Now Honeybees Can Be Monitored in Winter through Robotic Bio- hybrid Systems


The waggle dance of the bees, according to the experts, is their mode of communication. The female bee uses it to encode the food-finding clue for the colony bees. Waffling is important. When a honeybee finds food, perhaps kilometers away, her colony mates can fly there thanks to the hints encoded in her rump-shimmy sprints and turning loops. However, five colonies in the current test lacked older sisters or half-sisters to serve as dance move role models.

But, as the kids wiggled and looped day after day, the dances got better in some aspects. Nevertheless, Apis mellifera (the western honey bee) lacking role models failed to match the timing and coding in typical colonies, in which the young bees practiced with older foragers before performing the major waggle on their own.

According to the researchers, the young-only colonies thus demonstrate that social learning, or lack thereof, matters for honey bee dance communication. Like songbird or human communication, bee waggle dance appears both innate and taught. It required complex beekeeping to test for social learning. Researchers at an apiary research facility in Kunming, China, placed thousands of honeybees in incubators when they were at the stage known as purple-eyed pupae and then collected the newly emerging winged adults.

Foraging bees who practice waggle dancing must learn both the moves and the challenges of the honeycomb dance floor. Cells could be empty. There are only the edges to hold on to. It would be simple to slip up. In contrast to industrial hives with artificially homogeneous honeycomb cells, natural combs are quite irregular. They start to get a little crazy and rough around the edges, according to the researchers.

Our robotic device allows us to modify the temperature from within the cluster, simulating the heating behavior of the bees within and letting us examine how the winter cluster actively manages its temperature

Honeybees are incredibly fascinating insects. Their waggle dance can be used to teach robots how to communicate, and they can navigate utilizing highways. However, it is challenging to study them since bee colonies can become confused by research tools or even strange odors.

Robots to Monitor the Behavior of Honeybees
Researchers from the University of Graz in Austria have joined forces with academics from the École Polytechnique fédérale de Lausanne (EPFL) in Switzerland to create a robotic system that can be constructed in the form of a honeybee hive. The device, consisting of several thermal sensors and actuators, uses localized temperature differences to monitor and control honey bee behavior. Researchers claim that the many norms of bee society, from interpersonal interactions to raising a healthy brood, are regulated by temperature.

The thermal sensors provide a snapshot of the bees' collective behavior, and the actuators in the system enable the researchers to control the bees' movement. Honeybees don't hibernate or go inactive over the winter like many other insects do. According to reports, they maintain a warm microclimate inside the hive throughout the winter and subsist entirely on the honey they have hoarded. By working out, the bees keep themselves and their night’s warm, which can be done through the exercises.

All of the bees in the hive flap their wings while not flying or exercising them. Similar to how leaving the engine in neutral will warm up an automobile engine. The bees keep the valuable heat they produce by doing this in the nest by allowing only tiny openings. To fill in gaps and repair cracks, they employ plant resins and gums. They then form a circular mass of bees.

Honeybees in Winter
As we already know, honeybees are categorized as workers, drones, and queens. In winter, male drones die off, leaving the female ones. The all-female flock of bees crowds together tightly to form the winter cluster, with the queen at the warmest core section of the group and the workers shaking and shivering around to maintain a survivable heat. They can maintain a temperature above 10 degrees Celsius in the hive's outermost regions by performing all of these things. A study that appeared in the Journal of Invertebrate Pathology anticipated that the western honey bee's lowest operating temperature would be approximately 15 degrees Celsius. Below that, the small companion of man finds it difficult to survive.

Earlier research on the thermal behavior of honeybees in winter watched the bees by adjusting the ambient temperature. However, the new method enables scientists to modify the temperature inside the cluster. This is more in line with how bees actually act in the winter.

Martin Stefanec, a scientist at the University of Graz, says that "Our robotic device allows us to modify the temperature from within the cluster, simulating the heating behavior of the bees within and letting us examine how the winter cluster actively manages its temperature."

The study of bee colonies is fairly challenging in and of itself. Yet because they are sensitive to the cold, researching them in the winter is considerably more challenging. Nonetheless, they analyzed three experimental hives at the University of Graz in Austria while operating them remotely from EPFL in Switzerland using the new robotic devices.

The researchers were able to learn where the bees were in the hive using the robotics system, and they were able to urge the bees to move around by using the actuators. When they like to snuggle together in the winter to preserve energy, bees typically don't do much of that.

In a sense, the researchers had the authority to speak for the colony. For instance, they might steer the bees toward food sources. Interestingly, using actuators allowed the researchers to extend a colony's life following its queen bee's death.

The researchers claim that such biohybrid devices that allow access could be utilized to improve bees' survival. This could be especially helpful in a world where critical pollinator populations, like bee populations, are in trouble. This could have significant effects on food security.
