Contamination of the environment with metals can lead to a decline in honey bee populations. Copper (Cu) and zinc (Zn) salts are commonly used as fungicides and foliar fertilizers. In this study, we investigated the effects of 10-day chronic oral exposure to different concentrations of Cu (CuSO4) and Zn (ZnCl2) on survival and feeding rates of Carniolan honey bees in laboratory conditions. We found that mortality in honey bee workers increased in a concentration-dependent manner and that Cu (lethal concentration [LC50]\u2005=\u200566 mg\/l) was more toxic than Zn (LC50\u2005=\u2005144 mg\/l). There was no difference in the feeding rate of Cu-treated bees for the different concentrations tested, but the feeding rate decreased with the increase in Zn concentration. To determine feeding preference or avoidance for Cu and Zn, we conducted 2-choice 24-h feeding experiments. We demonstrated that honey bees preferred Zn-containing solutions compared to the control diet. A two-choice experiment with Cu showed a tendency for honey bees to be deterred by Cu at high concentrations; however, it was not statistically significant. In summary, our results suggest that honey bee workers may suffer adverse effects when exposed to ecologically relevant concentrations of Cu and Zn.<\/jats:p>","DOI":"10.1093\/jee\/toae108","type":"journal-article","created":{"date-parts":[[2024,5,15]],"date-time":"2024-05-15T16:07:17Z","timestamp":1715789237000},"page":"1485-1492","source":"Crossref","is-referenced-by-count":7,"title":["Impact of copper and zinc oral chronic exposure on Carniolan honey bee survival and feeding preference"],"prefix":"10.1093","volume":"117","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8170-8075","authenticated-orcid":false,"given":"Gordana","family":"Glavan","sequence":"first","affiliation":[{"name":"University of Ljubljana Department of Biology, Biotechnical Faculty, , Jamnikarjeva 101, SI-1000 , Ljubljana, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grega","family":"Benko","sequence":"additional","affiliation":[{"name":"University of Ljubljana Department of Biology, Biotechnical Faculty, , Jamnikarjeva 101, SI-1000 , Ljubljana, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janko","family":"Bo\u017ei\u010d","sequence":"additional","affiliation":[{"name":"University of Ljubljana Department of Biology, Biotechnical Faculty, , Jamnikarjeva 101, SI-1000 , Ljubljana, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2024,5,15]]},"reference":[{"issue":"5","key":"2024081216421467900_CIT0001","doi-asserted-by":"crossref","first-page":"562","DOI":"10.3390\/plants9050562","article-title":"Zinc Hyperaccumulation in plants: a review","volume":"9","author":"Balafrej","year":"2020","journal-title":"Plants"},{"issue":"1","key":"2024081216421467900_CIT0002","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1006\/eesa.1996.0082","article-title":"Toxicology of cupric salts on honey bees V.
