Gustatory stimuli, such as sugar, induce a behavioral response in Drosophila that involves extension of the proboscis and consumption of the sugar-containing solution. Addition of salt to the sugar solution inhibits this behavioral response. However, the mechanisms and gene products involved in the salt aversion response have not been described. Here, we(More)
The development of wings has undoubtedly played a major role in the enormous diversification of insects. New insights into the evolutionary history of insect wings are available from paleontological, physiological and biomechanical studies. A recent hypothesis, derived primarily from paleontological evidence, is that wings arose from leg exites, small flaps(More)
Workers in a social insect colony have distinct experiences that may affect their performance in a learning task. In this study using free-foraging and flight-cage bumblebee Bombus huntii colonies, the strength of olfactory proboscis extension conditioning (PEC) was affected by a bee’s task specialization as a nurse or forager and the stimulus odor. Nurses(More)
