“…However, we cannot be certain that the temperatures at which we subjected F. varia individuals were indeed stressful for this stingless bee species. Although some studies indicated that this species had a thermal tolerance of up to 32.5°C (Sbordini 2015), it was observed that the tested individuals responded similarly to those subjected to milder temperatures. Moreover, hives of this species have been discovered in extremely hot environments, such as energy boxes (personal observation), without any harm to the colony.…”

“…To limit the likelihood of temperature changes in uencing the phototactic orientation of the bees, we established the maximum daytime temperature for conducting experiments with each species based on the thermal tolerance of each species, as described in the literature. The maximum thermal tolerances were as follows: 08:30 am for M. quadrifasciata, approximately 30°C (Silva 2019); 08:40 am for F. varia, up to 32.5°C (Sbordini 2015); and 09:30 am for S. cf. postica, approximately 40°C maximum (Macieira and Proni 2004).…”

We evaluated how ultraviolet (UV) and green light in the solar spectrum, as well as temperature, affected the proportion and latency of phototactic choice for three distinct stingless bee species within a Y-shaped maze. We showed that all studied bee species chose the edges with a higher incidence of solar UV light more often and with shorter choice latencies than other edges. Under conditions of low UV at both ends of the maze, neither a higher proportion of green nor a higher total light intensity impacted the phototactic orientation of bees towards a particular maze arm. The proportion of choice in Frieseomelitta varia did not change in response to an increase in temperature, and remained high with increased UV light. These results indicate that UV light was an important component of the phototactic response of the tropical bee species studied, and this should be considered when using them to provide pollination services in environments with a low incidence of UV light, as is prevalent in greenhouses. Moreover, the phototactic behaviour observed in F. varia, even under heat stress conditions, suggested that this species was suitable for use as pollinators in greenhouses.
