Abstract

Natural medicines such as formic acid, oxalic acid, thymol and menthol have recently been used as alternative treatments against the honey bee parasitic mite varroa. The aim of this study was to observe and examine their impact on Heat Shock Proteins (HSP 70) in the brain tissues of bees. For this purpose, seven different treatment groups were created using various concentrations and administrations of formic and oxalic acid and thymol-menthol mixtures, including positive (untreated) and negative controls. The results showed that in the groups exposed to the varroa treatments, HSP 70 results were lower than those of the non-treated groups. HSP 70 results were lowest in the thymol-menthol mixture exposed group among the treated groups. We conclude that it would be more beneficial to prefer natural medicines against varroa, which lead to lower HSP 70 results which are the molecular determinants of stress.
Recientemente se han usado las medicinas naturales como el a ́cido fo ́rmico, el a ́cido oxa ́lico, el timol y el mentol comotratamientos alternativos contra el a ́caro varroa para ́sito de la abeja de la miel. El objeto de este estudio fue observary examinar su impacto en las proteı ́nas de estre ́ste ́rmico (PET 70) en los tejidos cerebrales de las abejas. Con estepropo ́sito, se establecieron siete grupos con diferentes tratamientos usando varias concentraciones y administracionesde las mezclas de a ́cido fo ́rmico con a ́cido oxa ́lico y de timol-mentol, incluyendo controles positivo (sin tratar) y nega-tivo. Los resultados mostraron que en los grupos expuestos a tratamientos de varroa, los niveles de PET 70 fueronma ́s bajos que para los grupos sin tratar. Los resultados de PET 70 fueron ma ́s bajos en el grupo expuesto a la mezclatimol-mentol entre los grupos tratados. Concluimos que serı ́ama ́s beneficioso preferir las medicinas naturales contrala varroa, que llevan a unos resultados ma ́s bajos en las PET 70, que son los determinantes moleculares del estre ́s.
