        <description><![CDATA[IntroductionCoffee production depends heavily on pollination services, but the combined effects of managed pollinators and pesticide use on crop yield and pollinator health are still poorly understood. This study evaluated the contribution of supplemental pollination by the stingless bee Scaptotrigona depilis to coffee yield and assessed the impact of thiamethoxam, a neonicotinoid insecticide, on colony strength in Brazilian coffee farms.MethodsColonies of S. depilis were introduced into both conventional and organic coffee farms. Coffee yield was measured in branches located near and far from bee colonies. Colony strength parameters were monitored over time, and pesticide residues were quantified in plant tissues (leaves, nectar, pollen) and in bee-collected floral resources.ResultsSupplemental pollination by S. depilis significantly increased coffee yield by 67% in branches closer to the colonies. Low but detectable residues of thiamethoxam and its metabolite clothianidin were found in plant tissues and bee-collected resources. No significant negative effects were observed on brood production or brood mortality in colonies located in conventional farms compared to those in organic farms. Foraging activity differed between farm types before exposure to coffee bloom but normalized over time.DiscussionManaged stingless bees can markedly enhance coffee production without experiencing measurable detrimental effects under current label-compliant neonicotinoid use. These findings offer practical insights for developing more sustainable coffee production strategies that align productivity with pollinator health and conservation.]]></description>

        <description><![CDATA[Climate change is one of the main drivers of biological reorganization, population decline of pollinators, and disruption of species interactions. These impacts represent a major threat to crop pollination and human food security. Here, we tested the hypothesis that the spatial mismatches between Neotropical food plant species and their bee pollinators are exacerbated under scenarios of projected climate change. To investigate this hypothesis we performed species distribution modeling to simulate the effects of climate change on suitable habitats for the occurrence of both native food plants and their main pollinators. We selected three economically important food plants native to Brazil bearing a self-incompatible reproductive system that is strictly dependent on pollinators: (1) Bertholletia excelsa, (2) Eugenia uniflora, and (3) Passiflora edulis; and we selected the main effective bee pollinators of each plant species: (1) Apis mellifera (i.e., pollinator of E. uniflora), (2) Eulaema mocsaryi (i.e., pollinator of B. excelsa), and (3) Xylocopa frontalis (i.e., pollinator of P. edulis). We documented that climate change will likely distinctly affect areas of suitable habitats for food plants and their main bee pollinators across Brazil, in which all species will likely experience contractions in their ecological niches. In addition, we also documented that suitable habitats were reduced for the co-occurrence of all food plants and their pollinators. Specifically, 51.5% for P. edulis and X. frontalis, 76% for B. excelsa and E. mocsaryi, and 54% for E. uniflora and A. mellifera. Therefore, these findings underscore that plausible climate change scenarios can act as a potential driver of spatial mismatches between food plants and their main pollinators, disrupting the pollination of these food plants. Our results show that plant and pollinator species respond negatively to the impacts of climate change under all scenarios, which can result in alarming projections for strictly bee-pollinated self-incompatible plant species. This study reaffirms that bees are sensitive to climate change, highlighting the negative impact even for the exotic European honeybee, Apis mellifera. Finally, climate change could impact crop pollination, with detrimental implications for food production and food security.]]></description>

        <description><![CDATA[IntroductionIn Australia, as well as many other regions of the world, European honey bees Apis mellifera are an introduced species and may harm native bee fauna by competing with them for food resources. Field studies have revealed negative associations between honey bee and native bee abundance, but whether this translates to fitness costs for native bees is unclear.MethodsUsing drilled wooden-block trap nests, we evaluated whether honey bee abundance is associated with fitness parameters (number of nests, provisioned cells per nest, offspring number, mortality rate, sex ratio, and body size) of cavity-nesting native bees over 2 years. We also conducted palynological analyses to measure pollen resource overlap and evaluate whether this impacts native bee fitness.Results and discussionGreater honey bee abundance was associated with a male-biased sex ratio in the native bee progeny across years and an increased mortality rate of native bee progeny in the first year. Most non-significant associations were also in the directions predicted from honey bees adversely impacting native bee fitness. In the first year, greater pollen morphospecies overlap was associated with fewer provisioned cells. In conclusion, we demonstrated that honey bees have the potential to have harmful consequences for native bee fitness.]]></description>

