Abstract

Essential oils (OEs) have emerged as an increasingly promising alternative for vector control to replace synthetic insecticides. This work aimed to evaluate the toxicity of essential oil from Citrus sinensis (pear orange) peels on sand flies of the species Lutzomyia longipalpis. The insects were exposed to different concentrations of the essential oil (100, 200, and 400 mg mL-1), and the survival rate after exposure was evaluated. The chemical characterization of the essential oil was carried out using gas chromatography coupled with mass spectrometry. The results showed that the essential oil from C. sinensis peels was toxic to sand flies at all concentrations evaluated, with a reduction in the survival rate with increasing concentration. Nine compounds were identified in the essential oil of C. sinensis, with d-limonene having the highest percentage of relative peak area of the total ion chromatogram. Further studies are needed to support the development of an efficient product that helps control these vectors.

柑桔精油对巴西内脏利什曼病病媒长掌Lutzomyia longipalpis的毒性研究。

精油已成为一种越来越有希望取代合成杀虫剂的病媒控制替代品。本研究旨在评价柑桔皮精油对长掌沙蝇的毒力。将不同浓度的香精油（100、200和400 mg mL-1）分别暴露于不同浓度的香精油中，观察其成活率。采用气相色谱-质谱联用技术对精油进行了化学表征。结果表明，在不同浓度下，金针叶挥发油对沙蝇均有毒性，且随着浓度的增加，其成活率降低。从芫荽挥发油中鉴定出9种化合物，其中d-柠檬烯在总离子色谱中相对峰面积百分比最高。需要进一步的研究来支持开发有效的产品，帮助控制这些媒介。

期刊介绍： The Brazilian Academy of Sciences (BAS) publishes its journal, Annals of the Brazilian Academy of Sciences (AABC, in its Brazilianportuguese acronym ), every 3 months, being the oldest journal in Brazil with conkinuous distribukion, daking back to 1929. This scienkihic journal aims to publish the advances in scienkihic research from both Brazilian and foreigner scienkists, who work in the main research centers in the whole world, always looking for excellence. Essenkially a mulkidisciplinary journal, the AABC cover, with both reviews and original researches, the diverse areas represented in the Academy, such as Biology, Physics, Biomedical Sciences, Chemistry, Agrarian Sciences, Engineering, Mathemakics, Social, Health and Earth Sciences.
