Selection response in sex pheromone
All three acetates responded to selection for higher/lower relative total amounts of acetates in the high and low line, respectively (Fig 2). The response was more pronounced in the more abundant Z9 and Z11 isomers compared to the less abundant Z7-16:OAc (Fig 2). The selection response was characterized by an immediate response in the direction of selection (from generation 0 to generation 1), followed by a gradual progression towards increasing/decreasing relative amounts in the respective selection lines. In the low line, the selection response flattened after cessation of selection, while in the high line, the average ratio of Z11:16:OAc to 14:Ald was higher in generations 11-13 compared to generations 7-10 (Fig 2D).
