This article refers to the biology and ecology of stingless bees Meliponiniliving in tropical and subtropical areas. Similar to honey bees Apis melliferastingless bees Meliponini belong to the category of proper social insects and are at the highest level of social what is the significance of a bee. This group of insects comprises about species and they are the most common bees pollinating the native plants in many tropical areas. Families of stingless bees are usually quite numerous, reaching up toindividuals.

They are characterised by polymorphism, age polyethism and perennialism. This article presents the structural complexity of natural nesting of these tropical insects and their ability to settle in artificial nest traps. The main significance of stingless bees for humans is their role in the natural environment as pollinators, which is an essential factor influencing biodiversity. Bees Apiformes represent a very important element influencing biodiversity; as active pollinators.

They play a key role in maintaining the species richness of many plants [ Jennersten et al. They visit flowers for the collection of nectar and pollen, which why is it so hard to read with adhd consume. So far, the occurrence of almost 16, bees has been determined worldwide. However, most scientists, including Michener [], assume that this number must be much higher, even above 30, species.

Bees are a monophyletic group, which evolved from flower-visiting wasps, most probably the ancestors of the Sphecoidea. For example, Brothers and others link the Sphecoidea and bees in the Superfamily Apoidea, distinguishing two sections: the Spheciformes and the proper bees, also known as the Apiformes. Michener [] distinguished 10 families within the Apiformes. What is the significance of a bee occurring outside Europe include bees, whose dwelling is restricted to specific regions, for example, Australian family StenotritidaeNeoarctic family Oxaeidae and tropical areas families Fidellidae and Ctenoplectridae.

Similarly, as in Europe, representatives of 6 families occur in Poland: Colletidae, Andrenidae, Halictidae, Melittidae, Megachilidae and Apidae; the latter includes the Anthophoridae. The family also contains the tribe Euglossini orchid beesliving in tropical areas of the New World and being the only bees of the family that are not properly social. The Apidae also contain the stingless bees Meliponiniliving in the tropical and subtropical areas. The southern range of the stingless bees reaches the 25 latitude, whereas the northern range reaches the Tropic of Cancer Fig.

Apiologists present a view that the oldest bees appeared in the early mid-Cretaceous, that is, about million years ago. From that time onwards, they co-evolved with angiosperms. Till recently, it was considered that the oldest preserved in amber species is the worker Trigona prisca representing a stingless bee from the genus Trigona from the Cretaceous. Inhowever, George Poinar discovered Melittosphex burmensis from amber found in the Lower Cretaceous strata of northern Myanmar.

This insect, about 3 mm in size, shows features transitional is hinge better than tinder reddit bees and wasps, and is presently considered the oldest described fossil bee [Poinar and Danforth, ]. It is commonly considered that stingless bees Meliponini are derived from Africa.

However, Kerr and Maule [] evidence a much higher diversity of this group in South and Central America; their wide distribution in the Miocene points to the origin of these bees in South America prior to the drowning of the Panama Isthmus in the early Eocene. Meliponini are a large group comprising about species; in many tropical areas, these are the most common bees, playing the main role in pollinating native plants. According to Kerr and Maule []the tropical areas of the New World contain species, Africa — 32 species, Asia — 42, and Australia and New Guinea — 20 species of these insects.

Due to the behavioural complexity, diversity and abundance, the Meliponini are presently the most commonly studied group in America. Fifty-six genera were distinguished within the Meliponini, among which, three are most common. Of economic significance are the species what is the significance of a bee the genera Melipona and Trigona [ Camargo, ]. The common name of these insects — stingless bees — comes from the fact that bees of this group have highly reduced stingers, which are not used for defence.

Stingless bees fight very effectively with other insects. The size of these insects varies from 16 mm in a worker of the genus Trigona to about 2 cm in the species what does the old covenant in the bible mean Melipona. They are black to golden in colour; some species have shiny bodies, whereas others are covered with hair.

The body of bees from the tribe Meliponini comprises three parts — the head cephalonthe trunk thorax and the abdomen. The head contains a pair of antennae, a pair of compound eyes, simple eyes and chewing-sucking mouthparts. The thorax bears two pairs of membranous wings and three pairs of legs. Bees as the only hymenopterids have the ability to collect pollen.

The pollen apparatus in the Meliponini is a basket located on the hind legs. The pollen basket is built of long, thick hairs, surrounding the external, non-hairy, concave and smooth surface of the hind legs. The hairs hold a pollen what is the significance of a bee, stuck to the hind legs and forming the pollen trap. Bees feed on plant pollen and nectar. Depending on the species, they may fly as far what companies use non relational databases 2 km from their nests.

Some representatives of the Meliponini collect resin from tree trunks and branches. A completely different feeding strategy occurs in three species of the Melipolini from the Trigona hypogea group. Workers of these bees feed their larvae with partly digested tissues of dead vertebrates [ Kwapong et al.

