中文摘要 | 在實驗室內,分別測定化學肥、有機肥及殺蟲劑等對Steinernema abbasi之感染期第三齡蟲 (infective juvenile, IJ) 持效力之影響。以線蟲在32日內引起的大蠟蛾 (Galleria mellonella) 末齡蟲死亡率為評估在含肥料的土壤中線蟲持效力的標準,而在大蠟蛾幼蟲体內建立的線蟲數目則做為殺蟲劑試驗之依據。土壤含未腐熟有機肥時,S. abbasi的持效力明顯降低,但若土壤含0.5~2.0% 之牛糞、豬糞及雞糞等腐熟有機肥時,該線蟲得以維持適當的持效力至32日止。土壤含化學肥時,S. abbasi之殺蟲效力會受到嚴重的負面影響。S. abbasi與歐滅松 (omethoate)、芬化利 (fenvalerate)、百滅寧 (permethrin)、畢芬寧 (bifenthrin)、歐殺松 (acephate) 及賽滅淨 (cyromazine) 等六種常用於蔬菜之殺蟲劑具適當的相容性,且此等藥劑對線蟲在土壤之持效力影響不顯著。 |
英文摘要 | Effects of insecticides and chemical and organic fertilizers on the persistence of infective juveniles (IJ) of the entomopathogenic nematode, Steinernema abbasi, in soil were examined in the laboratory. Larval mortality of the greater wax moth, Galleria mellonella[/i], within 32 days caused by the nematode was regarded as the criterion for evaluating nematode persistence in the soil containing fertilizers, while the number of nematodes in insect larvae was regarded as the criterion for the insecticide experiments. In soil containing nondecomposed organic fertilizers, nematode persistence was low; whereas in soil containing 0.5%~2.0% decomposed organic fertilizer made of cattle, pig, or chicken feces, nematodes persisted for 32 days. However, in soil containing chemical fertilizers, nematode persistence was severely hampered. Steinernema abbasi was found to be compatible with six commonly used insecticides in vegetables, i.e., omethoate, fenvalerate, permethrin, bifenthrin, acephate, and cyromazine. These insecticides did not markedly affect nematode persistence in the soil. |
