瑞典科学家发现了一种遏制有害森林的松象鼻虫的方法:用一种闻起来象这种小甲虫的粪便的物质对树木进行处理。雌性松象鼻虫在树干的裂缝中产卵并用自己的粪便给它加上一层保护。科学家们制造出了一种气味和松象鼻虫粪便相似的化合物。试验表明用这种物质处理过的小松树没有遭到象鼻虫的破坏。瑞典南部一个森林试验公园的研究人员克里斯蒂娜·瓦尔
Swedish scientists have discovered a way to stop the deforestation of the weevil: the tree is treated with a substance that smells like the stink of this small beetle. Female pine weevil spawns in the cracks in the trunk and adds a layer of protection to it with their own excrement. Scientists made a compound that smells similar to the loose-weevil droppings. Trials have shown that small pine treated with this material has not been damaged by weevils. Cristina Val, a researcher at a forest test park in southern Sweden
