The present invention is directed generally to a method of identifying an insect pheromone. Initially, a candidate insect pheromone-binding protein is obtained and sequenced. Specific proteins may then be selected by observing the pattern of pheromone-binding protein expression in the insect stage, phase or caste; and/or in the antenna and other sensilla by, for example, in situ hybridization; and/or by comparison with sequence of known pheromone binding proteins. A composition of one or more pheromones may then be contacted with the pheromone-binding protein. Any pheromones bound to the protein may then be eluted and analyzed.
