据中国农业新闻网消息,联合国粮农组织10月28日表示,一项新研究成果表明,世界上对农业最具破坏性的4种有害果蝇实际上是同一物种。这一发现或许能够促使农产品贸易方面的某些限制放宽。为防范有害外来物种入侵,许多国家限制农产品进口或严加检疫,果蝇是重点防控对象。多年来,人们将危害最大的果蝇分类为东方果蝇、菲律宾果蝇、入侵果蝇和亚洲木瓜果 According to China Agriculture News, the UN Food and Agriculture Organization said on October 28 that a new study shows that the four most harmful fruit flies in the world that are most devastating to agriculture are in fact the same species. This finding may be able to ease some of the restrictions on trade in agricultural products. In order to prevent the invasion of harmful alien species, many countries restrict the import of agricultural products or severely quarantine, and the fruit flies are the key prevention and control targets. For many years, the most damaging fruit flies were classified as Oriental fruit flies, Philippine fruit flies, invasive fruit flies and Asian papaya fruit
