In [[Mesoamerica]], the [[Mayans]] have practiced large-scale intensive meliponiculture since pre-Columbian times. [36] => [37] => == Evolution == [38] => The immediate ancestors of bees were [[Aculeata|stinging wasp]]s in the family [[Crabronidae]], which were [[Predation|predators]] of other insects. The switch from insect prey to pollen may have resulted from the consumption of prey insects which were flower visitors and were partially covered with pollen when they were fed to the wasp larvae.

[39] => [40] => Based on phylogenetic analysis, bees are thought to have originated during the [[Early Cretaceous]] (about 124 million years ago) on the supercontinent of [[Gondwana|West Gondwana]], just prior to its breakup into [[South America]] and [[Africa]]. The supercontinent is thought to have been a largely [[Deserts and xeric shrublands|xeric]] environment at this time; modern bee diversity hotspots are also in xeric and seasonal temperate environments, suggesting strong [[Phylogenetic niche conservatism|niche conservatism]] among bees ever since their origins.{{Cite journal |last1=Almeida |first1=Eduardo A.

The [[Melittidae]], [[Apidae]], and [[Megachilidae]] had already evolved on the supercontinent prior to its fragmentation. Further divergences were facilitated by West Gondwana's breakup around 100 million years ago, leading to a deep Africa-South America split within both the Apidae and Megachilidae, the isolation of the Melittidae in Africa, and the origins of the [[Colletidae]], [[Andrenidae]] and [[Halictidae]] in South America. The rapid radiation of the South American bee families is thought to have followed the concurrent radiation of [[flowering plant]]s in the same region. Later in the Cretaceous (80 million years ago), colletid bees colonized [[Australia]] from [[South America]] (with an offshoot lineage evolving into the [[Stenotritidae]]), and by the end of the Cretaceous, South American bees had also colonized North America. The North American fossil taxon ''[[Cretotrigona]]'' belongs to a group that is no longer found in North America, suggesting that many bee lineages went extinct during the [[Cretaceous–Paleogene extinction event|Cretaceous-Paleogene extinction event]]. [43] => [44] => Following the K-Pg extinction, surviving bee lineages continued to spread into the Northern Hemisphere, colonizing [[Europe]] from Africa by the [[Paleocene]], and then spreading east to [[Asia]]. This was facilitated by the warming climate around the same time, allowing bees to move to higher latitudes following the spread of tropical and subtropical habitats.

The number of eggs laid by a female during her lifetime can vary from eight or less in some solitary bees, to more than a million in highly social species.[https://books.google.com/books?id=bu_1gmY13FIC&dq=eggs+laid+during+her+lifetime+eight+or+fewer+solitary+million+queens&pg=PA8-IA12 The Bees of the World, Volum 1] Most solitary bees and bumble bees in temperate climates overwinter as adults or pupae and emerge in spring when increasing numbers of flowering plants come into bloom. The males usually emerge first and search for females with which to mate. Like the other members of Hymenoptera bees are [[Haplodiploidy|haplodiploid]]; the sex of a bee is determined by whether or not the egg is fertilised. After mating, a female stores the sperm, and determines which sex is required at the time each individual egg is laid, fertilised eggs producing female offspring and unfertilised eggs, males.

They have short horns on the head, jaws for chewing food and an appendage on either side of the mouth tipped with a bristle. There is a gland under the mouth that secretes a viscous liquid which solidifies into the silk they use to produce a cocoon. The cocoon is semi-transparent and the pupa can be seen through it. Over the course of a few days, the larva undergoes metamorphosis into a winged adult. When ready to emerge, the adult splits its skin dorsally and climbs out of the [[exuvia]]e and breaks out of the cell.

