Canadian scientists have discovered that the elimination of pheromones made the fruit flies attractive to one another regardless of sex.

The University of Toronto’s scientists have discovered that genetically altered fruit flies failed to produce a special sort of pheromone or odor, which turned them sexually irresistible to both males as well as females.

Speaking on the topic, Professor Joel Levine said, “That means the same chemical signals and genes are underlying not only social behavior in groups, like courtship and mating, but also behavior between species.”

Professor Levine further added that though pheromones play a vital role in human mating, yet human system is much more complex than that of fruit flies. 

The researchers said that even flies of a different species were attractive to after the pheromone was eliminated.

The study, which was looking at how fruit flies recognize sex, was published in the science journal, Nature.
