“…Many of the apricot orchards are located adjacent to natural and managed forests, which are thought to provide stable habitats for the native Apis cerana . The two Apis species are the main pollinators of the apricot, which blooms from mid or late February to early or mid-March, during which few other flower-visiting insects are available (14). All our bee and nectar collection sites were located within this landscape, but at least 1.0 km away from their respective nearest neighboring collection site in each season (Fig.…”

“…Our crop and mouth samples come from foraging adults of the introduced Apis mellifera and the native A. cerana japonica (hereafter A. cerana ) collected in the Minabe-Tanabe region of Wakayama Prefecture in Japan. In this region, farmers use both species of honeybees to pollinate the winter-blooming Japanese apricot, Prunus mume (14). Our nectar samples come from P. mume flowers near the hives of the A. mellifera and A. cerana bees that we caught for crop and mouth sampling.…”

Bacteria in the honeybee gut have garnered much attention as a factor affecting bee health. However, unlike the hindgut, which has been the primary focus of this research, the crop, or the honey stomach, is often assumed to be dominated by environmentally acquired transient taxa that matter little to the bees. To evaluate this assumption, we examined bacterial taxa in the crop and the mouth of foraging adults of Apis mellifera and A. cerana japonica and the floral nectar of the Japanese apricot, Prunus mume, visited by the bees in the Minabe-Tanabe region of Japan. We found that the crop was distinct from both the mouth and the nectar in bacterial composition even though all samples were collected simultaneously at the same locations, whereas mouth and nectar samples were indistinguishable from each other. Furthermore, the crop remained similar in bacterial composition and alpha and beta diversity from summer to winter, whereas the mouth showed a sharp drop in alpha diversity and a large increase in beta diversity from summer to winter. These results refute the conventional assumption, suggesting instead that the crop contains a conserved bacterial community that is largely distinct from the environmental taxa that the bees encounter as they forage in the environment. We also found, however, that strains of a representative crop-associated species, Apilactobacillus kunkeei, could be season- and host species-specific. Together, these findings suggest that further studies of crop-associated bacterial communities are needed to better understand the relationship between honeybees and their gut bacteria.

“…Research has shown that diel temporal partitioning of pollination can affect interactions between plants and their pollinators in many ways. During the day, abiotic conditions like temperature influence floral visitation activity by diurnal pollinators (Maeda et al, 2023; Zoller et al, 2020). In temperate and dry habitats, night temperatures can be considerably lower than day temperatures.…”

Distinct diurnal and nocturnal flower visitor communities provide pollination services in urban gardens

Urban gardens are considered a key tool for mitigating biodiversity and plant‐pollinator interaction loss due to their ubiquity in urban landscapes and the variety of resources they provide. To date, most urban garden pollination research has focused on diurnal pollination, omitting a potentially important group—nocturnal pollinators. To assess the diversity and pollination activity of both diurnal and nocturnal flower visitors in urban gardens, I monitored arthropods on focal inflorescences of Eupatorium perfoliatum, a common Michigan‐native species, for 24‐h cycles and recorded the number and duration of visits. I also measured diurnal and nocturnal communities' pollination services using a temporal floral visitation exclusion experiment. Flowers averaged nearly twice as many visits during the day as compared with night within 24‐h cycles, but nocturnal visit durations were 2.5‐fold longer on average. Day and night floral visitor communities were distinct, with day visits being dominated by Diptera, ants and other Hymenoptera, and night visits being carried out most frequently by ants, Dermaptera and Hemiptera. In the floral visitor exclusion experiment, plants open to only nocturnal visits produced larger seeds, whereas plants open to only diurnal visits trended towards producing more seeds, signalling a potential trade‐off between seed quantity and size among visitor communities. Overall, diurnal and nocturnal floral visitor communities were distinct, and nocturnally pollinated plants had reproductive output comparable to diurnally pollinated treatments. Given the emphasis on diurnal pollinators in most pollination studies, it is possible that relevant plant‐pollinator interaction information may be missed in cases where anthesis spans both day and night.
