Viruses in beehives and why it is important to explore them

What factors influence the spread of viruses through wild bee communities?

Vocabulary and sources

Additional research and information about viruses in bee communities

About the project

- founded by Galen Cobb (PhD candidate)

- viral diseases and other pathogens are one of the top four threats to bees

- aim: identify prensence and susceptibility of viruses in bee communities

- collect 200 bees from up to 20 species and test each for the presence of four common bee viruses:

*) black queen cell virus

*) deformed wing virus

*) Israeli acute paralysis virus

*) sacbrood virus

- assess prediction of viral infections

within bee communities

Black queen cell virus

Israeli acute paralysis virus

Bee viruses represent 8% of the total bee mortality

Useful phrases

  • sudden vastly decrease in the numbers of worker honey bees
  • pathogens/parasites (varroa mites), pesticides, malnutrition, environmental stress, low genetic diversity, and migratory beekeeping practices
  • Causes mortality in queen bee pupae, with dead queen bee larvae turning yellow and then brown-black
  • Nosema apis, a microsporidian parasite of honey bees that invades the gut of adult honey bees

colony collapse disorder - special form of death of bees

pathogen spillover - pathogens transmit from one host species

to another

susceptibility - lack of ability to resist a pathogen or drug

to wreak havoc - to cause great damage

vastly - substatially

Viruses, bacteria 8%

Deformed wing virus

Sacbrood virus

  • Transmitted by the ectoparasitic mite varroa destructor
  • These deformities are symptomatic of the final stages of colony collapse
  • Causes an uneven brood pattern with discoloured, sunken or perforated cappings
  • Larvae infection by consuming √contaminated brood food
  • Larvae sit in the cell with their heads raised, die shortly after capping
  • The skin of the larvae then gradually becomes a fluid filled sac
