重组杆状病毒杀虫剂的生物安全性

The biosafety of recombinant baculovirus insecticides

分别就重组杆状病毒杀虫剂对捕食性天敌和寄生性天敌的影响、与其它生物间的基因重组和生态效应等问题进行了综述。研究成果表明 ,重组病毒的生态适应性降低 ,因而对生态环境以及捕食性和寄生性天敌等非靶标生物种类的危险性也大大降低。但重组病毒也不是绝对安全的 ,对其生物安全性还要进行长期、深入全面地分析和研究。

This paper reviews the effect of recombinant baculovirus insecticides on the predatory and parasitic natural enemies of insect pests，the recombinatio n between recombinant baculovirus and the genome of other organisms and the ecol ogical effect of recombinant baculovirus. So far studies have shown that compare d with wild\|type baculoviruses，the ecological fitness of recombinant baculovir u ses is reduced，thereby reducing the risks to ecosystems and non\|target organis m s such as predators and parasites. However，the use of the recombinant baculovir uses as biocontrol agents is not risk\|free. The long term biosafety of recombin ant baculoviruses needs to be profoundly and completely studied.
