Consumption of bananas appears to make a human more attractive to the Anopheles stephensi mosquito

In September 2018 researchers from the USA published the results of their study to assess human attractiveness to mosquitoes following the consumption of bananas. It is known that humans vary in attractiveness to mosquitoes which has been partly attributed to differences in odours emanating from the skin, and it is also known that diet can alter that odour. Human attractiveness to the Anopheles stephensi mosquito was measured before and 1-3 hours following the consumption of bananas and grapes. Results showed that consumption of grapes did not appear to make an individual more attractive to the mosquitoes although banana consumption did. Further tests with a single volunteer showed that the effect was repeatable and consistent across 15 trials. It was also seen that the magnitude of the increase was not affected by the number of bananas eaten.
