...Elisabeth Adam; Bill S. Hansson; Markus Knaden ABSTRACT Insect pollinators, such as the tobacco hawkmoth Manduca sexta , are known for locating flowers and learning floral odors by using their antennae. A recent study revealed, however, that the tobacco hawkmoth additionally possesses olfactory...

Furthermore, learning experiments showed that bumblebees are able to use differences in floral humidity to distinguish between...

Interval timing Learning Temporal conditioning Information of time in the environment is crucial to optimize physiology and behavior of organisms from amoebae to humans ( Buhusi and Meck, 2005 ; Saigusa et al., 2008 ). Insects, for example, change their behavior according to a wide range of time...

Further, when the shape and color of a target that they had been trained to identify were placed in conflict, N. oerstedii tended to choose the target of the trained shape over the target of the trained color. Thus, we conclude that the shape of the target was more...

While caffeine potentiates responses of mushroom body neurons involved in honeybee learning processes, arginine acts as precursor of nitric oxide, enhancing the protein synthesis involved in memory formation. Despite existing evidence on how these compounds affect honeybee cognitive...
