COMPARITIVE STUDIES OF VARIENT DIETS IN DROSOPHILA MELANOGASTER WITH RESPONSE TO GUSTATION AS FEEDING BEHAVIOUR

Gustatory assay and nutritional constituents is an important factor determning the feeding behaviour of an organism. In this review, feeedingbehaviour in Drosophila melanogasterpre-adult (larvae) was investigated and the results were compared with those forpost- adult (flies) stages, supplementing Drosophila with varientdietsnamely yeasts and fruits. It was obserevd that pre-adult preferred yeast supplemented diets rather than control and fruits, while the post adult showed preference choice for fruits than yeast and control. Thus,higher nutritional value of fruit and yeast with control is expected to favor sensory and physiological adaptations for feeding behaviour,showing gustatory receptors act cooperatively in larval and adult taste sensing in every stages of development having different degree of responsiveness to varient diet supplemented.
