Lu Lizhi, a senior researcher with the Zhejiang Academy of Agricultural Sciences, told Bloomberg that the ducks are "biological weapons". He said that while chickens could eat about 70 locusts in one day a duck could devour more than three times that number. "Ducks like to stay in a group so they are easier to manage than chickens," he told Chinese media.

浙江省农业科学院高级研究员卢立志告诉彭博社：“鸭子是‘生物武器’，虽然鸡一天可以吃掉大约70只蝗虫，但一只鸭子可以吃掉超过这个数字三倍的蝗虫。鸭子喜欢成群结队，所以比鸡更容易管理。”

A trial involving the ducks will take place in China's western Xinjiang in the coming months, Mr Lu said. After that they will be sent to Pakistan's worst-affected areas of Sindh, Balochistan and Punjab provinces.

卢先生表示，在未来的几个月里，研究员将在中国西部的新疆对这些鸭子进行试验。之后，鸭子们将被派往巴基斯坦受灾最严重的信德省、俾路支省和旁遮普省帮助灭蝗。

However, a professor from the China Agriculture University, who is part of the delegation to Pakistan, questioned whether the ducks would be suited to the mainly arid conditions where the locusts are a problem.

然而，中国农业大学的一位教授(他是中国赴巴基斯坦救灾代表团的一员)提出了质疑：这些鸭子是否适合在严苛的干旱环境下进行灭蝗工作。
