Thymol

thymolbehandlung_20170128

Dans les années 90, Le Centre de recherche apicole a contribué au screening de plus de 100 huiles essentielles et de leurs composants  pour leur potentielle utilisation dans la lutte contre varroa. Si les huiles de sauge, hysope et de thym se sont avérées intéressantes, seul le thymol a été utilisé dans des produits acaricides. Les traitements au thymol exigent peu de travail, et il existe sur le marché différentes préparations dont les avantages et les inconvénients sont présentés sous "Apilife VAR" - Un produit de lutte contre Varroa à base de thymol" et sous "THYMOVAR pour lutter contre Varroa jacobsoni".

Bien que le thymol engendre des résidus dans la cire et le miel, ceux-ci ne sont pas problématique d'un point de vue toxicologique.

L'utilisation de produits à base de thymol est en régression en Suisse depuis environs 2008 et les apiculteurs recourant à ces produits ont tendantiellement des pertes hivernales plus importantes que ceux utilisant l'acide formique par exemple.
