This bacterium plays a crucial role in the life of \u003cjats:italic\u003eB. oleae \u003c/jats:italic\u003eand is necessary for its fitness. Thus, in the absence of the endosymbiont, \u003cjats:italic\u003eB. oleae\u003c/jats:italic\u003e wild populations in the field might decrease considerably. Copper is one of the most used antimicrobials for horticultural crops worldwide, and its efficacy against \u003cjats:italic\u003eCa\u003c/jats:italic\u003e. E. dacicola has been demonstrated in field trials. Propolis is another natural antimicrobial compound largely used for its activity in several fields. If propolis and copper prove to be efficient against wild populations of the endosymbiont \u003cjats:italic\u003eB. oleae\u003c/jats:italic\u003e in the field, such a biological restraint might improve sustainable agriculture. We evaluated, under laboratory conditions, the effect of two different copper products (at two different concentrations, 5% and 20%) and propolis on the content of \u003cjats:italic\u003eCa\u003c/jats:italic\u003e. E. dacicola in the eggs and in the adult oesophageal bulbs of \u003cjats:italic\u003eB. oleae\u003c/jats:italic\u003e. Bulbs were extracted twice, after 2 and 5 weeks of exposure. Real‐time PCR on the bulbs showed a reduction in \u003cjats:italic\u003eCa\u003c/jats:italic\u003e. E. dacicola content in flies treated with copper (at both 5% and 20%), and from the first to the second extraction, while flies treated with propolis showed an increment of the relative abundance of \u003cjats:italic\u003eCa\u003c/jats:italic\u003e. E. dacicola. Both copper products (5% and 20%) reduced the egg production after 2 and 5 weeks in comparison with the control and propolis treatments. Moreover, adult mortality was significantly higher with propolis compared with the other treatments. Thus, our results encourage further research in order to develop new tools for the control of the olive fly in the framework of an integrated pest management strategy.\u003c/jats:p\u003e","long_citation_html":"Bigiotti et al.
