Tests were conducted on three fixed dosages i.e., 4,000-, 32,000- and 128,000-fold dilution, from original formulations. In the susceptible strain, three designated dosages caused 96~100%, 58~97% and 41~81% mortalities in contrast to 16~100%, 0~65% and 0~31% mortalities in 4 field strains.由三重、溪湖、西螺及路竹採得之小菜蛾以六種商品化之蘇力菌配方(Thuricide、Dipel 2X、Javelin、MVP、Xentari及Turex)測試其感度,並與室內之感性品系進行比較,發現所測試的三個稀釋濃度(4,000倍、32,000倍及128,000倍)下,感性品系之死亡率分別為為96~100%、58~97%及41~81%。而田間品系在相同的三個濃度下,死亡率則為16~100%、0~65%及0~31%,顯示蘇力菌對田間小菜蛾之防治效率已經降低,而證實蘇力菌之抗藥性確實已經發生,尤其以在本省使用歷史最長之Thuricide之抗性最高,其抗性比為118.3。 |
