In this work, we established a new paradigm for the study of learning and memory in Drosophila melanogaster. This paradigm highlights the strategies used by flies to evade one of their natural predators, the spider Menemerus semilimbatus, in a controlled environment. The running hypothesis postulates the existence of memory processes involved in the storage of useful strategies to survive a risk of predation.
The main objective was to find the parameters that describe the behavior of flies to keep themselves alive when faced to a predator, interpreted as a learning process. And finally, to study the memory dynamics of Drosophila melanogaster, defining which parameters are descriptors of behaviors in which memory retention can be evaluated.
