Abstract

Five Himalayan plants namely, Acorus calamus, Cedrus deodara, Aegle marmelos, Tagetes minuta and Murraya koenigii were used for the extraction of essential oils through hydrodistillation and the major volatile constituents as identified by GC and GC-MS techniques were β-asarone (91.1%), β-himachalene (45.8%), limonene (59.5%), Z-ocimene (37.9%) and α-pinene (54.2%), respectively. Essential oils were tested for their insecticidal properties against larvae of diamondback moth, Plutella xylostella (L.) (Lepidoptera: Yponomeutidae). Results showed that A. calamus was most toxic (LC50 = 0.29 mg mL(-1)) to P. xylostella followed by C. deodara (LC50 = 1.08 mg mL(-1)) and M. koenigii (LC50 = 1.93 mg mL(-1)) via residual toxicity bioassay. Per cent feeding deterrence index and growth inhibition was significantly higher in A. calamus (42.20 and 68.55, respectively) followed by C. deodara (35.41 and 52.47). In repellent activity studies, C. deodara showed high repellence (64.76%) followed by A. calamus (55.05%).

摘要

选取了五种喜马拉雅植物，即菖蒲、雪松、印度枳、小花万寿菊和印度九里香，通过水蒸馏法提取精油，采用气相色谱（GC）和气相色谱-质谱联用（GC-MS）技术鉴定出的主要挥发性成分分别为β-细辛脑（91.1%）、β-喜玛拉雅烯（45.8%）、柠檬烯（59.5%）、Z-罗勒烯（37.9%）和α-蒎烯（54.2%）。对小菜蛾（Plutella xylostella (L.)，鳞翅目：麦蛾科）幼虫测试了这些精油的杀虫特性。结果表明，通过残留毒性生物测定法，菖蒲对小菜蛾毒性最大（LC50 = 0.29 mg mL⁻¹），其次是雪松（LC50 = 1.08 mg mL⁻¹）和印度九里香（LC50 = 1.93 mg mL⁻¹）。菖蒲的取食抑制率和生长抑制率显著更高（分别为42.20和68.55），其次是雪松（35.41和52.47）。在驱避活性研究中，雪松表现出较高的驱避性（64.76%），其次是菖蒲（55.05%）。
