The animals, in particular insects (Drosophila melanogaster), response towards odor stimuli in nature can be established by measuring the dynamic of the odor response. Such an approach is innovative since responses to odors were tested only at certain time point so far, not in hour intervals for several hours. The odor attraction to 14 natural and ecologically relevant odor stimuli such as fruits- ripe and rotten, yeast and vinegar was tested. A mathematical model to evaluate obtained data is proposed in this study in which the number of flies caught over several time points is presented as one simple parameter showing trapping potential of the trap housing particular odor stimuli. The knowledge concerning dynamic of the odor response in Drosophila melanogaster may enlighten the principles of flies behavior in context of exposure towards odor stimulus.
