The plant holobiont extends the plant’s capacity for nutrient acquisition and stress protection. Recent studies show that under biotic stress plants can promote the acquisition of certain beneficial bacteria to their rhizosphere. Active emission of v...

Evidence of Varroa -mediated deformed wing virus spillover in Hawaii (2017)
Journal Article

The spread of disease between closely related species is often times exacerbated by a vector. In this study, the Varroa mite, a pest exclusive to honeybees, has been shown to amplify the natural levels of the Deformed Wing virus, resulting in a spill...

Novel RNA virus genome discovered in Ghost ants (Tapinoma melanocephalum) from Hawaii (2017)
Journal Article

Here we report the full genome sequence of Milolii virus, a novel single stranded (positive sense) RNA virus discovered from Tapinoma melanocephalum ants in Hawaii. The genome is 10,475 nucleotides long encoding a polyprotein of 3304 amino acids.

Oldest Varroa tolerant honey bee population provides insight into the origins of the global decline of honey bees (2017)
Journal Article

The ecto-parasitic mite Varroa destructor has transformed the previously inconsequential Deformed Wing Virus (DWV) into the most important honey bee viral pathogen responsible for the death of millions of colonies worldwide. Naturally, DWV persists a... Read More about Oldest Varroa tolerant honey bee population provides insight into the origins of the global decline of honey bees.

A comparison of deformed wing virus in deformed and asymptomatic honey bees (2017)
Journal Article

Deformed wing virus (DWV) in association with Varroa destructor is currently attributed to being responsible for colony collapse in the western honey bee (Apis mellifera). The appearance of deformed individuals within an infested colony has long been... Read More about A comparison of deformed wing virus in deformed and asymptomatic honey bees.

Covert deformed wing virus infections have long-term deleterious effects on honeybee foraging and survival (2017)
Journal Article
deleterious effects on honeybee foraging and survival. Proceedings of the Royal Society B: Biological Sciences, 284(1848), 20162149. https://doi.org/10.1098/rspb.2016.2149

Several studies have suggested that covert stressors can contribute to bee colony declines. Here we
provide a novel case study and show using radio-frequency identification (RFID) tracking technology
that covert deformed wing virus (DWV) infections... Read More about Covert deformed wing virus infections have long-term deleterious effects on honeybee foraging and survival.

Moku virus : a new Iflavirus found in wasps, honey bees and Varroa (2016)
Journal Article

There is an increasing global trend of emerging infectious diseases (EIDs) affecting a wide range of species, including honey bees. The global epidemic of the single stranded RNA Deformed wing virus (DWV), driven by the spread of Varroa destructor ha...

Superinfection exclusion and the long-term survival of honey bees in Varroa-infested colonies (2015)
Journal Article
Mordecai, G. J., Brettell, L., Martin, S. J., Dixon, D., Jones, I. M., & Schroeder, D. C. (2016). Superinfection exclusion and the long-term survival of honey bees in Varroa-infested colonies. ISME Journal, 10(5), 1182-1191. https://doi.org/10.1038/ismej.2015.186

Over the past 50 years, many millions of European honey bee (Apis mellifera) colonies have died as the ectoparasitic mite, Varroa destructor, has spread around the world. Subsequent studies have indicated that the mite’s association with a group of R... Read More about Superinfection exclusion and the long-term survival of honey bees in Varroa-infested colonies.

Global honey bee viral landscape altered by a parasitic mite (2012)
Journal Article
Martin, S., Highfield, A., Brettell, L., Nikado, S., Villalobos, E., & Schoder, D. (2012). Global honey bee viral landscape altered by a parasitic mite. Science, 336(6086), 1304-1306. https://doi.org/10.1126/science.1220941

Emerging diseases are among the greatest threats to honey bees. Unfortunately, where and when
an emerging disease will appear are almost impossible to predict. The arrival of the parasitic
Varroa mite into the Hawaiian honey bee population allowed... Read More about Global honey bee viral landscape altered by a parasitic mite.

The spread and evolution of RNA viruses among honey bees and the wider insect community with particular emphasis on deformed wing virus (DWV)
Thesis
Brettell, L. (in press). The spread and evolution of RNA viruses among honey bees and the wider insect community with particular emphasis on deformed wing virus (DWV). (Thesis). University of Salford

The honey bee is our most significant animal pollinator and is highly valued economically and culturally throughout the world. Unfortunately, over the last 30 years beekeepers across the globe have experienced significantly increased honey bee colony...
