Scientific note on side effectsof oxalic acid on the worker bee (Apis mellifera): Biochemical aspect) [Note scientifique sur les effets secondaires de l'acide oxalique sur l'abeille ouvrière (Apis mellifera ) : Aspect biochimique]

Oxalic acid is considered as widely used method for treatment against varroa destructor mite,this mite causes a considerabledisorder to honeybees comparing with other bee diseases. where as the usage of oxalic acid may causes a weakening of bee coloniesas a side effect. this study aims to determine the effects of oxalic acid on thebiochemical aspect of the honeybee apis mellifera,bystudying the variations in the content of differentmetabolites of the body and hemolymph (proteins,lipids and carbohydrates). treatment with oxalic acid disrupts the metabolism of the bee,the results show that it causes a drop in carbohydrate and fat and increased protein levels in the body and the hemolymph. these findings may explain cases of weakness reported by beekeepers afterapplication of this treatment.
