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. -

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. -
An Abstract of the Thesis Of
AN ABSTRACT OF THE THESIS OF Sarah A. Maxfield-Taylor for the degree of Master of Science in Entomology presented on March 26, 2014. Title: Natural Enemies of Native Bumble Bees (Hymenoptera: Apidae) in Western Oregon Abstract approved: _____________________________________________ Sujaya U. Rao Bumble bees (Hymenoptera: Apidae) are important native pollinators in wild and agricultural systems, and are one of the few groups of native bees commercially bred for use in the pollination of a range of crops. In recent years, declines in bumble bees have been reported globally. One factor implicated in these declines, believed to affect bumble bee colonies in the wild and during rearing, is natural enemies. A diversity of fungi, protozoa, nematodes, and parasitoids has been reported to affect bumble bees, to varying extents, in different parts of the world. In contrast to reports of decline elsewhere, bumble bees have been thriving in Oregon on the West Coast of the U.S.A.. In particular, the agriculturally rich Willamette Valley in the western part of the state appears to be fostering several species. Little is known, however, about the natural enemies of bumble bees in this region. The objectives of this thesis were to: (1) identify pathogens and parasites in (a) bumble bees from the wild, and (b) bumble bees reared in captivity and (2) examine the effects of disease on bee hosts. Bumble bee queens and workers were collected from diverse locations in the Willamette Valley, in spring and summer. Bombus mixtus, Bombus nevadensis, and Bombus vosnesenskii collected from the wild were dissected and examined for pathogens and parasites, and these organisms were identified using morphological and molecular characteristics. -

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.

The Zombie Fly – a Real Threat
The Zombie Fly – A Real Threat The Zombie Fly, Apocephalus borealis, is responsible for the deaths of large numbers of honeybees. The fly was only discovered to attack honeybees in 2008, so there is very little knowledge about its implications right now, including how widespread the parasitations from them are. That's where you come in! The zombie fly was first found infecting honeybees in San Francisco and now their area has determined that over 70% of their worker bees are infected by the Zombie Fly. According to an article from Scientific American: “Bees from affected hives—and the parasitizing flies and their larvae—curiously also contained genetic traces of Nosema ceranae, another parasite, as well as a virus that leads to deformed wings—which had already been implicated in colony collapse disorder. This double infection suggests that the flies might even be spreading these additional hive-weakening factors.” SFSU has created www.ZomBeeWatch.org to help determine the exact spread and depth of this issue and what role, if any, the zombie fly may be playing in Colony Collapse Disorder. YOU can help them. See reverse side for more information on how. ZomBee Watch is looking for citizen scientists to test for infections in their area and to report the results back to them. The JP2 Rockslides, an FLL robotics team from Minnesota studying human-animal relationships, are helping beekeepers and all citizens with this testing. In partnership with SFSU and Dr Hafernik, the Rockslides have created test kits to make testing easier and more affordable, and are trying to get these kits out to as many testers as possible FOR FREE! The test kits include the basics you need for testing including the light trap, tweezers, and instructions. -

Little is known about the ecology of this interaction, including phorid fecundity on bee hosts, whether phorid-bee parasitism is density dependent, and which local habitat and landscape features may correlate with changes in parasitism rates for either bumble or honey bees. We examined the impact of local and landscape drivers and host abundance on phorid parasitism of A. mellifera and the bumble bee Bombus vosnesenskii Radoszkowski (Hymenoptera: Apidae). We worked in 19 urban gardens along the North-Central Coast of California, where phorid parasitism of honey bees was first reported in 2012. We collected and incubated bees for phorid emergence, and surveyed local vegetation, ground cover, and floral characteristics as well as land cover types surrounding gardens. We found that phorid parasitism was higher on bumble bees than on honey bees, and phorids produced nearly twice as many pupae on individual bumble bee hosts than on honey bee hosts.
