control of animal pests of world crops-
Control of diseases of crop plants caused by microorganisms-
Control of weeds and integrated management-
Economic considerations-
Effects of plant growth regulators-
Environmental benefits of reduced pesticide use-
Environmental effects of pesticides-
Epidemiology of pests and diseases in relation to control-
GM Crops, and genetic engineering applications-
Importance and control of postharvest crop losses-
Integrated control-
Interrelationships and compatibility among different control strategies-
Invasive species as they relate to implications for crop protection-
Pesticide application methods-
Pest management-
Phytobiomes for pest and disease control-
Resistance management-
Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
