“…Recent studies suggest that bacterial symbionts may play a role in their host’s DNA methylation [ 54 , 55 , 56 ], and the shift in size observed in our study implies that B. floridanus might influence the Egfr pathway and thus development of minor workers. The smaller size of symbiont-reduced colonies, similar to in other studies [ 43 ], and corresponding reduced major-to-minor worker ratio indicates that B. floridanus may contribute to worker polymorphism directly through supporting individual body size and indirectly by promoting colony size. To disentangle the relative contributions of direct and indirect effects of defaunation on major-to-minor worker ratios in C. floridanus colonies, it would be necessary to obtain worker ratios from small colonies on ordinary diets.…”

“…The antibiotic diet consisted of a two-week diet cycle, where in the first week, ants received a diet consisting of a 1 M sucrose with 1% ( w / v ) rifampicin (Sigma-Aldrich, Saint Louis, MO, USA) solution and T. molitor larvae three days per week, and in the second week, ants received the antibiotic-devoid diet on one of the three days. A rifampicin diet was selected as it has been widely used within Camponotus species to reduce or eliminate Blochmannia [ 21 , 25 , 29 , 31 , 43 ], as indicated by FISH microscopy and qRT-PCR [ 25 , 31 ]. Thus, we considered B. floridanus to be reduced from the fourth month onward in colonies that received the antibiotic diet.…”

“…Interestingly, grain weevils that occupy an almost identical ecological niche evolved a symbiotic association with γ‐proteobacteria ( Sodalis pierantonius ) that supports cuticle biosynthesis in a similar manner (Heddi et al., ; Vigneron et al., ) and may hence contribute to drought tolerance. Likewise, carpenter ants of the genus Camponotus and the invasive ant Cardiocondyla obscurior evolved symbioses with the γ‐proteobacteria Blochmannia and Candidatus Westeberhardia cardiocondylae, respectively, that support cuticle melanization through the synthesis of essential amino acids or tyrosine precursors, respectively ( Blochmannia , De Souza, Devers, & Lenoir, ; Candidatus Westeberhardia, Klein et al., ). However, in which way these ants benefit from enhanced cuticle melanization remains unclear.…”

“…Contrarily, however, topical antibiotic administration on Acromyrmex subterraneus leafcutter ants does not affect cuticular hydrocarbon profiles (19). Similarly, a study on Camponotus carpenter ants revealed a negative correlation between the levels of the bacterial gut symbiont Blochmannia and CHC quantities, whereas relative CHC proportions were not affected (20). Finally, antibiotic administration affects interspecific but not intraspecific social interactions in the Argentine ant Linepithema humile , suggesting gut microbiota not to be involved in nestmate recognition in this ant species (21).…”

“…Despites providing insights into the role of symbiotic microbes in CHC-mediated nestmate recognition, these studies either investigate microbial effects through behavioural tests, without correlating CHC measures (17,21), or compare CHC profiles between antibiotic-treated and control individuals without behavioural tests (1820). To gain more insights into the interplay between gut microbiota and chemical-based social interactions, we here seek to implement an integrative analysis of CHC, gut bacterial communities and nestmate recognition behaviour.…”