        <description><![CDATA[Anthropogenic disturbances mainly involve the loss of habitats in tropical regions where there is also significant population growth. These disturbances also have an impact on the plant pollination service, which is struggling to be explored in the Lubumbashi region, where mining interests seem to take priority given the local connotations and the predominance of players within the sector. The present study focuses on an analysis of the pollination service and the interactions maintained between bees and their host plants, in a context of agricultural impetus through the practice of agroforestry, the benefits of which supposedly extend from improved yields to efforts to conserve global biodiversity. Subject to the sampling effort at the limits of the favorable periods, our results indicate a significant biodiversity of bees, unevenly distributed among the families Apidae, Halictidae and Megachilidae. The species Xylocopa albiceps, Nomia speciosana, X. olivaceae and Megachile torrida dominate the abundance ranks, while more restricted than general interactions between pollinators and their host plants are recorded.]]></description>

        <description><![CDATA[Land use, local management, and seasonal variation significantly impact the ecological dynamics of bee–plant communities and their ecological interactions. These variables negatively affect diversity and ecological interaction networks within human-dominated landscapes. Additionally, seasonal variables such as temperature, rainfall, and resource availability across different seasons play essential roles in shaping bee communities and their interactions with flowering plants. However, little is known about how diversity and ecological interaction networks of non-crop plants in agricultural landscapes respond to intra-seasonal variations, specifically within the rainy season. In this study, we assessed how land use types, coffee crop management, and intra-seasonal variation within the rainy season influenced the composition and diversity of bee and plant communities, and their interaction networks in semi-natural habitats surrounding coffee plantations. We recorded the diversity of bees and plants and analysed their interactions networks metrics, such as specialisation, nestedness, modularity, connectance and bee/plant generality, in 8 pairs of sites. Our findings indicate that human settlements negatively influence bee generality, suggesting that human-dominated land and the introduction of exotic plants reduce floral resources for bees, which may decrease bee visitation. In contrast, extensive semi-natural and forested areas seemed to support bee generality. Additionally, we observed higher visit frequency and richness of bees and plant generality during the second period of the rainy season (July to October), leading to more robust bee–plant interaction networks in the same period. This study enhances our understanding of how land-use types and intra-seasonal climatic variation shape structure of bee floral visitor communities and their interactions with flowering plants. Furthermore, our findings underline the negative impact of human-dominated landscapes on the ecological dynamics of plants visited by bees and their interaction networks.]]></description>

        <description><![CDATA[Sustaining honeybee colonies is challenging during dearth periods as their metabolic functions are reduced due to limited foraging activities. The experiment used honeybee colonies of Apis mellifera, and five different low-cost supplementary foods—sugar, banana, pumpkin, maize flour, and rice flour syrups—were introduced as treatments. Every box for each treatment received a daily 300-ml supplementary food syrup consisting of a specific amount of feeding materials along with 100 g of brown sugar and 20 g of honey. The amount of food consumed was assessed on the second day following the supplementation. Supplemental food with low-cost feeding materials significantly impacts the growth and strength of the colonies. Results revealed significant impacts on colony growth and strength, with all supplements contributing to food consumption over 78%. Despite variations in brood and pollen cells, all feeding supplements showcased efficiency in supporting honeybee feeding, indicating their potential utility in mitigating the challenges during the dearth period. Notably, pumpkin syrup emerged as the best supplement, offering cost-effectiveness compared to sugar and banana syrups, and it could reduce sugar syrup costs by 50% while enhancing brood, honey, and pollen cell production by 71.36%, 108.36%, and 58.73%, respectively. The findings of the economic analysis revealed that the cost of feeding materials was the highest for sugar syrup ($1.89), followed by banana ($0.91), pumpkin ($0.83), maize ($0.53), and rice ($0.53). This study suggests that supplementing honeybee colonies with low-cost feeding materials can positively impact colony growth and strength during dearth periods and advance the beekeeper’s decision as a cost-effective alternative to traditional sugar syrup.]]></description>

