Are flowers nature's master manipulators?

花真是大自然的 “操纵大师” 吗？

文字稿

They might look innocent, but some flowers are actually expert manipulators.

虽然看起来无害，但有些花实际上是 “操控高手”。

They use seriously sneaky tricks to attract pollinating insects, which carry tiny grains of pollen between flowers so the plants can reproduce sexually.

它们会用十分狡猾的伎俩来吸引授粉昆虫。这些昆虫会在花朵之间传递细小的花粉颗粒，从而帮助植物进行有性繁殖。

Some flowers like orchids have evolved to look or smell exactly like female insects, tricking males into trying to mate with them – but ending up covered in pollen instead.

其中一些花，比如兰花，进化出了与雌性昆虫几乎一模一样的外形或气味，诱骗雄性昆虫试图与它们交配，结果却沾满了花粉。

Hammer orchids go one step further. When a male wasp lands on it to mate, the flower slams him onto its pollen before letting him fly off to the next orchid.

铁锤兰则更进一步。当雄性黄蜂降落在花上并试图交配时，花朵会猛地将黄蜂弹向自己的花粉结构，然后再放开它，让它飞向下一朵兰花。

The 'corpse flower', sometimes called the world's smelliest plant, has evolved to smell like rotting flesh to attract pollinating insects that normally feed on dead animals.

“尸花”，有时被称为 “世界上最臭的植物”，它进化出了类似腐肉般的气味，以此吸引原本以动物尸体为食的昆虫前来传粉。

But it's not all one-sided.

不过，这也并不完全是单方面的利用。

Some flowers heat up to spread their scent – sometimes 20C or more above the air temperature – giving insects a warm place to stay on cold nights.

有些花会通过升高自身温度来帮助香气扩散，有时其温度甚至比周围气温高出 20 摄氏度以上，从而在寒冷的夜晚为昆虫提供一个温暖的栖息场所。

Nectar is a sugary liquid that attracts bees, and in some citrus and coffee plants it contains caffeine, giving the bees a memory boost so they keep coming back.

花蜜是一种能够吸引蜜蜂的含糖液体。而在某些柑橘或咖啡植物中，花蜜还含有咖啡因，可以增强蜜蜂的记忆力，让它们反复造访。

This may seem like controlling behaviour, but there are also chemicals in nectar that can help bees get rid of parasites or fungi growing on them.

这看上去或许像是花朵在 “操纵” 昆虫，但花蜜中的一些化学物质也能帮助蜜蜂清除身上的寄生虫或真菌。
