For two decades, Phyllis Nduva, 72, has grown mangoes and citrus(柑橘属水果) in Wote, a town in Kenya’s eastern Makueni County. In the beginning, she only had to worry about(不得不担心) ordinary fruit flies(果蝇). She handled them simply, buying chemical pesticides(农药，杀虫剂) and spraying her trees whenever they appeared.
72岁的菲利斯·恩杜瓦在肯尼亚东部马库埃尼郡的沃特镇种植芒果和柑橘已有二十年。起初，她只需对付普通的果蝇。应对方法也很简单：买来化学农药，一发现果蝇就喷洒果树。
But then, in 2014, the false codling moth(假苹果蠹蛾) turned up(出现，露面) on her farm. The small brown creature had been causing havoc(大破坏，浩劫) in South Africa for years, and in 2007 it was spotted(发现，注意到) in Kenya.
但到了2014年，假苹果蠹蛾出现在她的农场。这种棕色小虫在南非肆虐多年，2007年在肯尼亚首次被发现。
Research into how to deal with the moth was continuing, but no one Nduva knew had information about how to stop it from spreading across her 8-hectare (20-acre) orchard.(关于如何对付这种蛾子的研究仍在继续，但恩杜瓦认识的人中，没有人知道如何阻止它在她的8公顷果园里蔓延。)
