In this study, we evaluated whether fecal microbiomes accurately reflect gut microbiomes in honey bee queens, offering a potential non-destructive approach for microbiome research. We successfully obtained fecal and gut samples from 21 out of 26 test queens. Bacterial communities were analyzed using 16S rRNA amplicon sequencing and qPCR. Our results indicate that queen fecal microbiomes closely resemble gut microbiomes, with no significant differences in alpha diversity and only minor differences in specific bacterial taxa. Beta diversity analyses revealed that within-pair microbiomes (i.e., gut vs. feces from the same queen) were significantly more similar than between-pair comparisons. Additionally, qPCR analyses revealed a strong positive correlation between bacterial abundances in fecal and gut samples, further supporting the use of feces as a proxy for gut microbiome composition. While promising, fecal collection from queens can sometimes be challenging. In our study, we were unable to collect feces from five queens, and those individuals lacked stored fecal material upon inspection of dissected guts. Nonetheless, our findings suggest that fecal sampling can be a useful, non-invasive method for studying honey bee queen microbiomes, enabling longitudinal assessments without compromising colony stability.\u0000","PeriodicalId":8078,"journal":{"name":"Apidologie","volume":"56 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13592-025-01212-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144990616","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}

These bees exhibit a unique life cycle where an individual either completes development to adulthood in summer without a diapause period or enters diapause as a prepupa, which is the overwintering life stage. Although various external factors are shown to influence diapause outcomes, the underlying mechanisms that determine these two developmental pathways are unclear. To better study when and how diapause outcomes are determined in immature bees, we investigated the likelihood that siblings occupying adjacent cells in their nest would experience the same diapause fate. We collected nests from commercial bee aggregations in alfalfa fields. The first two cells were excised from hundreds of nests collected on the same day, and only cells containing eggs or first instars were retained and then monitored over time. We recorded whether an offspring developed directly to the adult stage or remained in the prepupal stage through the fall for overwintering. Our findings revealed that across the nesting season, 91% of cell-adjacent siblings had the same diapause fate. However, time of year was a factor in how likely these siblings were to have the same fate. Near the summer solstice, only 76% of adjacent siblings had a matched diapause fate, whereas several weeks before or after this period, siblings’ fates were nearly 100% matched. Additionally, egg to prepupa development for non-diapausing offspring was about five days faster than for diapausing offspring.\u0000</div>","PeriodicalId":8078,"journal":{"name":"Apidologie","volume":"56 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144934662","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}

In order to solve the key technical bottlenecks in artificial insemination of bumblebee, we explored thoroughly the characteristics of reproductive systems of Bombus lantschouensis and B. terrestris queens. We demonstrated that the insertion depth of the needle’s tip and the volumes of semen-diluent mixture were the key factors affecting the success rate of bumblebee artificial insemination; therefore, we established the reasonable technical parameters and optimized operation flow, which have been successfully used in artificially inseminated queens of B. terrestris, B. lantschouensis, B. ignitus, B. eximius, B. melanopygus, B. patagiatus, B. breviceps, and B. montivagus. The survival rate of queens inseminated exceeded 95%, and 80% of the inseminated queens successfully founded colonies. Additionally, a rapid and direct method to evaluate the success of artificial insemination was proposed by observing the color changes of the queen’s spermatheca in vitro.

In this study, we focused on Xylocopa frontalis, a facultative solitary bee that is an important pollinator of crops, especially yellow passion fruit (Passiflora edulis f. flavicarpa), which is economically significant in several regions of Brazil. We investigated the levels of essential elements and heavy metals in the larval food of X. frontalis nests from three fragments of native Brazilian savanna and three passion fruit crops.

These results highlight the potential risk posed by environmental contamination even in areas considered relatively undisturbed and underscore the importance of monitoring multiple potentially toxic elements in wild bees to support the conservation of pollinator diversity and the continuity of their ecosystem services.

This study investigated the effects of a sublethal concentration of thiamethoxam on the Malpighian tubules (key organs responsible for excretion and detoxification) in Melipona scutellaris.

Results showed an increase in HSP70 expression on day 1 of exposure, followed by a decrease on day 8, while HSP90 exhibited the opposite trend. The observed pattern for HSP70 suggests that the Malpighian tubules initially responded to oxidative stress caused by acute exposure (1 day), while after 8 days, other metabolic responses or pathways may have been activated to counteract cellular stress. In contrast, the pattern for HSP90, which was opposite to that of HSP70, may indicate a compensatory response, with increased HSP90 levels potentially protecting the Malpighian tubules as HSP70 levels declined.

We evaluated hygienic behaviour and colony AFB resistance in 15 full-sized A. m. capensis colonies. Eight colonies originated from a population previously exposed to AFB and seven colonies were from an AFB-unexposed population. Firstly, hygienic behaviour of all colonies was assessed by the freeze-killed brood assay. Twenty percent of all colonies removed more than 95% of frozen brood in 24 h, while a further 26.67% removed more than 95% of dead brood in 48 h.

Secondly, we infected the same A. m. capensis colonies with the ERIC I subtype Ab field strain of P. larvae with a dose of 90 CFU/larva. We monitored colonies for 6 months, quantifying brood production, brood patchiness, and the number of brood cells infected with AFB. The P. larvae field strain had high virulence for all colonies regardless of previous AFB exposure or level of hygienic behaviour. The disease progressed slower in the AFB-unexposed population than in the AFB-exposed population.
