17、ers, vastly increasing their income. The ants, so to speak, are on the march. （分数：30.00）_正确答案：()解析：如同其他地区一样，非洲芒果产区也饱受果蝇困扰，果蝇泛滥使芒果减产达 40%左右。事实上，非洲芒果中果蝇屡见不鲜，美国已下令对非洲芒果实施进口禁令，保护本国果园免受果蝇之害。但与此同时，非洲果农面对果蝇侵袭几乎无计可施。化学杀虫剂十分昂贵，即便买得起，杀虫剂灭蝇效果也不理想，因为当果农发现有果蝇后再喷洒往往为时已晚。 农业科学家也曾经尝试利用寄生蜂来防治果蝇虫害。但是，最常见的寄生蜂仅能杀死 1/20

18、的果蝇，躲过一劫的果蝇则继续为非作歹。还有一种方法是利用果蝇诱捕器，通过性诱剂引诱果蝇达到灭蝇目的。但是，这种诱捕器也是成本不菲。所以，大部分果农干脆趁芒果未全熟时提早采摘，这样果蝇危害性是小了，但是芒果也卖不出好价钱。 但是，如果芒果树上有大量工蚁安家的话，果农就彻底省心了。由范梅尔博士和同事在贝宁的几家果园开展的一项调查显示，每 30个芒果中，工蚁较多的芒果树所产芒果果蝇蛹还不到 1个，而没有工蚁的芒果树所产芒果果蝇蛹达到 77个。调查发现，工蚁觅食果蝇及其他害虫，灭蝇效果很好。 利用工蚁防治病虫害的做法在中国及其他亚洲国家已有数百年历史，澳大利亚也已予以采用。但是，范梅尔博士称，非洲芒果产区工蚁特别常见，所以这种灭蝇方法对非洲特别适用，而且操作起来不需要多少培训或资金。果农只需要找到一个合适的蚁巢，用一根绳子将其引向果树，这样工蚁很快就可以找到果蝇。范梅尔博士说，在布基纳法索培训果农只需一天时间，这些果农今后不再需要杀虫剂灭蝇，同时，还可以向热衷有机食品的欧洲消费者推销他们的有机芒果，从而大大提高收入。打个比方说，工蚁现在正向果蝇“全面开战”。三、Part B Choice of Two(总题数：0，分数：0.00)四、Section Chinese-En(总题数：0，分数：0.00)