        <description><![CDATA[Cocoa (Theobroma cacao) is a multi-billion-dollar business. This tropical crop strongly depends on animal pollination for fruit development and seed production. The lack or inefficiency of natural pollinators in cocoa plantations has driven farmers to search for alternatives, such as laborious pollination by hand. A so far untested alternative, which has received increasing attention during the past couple of years, is targeted crop pollination through managed social bees. However, owing to the smallness of the flowers of T. cacao as well as structural barriers that impede large insects to access the stigma, only tiny bees may be a viable option for targeted cocoa pollination. In the present study, we asked whether small stingless bees (Apidae, Meliponini) could come into consideration as managed cocoa crop-pollinators, especially in shadowy agroforests. Among the 188 meliponine species native to the Brazilian Amazon region, which comprises an important portion of the center of origin of T. cacao, we selected 52 species based on morphological criteria (intertegular distance ≤ 1.4 mm; body length: 2.2–6.0 mm). Important for cocoa production, some of these Meliponini have an ample geographic distribution, occurring both in the center of origin of T. cacao and beyond (centers of cocoa production in Brazil: Pará: 35 spp., Bahia: 10 spp.). Presumably all species may be active at illuminance levels below those found in heavily shaded cocoa plantations, at least at times when anthers show full dehiscence and during maximum receptivity of the stigma. The bees’ potential to forage under reduced light regimes is corroborated by the finding that between 20 and 60% of the naturally exploited food sources are understory vegetation, including herbs, subshrubs, shrubs, and lianas. Many of the selected Meliponini build their nests, at least facultatively, in tree cavities, which facilitates their transfer to rational hives and, hence, the use of managed colonies in directed crop pollination. Important next steps for validating the potential of these small stingless bees in targeted cocoa pollination should comprise detailed studies on their foraging behavior and olfactory learning capacities.]]></description>

        <description><![CDATA[IntroductionHabitat loss and fragmentation have negative impacts on pollinator populations and thus on the pollination services they provide. Negative effects can be lessened by the presence of forest remnants that serve as refuges and sources of food for pollinators. However, few studies have analyzed the influence of highly heterogeneous agricultural landscapes (as commonly found in many developing countries), on pollination services.MethodsWe compared native bee diversity, pollination visitation, and fruit set of Brassica rapa L. between two land use conditions (sites maintaining more than 15% of the original forest coverture [Moderately Modified], and sites with less of 10% [Highly Modified]) in the highlands of Guatemala.ResultsNative bee diversity was higher in HM areas, although social bees were more abundant in MM sites. We did not find differences in pollinator visitation rate between conditions. HM sites were mainly visited by honeybees (Apis mellifera Linnaeus), while native bees and syrphid flies were more frequent in the MM condition. Fruit set was significantly higher in MM sites and was positively affected by natural forest areas. Experiments on pollen limitation and on pollinator efficiency stressed the importance of native pollinators in fruit production, especially in moderately modified areas.DiscussionOur results highlight the role of forest remnants for the provision of pollination services in tropical agricultural highlands and underline the relevance of appropriate management of introduced bees such as A. mellifera.]]></description>

        <description><![CDATA[Along with higher average temperatures, global climate change is expected to lead to more frequent and intense extreme heat events, and these different types of warming are likely to differ in their effects on bees. Although solitary bees comprise >75% of bee species, and despite their ecological and economic value as pollinators, a literature search revealed that only 8% of studies on bee responses to warming involve solitary bees. Here we review studies that have addressed how solitary bees are affected by three main types of warming that vary in magnitude and duration: heat shocks, heat waves, and sustained warming. We focus on direct physiological and behavioral effects of warming on solitary bees, rather than the underlying mechanisms. We find that heat shocks have received little attention in solitary bees both in terms of number of studies and relative to social bees, and all of those studies examine the effects of heat shocks on a single genus, Megachile. This work has shown that heat-shocked eggs, larvae, and pupae tend to upregulate heat shock protein genes, while heat shock at the adult stage can increase mortality in male bees, potentially altering population sex ratios. We find that solitary bee responses to heat waves have received even less study, but the few studies suggest that these events can increase larval mortality and slow development time, and that bees may not be able to physiologically acclimate to heat wave conditions by increasing their critical thermal maxima. Finally, sustained warming, which has been relatively well-studied in solitary bees, can speed development rate, reduce body mass, increase mortality, and alter foraging behavior. Our review reveals knowledge gaps in the effects of heat shocks and heat waves on solitary bees and, more broadly, in the responses of unmanaged solitary bees to warming. To improve our ability to anticipate the consequences of climate change for these critical pollinators, we encourage research on solitary bee thermal responses that examines short-term, extreme warming and incorporates greater ecological realism and complexity.]]></description>

