Mr Claude,
I didn't read the complete article but here is an example of just one portion of this article about the benefit of essential oils for bees. If you are interested you can look it up or contact the researcher at the address that I have provided at the very bottom. And as you say, I hope that helps.

Notes about tracheal mites
We have found that several essential oils can either kill, or adversely affect varroa mites.
Essential Oils have Two Modes of Action:
1) Toxicity by direct contact:
When varroa mites contact essential oils such as wintergreen, patchouli, tea tree oil, et al., mixed into oil or grease, they are killed on contact?usually within a few minutes.
2) Impaired reproduction via feeding syrups containing essential oils:
When varroa mites feed on larvae that contain essential oils, their reproduction is interrupted. If the oil is strong enough, the females are unable to lay eggs. If the oils are in lower concentration, eggs
are layed, but development of immature mites is delayed; young mites do not reach maturity before the bees emerge from the cell; consequently, the immature mites die.
