Host recognition in a pollen-specialist bee: evidence for a genetic basis

  title={Host recognition in a pollen-specialist bee: evidence for a genetic basis},
  author={Christophe J. Praz and Andreas Mueller and Silvia Dorn},
To investigate the effect of larval pollen diet on floral choice in a specialized bee species, we compared the floral preferences of individuals of Heriades truncorum (Megachilidae) reared on host pollen with those of individuals reared on two different types of non-host pollen. Females were allowed to nest in cages where both host and non-host flowers were available. All females, regardless of larval diet, restricted pollen collection to their host, although they visited the flowers of both… CONTINUE READING
