    Abstract: 在抗蟲基因轉殖植物的研究上,利用於抗蟲的物質主要有蘇力菌內毒素、凝集素、酵素抑制物與酵素等四類。蘇力菌內毒素(毒蛋白)(δ-endotoxin of Bacillus thuringiensis)為蘇力菌殺蟲之主要成分,基因轉殖作物以殖入抗鱗翅目的cry1與抗鞘翅目的cry3最普遍。凝集素(Lectins)以雪花蓮凝集素(Snowdrop lectin, Galanthus nivalis agglutinin, GNA)為主,轉殖入煙草、馬鈴薯、稻米、小麥等作物,對於某些鱗翅目害蟲如蛾類與同翅目害蟲如蚜蟲、飛蝨類有抑制作用。酵素抑制物中常被利用的有豆類所含之蛋白?抑制物(Protease inhibitor)與澱粉?抑制物(α-amylase inhibitor)。蛋白?抑制物轉殖於水稻、小麥、菸草、馬鈴薯等,可防治飛蝨、蛾類等幼蟲,具不同程度之殺蟲效果;澱粉?抑制物主要研究於豆象類的防治。酵素類研究較多的是幾丁質分解?(Chitinase)與膽固醇氧化?(Cholesterol oxidase),幾丁質分解?為昆蟲或菌類產生的幾丁?,可破壞昆蟲中腸壁之圍食膜,擾亂取食與營養的吸收;膽固醇氧化?分離自細菌,可破壞昆蟲消化道之細胞膜,抑制昆蟲的消化作用。實際栽種推廣之抗蟲基因轉殖作物,均利用轉殖蘇力菌內毒素基因,如Bt棉花、Bt玉米、Bt馬鈴薯等,涉及其餘之抗蟲物質則多數仍在研發階段。
