摘要

本試驗選用菸草浸液、無患子液、稻殼炭化乾餾液、精餾竹酢液、苦楝油和樟腦油，對棉蚜（Aphis gossypii）和蔥薊馬（Thrips tabaci）進行測試，並觀察其死亡情形。室內測試結果顯示棉蚜在被噴灑濃度為10％，4％，2％，1.3％，及1％的菸草浸液後72小時，死亡率皆可達99％以上，顯示菸草浸液具有良好的防治棉蚜效果，但與竹酢液混合使用則會降低菸草浸液之殺蟲效力；另一測試結果顯示1％無患子液可造成蔥薊馬死亡率達91.7％，而1％及4％的樟腦油處理薊馬之死亡率分別為88.8％與84.9％，2％菸草浸液則可使蔥薊馬死亡率達94.4％。田間試驗結果顯示以1％菸草浸液加上0.4％苦楝油和1％無患子液之混合液處理對韭菜之蔥薊馬防治效果最佳。

Tobacco extracts, Rice hull vinegar, bamboo distillation, chile distillation, chile extracts, soapberry extracts, neem oil, and camphor oil were tested to control Aphis gossypi and Thrips tabaci. The mortality was counted after treatment. Results revealed that the mortality of cotton aphids treated with tobacco extracts of 10%, 4%, 2%, 1.3%, and 1% concentration was higher than 99% at 72 hours after treatment. On the other hand, mortality of Thrips tabaci treated with 1% soapberry, 1% and 0.4% camphor oil, and 2% tobacco extracts were 91.7%, 88.8%, 84.9% and 94.4%, respectively. In field trial, the mixture of 0.4% neem oil and 1% soapberry with 1% tobacco extracts could reduce the Thrips tabaci density effectively.
