We recently isolated 9 cultivable bacteria from the reproductive organs of B. dorsalis. Using 4-armed olfactometer, the isolated bacteria were provided to B. dorsalis as odor source. Out of the 9 bacteria, 1 bacteria attracted males, significantly (P < 0.0001). Is there a possibility of a bacterium acting as a mediator of "Sex" in insects. Can it be a symbiotic host-microbe interaction?
