Characterization and Genetic Analysis of Drosophila Melanogaster Photobehavior During Larval Development

In Drosophila melanogaster, during the mid third instar of development larvae cease foraging and commence a period of increased locomotor activity referred to as wandering behavior. In this study, we quantified the wild type larval response to light during the foraging (first, second, and early third instars) and wandering (late third instar) stages of development. Foraging larvae in the first, second and early third instars exhibited a robust …
