| 摘 要： | 采用点滴法、熏蒸法等生物测定的常规方法测定了丁香酚(Syzygium aromaticum)对世界性仓贮害虫赤拟谷盗(Tribolium castaneum (Herbst))的生物活性作用.结果表明,丁香酚能抑制赤拟谷盗的生长发育,不同发育时期的赤拟谷盗卵对丁香酚的敏感程度不同;在(31±1) ℃,相对湿度为50%～85%的环境条件下,发育72 h左右的赤拟谷盗卵对丁香酚最敏感,6 μL/mL丁香酚即能完全抑制卵的孵化;丁香酚对赤拟谷盗的幼虫和成虫均有显著的触杀作用,其对幼虫和成虫的致死中浓度(LC50)分别为218.999 9 μL/mL和363.077 4 μL/mL,表明幼虫对丁香酚比成虫对丁香酚更敏感;丁香酚对赤拟谷盗成虫具有明显的驱避作用,对幼虫和成虫也有一定的熏蒸致死作用,用2 μL/mL丁香酚处理赤拟谷盗成虫3 h,对赤拟谷盗成虫的驱避率可达到93.3%,即可达到最高驱避级别V级. |

| Abstract: | Eugenol is one of main constituents of medicinal material Syzygium aromaticum,and Tribolium castaneum(red flour beetle,RFB) is one of the most important stored-product insects.The bioactivity of eugenol on RFB is tested with normal bioactivity technique such as topical application and fumigant methods.The results show that treated with eugenol oil,the egg of RFB can not complete its life history.Furthermore,different developmental stages of RFB egg have different sensitivity to eugenol.Under the condition o... |
