Abstract:

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.
