Neurobiology of the gustatory systems of Drosophila and some terrestrial insects.

Insects have been favorites for the study of taste perception in the last few decades. They have been used for anatomical, behavioral, developmental, genetic, and physiological studies related to gustation and feeding response. Several genes known to affect the formation of gustatory sensilla or alter the feeding behavior of insects such as Drosophila are known. Studies related to signal transduction, coding of gustatory information, and the nature and constitution of genes involved in taste perception have also been taken up with insects in recent years. The understanding of basic mechanisms of taste perception in insects is likely to lead to better management of useful as well as harmful insects.
