| 中文摘要: |
| 烟粉虱Bemisia tabaci是许多大田和温室作物的重要害虫。其食性杂，寄主广泛，除通过取食植物汁液造成为害外，还传播病毒和引起植物生理异常。本研究使用“Y”型嗅觉仪研究了6种植物精油和4种植物水提取物对B型烟粉虱成虫的驱避效果。结果表明：5μL的剂量下，6种精油的驱避指数（RI）为：山楂（60.09）>花椒（48.53）>霍香正气水（2.83）>车前（-30.01）>紫苏（-36.13）>鱼腥草（-47.07）；在α=0.05水平下，除霍香正气水外，其他处理均与空白对照有显著差异。山楂和花椒等量混合的精油的驱避指数为4500；5 g/L的剂量下4种植物水提取物的驱避指数为：八角（41.28）>大蒜（39.37）>陈皮（39.09）>花椒（35.45）。 |
| 英文摘要: |
| Whitefly (Bemisia tabaci) is an important pest of many field and greenhouse crops. In addition to causing damage by feeding on plant sap,it has mixed diet, widely host and also spreads the virus and plant physiological abnormalities. This experiment focused on the repellent effects of six species of plant essential oils and four kinds of water extracts of plants on B biotype whitefly adults using the Y-olfactometer. The results showed that: at 5 μL dose, 6 oil repellency index (RI) is: Hawthorn(60.09)>pepper (48.53)>Chinese medicine (2.83)>Plantain (-30.01)>Basil (-36.13)>Houttuynia (-47.07); At the α = 0.05 level, except the Chinese medicine, other treatments were significantly different from the control. Hawthorn equal mixture of oil and pepper repellent index was 45.00; at 5 g/L dose, four plants extract water repellent index (RI) is: octagonal (41.28) > garlic (39.37) > Citrus (39.09) > pepper (35.45). |
