Heterotrigona itama is a stingless bee species from Meliponini tribe. The bee collects nectar, pollen and resin to produce honey, bee bread, and propolis. The bee is also known to visit and collect nectar from various types of flowers but there are limited studies on why this species of bee prefers to visit certain types of flowers. This study was conducted to identify the nectar concentration in selected flowers favoured by H. itama and the relationship between the bee and the morphology of the flowers. Nectar was obtained from different species of flowers and the concentrations were measured using a digital refractometer. The tube length of each flower species and the tongue length of the bees were also measured. The results revealed that flowers preferred by H. itama have high nectar concentrations. The tube lengths of the preferred flowers were between 2.0 and 4.0 mm, which is compatible with the tongue length of the bee. This study revealed that both nectar concentration and flower morphology are important factors for the bees in choosing their food sources. The results from this study will benefit the beekeepers in the identification of flowers that should be planted in their farms to improve stingless bee beekeeping activities. Understanding the relationship between the bees and their flower preferences could also help us to understand the importance of conserving both the bee colonies and the various species of flowering plants to ensure the sustainability of flora and fauna in the ecosystem.

Stingless bees tongue morphology is different compared to honeybees

Stingless bee species including Geniotrigona thoracica, Heterotrigona itama, and Tetragonula laeviceps are cultivated domestically in Malaysia to produce honey and bee bread and to encourage plant pollination. Bees use their mouthparts to extract nectar from diverse flowers. Different bee species are attracted to the nectar of these flowers, which is produced in varying concentrations. Understanding the morphology of the mouthparts in various stingless bee species is crucial for comprehending their robust foraging behaviour, a subject currently little explored. This study aimed to examine the detailed structure of G. thoracica, H. itama, and T. laeviceps mouthparts, with a focus on the tongue (glossa) structure. Our findings revealed that each of these three stingless bee species possesses a distinct flabellum geometry. Furthermore, we demonstrated that, in contrast to honey bees, each sensilla on the stingless bees’ flabellum is composed of a single sensilla strand. Owing to this distinction, we discuss the potential difference in nectar extraction efficiency between honeybees and stingless bees. A comprehensive understanding of bees’ mouthparts contributes to the conservation of plants and bees by optimising pollination efficiency, supporting plant reproduction, encouraging habitat conservation, and guiding native plant restoration efforts. By protecting these crucial interactions, we can safeguard ecosystems and ensure the continued survival of these invaluable pollinators and the plants they rely on.
