中文摘要 | 評估四種動物(乳牛、水牛、山羊及綿羊)尿液、乳牛尿液混拌樹葉、一種結合昆蟲病原Beuveria bassiana及NPV的市售產品(Borerguard)對尼泊爾田間小菜蛾Plutella xylostella防治之功效。結果顯示,相對於控制組而言,以混拌動物尿液防治具顯著降低小菜蛾族群之效果,並較只使用單一動物尿液處理更能大幅降低小菜蛾在甘藍菜上的危害;然而在所有處理中又以Borerguard防治效果最為顯著。實驗亦測試兩種市售捕捉器(Wotta T trap and Delta sticky trap)在監測小菜蛾的效果,結果顯示Wotta T trap防治率顯著性高於Delta sticky trap。此研究顯示,使用天然成分能有效的害蟲防治,且有助於有機農業的發展。 |
英文摘要 | This study evaluated the efficacy of using the urine of four animals (cow, buffalo, goat, sheep), a urine-mix (cow urine and plant leaves) and Borerguard, a commercial entomopathogenic product containing Beuveria bassiana and NPV, against the diamondback moth (DBM), Plutella xylostella under field conditions in Nepal. The urine of these animals controlled the DBM significantly better than the control. Urine-mix had a better efficacy against the DBM. The plot treated by the urine-mix had the least number of cabbage leaves damaged, followed by the plot treated with cow urine and then the plot treated with goat urine. The use of Borerguard performed better than any of the other treatments. During the study, two commercial traps (Wotta T trap and Delta sticky trap) also were evaluated to monitor the DBM. The total number of DBMs trapped in the Wotta T trap was significantly higher than in the Delta sticky trap. This study revealed that nature-based products could be a viable option for organic farming. |
