Save the Bees Save the Bees
Unit for week 5 save the bees Save the bees Stresses on the Honey bee Several factors may create stress in the hive, which can cause a decrease in population. Below are some of those possible contributors. All of these effects on the colony can be observed, some more easily than others, in the Observation Hive.

A Saliva Protein of Varroa Mites Contributes to the Toxicity Toward Apis Cerana and the DWV Elevation Received: 10 August 2017 Accepted: 9 February 2018 in A
www.nature.com/scientificreports OPEN A Saliva Protein of Varroa Mites Contributes to the Toxicity toward Apis cerana and the DWV Elevation Received: 10 August 2017 Accepted: 9 February 2018 in A. mellifera Published: xx xx xxxx Yi Zhang & Richou Han Varroa destructor mites express strong avoidance of the Apis cerana worker brood in the feld. The molecular mechanism for this phenomenon remains unknown. We identifed a Varroa toxic protein (VTP), which exhibited toxic activity toward A. cerana worker larvae, in the saliva of these mites, and expressed VTP in an Escherichia coli system. We further demonstrated that recombinant VTP killed A. cerana worker larvae and pupae in the absence of deformed-wing virus (DWV) but was not toxic to A. cerana worker adults and drones. The recombinant VTP was safe for A. mellifera individuals, but resulted in elevated DWV titers and the subsequent development of deformed-wing adults. RNAi- mediated suppression of vtp gene expression in the mites partially protected A. cerana larvae. We propose a modifed mechanism for Varroa mite avoidance of worker brood, due to mutual destruction stress, including the worker larvae blocking Varroa mite reproduction and Varroa mites killing worker larvae by the saliva toxin. The discovery of VTP should provide a better understanding of Varroa pathogenesis, facilitate host-parasite mechanism research and allow the development of efective methods to control these harmful mites. Varroa destructor Anderson & Trueman (Acari: Varroidae) was originally identifed as an ectoparasite of the Asian honeybee Apis cerana. Before the year 2000, V. destructor was miscalled V. jacobsoni. In fact, these two species are diferent in body shape, cytochrome oxidase (CO-I) gene sequence, and virulence to honey bees1. -

INTRODUCTION Honey bees weren’t on veterinarians’ radars until the U.S. Food and Drug Administration issued a final Veterinary Feed Directive (VFD) rule, effective January 1, 2017, that classifies honey bees as livestock and places them under the provisions of the VFD. As a result of that rule and changes in the FDA’s policy on medically important antimicrobials, honey bees now fall into the veterinarians’ purview, and veterinarians need to know about their care. -
Effect of Wood Preservative Treatment of Beehives on Honey Bees Ad Hive Products
1176 J. Agric. Food Chem. 1984. 32, 1176-1180 Effect of Wood Preservative Treatment of Beehives on Honey Bees and Hive Products Martins A. Kalnins* and Benjamin F. Detroy Effects of wood preservatives on the microenvironment in treated beehives were assessed by measuring performance of honey bee (Apis mellifera L.) colonies and levels of preservative residues in bees, honey, and beeswax. Five hives were used for each preservative treatment: copper naphthenate, copper 8-quinolinolate, pentachlorophenol (PCP), chromated copper arsenate (CCA), acid copper chromate (ACC), tributyltin oxide (TBTO), Forest Products Laboratory water repellent, and no treatment (control). Honey, beeswax, and honey bees were sampled periodically during two successive summers. Elevated levels of PCP and tin were found in bees and beeswax from hives treated with those preservatives. A detectable rise in copper content of honey was found in samples from hives treated with copper na- phthenate. CCA treatment resulted in an increased arsenic content of bees from those hives. CCA, TBTO, and PCP treatments of beehives were associated with winter losses of colonies. Each year in the United States, about 4.1 million colo- honey.

Colony Collapse Disorder in Relation to Human-Produced Toxins: What's
Colony Collapse Disorder in relation to human-produced toxins: What’s the buzz all about? Available at: http://www.sawyoo.com/postpic/2013/09/honey-bee-hives_77452.jpg Last accessed: 17/04/2017 Abstract: p2 Introduction: p3 Insecticides: p5 Herbicides & fungicides: p7 Miticides & other preventative measures: p9 “Inactive” ingredients: p10 Synergies between pesticides: p11 Conclusions: p12 Discussion: p12 References: p14 1 Abstract In recent years, the global population of pollinating animals has been in decline. The honey bee in particular is one of the most important and well known pollinators and is no exception.The Western honey bee Apis mellifera, the most globally spread honey bee species suffers from one problem in particular. Colony Collapse Disorder (CCD), which causes the almost all the worker bees to abandon a seemingly healthy and food rich hive during the winter. One possible explanation for this disorder is that it is because of the several human produced toxins, such as insecticides, herbicides, fungicides and miticides. So the main question is: Are human-produced toxins the primary cause of CCD? It seems that insecticides and, in particular, neonicotinoid insecticides caused increased mortality and even recreated CCD-like symptoms by feeding the bees with neonicotinoids. Herbicides seem relatively safe for bees, though they do indirectly reduce the pollen diversity, which can cause the hive to suffer from malnutrition. Fungicides are more dangerous, causing several sublethal effects, including a reduced immune response and changing the bacterial gut community. The levels of one fungicide in particular, chlorothalonil, tends to be high in hives. Miticides levels tend to be high in treated hives and can cause result in bees having a reduced lifespan. -

Honey Bee from Wikipedia, the Free Encyclopedia
Honey bee From Wikipedia, the free encyclopedia A honey bee (or honeybee) is any member of the genus Apis, primarily distinguished by the production and storage of honey and the Honey bees construction of perennial, colonial nests from wax. Currently, only seven Temporal range: Oligocene–Recent species of honey bee are recognized, with a total of 44 subspecies,[1] PreЄ Є O S D C P T J K Pg N though historically six to eleven species are recognized. The best known honey bee is the Western honey bee which has been domesticated for honey production and crop pollination. Honey bees represent only a small fraction of the roughly 20,000 known species of bees.[2] Some other types of related bees produce and store honey, including the stingless honey bees, but only members of the genus Apis are true honey bees. The study of bees, which includes the study of honey bees, is known as melittology.

Small Hive Beetle a Serious New Threat to European Apiculture
68639_CENTSCILAB 6/4/03 20:48 Page 1 The Small Hive Beetle A serious new threat to European apiculture About this leaflet This leaflet describes the Small Hive Beetle (Aethina tumida), a potential new threat to UK beekeeping. This beetle, indigenous to Africa, has recently spread to the USA and Australia where it has proved to be a devastating pest of European honey bees. There is a serious risk of its accidental introduction into the UK. All beekeepers should now be aware of the fundamental details of the beetle’s lifecycle and how it can be recognised and controlled. 68639_CENTSCILAB 6/4/03 20:49 Page 2 Introduction: the small hive beetle problem The Small Hive Beetle, Aethina tumida It is not known how the beetle reached either (Murray) (commonly referred to as the 'SHB'), the USA or Australia, although in the USA is a major threat to the long-term shipping is considered the most likely route. sustainability and economic prosperity of UK By the time the beetle was detected in both beekeeping and, as a consequence, to countries it was already well established. agriculture and the environment through disruption to pollination services, the value of The potential implications for European which is estimated at up to £200 million apiculture are enormous, as we must now annually. assume that the SHB could spread to Europe and that it is likely to prove as harmful here The beetle is indigenous to Africa, where it is as in Australia and the USA. considered a minor pest of honey bees, and until recently was thought to be restricted to Package bees and honey bee colonies are that continent.
