Stingless bees (Apidae: Meliponini) are eusocial bees that provide pollination services in natural and agricultural systems across the global tropics and subtropics, yet their reproductive microbiome remains poorly characterized. Here, we investigated the bacterial microbiota present in the ovaries and testes of two Australian stingless bee species, <i>Tetragonula carbonaria</i> and <i>Tetragonula hockingsi</i>, using 16S sequencing. Acetic acid bacteria (Acetobacteraceae) dominated the microbiota of ovaries and testes, primarily represented by several <i>Bombella</i>-like strains at the genus level. Phylogenetic analysis of these <i>Bombella</i>-like bacteria places them with those identified from the guts of other stingless bee species, suggesting that this group may have co-evolved with Meliponine hosts. Notably, we found no evidence in <i>Tetragonula</i> reproductives of <i>Wolbachia</i> or other parasitic reproductive endosymbionts known to be capable of manipulating insect reproduction. To further investigate the incidence of such endosymbionts within stingless bees, we conducted a large in silico search of genomic sequencing data from 18 species of stingless bees (almost all workers). This also returned no evidence of known insect reproductive endosymbionts. In contrast to solitary bees, therefore, our findings suggest that parasitic reproductive endosymbionts are particularly uncommon in the stingless bees.</p></div>","PeriodicalId":8078,"journal":{"name":"Apidologie","volume":"56 6","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145561046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For these purposes, honey bees can collect water from a wide range of sources, raising concerns among beekeepers about the risks this may pose to colony health if these waters are polluted or contaminated. However, honey bee preferences for different water sources are poorly understood, except that bees prefer to collect mineral-rich water to achieve colony nutritional homeostasis. Therefore, we investigated honey bee water preferences and how ambient temperatures, which influence thermoregulation, affect these preferences. To this end, we tested, under semi-field conditions and multiple-choice conditions, waters sampled from different environmental sources (rainwater, swimming pool water, pond water and farm puddle water) likely to be collected by bees, and slurry waters (mixture of livestock feces and urine), a reported but controversial source of water and nutrients, diluted at different rates. Unexpectedly, our results showed that honey bees expressed a strong preference for distilled water and the least mineralized waters (i.e., rainwater and 0.1% dilution of slurry water). Visits to the waterers decreased with increasing mineralization of environmental waters or with increasing concentration of slurry waters. Finally, we found that, as expected, the number of bees foraging at the waterers increased with temperature, but the bees’ water preferences remained unchanged. Our study provides a better understanding of honey bee water collection as a function of temperature and sheds light on the influence of water quality on bee’s water preferences.\u0000</p></div>","PeriodicalId":8078,"journal":{"name":"Apidologie","volume":"56 6","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13592-025-01219-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145511004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
