摘  要:
苜蓿夜蛾是影响我国大豆生产的重要食叶性害虫之一。在实验室和网室人工接虫条件下,对已获得的遗传稳定的双价抗虫转基因大豆抗苜蓿夜蛾能力进行了分析。结果表明,与对照非转基因大豆相比,抗虫转基因大豆株系T5-150和T5-195的叶片损害程度明显减轻;同时,苜蓿夜蛾幼虫食叶量显著下降、存活天数缩短,发育变慢,蛹化数也显著降低。表明抗虫转基因大豆抗苜蓿夜蛾能力显著提高。

摘  要:
Heliothis viriplaca is an important leaf-feeding insect for soybean.In this paper,resistance analysis of the stabilized binary insect-resistant transgenic soybean to H.viriplaca was conducted in vitro and in field conditions.The results showed that the insect-resistant transgenic lines T5-150 and T5-195 showed lower defoliation percentage than the non-transgenic ones.On the other hand,the H.viriplaca larvae feeding on the leaves of those two transgenic lines were characterized by less leaf consumption,greater larvae mortality,slower development,and less pupation ratio.Our results indicated that the resistance of the binary insect-resistant transgenic soybean to H.viriplaca was greatly enhanced.
