Virus and mite wiping out millions of bees worldwide: study

The video explains the presence of the deformed wing virus in bees, which is generally benign, affecting about 10% of the population. However, the introduction of the varroa mite changes this dynamic. The mite feeds on the bees' blood, leading to the disappearance of innocuous viruses and the proliferation of a lethal strain of the deformed wing virus. As a result, the frequency of the virus in bee colonies increases dramatically from 10% to 100%.

What percentage of bees are initially affected by the deformed wing virus without any threat to the colony?

• 50%

• 10%

• 5%

• 100%

How does the varroa mite affect the deformed wing virus in bees?

• It reduces the virus's impact.

• It has no effect on the virus.

• It increases the virus's lethality.

• It eliminates the virus completely.

What happens to the harmless viruses in bees when infested by varroa mites?

• They disappear over time.

• They multiply rapidly.

• They remain unchanged.

• They become more harmful.

What is the primary way varroa mites feed on bees?

• By consuming bee nectar.

• By feeding on bee blood.

• By eating bee pollen.

• By absorbing bee honey.

What is the effect of varroa mite infestation on the frequency of the deformed wing virus in bees?

• It decreases from 10% to 5%.

• It remains at 10%.

• It fluctuates between 10% and 50%.

• It increases from 10% to 100%.
