What is it about?

Our noses are developed to smell feeling-related chemicals (fear, joy, sexual arousal) of other people, and therefore, we, like other creatures, ‘talk’ to each other through chemical signals. Here, we provide a comprehensive overview on olfactory communication of flies via sex pheromones to attract a mating partner, the architecture of the insect olfactory system, and the transformation of the sex pheromone signal into an electrical signal to elicit sexual behaviors.

Why is it important?

When choosing a partner, we easily discriminate between ourselves and members of other species through various communication systems. On the contrary, many fly species are morphologically similar and overlap in their geographical distributions and ecological habitats. In our review, we We shed light onto sex pheromone communication systems, the construction of olfactory nervous systems, and the role of host specialization in reproductive isolation.


We were not allowed to go to lab due to Covid restrictions, so we decided to write this review. It is very special as it is our lockdown baby!