Specific fungi, such as [[Zygosaccharomyces]] sp, [[Candida (fungus)|Candida sp]]., and [[Monascus]] ruber, produce chemicals that fight against [[bacteria]], [[fungal infection]]s from different species, and [[virus]]es. Recently these types of bees have been observed eating [[mycelium]], suggesting that honey bees have been “foraging [[mushroom]]s to collect [[antimicrobial]] medicine to boost their collective [[Immunity (medical)|immunity]]”.{{Cite web |last=White |first=Katie |date=2022-02-02 |title=Curious about Fungi and Honey Bees? |url=https://bestbees.com/2022/02/02/fungi-and-honey-bees/ |access-date=2023-04-25 |website=bestbees.com |language=en-US}} Without these vital nutrients, honey bee morbidity rates rise, and the possibility of [[fungal infection]]s can spike, leading to unhealthy bee hives and honey shortage. [[Fungal infection]]s can also lead to [[colony collapse disorder]], so the ingestion of [[mycelium]] lowers the morbidity rate of honey bees by preventing those [[fungal infection]]s from happening. [[Colony collapse disorder]] (CCD) is when worker bees abandon the [[queen bee]] and leave behind the brood and a few nurse bees. This however is not enough to sustain a hive as workers are required to construct and maintain the hive structure as well as produce honey. [[Colony collapse disorder]] can also happen when [[Varroa Mites|varroa mites]] infiltrate a hive. These mites will attack and eat bees inside a hive, making it impossible for them to continue to reproduce and make [[honey]]. The presence of [[Varroa destructor|varroa mites]] results in a decrease in bee population, deformed bees, an inability to reproduce on the bees part, and overall weakening of the colony. [[Varroa Mites|Varroa mites]] are only capable of reproducing inside of a honey bee colony, posing an even greater threat if they are able to infiltrate because it will destroy their home. [[Mycelium]] has been shown to [[Germination|germinate]] inside of [[Varroa Mites|varroa mites]] and grow from the inside out, killing the mites and protecting the bees. The extermination of mites by [[mycelium]] is a better alternative to [[pesticide]]s that have shown to be toxic towards the bee colony. [[Mycelium]] also plays a role in boosting [[anti-inflammatory]] and [[Antimicrobial resistance|antibacterial resistance]] in bees due to the [[ecdysteroid]]s and [[Zygosaccharomyces]] found in [[mycelium]], which are then fed to [[larva]]e, boosting the next generations immunity and improving overall hive health. [[Zygosaccharomyces]] are “spoilage yeasts that have an extreme resistance to acids and preservatives” and can “tolerate high concentrations of sugars and salts”.{{Cite web |title=Zygosaccharomyces - an overview {{!}} ScienceDirect Topics |url=https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/zygosaccharomyces#:~:text=Zygosaccharomyces%20bailii%20is%20characterized%20by,delbrueckii%20of%20diverse%20physiological%20properties.%20(Accessed:%20March%2020,%202023). |access-date=2023-04-25 |website=www.sciencedirect.com}} Honey bees depend on this source of steroids to allow them to develop properly during insect [[Pupa|pupation.]] [269] => [270] => ==== Bee broods ==== [271] => The [[Symbiosis|symbiotic]] relationship between bees and [[mycelium]] is found primarily in Brazilian stingless bees and Malaysian stingless bees - or more commonly honey bees. [[Bee brood]]s are the [[larva]]e of honeybees. They can typically be found inside of a bee hive, and in man made hives especially, the honeybees can be found developing at different stages (eggs, larvae, and [[pupa]]e) inside a [[Honeycomb|hexagonal shape]]. Bee larvae are incapable of producing [[steroid]]s at birth, so they ingest [[mycelium]] to receive vital nutrients they cannot create on their own such as [[ecdysteroid]]s and Zygosaccharomyces sp.{{Cite journal |last1=Paludo |first1=Camila Raquel |last2=Pishchany |first2=Gleb |last3=Andrade-Dominguez |first3=Andres |last4=Silva-Junior |first4=Eduardo Afonso |last5=Menezes |first5=Cristiano |last6=Nascimento |first6=Fabio Santos |last7=Currie |first7=Cameron R. |last8=Kolter |first8=Roberto |last9=Clardy |first9=Jon |last10=Pupo |first10=Mônica Tallarico |date=2019-07-25 |title=Microbial community modulates growth of symbiotic fungus required for stingless bee metamorphosis |journal=PLOS ONE |language=en |volume=14 |issue=7 |pages=e0219696 |doi=10.1371/journal.pone.0219696 |issn=1932-6203 |pmc=6657851 |pmid=31344052 |bibcode=2019PLoSO..1419696P |doi-access=free }} Once the honey bee eggs hatch, a white microbial film starts to grow on the boundary between the brood cell and the larval food supply, and is then ingested by the [[larva]]e to complete their development.

