Researchers have used two manual dance decoding methods to infer the spatial foraging patterns of the bees. The ‘waggle run method’ infers foraging distance from waggle duration, representing the actual distance signal of the bees, and the ‘circuit method’ infers foraging distance from the duration of complete dance circuits, including both waggle and return phases. The circuit method enables decoding dances by real-time observation and is likely quicker, but it might give inaccurate distance estimates due to variations in the return phases. Here, we decoded 200 natural waggle dances from four <i>Apis mellifera</i> colonies using both methods to test how well inferences about foraging locations would match and compared the time required for dance decoding. We found a high linear correlation between foraging distances inferred from waggle duration and circuit duration (<i>R</i><sup>2</sup>, 0.793). However, the circuit method systematically overestimated foraging distances by about 86 m. Both methods provided similar results with respect to relative differences in spatial foraging patterns between the four test colonies. Decoding the dances using the circuit method was three to four times faster than the waggle run method (2 versus 7.3 min per dance). We conclude that the circuit method can be used for many research questions that require manual dance decoding to minimize time costs. However, when aiming to maximize the accuracy of inferred foraging locations, systematic errors of the circuit method should be accounted for, or the waggle run method should be used.</p></div>","PeriodicalId":8078,"journal":{"name":"Apidologie","volume":"56 2","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13592-025-01164-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740810","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}

Differentially expressed genes were categorized based on gene ontology, revealing alterations in critical biological processes, molecular functions, and cellular components.

Bumblebee spillover to natural habitats near the orchards may interfere with local wild bees and impact the pollination of non-crop plants. Concurrently, foraging in natural habitats may diversify the bumblebees’ diets and improve colony development. To evaluate these potential effects, we placed commercial <i>Bombus terrestris</i> colonies in blooming Rosaceae orchards, 25–125 m away from the margins. We recorded the colonies’ mass gain, population sizes, composition of stored pollen, and temperature regulation. We monitored bee activity, and seed sets of the non-crop plant <i>Eruca sativa</i>, along transects in a semi-natural shrubland up to 100 m away from the orchards, with managed bumblebees either present or absent. Rosaceae pollen comprised ~ 1/3 of the colonies’ pollen stores at all distances from the orchard margins. Colonies placed closest to the margins showed prolonged development, produced fewer reproductive individuals, and had poorer thermoregulation than colonies closer to the orchards’ center. Possibly, abiotic stressors inhibited the bumblebees’ development near orchard borders. Wild bees were as active during the colonies’ deployment as after their removal. <i>E. sativa</i>’s seed sets decreased after bumblebee removal, but similar declines also occurred near a control orchard without managed bumblebees. Altogether, we found no short-term spillover effects of managed bumblebees on nearby plant-bee communities during the orchards’ two-week flowering. The colonies’ prompt removal after blooming can reduce longer-term ecological risks associated with managed bumblebees.</p></div>","PeriodicalId":8078,"journal":{"name":"Apidologie","volume":"56 2","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13592-025-01172-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698471","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}

Aggressive interactions were 13 times higher during the morning when bees were less active. The most frequent interaction at noon involved wasps approaching the hive, while in the morning, it was frequent to observe wasps entering the hive.

We concluded that bee activity, measured as bee traffic at the hive entrance, could be an indicator of susceptibility to wasp attacks and a key factor in this predator‒prey interaction, making hives more susceptible to <i>V. germanica</i> attacks in the morning.

Sealed worker brood cells at the development stage of white to purple-eyed pupae are swiftly decapped with wax strips to observe and count surfacing adult mites. The results from our study show supporting evidence of over 90% detection efficacy and brood survival, and ease of application.

In 2021, Abou-Shaara et al. predicted a high risk of LHB invasion into the North African and South Europe regions due to temperature variations. As a result, we performed a follow-up study based on a survey to assess the spread of LHB across the Arabian region. The questionnaire contained essential items from the global COLOSS surveys. During a two-month survey in 2024, 54 beekeepers from 11 Arabian countries responded, with Egypt, Algeria, Saudi Arabia, and Yemen contributing the most data. The infestation rate was highest in countries along the Mediterranean and the Red Sea, including Algeria, Tunisia, Egypt, Palestine, Saudi Arabia, and Yemen, indicating that LHB may favor coastal weather conditions.
