The vectoring competence of the mite Varroa destructor for Deformed wing virus of honey bees is highly dynamic and affects survival of the mite.

E. V. Ryabov, F. Posada-Florez, C. W. Rogers, Z. S. Lamas, J. D. Evans, Y. Chen, S. C. Cook

This study shows that Varroa destructor mites vector Deformed wing virus (DWV) with varying efficiency depending on their phoretic stage and the DWV type they transmit, with DWV-B reducing mite lifespan.

Pupal cannibalism by worker honey bees contributes to the spread of Deformed wing virus.

F. Posada-Florez, Z. S. Lamas, D. J. Hawthorne, Y. Chen, J. D. Evans, E. V. Ryabov

The paper shows that worker honey bees cannibalizing DWV-infected pupae transmit the virus to other bees through trophallaxis, spreading DWV without Varroa mites.

Development of a honey bee RNA virus vector based on the genome of Deformed wing virus.

E. V. Ryabov, K. Christmon, M. C. Heerman, F. Posada-Florez, R. L. Harrison, Y. P. Chen, J. D. Evans

The paper develops a honey bee RNA virus vector using Deformed wing virus (DWV) by inserting eGFP and observes genome deletions in the progeny.

Aberrant cocoons found on honey bee comb cells are found to be Osmia cornifrons (Radoszkowski) (Hymenoptera Megachilidae)

F. Posada-Florez, B. Bloetscher, D. Lopez, M. Pava-Ripoll, C. Rogers, J. D. Evans

The paper identifies Osmia cornifrons cocoons in honey bee cells, suggesting they use honey bee resources and may benefit from bee provisioning, potentially offering a method for mass-producing pollinators.

A novel system for maintaining Varroa destructor mites on artificial diets and its application for studying mites as a vector for honey bee viruses.

F. Posada-Florez, E. V. Ryabov, M. C. Heerman, Y. Chen, J. D. Evans, S. C. Cook, D. E. Sonenshine

This paper introduces a novel in vitro system to maintain Varroa destructor mites on artificial diets and demonstrates their ability to acquire and transmit honey bee viruses.

Dynamic evolution in the key honey bee pathogen Deformed wing virus

E. V. Ryabov, A. K. Childers, D. Lopez, K. Grubbs, F. Posada-Florez, D. Weaver, W. Girten, D. vanEngelsdorp, Y. Chen, J. D. Evans

This study investigates the population dynamics of Deformed wing virus (DWV) in honey bees, finding high genetic diversity in US colonies and proposing a model of diversification driven by negative frequency-dependent selection.

PLOS Biology · Oct 10, 2019Peer-reviewedMicrobiology

Deformed wing virus type A, a major honey bee pathogen, is vectored by the mite Varroa destructor in a non-propagative manner.

F. Posada-Florez, A. K. Childers, M. C. Heerman, N. I. Egekwu, S. C. Cook, Y. P. Chen, J. D. Evans, E. V. Ryabov

This study shows that Deformed wing virus type A is transmitted by Varroa mites without replication in the mites, as viral load decreases after passage and negative-strand RNA is only detected in mites exposed to high viral loads.
