“…This could reveal an increased protection against oxidative stress since increased enzymatic rates in insects can lead to higher metabolic rates 56 . In addition, this hypothesis is consistent with our previous results 42 , showing a vitellogenin increase in bees whatever their task specialization (nurse, guard and forager) in response to a heat stress in laboratory conditions.…”

“…Cycle threshold values of vitellogenin, apidaecin 1, defensin 1, eater, and prophenoloxidase were normalized to the geometric mean of the housekeeping gene actin and eIF 3 -S8 using the comparative quantification method (delta Ct method) for genes. Those housekeeping genes were previously found to remain unchanged upon heat stress 42 . For DWV, external standards of known concentration were obtained from 10-fold serial dilutions and used for absolute quantification.…”

Since climate change is expected to bring more severe and frequent extreme weather events such as heat waves, assessing the physiological and behavioural sensitivity of organisms to temperature becomes a priority. We therefore investigated the responses of honeybees, an important insect pollinator, to simulated heat waves (SHW). Honeybees are known to maintain strict brood thermoregulation, but the consequences at the colony and individual levels remain poorly understood. For the first time, we quantified and modelled colony real-time activity and found a 70% increase in foraging activity with SHW, which was likely due to the recruitment of previously inactive bees. Pollen and nectar foraging was not impacted, but an increase in water foragers was observed at the expense of empty bees. Contrary to individual energetic resources, vitellogenin levels increased with SHW, probably to protect bees against oxidative stress. Finally, though immune functions were not altered, we observed a significant decrease in deformed wing virus loads with SHW. In conclusion, we demonstrated that honeybees could remarkably adapt to heat waves without a cost at the individual level and on resource flow. However, the recruitment of backup foraging forces might be costly by lowering the colony buffering capacity against additional environmental pressures.

“…Numerous studies agree that synergetic interactions between multiple abiotics (Doublet et al, 2014;Alburaki et al, 2015;Kakumanu et al, 2016;Poquet et al, 2016;Li et al, 2017;López et al, 2017) and biotics stressors (Goulson et al, 2015;Dussaubat et al, 2016) are involved as major causes of bee colonies decline (see also reviews by Fairbrother et al, 2014;Alberoni et al, 2016;Sánchez-Bayo et al, 2016;Klein et al, 2017). Synergies between many of these factors have a strong negative impact on immune defense (Nazzi et al, 2012;Di Prisco et al, 2013), metabolism (Koch and Schmid-Hempel, 2011;Dussaubat et al, 2013;Bordier et al, 2017), and on bees cognitive mechanisms (Klein et al, 2017). Now, honey bee gastrointestinal microorganisms (i.e., gut microbiota) are known to play a critical role in regulating specific functions associated with metabolism and immune response (Evans and Lopez, 2004;Alberoni et al, 2016;Hyrsl et al, 2017).…”

“…When the internal hive temperature exceeded the ideal range for brood development (i.e., 33 and 40 ° C treatments), workers probably sought to intensify the convective heat loss by fanning over the brood area (Southwick & Heldmaier, 1987;Southwick & Moritz, 1987;Starks & Gilley, 1999). According to Bordier et al (2017), heat-challenged workers bees show a nurse-like profile as a result of increased expression of specific genes. The activation of fanning behavior and the ability of nest cooling by workers arepositively influenced by intracolonial genetic diversity (Jones et al, 2004;Graham et al, 2006;.…”

Bees play an important role in maintaining biodiversity by promoting the pollination of numerous plant species. Recent global climate changes are affecting the average air temperature, thereby altering the biological processes of many species. The objective of this study was to evaluate the adaptation of Apis mellifera L. bees to temperature increases and their responses to thermal homeostasis in the colony. Research was performed at the Federal University of Paraíba Laboratory of Bees using three treatments: Control, 33 °C and 40 °C. For the latter two treatments, colonies were kept in a 24 m² climate chamber with an opening at the hive entrance, giving the bees access to the outside environment. The following parameters were evaluated: difference between internal and external hive temperature, thorax surface temperature and total protein concentration in the hemolymph. Internal colony temperature varied according to the external hive temperature. Nurse bees that care for larvae exhibited higher heat production, expressed as thorax surface temperature. Total protein content in the hemolymph was highest in the 40 °C treatment and decreased with ambient temperature. External hive temperature influences internal hive temperature, and nurse bees have higher capacities for thermogenesis.
