Research project

Colour preferences of stingless bees

Flower choice in bees mainly depends on olfactory and visual cues. Especially species like the Western honeybee (Apis mellifera) or the Buff-tailed bumblebee (Bombus terrestris), which contribute to crop pollination, are studied so far (e.g. Lunau 1990; Lunau and Maier 1995; Lunau et al.1996). Many stingless bees (Meliponini) of the tropics and Australia that are ecologically and agriculturally important are highly understudied.

My research focuses on colour preferences of stingless bees with special regard to the colour parameters dominant wavelength (= hue), colour intensity (= brightness) and spectral purity (= saturation). The experiments take place in natural habitats of stingless bees in Sao Paulo, Brazil, and Melbourne, Australia, in cooperation with Isabel Alves-dos-Santos and Adrian Dyer respectively. Our aim is to analyse innate and learned colour preferences and compare these to findings regarding more frequently studied species like A. mellifera and B. terrestris. These results shall help us understanding the flower choice and foraging strategies of stingless bees.
