中文摘要 | 根據三年多調查中部地區洋桔梗害蟲發生種類之結果顯示,共計發現4目6科10種的昆蟲、1目2科2種的蟎類及1種軟體動物。另以4種化學藥劑進行小黃薊馬 (Scirtothrips dorsalis Hood) 的防治試驗,結果在施藥後7天,4種化學藥劑之防治率均高達93% 以上,其中又以9.6% 益達胺 (Imidacloprid) 溶液3,000 倍的防治效果為最佳,但在施藥後14天,只有2.4% 第滅寧 (Deltamethrin) 水懸劑1,000倍的防治率仍可維持在87.6% 以上,防治效果最優。其次以5種非傳統農藥物質進行防治小黃薊馬試驗,結果顯示在施藥後7天,以木醋液加辣椒粉稀釋200 倍之防治效果最好,防治率為57.4% 。 |
英文摘要 | A three-year survey of insect pests on Eustoma grandiflorum in central Taiwan has recorded a total of 10 species of insects belonging to 4 orders and 6 families, 2 species of mites belonging to 1 order and 2 families, and 1 mollusk. In a control experiment on Scirtothrips dorsalis Hood, 7 days after application, all of the 4 tested chemical insecticides were able to provide an efficacy higher than 93%, with imidacloprid (9.6% S at 3,000x dilution) giving the best control. However, 14 days after application, deltamethrin (2.4% FP at 1,000x dilution) was the most effective, maintaining 87.6% of control. Another control experiment on Scirtothrips dorsalis using 5 non-chemical substances showed that 7 days after application, wood vinegar plus red pepper powder diluted at 200x gave the best control, with an efficacy of 57.4%. |