Three studies were recently conducted and each introduced a new organism to the bees [[gut microbiota]]. The bees were fed aged [[pollen]], the assembly of the [[gut microbiota]] was disturbed, and antibiotic tetracycline entered their diet.

[274] => [275] => ==== Bee-fungus symbiosis ==== [276] => As mentioned above, honey bees cannot produce [[steroid]]s themselves, they must be ingested through their diet, specifically in the early development process. Larvae eat the fungus and the [[ecdysteroid]]s and [[Zygosaccharomyces]] produced by the [[mycelium]] benefit the [[larva]]e. [[Ecdysteroid]]s are naturally occurring [[steroid]]s found in [[mycelium]] and they help enhance performance and reproduction, boosting honey production and keeping the hive population running at a stable rate. “[[Zygosaccharomyces]] sp. is essential for S. depilis larvae”. These [[sterol]]s thus have a high impact on the survival rate of honey bees. Their ingestion determines whether the honey bees will be able to protect themselves against [[fungal infection]]s, [[virus]]es, and whether or not they will have sufficient strength to increase honey production and the ability to [[Pollination|pollinate]] a larger area and more frequently. [277] => [278] => Knowledge of how [[mycelium]] boosts honey bees immunity could be pivotal to the increase of a honey bee's lifespan and boost reproduction by helping implement new policies to prevent the use of harmful [[pesticide]]s. [279] => [280] => ==== Impact of pesticides ==== [281] => [[Pesticide]]s have been diminishing the bee population recently due to a lack of regulations regarding what can and cannot be sprayed on produce to protect it from being damaged during growth. When honey bees collect [[pollen]] and [[nectar]] for nutrition and to make [[honey]], they are also ingesting harmful chemicals. Such chemicals take a toll on the honey bees' already sensitive [[Gut microbiota|gut microbiome]] and lead to a higher morbidity rate in honey bees.

More about us

About

They are known for their role in pollination, which is crucial for the reproduction of many plant species. There are over 20,000 known species of bees, found on every continent except Antarctica. Bees are social insects, living in colonies that consist of a queen, female workers, and male drones. The queen is responsible for laying eggs and is the only sexually reproductive individual in the colony. The workers, which are infertile females, perform various tasks such as foraging for food, building and maintaining the nest, and caring for the young. Male drones are produced only during the breeding season and their sole purpose is to mate with the queen. Bees have a specialized diet consisting mainly of nectar and pollen. They have evolved adaptations to collect and transport these resources, such as elongated mouthparts for sipping nectar and hairy bodies for pollen collection. Bees are also known for their ability to communicate through a complex system of dance-like movements known as the "waggle dance. " This dance conveys information about the location of food sources to other members of the colony. In recent years, bees have faced numerous challenges, including habitat loss, pesticide use, and climate change. These factors have led to a decline in bee populations, with some species being listed as endangered. This decline is concerning because bees play a crucial role in pollinating crops and wild plants, which is essential for food production and ecosystem stability. Efforts are being made to protect and conserve bees, such as creating bee-friendly habitats, reducing pesticide use, and raising awareness about their importance. Additionally, beekeeping has become a popular hobby and industry, providing pollination services and producing honey and other bee-related products. Overall, bees are fascinating creatures that play a vital role in our ecosystems. Understanding and protecting these important insects is crucial for the health and well-being of both humans and the environment.
