... honeybees. Bees fed with thiamethoxam could not perform differential learning and could not distinguish odours during short- and long-term memory tests. Our data indicate that thiamethoxam directly impacts the cognitive processes involved in working memory required during differential olfactory learning...

.... How these abilities are shared among the different castes and the long-term persistence of memory are now being elucidated in diverse systems, work that should shed light on general principles underlying cognitive evolution. Here, we provide the first evidence of olfactory learning and long-term...

.../methylated promoter revealed that C-fos expression is possibly controlled by odour-mediated regulation of PP-1. These results in turn imply that the differential expression of C-fos in the hippocampus and amygdala may contribute to olfactory learning and memory in C. sphinx . * Author for correspondence...

... joint exposure to field-realistic concentrations of the neonicotinoid imidacloprid and glyphosate on gustatory perception and olfactory learning. Both pesticides reduced sucrose responsiveness and had a negative effect on olfactory learning. Glyphosate also reduced food uptake during rearing...

... the odor stimulus. Proboscis extension response Differential conditioning Olfactory learning Trackball locomotion recording Learned odors influence the behavior of bees. For example, bees that were trained to associate an odor at a particular concentration with a sugar reward oriented...

... a mechanism for a molecular memory and has further been shown to play an essential role in structural synaptic plasticity. Using a combination of knockdown by RNA interference and pharmacological manipulation, we disrupted the function of CaMKII during olfactory learning and memory formation. We found...

...Erica Zhang; James C. Nieh ABSTRACT Neonicotinoid insecticides can impair bee learning and memory – cognitive features that play a key role in colony fitness because they facilitate foraging. For example, the commonly used neonicotinoid imidacloprid reduces honey bee olfactory learning. However...

...Clément Vinauger; Eleanor K. Lutz; Jeffrey A. Riffell Olfactory learning in blood-feeding insects, such as mosquitoes, could play an important role in host preference and disease transmission. However, standardised protocols allowing testing of their learning abilities are currently lacking...

... the reward pathway in olfactory learning ( Hammer, 1993 ). It has been shown that in the honeybee the MB intrinsic neurons – the KCs – alter their responses after olfactory conditioning ( Szyszka et al., 2008 ). These authors showed that although the calcium signal in response to odors decreases...

...H. T. Skiri; M. Stranden; J. C. Sandoz; R. Menzel; H. Mustaparta SUMMARY The importance of olfactory learning in host plant selection is well demonstrated in insects, including the heliothine moths. In the present study olfactory conditioning of the proboscis extension response was performed...
