![]() Extensive research has been aimed at disentangling the complex metabolic pathways and interactions among the cells in our body and our microbial commensals and the myriad chemical compounds they produce and exchange. ![]() In recent years, interest in the roles of gut microbes has surged. "Like the worker bee, it loses the probiotic species like Bifidobacterium and Lactobacillus and gains a variety of Proteobacteria, and those changes are intimately tied to our health." "The aging human gut goes through the same exact thing," he says. Queens on the other hand, somehow manage to support a more refined, efficient microbiome, retaining "signatures of youth," as Anderson puts it. Similar to the physiology of aging, the researchers discovered that queen and worker bees embark on different microbial trajectories: as workers age, their gut microbiomes shift away from the initial dominance of beneficial, probiotic microbes, and their intestines are taken over more and more by bacteria associated with poor health and shorter life expectancy. There appears to be a similar trend in worker bees, leading the researchers to hope that bees could be used as model organisms to study the more complex assemblies of microbes that make up the microbiome in mammals, including humans. This allowed them to compare the bacteria that make up the gut flora in aging workers versus aging queens.Ī growing body of research suggests that in humans, so-called probiotic bacteria like Bifidobacterium and Lactobacillus are associated with health and longevity, whereas bacteria belonging to a group known as Proteobacteria often are associated with unhealthy microbial imbalances. Taking advantage of the UA’s next-generation sequencing capabilities, Anderson's team identified the species and amounts of bacteria living in honey bee intestines. The group published their results earlier this month in the high-tier scientific journal Microbiome. The study resulted from an interdisciplinary collaboration between the UA, the UA’s BIO5 Institute and the Carl Hayden Bee Research Center, which is operated by the Agricultural Research Service of the U.S. Anderson is also an adjunct scientist in the Department of Entomology and Center for Insect Science in the UA's College of Agriculture and Life Sciences. "Our study is the first to suggest a connection between the bacteria that inhabit the bees’ guts, the foods they eat, and physiological differences related to aging, stress and longevity," says Kirk Anderson, a research microbiologist with the Carl Hayden Bee Research Center in Tucson, Arizona. The observed differences in gut bacteria populations, called microbiomes, could be a clue in a mystery that has vexed scientists for a long time: In two genetically identical castes, why do worker bees die after mere weeks whereas queens can live years? To the untrained eye beholding a beehive, all animals seem equal, but new research reveals that some are more equal than others.Ī team of researchers including three graduate students at the University of Arizona discovered that while worker bees and queens can be genetically identical, their vastly different lifespans appear to be connected to different microbes living in their guts. ![]() During the last few weeks of its life they collect food, gather pollen or nectar.The queen bee, recognized by her larger size and marked with a red dot so the scientists can keep track of her more easily, can live for years, while the worker bee's lifespan is measured in weeks. During the first few weeks of its life they live in the hive. Note: The worker bees are sterile but can develop ovaries in the absence of a queen. Thus the correct answer is (C) Worker female bees can live up to 45 days. The lifetime of worker bees is around 45 day. The worker bees work without pause in their lifetime. They do various tasks like feed brood, receive nectar, clean hive, guarding. There are around 60000 worker bees in a single colony. They have royal jelly producing glands which help in making the honeycomb. They produce royal jelly on which the Larvae feed. Queens can live several years.Ģ) Drone bees or males -The unfertilised eggs develop into drones which are haploid.ģ) Female worker bees- Developed from the fertilised egg. The larvae fed solely on royal jelly forms queens. In the colonies, three types of honey bees are found.ġ) Queen bee- The colony contains only one queen bee which is female. The wax obtained from the bee hive is used in cosmetics. Hint: Honey bee is a flying insect belonging to genus Apis.
