true that, there are many things we are still coming to terms with regarding terps and other related Volatile Organic Compounds and the impacts on plant, animal, human, soil signaling/ interactions. Anyone called Lim would know about terps and hydrocarbons/ aromatics :) and the limonene being of particular interest to those seeking a deeper sleep for example, eg combining high Limonene tea while smoking is known to provide more consistent sleep. it wont help you to get off, but it will help you stay sleeping.
In Africa, terps killed herbivores in a drought, by making the enzymes in the gut of antelope for example, ineffective at digestion. So the animals died with a full stomach from starvation.
Just as there is a VOC to deter mites, there is another to attract them. Growers often make plants scream in subtle chemical ways only mites can hear. Mostly its humans that ring the dinner bell for pests and problems. But we are very good at inviting our own problems as humans and too slow to acknowledge its us fucking ourselves up
