转基因植物对蜂类昆虫安全性

随着转基因植物的大规模商业化种植,其对蜂类等有益昆虫的影响成为研究转基因生物风险评估的主要内容。一方面蜜蜂等蜂类取食植物花粉,有可能直接接触到杀虫蛋白,产生毒性效应;另一方面转基因植物的性状、营养成分等可能发生变化,对蜜蜂的行为可能产生潜在影响。本文综述了目前转基因植物对蜂类昆虫安全性研究进展,并提出克服转基因植物对非靶标生物可能的负面效应的治理对策,以期对转基因植物生物安全性的研究提供科学依据。

Biosafety of transgenic plants to pollinating bees

With the commercial planting of genetically modified(GM) plants on a large scale,their potential impacts on some beneficial insects have become an important part of risk assessment of transgenic organisms.The flowers of many GM plants require bees for pollination,and some GM plants may be important food sources for bees.On one hand,when bees feed on the pollen of GM plants,they may contact toxic proteins directly.On another hand,the characteristics and ingredients of the nutrition in GM plants may be changed due to transfer of an exogenous gene, which may have some impacts on the behavior of bees.In this paper,the ecological risks of GM plants on bees and recent advances in this area are reviewed and some strategies of biosafety assessment are also proposed.
