Parasitic Phorid Fly Emerging Threat to Honey Bees
A detailed examination of bees from infected hives also often revealed the presence of two other known bee pathogens, deformed wing virus, and a single-celled parasite, Nosema ceranae, itself implicated in Nosema apis, a widespread disease of honeybees. Both adult and larval phorids also tested positive for the presence of these pathogens, implicating the fly as vector.
Scientists found 77% of sampled colonies in the San Francisco Bay Area to be infected by the fly, and there were additional surveys turning up the parasites in both South Dakota and California's Central Valley. Read the study HERE.
Update - February 2014: So-called zombie bees have now been found in Washington, Oregon, South Dakota, and Vermont .

|Honeybees probably originated in Tropical Africa and spread from South Africa to Northern Europe and East into India and China. The first bees appear in the fossil record in deposits dating about 40 million years ago during the Eocene period. At about 30 million years before present they appear to have developed social behavior and structurally are virtually identical with modern bees. |
Apis mellifera, the most commonly domesticated species, is native to Europe, Asia and Africa. There are many sub-species that have adapted to the environment of their geographic and climatic area. Behavior, color and anatomy can be quite different from one sub-species to another. The sub-species Apis mellifera mellifera was brought to the Americas with the first colonists to Virginia in 1622, and numerous other occasions later. Many of the crops that depend on honeybees for pollination have also been imported since colonial times. Escaped swarms spread rapidly as far as the Great Plains, usually preceding the colonists. The Native Americans called the honeybee "the white man's fly." Honeybees did not naturally cross the Rockies; they were carried by ship to California in the early 1850s.
Honey has been used by humans for thousands of years for its health benefits and as a sweetener and flavoring for many foods and beverages with tea being the most popular. However, if it is to be used for its health-benefits, it must be raw honey since heating honey (pasteurization) destroys the all of the pollen, enzymes, propolis, vitamins, amino acids, antioxidants and aromatics.
The next three to six days are spent feeding pollen and honey to the larvae. Both of these foods are stored, separated, in different groups of cells throughout the hive. From about the seventh day, for about a week, the honeybee develops two large glands in its head which secrete royal jelly, a vital growth-promoting substance. This protein-laden fluid is exuded from the bee's mouth and is fed to the queen and very young larvae. The queen is fed royal jelly continuously throughout her life; she ripens and deposits about 100 eggs every hour of the day and night. This astounding feat obviously requires vast amounts of metabolic fuel and building materials, and the royal jelly packs an enormous amount of energy.
The bees in a normal colony have perhaps 10,000 larvae to feed at any one time, and each of these may require several thousand feeding visits in the six days they take to mature. A healthy colony may contain 50 to 80 thousand individuals, including 2 or 3 thousand male bees (drones). They, too, are fed with royal jelly until they are either expelled from the nest during a swarm, or are killed by stinging and thrown out . Between the 12th and 18th day of their existence, the bee's wax glands begin to produce the substance from which the combs are constructed. They are then occupied with receiving pollen and honey from the foragers, building storage and brood cells, and standing sentry duty at the hive entrance.
The third and final phase of a honeybee's life is spent in the field, gathering pollen and honey and returning it to the hive. During this period the bee also passes information to her sister foragers regarding the location of food sources, including the direction and distance from the hive. These data are communicated through a complex series of "dance" movements performed on the honeycomb. The spatial orientation of the dance is related to the sun's position, and the number of "wiggles" the bee incorporates gives the distance to and abundance of the food source. An adult honeybee survives about 10 days of foraging, for a total lifespan of about 35 days.
Honey Bee Drone Pupae with Varraoa Mites 
|Honeybees, both wild and domestic, are undergoing a worldwide decline due to infestations of parasitic mites and the ravages of various viruses, as well as susceptibility to pesticides. Bees, via pollination, are responsible for 15 to 30 percent of the food U.S. consumers eat. But in the last 50 years the domesticated honeybee population, which most farmers depend on for pollination, has declined by about 50 percent, scientists say.|
The honey bee mite, Acarapsis woodi, is a microscopic mite only detectable through dissection. They are whitish in color with oval bodies, and have a shiny cuticle with a few long fine hairs on the body and legs. They are sometimes referred to as "tracheal bee mites" or "honey bee tracheal mites." This small mite is an internal parasite of honey bees. It infests and lives entirely within the tracheal (respiratory) system of honey bees, primarily in the prothoracic section. The queens, drones, and workers are all attacked. Tracheal bee mites feed by puncturing the breathing tubes of the host with their mouthparts. They feed on blood from the host. Honey bees infested by this parasite may become unable to fly. Heavily infested bees may crawl on the floor of the hive or cluster in the hive. Life spans of bees are shortened by heavy mite infestations, which cause a condition called acarine disease or acariosis. (The mites are members of the order Parasitiformes).
The Varroa Mite is a bloodsucking parasite that attacks young and adult honeybees. Attacked bees often have deformed wings and abdomens and a shortened life span. The varroa mite is effective at transmitting disease, particularly viruses. Left untreated, a varroa mite infestation can wipe out a bee colony within a few months. Both the varroa and tracheal mites lead to the death of the bees by puncturing holes in their bodies that serve as pathways for viruses. The viruses are what technically kill most of the bees.
Honey Bees congregate at hive entrance
Hymenoptera (Latin for membrane wing) is a vast assemblage of insects second only to Coleoptera (beetles) in the number of described species. Hymenoptera number some 115,000 species - of which 18,000 live in North America. Hymenopterans inhabit a wide variety of habitats, and show an incredible diversity in size, behavior, structure and color.
