Effect of transgenic crops on biodiversity
摘要
Abstract
Effect of transgenic crops on biodiversity is one of important environmental issues. Concerned experimental reports have been published recently. It was reported by Xia Jingyuan et al. that transgenic Bt cotton in field trial harms seriously the parasitic rate, emergence rate and quality of cocoon of Campoletis chlorideae and Microplitis sp.,and the dominant parasitic natural enemies of the larvae of bollworm (Helicoverpa armigera). Results on convincible experiments were published by entomologists, especially Losey's et al. results that transgenic pollen harms monarch larvae in his laboratory assay, published on Nature (399: 214, 20 May, 1999), caused strong repercussions worldwide.The U.S. government hold uncompromising stand on the effect of GMOs on potential ecological risks and public health, started to become flexible. USDA Secretary announced a new biotechnology advisory committee that will bring advice from a wide range of biotech stakeholders. Two U.S. processing companies that represent nearly half of the U.S. corn-processing market, announced that they will no longer accept transgenic corn varieties that are not approved by the EU. EU announced on May 21, the next day after publishing of Losey′s paper, that it would freeze its approval pending further investigation. UK recently announced it would wait 3 years before approving crops with built-in Bt; Austria, Luxembourg and Norway have banned the corn in spite of EU approval; Greece voted against the EU approval. Scientific and technological circles and the public opinions vary. Related Ministries and Agencies in our country have to pay enough attention, especially to strengthen the studies on the effect of GMOs on the potential ecological risks and public health and the monitoring after release of GMOs in the commercialized scale.关键词
