Life went on and I started to travel the big wide world. I had always been fascinated by plants, particularly aromatic plants. However, no botanical studies with a promise of a reasonable future where available. I ended up getting a Ph.D in chemical ecology of insects, studying how plant chemicals influence insect behavior.
This is how it works:
herbivore insects, such as caterpillars, spend most of their life feeding on plants. While the herbivore is feeding, the plant is wounded by the mouth parts of the insect and emits all sort of chemicals. Carnivore insects are continuously searching their prey, i.e. the herbivore insects. Their sense of smell is so refined that they can perceive the odor of the wounded plant among all others and use it to find their victims.
Food is so much about chemistry and behavior, that I feel I have not changed my subject very much.
