“…Although T. amalthea was registered consuming petals of sapoti flowers, other species such as T. fulvientris and T. (fieseomeitta) nigra were observed on the flower reproductive structures (Figure 3b-d). According to previous studies, some of the nearly 75 species from Trigona genus (eof, 2018) are important pollinators (KAKUTANI et al, 1993;BEZERRA et al 2020).…”

In Colombia there is a large diversity of promising fruit trees, one of them is Matisia cordata. Sapoti species is appreciated by the consumers, although it is produced in small volumes by traditional productors. The objective of this research is to describe the floral and reproductive biology of sapoti, including floral visitors that act as biotic pollination agents. The study was conducted in two farms, between February/2016 and July/2017. In the first farm, floral buds were marked to follow the stages until fruit formation, pollination mechanism was studied, and floral visitors were collected for identification. In the second farm, flowers were marked to measure the floral nectar production. The duration from floral bud to ripe fruit was 269 days, the 2.7% of the flowers reached the fruit stage. Twenty-five floral visitors were registered, seven of which contacted the sexual whorls, specially Meliponini bees, hummingbirds and bats from Artibeus and Glossophaga genus. M. cordata is a prevalently allogamous species, it attracts diurnal and nocturnal animals, which can contribute to the pollination process. The flowers produced 1.6 ml of nectar with a sugar content from 6.2 to 11 °Brix. The sapoti flowers constitute an abundant and valuable resource for animals from the region.

“…The two species of bees showed the different preference among plant species. In açaí palm (Euterpe oleracea), two species stingless bees (Trigona branneri and T. pallens) collected 128.8 and 58.4 pollen grains (median pollen load), respectively (Bezerra et al, 2020). Stingless bees are generalist visitor and play important role in plant pollination, therefore conservation and management of pollinators are needed.…”

Stingless bees (Apidae: Meliponinae) are eusocial insects that distributed in the tropics and subtropics. Stingless bees are pollinators for various plant species. Foraging activities of worker stingless bees collect pollens, nectar, resin or water as nutrients for individuals and colony needed. This study aimed to measures pollen load and pollen composition carried by four species of stingless bees, i.e., Tetragonula laeviceps, Lepidotrigona terminata, Heterotrigona itama, and Geniotrigona thoracica in urban area at Bogor, Indonesia. Acetolysis method was used for pollens preparation and pollens were counted by using hemacytometer under light microscope embedded with camera. The study showed that the highest pollen load occurred in H. itama (59181 pollen grains), followed by L. terminata (27806 pollen grains), T. laeviceps (20816 pollen grains), and G. thoracica (11775 pollen grains). The number of pollens collected by T. laeviceps, L. terminata, and H. itama positively correlated with body size. Thirteen types of pollen were identified on the body of stingless bees. Pollen composition collected by T. laeviceps were dominated by Chlorantaceae (50%) and Polygonaceae (20%), L. terminata and H. itama were dominated by Asteraceae (70.19% and 62.76%) and Arecaceae (22.87% and 29.65%), while in G. thoracica was dominated by Apocynaceae (53.53%) and Acanthaceae (34.32%). Lepidotrigona terminata and H. itama carried of small pollen-size and G. thoracica carried moderate pollen-size.

“…The cultivated area of several cash crops with high market value and great dependence on pollinators has increased from one-to three-fold in LA during the last five decades (FAOSTAT 2017). For example, the Brazil nut (Bertholletia excelsa) and the açaí palm (Euterpe oleracea) are cultivated in the Amazon region, and crop production is dependent on native bees as pollinators (Campbell et al 2018;Cavalcante et al 2018;Bezerra et al 2020) (Figure 1 h). Some species of passionflower, such as passion fruit (Passiflora edulis f. flavicarpa), are clear examples of the dependence of an industrial crop on the presence of wild bees to increase productivity (Camilo 2003;Calle et al 2010;Yamamoto et al 2012).…”
