Resumen
When developing new products to be used in honeybee colonies, further than acute toxicity,it is imperative to perform an assessment of risks, including various sublethal effects. Thelong-term sublethal effects of xenobiotics on honeybees, more specifically of acaricidesused in honeybee hives, have been scarcely studied, particularly so in the case of essentialoils and their components. In this work, chronic effects of the ingestion of Eupatorium buniifolium(Asteraceae) essential oil were studied on nurse honeybees using laboratory assays.Survival, food consumption, and the effect on the composition of cuticular hydrocarbons(CHC) were assessed. CHC were chosen due to their key role as pheromones involved inhoneybee social recognition. While food consumption and survival were not affected by theconsumption of the essential oil, CHC amounts and profiles showed dose-dependentchanges. All groups of CHC (linear and branched alkanes, alkenes and alkadienes) werealtered when honeybees were fed with the highest essential oil dose tested (6000 ppm).The compounds that significantly varied include n-docosane, n-tricosane, n-tetracosane, ntriacontane,n-tritriacontane, 9-tricosene, 7-pentacosene, 9-pentacosene, 9-heptacosene,tritriacontene, pentacosadiene, hentriacontadiene, tritriacontadiene and all methyl alkanes.All of them but pentacosadiene were up-regulated. On the other hand, CHC profiles weresimilar in healthy and Nosema-infected honeybees when diets included the essential oil at300 and 3000 ppm. Our results show that the ingestion of an essential oil can impact CHCand that the effect is dose-dependent. Changes in CHC could affect the signaling processmediated by these pheromonal compounds. To our knowledge this is the first report ofchanges in honeybee cuticular hydrocarbons as a result of essential oil ingestion.
