摘要
在时间序列过程中,转基因741杨对目标害虫鳞翅目食叶害虫表现出持续的抗性,其数量明显减少,高抗和中抗741杨之间差异不大。研究表明,转基因741杨对目标昆虫和非目的植食性害虫存在负效应,而对天敌和中性节肢动物组成和发生无明显负作用。因而在制定害虫综合治理策略和途径上宜采取与对照741杨不同的措施,抗性株系应以生态调控为主。
During the investigations in several years, the transgenic insect-resistance hybrid poplar 741 presented a continuance resistance on target pests, lepidopter, causing significant decrease in pest populaton. There was no obvious impact on the population of pest between high and medium insect-resistance hybrid poplar 741 stands. Transgenic insect-resistance hybrid poplar 741 had negative effect on target and non-target phytophagous pests, but had positive effect on natural enemies and neutral arthropod. These results demonstrated that different control strategy and measure should be taken in integrated pest management of transgenic insect-resistance hybrid poplar 741, compared to those of the parental hybrid poplar 741, and the high insect-resistance clones had better be used as plantations for the ecological regulation.
