“…The activity take place, in late hours on the morning (10:00 -11:00 h) and in afternoon (15:30 -17:30 h), when temperature is suitable and the weather is warm which is coincided with the result of this study. High temperature at noon is a major reason for the decline in the flights which has been observed in various solitary bee species (Herrera, 1990), in addition to dehydration at high temperature (Pierrot and Schlindwein, 2003;Zohdy and Rahman (2015) and Harano 2020).…”

Most of the human food resources depend on honeybees; they are the most efficient pollinators that contribute to our ecosystem stability, biodiversity and crop productivity. Honeybees' foraging behavior is affected by many environmental factors. Daytime, ambient temperature and food availability (nectar and pollen) are the most influencing factors on foraging behavior. Many ecological studies were done to study this behavior, in addition to its seasonal and monthly abundance. In this study, honeybees' foraging activities, as well as their seasonal and monthly abundance were studied and evaluated. The study was run during the period of 12/2017-11/2018. All beekeeping managements were provided to retain the colony in good condition during the period of the experiment. The obtained results revealed that honeybees have a bimodal daily foraging activity pattern with morning and afternoon peaks. The daily activity pattern of honeybees showed a significant correlation with the measured temperature. Meanwhile, the seasonal abundance of forager bees changed significantly among different seasons with the highest abundance peak during spring. Results also suggest that the honeybees' activity had a microclimatic window of opportunity for ambient temperatures within which foraging flight can be continued, where their forage temperature was fallen within the range of 20°C to 28°C.

“…Importantly, and in contrast to most solitary insects, honey bee foragers, which are the older bees in the colony, have a reduced fat body 22 with low glycogen reserves compared to younger nest bees 23 and experience a significant reduction in abdominal lipids in the transition that precedes the onset of foraging 24 . To sustain the energetic demands of foraging flights, forager bees load in the crop minute amounts of honey before departing from the hive, which serve as fuel for the rest of the foraging bout 21 , 25 , 26 . As long as sugar is present in their crops, bees keep flying for food; yet, they stop flying as crop carbohydrates disappear 27 .…”

Adipokinetic hormone (AKH), energy budget and their effect on feeding and gustatory processes of foraging honey bees

The adipokinetic hormone (AKH) of insects is considered an equivalent of the mammalian hormone glucagon as it induces fast mobilization of carbohydrates and lipids from the fat body upon starvation. Yet, in foraging honey bees, which lack fat body storage for carbohydrates, it was suggested that AKH may have lost its original function. Here we manipulated the energy budget of bee foragers to determine the effect of AKH on appetitive responses. As AKH participates in a cascade leading to acceptance of unpalatable substances in starved Drosophila, we also assessed its effect on foragers presented with sucrose solution spiked with salicin. Starved and partially-fed bees were topically exposed with different doses of AKH to determine if this hormone modifies food ingestion and sucrose responsiveness. We found a significant effect of the energy budget (i.e. starved vs. partially-fed) on the decision to ingest or respond to both pure sucrose solution and sucrose solution spiked with salicin, but no effect of AKH per se. These results are consistent with a loss of function of AKH in honey bee foragers, in accordance with a social life that implies storing energy resources in the hive, in amounts that exceed individual needs.
