摘　　要：When collecting a flower,bumblebees learn to associate floral features with reward,preferring,and specializing in the most profitable ones they visit(Chittka et al.1999).The proboscis extension reflex(PER)occurs naturally in the feeding context allowing individuals to access the floral nectaries.Under controlled conditions,the PER paradigm is a well-established controlled learning procedure used in honeybees(Takeda 1961),and some bumblebees of the genus Bombus(Laloi et al.1999).The assessment of cognitive capacities in an operant context has been studied mainly in B.terrestris and B.impatiens(Chittka 1998;Mirwan and Kevan 2014).However,little is known about the ability to evoke associative memories in an operant context,which had been acquired in a classical one.In turn,on the contrary,the Bombus genus also has the capacity to form longterm memories(Chittka 1998;McAulay et al.2015).In particular,the South American bumblebee B.pauloensis(sin.B.atratus)can learn a pure odor when it is presented in a paired association with a sugar reward within a PER paradigm(Palottini et al.2018).As other species,this one is a commercially reared pollinator that is increasingly managed in pollination services of some South American countries and they could be important for increasing production of crops(Palottini et al.2018).
