For instance, the rusty-patched bumblebee, Bombus

To assess the potential for social learning in bumblebees (Bombus
impatiens), we investigated the spread of foraging techniques from experienced bees to inexperienced bees in the same and different colonies.
Over the past three decades, a significant body of research has identified declines in bumble bee (Bombus
) faunas of several European nations (Williams, 1982; Sarospataki et al., 2005; Goulson et al., 2006; Fitzpatrick et al., 2007; Kosior et al., 2007; Williams and Osborne, 2009).
Las especies de abejorros (genero Bombus
) tienen preferencia por las hierbas perennes como recursos forrajeros (Dramstad & Fry 1995), y por lo general se asume que el comportamiento de eleccion de las abejas de colores florales se ve influenciada por las preferencias innatas antes de cualquier experiencia (Gumbert 2000).
Over the past few years, one bumble bee in particular, the western bumble bee, Bombus
occidentalis, has caught his eye.
In recent years, many bumblebee (Bombus
) species have shown sharp declines in their abundance in many parts of the globe (Rasmont, 1995; Buchmann and Nabhan, 1996; Westrich, 1996; Kevan and Phillips, 2001) especially in the last 50 years (Goulson et al., 2005).
