Honey Bee. Australia's early European settlers introduced Honey Bees to ensure a good supply of honey.
Identification Honey Bees are one of the most recognisable insects and are the most commonly domesticated bee species in the world. Biosecurity Act 2015. The role of fat bodies in bee health - Honey Bee Suite. All insects have fat bodies—tissues that contain lipids, glycogen, triglycerides, and some protein.
Fat bodies store energy when food is plentiful and release energy when the bee needs it. The energy stored within these tissues is especially important during larval growth. It is also important during other periods when feeding is restricted, such as during the winter months. The metabolic action of fat bodies is often compared to the vertebrate liver because they store nutrients and synthesize proteins, lipids, and carbohydrates that circulate throughout the body. Scientists modify honey bee gut bacterium to fight colony collapse-causing Varroa mite and deformed-wing virus - Science News - ABC News. Colony Collapse Disorder caused the loss of an estimated 40 per cent of honey bee colonies in the US last year — the worst winter decline on record for tracked hives since research began.
Now researchers have genetically engineered a bacterium that lives in the gut of honey bees, to boost their ability to fight off pathogens that are often responsible for colony collapse.

These mites can ruin the entire bee colony if left untreated that’s why there is an array of methods that can be done to control and even completely remove these unwanted arachnids. Physical, behavioral, and mechanical methods can control Varroa mite population while chemical measures can eradicate them completely.

Genetically Engineered Bacteria Protect Honey Bees Against Parasites. In a new study published in the journal Science, researchers from The University of Texas at Austin outline their novel approach to protecting honey bees at risk of colony collapse – genetically engineered bacteria.
What is colony collapse? A busy bee behind the lens – News. This month’s Australian Geographic features a cover photo of a Blue-banded Bee (Amegilla cingulata) by Flinders Biological Sciences Honours student James Dorey.
They’re small and furry with a sting in their tail but look truly magnificent enlarged by a camera. So much so, dramatic native bee photos by Flinders BSc (Hons) student James Dorey have made the front cover story of the latest Australian Geographic. Over several years, the keen naturalist has perfected the art of using his camera skills to home in on the tiny and unseen, in particular native bees. His impressive ability to capture all creatures great and small on his 100mm macro lens has opened up a new world to a growing audience.
One of his impressive photos – a detailed, close-up action pic of a native bee in flight (see main image) appears as the main picture feature of the latest edition of Australian Geographic. “I’m driven by my love of nature.

National Bee Biosecurity Program « Bee Aware. Home > National Bee Biosecurity Program The National Bee Biosecurity Program has been developed to help beekeepers manage the health of their hives.
The role of Bee Biosecurity Officers is to help beekeepers, making sure they understand how to prevent the spread of pests and diseases within their hives. New South Wales. SAcommunity - Connecting Up Australia. Dr Katja Hogendoorn. Methods to Control Varroa Mites: An Integrated Pest Management Approach. These ectoparasitic mites arrived in the U.S. in 1987 and spread throughout the world after they jumped from the Asian honey bee (Apis cerana) to the European honey bee.
Varroa mites reproduce in cells with developing workers and drones (Figure 2). Drone brood cells are larger and the post-capping stage is longer (15 days for drones versus 11 days for workers), which allows the mite to produce more offspring per cycle. Varroa mites do not reproduce within queen cells because of the repellency of royal jelly and the very short post-capping period of queens (7 days). Varroa destructor. Varroa destructor (Varroa mite) is an external parasitic mite that attack and feeds on the honey bees Apis cerana and Apis mellifera.
The disease caused by the mites is called varroosis. The Varroa mite can only reproduce in a honey bee colony. It attaches to the body of the bee and weakens the bee by sucking fat bodies.[1] The species is a vector for at least five debilitating bee viruses,[2] including RNA viruses such as the deformed wing virus (DWV). Varroa jacobsoni. Varroa jacobsoni is a species of mite that parasitises Apis cerana (Asian honey bees). The more damaging Varroa destructor was previously included under the name V. jacobsoni, but the two species can be separated on the basis of the DNA sequence of the cytochrome oxidase I gene in the mitochondrial DNA.[3] Biogeography[edit] Prior to recent studies, V. jacobsoni was considered homogeneous; however, current research has detected genetic variance among populations by using genetic markers.[4][5] This finding has led to the belief that V. jacobsoni was introduced to the Americas multiple times.
The hosts switching between the eastern A. cerana and the western A. mellifera is the major factor that broadens the pathological transmission of V. jacobsoni.[6] It has spread worldwide with the exception of Australia [7] and central Africa. Evolution[edit] Varroa mites « Bee Aware. Life cycleEffectDetectionSpread & distributionOverseas experiencesResponseAdditional informationVideos Life cycle Different life stages of Varroa mites at the bottom of a brood cell. CSIRO Varroa mites are parasitic mites, which require a honey bee host to survive and reproduce. Department of Agriculture and Fisheries, Queensland. Have genetic holes in their armor. Seemingly indestructible Varroa mites have decimated honeybee populations and are a primary cause of colony collapse disorder, or CCD. Michigan State University scientists have found genetic holes in the pests' armor that could potentially reduce or eliminate the marauding invaders.
The team's results, published in the current issue of Insect Science, have identified four genes critical for survival and two that directly affect reproduction. "The Varroa mite is the worst threat to honeybee health worldwide," said Zachary Huang, MSU entomologist. "They have developed resistance to many pesticides, so it's urgent that we explore and target these genes to develop better control methods. " U.S. honeybees had the worst winter die-off in more than a decade. Breeders toughen up bees to resist deadly mites.
The death of his favorite queens in 2013 was the final straw for BartJan Fernhout, an amateur beekeeper in Boxmeer, the Netherlands. Fernhout's queens, which he had purchased from a specialty breeder, produced workers with prized traits: They were calm and made plenty of honey. Then, Fernhout's hives became infested with a parasitic mite named Varroa destructor, which has become a major contributor to the demise of bee colonies worldwide. Fact sheet - Varroa (jacobsoni) mite (326) Honey bee biosecurity arrangements. The threat of varroa mite is real. But these Australian beekeepers are ready to face it.

The Bees in Decline. Why Are Honeybees Dying Off? A: We’re pretty certain that bees are not dying from GMOs, cellphones, ultraviolet lights, electromagnetic radiation, or aliens, all of which have been blamed at one point or another. There is no single cause, according to most scientists who have studied the problem, but rather a combination of factors that include parasites, pathogens, pesticides, poor nutrition, and habitat loss.
