Are commercial honeybees making wild bees sick?: What they found

Question

All of the honeybee colonies tested by the researchers were positive for both viruses, an unfortunate but common occurrence for commercial colonies.

But the number of wild bumblebees carrying viruses varied depending on the proximity to the domesticated hives. There was also variation between the two viruses.

More than 90 percent of bumblebees collected close to apiaries carried black queen cell virus. In sites farther from apiaries, and where no honeybees were foraging, just under 40 percent were positive for this virus. when the researchers checked for actual infections, they found that the proximity to an apiary wasn't telling of whether a bumblebee was infected with black queen cell virus. That means sites near and far from a commercial beehive had the same abundance of black queen cell virus infections.

The connection was clearer for deformed wind virus infections. Twenty percent of bumblebees foraging close to apiaries carried the virus on their outsides and 10 percent had active infections. But in sites more than a half mile away from an apiary, where honeybees were absent, not a single bumblebee tested positive for deformed wing virus - as a carrier or with an infection.

When the researchers looked at infected flowers, they noticed a similar trend. Of the 20 percent of flowers that tested positive for viruses, all were picked close to apiaries. And the denser the flower patch in these areas, the higher the rate of deformed wing virust infection in bumblebees.

Researchers claimed they found a relationship between bumblebee infections and how close the bumblebees were to honeybee apiaries.

the percentage of bumblebees infected based on their proximity to apiaries
the percentage of bumblebees infected based on their proximity to apiaries

the fact that all the honeybee apiaries researchers tested were infected with both viruses

Answer 1

The evidence from the text that supports the analysis in the last sentence of the article excerpt is:

the percentage of bumblebees infected based on their proximity to apiaries.

This is because the findings clearly show a correlation between the location of bumblebees in relation to honeybee apiaries and the presence of viral infections, particularly with deformed wing virus, which had higher infection rates in bumblebees foraging close to apiaries compared to those further away.