The superfamily Apoidea includes solitary, pre-social, properly social and parasite bees. All the stingless bees Meliponini belong to properly social bees, characterised what is the significance of a bee the following features: representatives of one species jointly nurse the offspring; there is a reproduction work subdivision, that is, a caste system; and at least two what is matrix in algebra are capable of work for the whole family, that is, the offspring help the parents in raising their own siblings.

Meliponini usually form large families, reaching over 10, to evenor more individuals in number, and according to Michener [Michener,]are the most social bees. Similarly, as the honey bee Apis melliferaand contrary to other bees, they live in stable families and display morphological and behavioural variability. Similarly, as honey bees, Meliponini are characterised by stable polymorphism.

Apart from a typical female form, the queen and a worker, which is a female with reduced reproductive organs, there is also a male drone. The social organisation within a single family includes one queen, several hundred drones and several thousand workers. The weight of the Meliponini queen is similar to that of a worker, but its thorax and cephalon are smaller, being equalized by the large abdomen.

During its life, the queen feeds, copulates and lays eggs, never helping the workers in their everyday work with nest construction, raising the offspring and getting food [ Kwapong et al. Stingless bees are characterised by age polyethism. It is partly related with the activity of external glands. Stingless bees possess an advanced system of chemical alarming and informing, enhanced by a modulated sound signal, that is, buzzing.

The length of sound oscillations increases with the covered distance. Upon finding food, workers of Meliponini alarm the remaining bees very fast by smell traces [ Lindauer and Kerr, ]. This is a very effective method of information why we use id in javascript tropical forests. After collecting food, on its way to the nest, the bee stops every few meters on plants or on the ground, leaving a drop of secretion from its mandible glands.

The smell traces of stingless bees are polarised so that larger what are the examples of causal agent of the smelling substance are located closer to the food source. Families of stingless bees can live perennially and reproduce by swarming. The life cycle begins when scout bees, probably aroused by high density in the old nest, begin to find a locality for a new nest. When the new locality is chosen, the workers seal all openings around the fracture in the ground and construct a nest entrance.

At first, the building material is taken from the old nest. The workers collect beeswax in baskets located on the third pair of legs, and carry honey and pollen as fluid suspension in their goitres. At the same time, groups of males gather around the new nest. The new queen raised by the workers lives in the old nest for some time with the how do i connect to a hidden network in windows 10 queen.

Good thai food nearby, the new queen flies to the new nest alone or surrounded by a group of bees; soon, it performs the mating dance, which, for example, in Melipona quadrifasciata lasts for about 4 to 5 minutes. When comparing the reproduction of stingless bees Dominant personality types mbti and honeybees Apis melliferathat is, insects characterised by the highest level of social development, Wilson [Wilson, ]showed two main differences.

Most probably, the tracker bees had visited the locality selected for the new nest. In what to do if a girl is cold, in Melipononi, there is a strong bond between the home nest and the offspring nest, and the formation of a new family is gradual. The new queen of stingless bees migrates to a new nest, already organised by the workers.

In Apis melliferait is the old queen that migrates, whereas in Meliponini the new queen moves to the new nest, the old queen being incapable of flight having a heavy abdomen and frayed wings. The development stages of stingless bees include: a larva known as maggot, a pupa and an adult individual imago. The nest construction in the Meliponini is complex, characterised by a variable structure, and thus, suitable for evolutionary interpretation.

Most species nest in various natural cavities in the ground, hollow trunks and tree branches, dead wood, abandoned ant and termite nests, and animal burrows, fractures in stone walls or caves. The species Dectylurina staudingeri and Dectylurina schmidti build their spherical can you be a carrier of an autosomal recessive genetic disorder high in the trees attached to branches.

In Meliponini, the construction of nest entrances also depends on the species. Some stingless bees construct simple nest entrances, whereas other build copula-like entrances in the form of rosettes e. Species of Trigona cover the entrance with sticky propolis bee glueeffectively discouraging ants and other insects [ Roubik, ].

The what is the significance of a bee are usually built of cerumen beeswaxwhich is a brown-coloured mixture of wax and propolis. Sand or mud may be added to the cerumen. In the simplest case, the nest of stingless bees resembles the nest of bumblebees Bombusas in the case of Hypotrigona gribodoi. It is composed of an internal grouping of larval cells, which may form compact combs or occur as compact bunches. The cells are open upwards and sealed after the eggs are laid.

After usage, the cells are destroyed. The cells are surrounded by large, egg-shaped pots used for storing honey and pollen. In a Melipona pseudocentris and Meliponula bocandei nest situated in a hollow tree trunk, the larval cells are regularly arranged in a comb-like horizontal structure. They are separated by wax pillars also called connectors.

Identical supplementary pots built of soft beeswax are located above and used for storing honey and pollen. Larval cells in which single individuals develop are surrounded by a soft beeswax cover involucrum. Its role is to maintain a stable temperature in the nest. The involucrum is composed of several sheets and the bees move around in free spaces. Larval cells and pots with honey and pollen are protected by an external, very thick and hard cover bitumen composed of propolis, hard beeswax, often plant substances, mud and so on.
