Nectar Sugar Enhancement in Response to Bee Buzzing in Rhododendron x pulchrum: Sound-sensing Organs and Sensitivity Range

Kokomi Seike, Atsushi Tani, Gaku S. Hirayama, Atushi Ushimaru

This study shows that Rhododendron x pulchrum and Lamium amplexicaule increase nectar sugar concentration in response to bee buzzing sounds, with a sensitivity threshold and involvement of petals and stamens in sound sensing.
