However, little is known about the toxic effects of chordotonal-organ-targeting insecticides (COTI) on stingless bees. Here, we evaluated the toxicity of commercial formulations of two COTIs, flonicamid and pymetrozine, on stingless bees <i>Melipona beecheii</i> and <i>Nannotrigona perilampoides</i>. After acute oral and contact exposure to field-recommended concentrations (flonicamid: 250 mg a.i./L and pymetrozine: 500 mg a.i./L), survival rates, walking speed, and flight take-off activity were assessed. Overall, the toxic effects of the insecticides were more pronounced in <i>M. beecheii</i> and when bees ingested the insecticides. Survival rates dropped to 23–32% in <i>M. beecheii</i> and 77–94% in <i>N. perilampoides</i> when exposed to the insecticides. In <i>M. beecheii</i>, oral exposure to insecticides decreased walking speed to 0.14–0.95 cm/s, compared to 3.30–3.74 cm/s for the control group. For contact exposure, only pymetrozine caused a significant reduction in walking speed (0.48–1.21 cm/s) compared to the control group (1.85–2.61 cm/s). In <i>N. perilampoides</i>, both oral and contact exposure to insecticides reduced walking speed to 0.43–0.49 cm/s, compared to 1.07–1.18 cm/s for the control group. The insecticides also significantly reduced flight take-off activity, with only 6.7% of <i>M. beecheii</i> adults and none of the <i>N. perilampoides</i> adults being able to fly after oral or contact exposure, compared to 70 and 80% of the bees in their respective control groups.

Floral diversity, abundance, and nutritional content significantly impact honey bee health. This study investigates how the diversity and structure of flowering plant communities, including landscape fragmentation, influence the nutritional availability reflected in the stored pollen within hives and its implications for the health of honey bees. Our study demonstrates that landscape diversity influences the protein-to-lipid ratio of pollen diets, specifically the protein-to-lipid ratio increases as the landscape diversity rises. This increase in protein-to-lipid ratio was also associated with the increased total bee density. Diverse pollen species in the diet enhance nutritional content, promoting healthier bees through resource complementarity. Bees exhibit adaptive foraging behavior, systematically diversifying their floral sources to optimize nutrient intake. The diversity in pollen reserves also correlates negatively with <i>Varroa destructor</i> prevalence, likely because the diversity of pollen enhances the nutrition and overall health of honey bee colonies.

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.

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 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.
