Abstract

Plants of the Artemisia L. genus are known for several biological effects. However, comprehensive studies on their insecticidal activities, particularly focusing on the activity of the main metabolites, are still limited.

This study examines the properties of the essential oil (EO) extracted by Artemisia campestris L. subsp. campestris (ACC), collected in Pantelleria island, Italy. This study focused on the insecticidal activity of ACC, evaluating the phytosanitary potential of two isolated natural alkynes: capillene and 2,4-pentadiynylbenzene.

The EO was studied by GC-MS and 2D-NMR tecniques revealing that it was rich in alkyne compounds (59.04%), with capillene being the predominant component (40.03%). The HSQC study not only highlighted the clear presence of alkyne derivatives and β-pinene, but confirmed the identification carried out by GC and GC-MS. At the same time, the promising insecticidal efficacy of ACC against Spodoptera littoralis (Boisd.) larvae was found.

The study demonstrated that ACC is a promising candidate for botanical insecticide development due to its effectiveness against S. littoralis larvae and its relative safety for non-target organisms.

2,4-戊二苯基苯和毛细烯对沿海夜蛾幼虫和非目标生物的光谱研究及杀虫效果

蒿属植物以几种生物效应而闻名。然而，对其杀虫活性的全面研究，特别是对其主要代谢物活性的研究仍然有限。本研究考察了青蒿（Artemisia campestris L. subsp）提取的精油的性质。campestris (ACC)，采自意大利Pantelleria岛。本研究主要研究了ACC的杀虫活性，评估了两种分离的天然炔：毛细烯和2,4-戊二苯的植物检疫潜力。通过GC-MS和2D-NMR对其进行分析，发现其富含炔类化合物（59.04%），以毛细烯为主要成分（40.03%）。HSQC研究不仅明确了炔类衍生物和β-蒎烯的存在，而且证实了GC和GC- ms的鉴定。同时，还发现了ACC对沿海夜蛾（Boisd.）幼虫的杀虫效果。该研究表明，ACC对滨海海蛾幼虫有效，对非目标生物相对安全，是开发植物性杀虫剂的一个有希望的候选物。

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.
