A short extract from the Revolutionary Genius of Plants book.
The alkaloids contained in the nectar of acacia trees in Africa contain caffeine,
Nicotine and many others.
They not only affect ants' cognitive capacity as well as that of other pollinating insects that consume nectar,
But they also create addictions.
What has been discovered recently is that acacias,
Like many other species of these myrmecifolous plants,
Are capable of modulating the production of these substances within the extra-floral nectar so as to modify ants' behaviour.
Not only that,
Like experienced dealers,
Acacias must first attract the ants,
Luring them with this sweet nectar rich in alkaloids,
And then once the ants are highly addicted they can control their behaviour,
For example by increasing their aggressiveness or their mobility on the plant,
All this by modulating the amount and quality of the neuroactive substances present in the nectar from the acacia.
