Among the pure stereoisomers of 5,9-dimethylheptadecane, a previously identified sex pheromone component of Leucoptera scitella L., only the S,S isomer yielded trap captures in the field. The addition of the other stereoisomers had no effect on cathes. The addition of low percentages of racemic 5,9-dimethylhexadecane, a previously identified minor component in the sex pheromone, did not influence trap catches or alter behavior of males approaching an attractant source in the field.
