Abstract
葱潛蠅（Phytobia cepao Hering）為石蒜科菜類，如四季葱、洋葱、北葱、西螺葱、大蒜及韮菜等之主要害蟲，在臺灣全年均有出現，惟其猖獗為害時期，為四至十月問高溫期。幼蟲潛食葉部，偶而潛食鱗莖及韮菜花柄，使此等部份發生腐敗，失卻商品價值。被害之植株通常生長緩慢、萎縮，影響產量。目前本省一般栽培者多採用高毒性殺蟲劑，如Parathion. PM. EPN等防治，且每隔7天左右防治一次，不但成本高，且常引起農藥殘留之嚴重公害問題。
Stone leek leafminer (Phytobia cepae Hering) is a major insect pest of Spring onion, Chinese leek, Onion, Garlic and other Amaryllidaceae crops in Taiwan. Parathion, a combination of Parathion-Malathion, or EPN sprays are frequently used by the farmers in the warm season during April to October every year. However, the control expenses seems rather high because of repeat applications, long growing period of Spring onion or other Amarylliaceae crops have to be applied every 7-10 days during the 4 growing months.
The test was conducted at Hsiang-Shan, Hsin-Chu from July to November, 1970 to determine the effectiveness of soil treatment with 8 different granular insecticides for the control of phytobia cepae Hering on Spring onion. Rates of 1.0, 1.5 and 2.0kg a.i. per hectare were tested respectively for each granular insecticide and the total 24 treatments and one control were designed. as Randomized Complete Block Design with four replications.
