中部地區洋桔梗害蟲種類調查及其防治研究
A Survey of Pests on Eustoma grandiflorum and Their Control in Central Taiwan
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%。

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%.