        <description><![CDATA[Insect conservation through habitat management is particularly important in regions of high biodiversity potential, such as steep-slope viticultural landscapes. Therefore, we studied the effects of realistic options for the conservation of open and flower-rich vineyard fallows on local wild bee communities. Using a fully-crossed factorial design, we sampled bees in 10 vineyard fallows in the Moselle region (SW Germany), which were partially subjected to different treatments (mulching, sowing of wild flower strips, combination, and untreated control). Over two years, we sampled 9323 individuals from 140 bee species with hand netting and pan traps. Based on the hand-netting samples, AICc-based model selection (Generalized Linear Mixed Models) revealed effects of fallow treatment, interacting with sampling year, on the number of sampled bee individuals and on the number of sampled bee species. In the second sampling year, we sampled significantly more individuals in wild flower strips (WFS) as well as in the combination treatment than in the untreated control. Also in the second year, the number of sampled species was significantly higher in the combination treatment than in the mulching treatment, and significantly higher than in the untreated control. Vineyard fallow management can promote bee communities in steep-slope viticultural landscapes, and options involving WFS, especially in combination with an annual mulching, should be preferred over options solely relying on repeated mulching. Moreover, the findings highlight that management options involving WFS need some time after initiation for unfolding their positive effects on bee communities.]]></description>

        <description><![CDATA[Plant-pollinator interactions constitute complex mutualistic relationships responsible for the maintenance of the reproduction of flowering plants in different biomes. The genus Centris stands out as one of the main groups of pollinators in the Neotropical region. These bees have a close relationship with floral oil-producing plants, using this resource in the construction of their nests and/or larval feeding. The aim of the present study was to compare the resources exploited by Centris perforator and Centris xanthomelaena and assess the established trophic relationships of these two species in a fragment of dry forest (Caatinga domain). For such, direct observations were made at the flowers and analyses were performed of the pollen load on the body of female bees and the content of the larval provisions in the nests. A strong association was found between the two bee species and plants with poricidal anthers of the genus Chamaecrista, which accounted for more than half of the larval diet in both species. Samples of the pollen load of C. xanthomelaena exhibited a greater diversity of pollen types. While Rhaphiodon echinus was a constant source of nectar for C. xanthomelaena, C. perforator females collected nectar from plants of short, rapid flowering, such as Cenostigma microphyllum and Tabebuia aurea. Malpighia emarginata was the main source of floral oil for both species. However, C. xanthomelaena also interacted with Angelonia cornigera and Krameria sp. to obtain this resource. The similarity in the trophic niche of the species was 57% in the subsamples of pollen on the body of females and 46% for larval provision. The results showed that areas of native vegetation are essential for bee populations in regions with agricultural activity, ensuring a regular supply of ecological resources for these bees.]]></description>

        <description><![CDATA[Our project assessed whether adding floral scents to pan traps would increase the abundance and/or diversity of Hymenoptera sampled or decrease bycatch. We sampled insects using white pan traps containing 0.5 mL of floral scent (linalool, phenylacetaldehyde, limonene, geraniol, benzaldehyde, no scent control) per liter of trapping solution in an interior southern California natural space. Scented traps shared between 53.0% and 79.7% similarity in Hymenoptera assemblage and 59.5% and 72.2% similarity when using presence/absence data as compared with the control. Phenylacetaldehyde and geraniol increased the capture rate of new Hymenoptera, while phenylacetaldehyde also increased overall Hymenoptera and bycatch capture rate. Additionally, we noted that phenylacetaldehyde traps increased small parasitoid wasp capture 10-fold, potentially indicating an alternative use for the addition of phenylacetaldehyde to pan traps. We found no evidence that the addition of scent decreased the abundance or diversity of Hymenoptera caught. Those seeking to exhaustively record the species richness in an area may benefit the most from this method with potential to increase capture of large-bodied, rare, or specialist pollinating Hymenoptera with scent preference, though further research is needed. Based on the data presented here, scent should be explored further for its effect on pan trap catch.]]></description>

        <description><![CDATA[As pollinator-dependent crops continue to expand globally, management strategies are needed to meet the current demand for pollination services. Improving the efficiency of pollinators depends on knowledge about crop plant biology as well as pollinator behavior. In this sense, we will review the scope and challenges of implementing a targeted pollination strategy based on the behavioral individual and social plasticity of the honey bee Apis mellifera. Here we summarize current knowledge on the bees´ ability to perceive, learn and generalize floral odors, the bias of their foraging preferences after in-hive experiences and the transfer of food source information within the social context of the colony, all aspects that impact on foraging decisions and can be used to direct pollinators to target crops. We focused on describing how key olfactory cues that mimic crop floral scents are acquired in the hive and propagate among colony mates to guide foraging to specific crops. Knowledge gaps, including volatiles variability between flowers of the same or different crop varieties, alternative managed pollinators, and potential impact on food industry are discussed.]]></description>
