| 为明确适用于防治锈赤扁谷盗的植物精油种类及其用量，本试验采用拌粮密闭熏蒸法，比较23种植物精油对锈赤扁谷盗成虫熏蒸毒杀活性差异，从中筛选出作用效果较好的精油种类进行熏蒸毒力测定。通过二次筛选结果表明，大蒜与芥末精油对锈赤扁谷盗成虫具有明显的熏蒸毒杀作用。进一步的毒力测试结果表明，在24 h、48 h、72 h处理时间下，大蒜精油对锈赤扁谷盗成虫的LC50值分别为0.7827、0.7222、0.6478 μL/L，而芥末精油在相同处理时间条件下的LC50值分别为2.7581、2.6117及2.4619μL/L，大蒜精油对锈赤扁谷盗具有更强的熏蒸毒杀活性。 |
| 英文摘要: |
| The fumigant toxicity of 23 essential oils on adults of rusty grain beetle, Cryptolestes ferrugineus (Stephens)was investigated with the method of mixing oils with diet. The results proved that the fumigant toxicity activity of the essential oils of Allium sativum and Brassica nigra were better than that of the other 21 essential oils. The LC50 of rusty grain beetle fumigated by the essential oils of A. sativumunder the exposure time of 24, 48 and 72 hours were 0.7827, 0.7222 and 0.6478μL/L, respectively. While the LC50 of B. nigra under the same exposure time were 2.7581, 2.6117 and 2.4619μL/L, respectively. The fumigant toxicity of A. sativum on adults of rusty grain beetle was stronger than that of B. nigra. |
