The importance of weeds as melliferous flora in central Chile

The use of native flora by Apis mellifera L. in Chile has been demonstrated in many studies; however, certain species that are viewed as weeds contribute extensively to the floral composition of honey. A total of 92 honey samples from the Libertador General Bernardo O'Higgins region in Chile we...

A total of 92 honey samples from the Libertador General Bernardo O'Higgins region in Chile were analyzed to determine which weeds are most important in honey production and which are most preferred by melliferous bees.

A total of 19 weeds were identified at the species level from the pollen types found, and five weeds were identified at the genus level. The weeds were classified as contributing very frequently, frequently, rarely and occasionally to honey using the methodology described by Louveaux et al. (1970) for determining the frequency with which plant species contribute to honey based on the corresponding pollen types found in honey. Overall, 74% of the weeds used by Apis mellifera were European, and 53% of the weeds had perennial life cycles.
