| 摘要: |
| 采用三角瓶熏蒸法或熏蒸盒法,测定了松油烯-4-醇对小菜蛾、粘虫、棉铃虫的3龄幼虫及家蝇、玉米象、赤拟谷盗成虫的熏蒸毒力。结果表明,松油烯-4-醇对不同种类昆虫的熏蒸毒力有较大差异；对小菜蛾、粘虫、家蝇的熏蒸毒力较高,其LC50值分别为1.832 1,5.347 3,2.951 1 μL/L,而对玉米象、赤拟谷盗、棉铃虫的熏蒸毒力较低；不同种类试虫的症状反应有所差异,但中毒反应过程都包括兴奋、痉挛、麻痹昏迷、死亡或复苏等几个阶段；鳞翅目昆虫小菜蛾、粘虫和棉铃虫大量吐胃液现象明显,家蝇有忌避和被迅速击倒现象,中毒后部分试虫有复苏能力。 |

| Fumigation effect and symptom of terpinen-4-ol against several insects |
|
|
| Abstract: |
| The fumigation effect of terpinen-4-ol is very effective against many kinds of insects.To 3rd-instar larvae of Plutella xylostella,Leucania separata and Helicoverpa armigera,LC50 was 1.832 1,5.347 3,46.380 1 μL/L,respectively.To the adults of Musca domestica,Sitophilus zeamais and Tribolium castaneum,LC50 was 2.951 1,27.968 8 and 136.497 5 μL/L,respectively.Symptom was characterized by a definite sequence of events,starting with excitation,convulsion,paralysis,and death.But some insects in paralysis could recover at a lower dose. |
