Sniffer bees or sniffer wasps are insects in the order Hymenoptera that can be trained to perform a variety of tasks to detect substances such as explosive materials or illegal drugs, as well as some human and plant diseases. The sensitivity of the olfactory senses of bees and wasps in particular have been shown to rival the abilities of sniffer dogs, though they can only be trained to detect a single scent each.
Ethologist Karl von Frisch dedicated much of his career to the study of the sensory perceptions of the honey bee and was one of the first people to translate the meaning of the waggle dance. [1] His studies show that bees can count to five and have the capacity to be trained to visit specific feeding stations at certain times of day. [2]
Bees and wasps are trained using classical conditioning, being exposed to a particular odour and then rewarded with a sugar solution. [3] Within five minutes they learn to associate the smell with an impending supply of food and this triggers the proboscis extension reflex (sticking out their tongues). [4]
Trained hymenopterans have been shown to successfully detect explosive materials including TNT, Semtex, and C-4 as well as gunpowder and propellants. [3] [5] Wasps can be trained to detect the early signs of fungal disease on crops and may have medicinal value, identifying people with cancer just by being exposed to their breath. [6] Bees have been shown to detect and respond to more than 60 different odours including methamphetamine, uranium, and tuberculosis. They have been used to detect lung and skin cancers, diabetes, and to confirm pregnancy. [2] It is not known if they can detect potential seizures in humans.
Researchers at the University of Georgia have built a device named the "Wasp Hound" which contains the parasitic wasp species Microplitis croceipes . The insects normally walk around the PVC pipe in which they are housed but begin to migrate towards the source of an odour when it is the one that they were trained to recognise. These movements are tracked by a computer, with small cameras inside the device sending images for processing. Within 30 seconds of the wasps beginning to congregate near an odour source an alarm is sounded. [7]
Bees are winged insects closely related to wasps and ants, known for their roles in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey. Bees are a monophyletic lineage within the superfamily Apoidea. They are currently considered a clade, called Anthophila. There are over 20,000 known species of bees in seven recognized biological families. Some species – including honey bees, bumblebees, and stingless bees – live socially in colonies while most species (>90%) – including mason bees, carpenter bees, leafcutter bees, and sweat bees – are solitary.
A honey bee is a eusocial flying insect within the genus Apis of the bee clade, all native to mainland Afro-Eurasia. After bees spread naturally throughout Africa and Eurasia, humans became responsible for the current cosmopolitan distribution of honey bees, introducing multiple subspecies into South America, North America, and Australia.
While observers can easily confuse common wasps and bees at a distance or without close observation, there are many different characteristics of large bees and wasps that can be used to identify them.
Bee learning and communication includes cognitive and sensory processes in all kinds of bees, that is the insects in the seven families making up the clade Anthophila. Some species have been studied more extensively than others, in particular Apis mellifera, or European honey bee. Color learning has also been studied in bumblebees.
A stinger is a sharp organ found in various animals capable of injecting venom, usually by piercing the epidermis of another animal.
The Russian honeybee refers to honey bees that originate in the Primorsky Krai region of Russia. This strain of bee was imported into the United States in 1997 by the USDA Agricultural Research Service's Honeybee Breeding, Genetics & Physiology Laboratory in Baton Rouge, Louisiana, in response to severe declines in bee populations caused by infestations of parasitic mites, and has been used in breeding programs to improve existing stocks. Many Russian queens openly mate with drones from various stock, creating colonies that are genetically hybrid. Some of these 'uncontrolled' hybrids may exhibit "increased aggressiveness, reduced honey production and a decrease in their ability to withstand mites and detrimental expressions of other traits as well."
Waggle dance is a term used in beekeeping and ethology for a particular figure-eight dance of the honey bee. By performing this dance, successful foragers can share information about the direction and distance to patches of flowers yielding nectar and pollen, to water sources, or to new nest-site locations with other members of the colony.
