It was news to me! With no scientific background to speak of, I’d never heard the word `pheromones’ before and the introduction I had to Professor Neelakanthi Ekanayake-Gunawardena from my son who had met her in Australia, mentioned only that she had carried out some interesting research into chemical signals given out by insects. Unprepared as I was for the “unprofessor-like” appearance of the youthful, sweet-faced woman who greeted me I was fascinated by her explanation of the phenomenon of `pheromones’ . |
