Pyrethroid pesticides are highly toxic to bees. But are the bees’ perception, memory, and learning centers affected by sublethal doses of these substances?Using a battery of cognitive tests, researchers were able to show that habituation and olfactory learning are indeed affected.

What are the properties of gene regulation in genes whose expression is sensitive to environmental factors (plastic genes), as opposed to genes whose expression is independent of the environment (non-plastic genes)?