The dwarf honey bee, Apis florea, is one of two species of small, wild honey bees of southern and southeastern Asia. It has a much wider distribution than its sister species, Apis andreniformis. First identified in the late 18th century, Apis florea is unique for its morphology, foraging behavior and defensive mechanisms like making a piping noise. Apis florea have open nests and small colonies, which makes them more susceptible to predation than cavity nesters with large numbers of defensive workers. These honey bees are important pollinators and therefore commodified in countries like Cambodia.
A bee sting is the wound and pain caused by the stinger of a female bee puncturing skin. Bee stings differ from insect bites, with the venom of stinging insects having considerable chemical variation. The reaction of a person to a bee sting may vary according to the bee species. While bee stinger venom is slightly acidic and causes only mild pain in most people, allergic reactions may occur in people with allergies to venom components.
Haplodiploidy is a sex-determination system in which males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid. Haplodiploidy is sometimes called arrhenotoky.
Apis dorsata, the rock bee or giant honey bee, is a honey bee of South and Southeast Asia. They are typically around 17–20 mm (0.7–0.8 in) long and nests are mainly built in exposed places far off the ground, like on tree limbs, under cliff overhangs, and under buildings. These social bees are known for their aggressive defense strategies and vicious behavior when disturbed. Though not domesticated, indigenous peoples have traditionally used this species as a source of honey and beeswax, a practice known as honey hunting.
A bee smoker is a device used in beekeeping to calm honey bees. It is designed to generate smoke from the smoldering of various fuels, hence the name. It is commonly designed as a stainless steel cylinder with a lid that narrows to a small gap. The base of the cylinder has another small opening that is adjacent to a bellow nozzle. Pumping of the bellows forces air through the bottom opening. The cylinder may also have a wire frame around to protect hands from burning. Some smokers have a hook on the side allowing the user to hang the device on the side of a beehive for easy access during an inspection or attach it to an ALICE belt when not in use.
A tremble dance is a dance performed by forager honey bees of the species Apis mellifera to recruit more receiver honey bees to collect nectar from the workers.
The western honey bee or European honey bee is the most common of the 7–12 species of honey bees worldwide. The genus name Apis is Latin for 'bee', and mellifera is the Latin for 'honey-bearing' or 'honey-carrying', referring to the species' production of honey.
Apis cerana, the eastern honey bee, Asiatic honey bee or Asian honey bee, is a species of honey bee native to South, Southeast and East Asia. This species is the sister species of Apis koschevnikovi and both are in the same subgenus as the western (European) honey bee, Apis mellifera. A. cerana is known to live sympatrically along with Apis koschevnikovi within the same geographic location. Apis cerana colonies are known for building nests consisting of multiple combs in cavities containing a small entrance, presumably for defense against invasion by individuals of another nest. The diet of this honey bee species consists mostly of pollen and nectar, or honey. Moreover, Apis cerana is known for its highly social behavior, reflective of its classification as a type of honey bee.
Microplitis croceipes is a braconid wasp native to the US state of Georgia. It is an important parasitoid of caterpillars, including those of major agricultural pests Helicoverpa zea and Heliothis virescens.
Bumblebees, like the honeybee collect nectar and pollen from flowers and store them for food. Many individuals must be recruited to forage for food to provide for the hive. Some bee species have highly developed ways of communicating with each other about the location and quality of food resources ranging from physical to chemical displays.
Inscentinel was a British firm based at Rothamsted Experimental Station in Hertfordshire. They specialise in the development of insect olfaction technologies for the detection of trace chemicals, specifically Hymenoptera training techniques and technologies.
Mutilla europaea, the large velvet ant, is a species of parasitoid wasps belonging to the family Mutillidae. It is a parasitoid on various species of bumblebees and is found in Europe, Asia, and North Africa.
Trigona corvina is a species of stingless bee that lives primarily in Central and South America. In Panama, they are sometimes known as zagañas. They live in protective nests high in the trees, but they can be extremely aggressive and territorial over their resources. They use their pheromones to protect their food sources and to signal their location to nest mates. This black stingless bees of the tribe Meliponini can be parasitic toward citrus trees but also helpful for crop pollination.
