摘要: 斑翅果蝇因其传播速度快,传播范围广的特点对全球水果产业造成了严重危害。本文利用4种蒿属植物精油,即华北米蒿精油、猪毛蒿精油、莳萝蒿精油和黄花蒿精油,对斑翅果蝇开展了生物防治研究,系统探讨了4种精油的杀虫活性。本研究,旨在挖掘新型环保的植物源杀虫剂。利用熏蒸、驱避和对幼虫的致死效应,探究4种精油对斑翅果蝇的生物活性;采用气相色谱-质谱联用仪(GC-MS)对4种蒿属精油的化学成分进行分析。熏蒸试验表明4种精油均具有较好的杀虫特性,其中华北米蒿精油对果蝇的熏蒸效果最好,LC50为1.421 μL/mL,莳萝蒿精油次之,LC50为3.499 μL/mL,黄花蒿精油效果最差;驱避试验表明华北米蒿精油驱虫效果最佳,驱虫率为86%,黄花蒿精油驱虫效果最差,驱虫率为50%;对幼虫的致死效应表明,在猪毛蒿精油作用下,斑翅果蝇幼虫致死率达到70%,莳萝蒿精油效果最差,幼虫死亡率为40%;GC-MS分析结果表明,四种精油共82种成分,并且β-石竹烯、4-萜品醇和1,8-桉叶素是4种精油中的常见化合物。综上研究结果表明,四种精油对斑翅果蝇有较强的杀虫效果,值得进一步研究,并为开发绿色无公害的植物源杀虫剂奠定了理论基础。

Abstract: Drosophila suzukii Matsumura is a serious threat to fruit production around the world due to its fast spread and wide distribution. Essential oils of four Artemisia plants including A. giraldii, A. scoparia, A. anethoides, and A. annua were evaluated for their biological activities against D. suzukii, aiming to exploit new environmentally friendly plant-derived insecticides. The insecticidal activity of the four essential oils against D. suzukii was determined by fumigation test, repellency test and larval mortality test; the chemical composition of the four essential oils was analyzed using gas chromatography-mass spectrometer (GC-MS). The fumigation test showed that the four essential oils all had good insecticidal activities against D. suzukii, and the fumigation activities of A. giraldii essential oil was the best, with LC50 value of 1.421 μL/mL, followed by A. anethoides essential oil, with LC50 value of 3.499 μL/mL, and A. annua essential oil came at the last. The repellent test showed that A. giraldii essential oil was of the highest repellent activities, with repellency indices of 86%, and the A. annua oil was the worst, with repellency indices of 50%. The larval mortality test showed that A. scoparia essential oil resulted in 70% mortality of D. suzukii larvae, while A. anethoides essential oil was the least effective, with only 40% larval mortality. GC-MS analysis showed that there were 82 components in the four essential oils, and β-Caryophyllene, Terpinen-4-ol, and 1,8-Cineole are common compounds in the four essential oils. The above results indicate that the four Artemisia essential oils have the potential to be developed as an insecticide for D. suzukii. This research paves a theoretical foundation for the development of green pollution-free plant-derived pesticides.
