Figure 4

Relationships between the proportion of individual pheromone components and the age of European corn borer Z males. The proportion of Z9-16:OAc is not correlated with age (A) (r s = -0.157, P = 0.302), neither is the proportion of Z14-16:OAc (B) (r s = -0.054, P = 0.722). The proportion of 16:OAc is negatively correlated with age (C) (r s = -0.645, P < 0.001), and the proportion of Z11-16:OAc is positively correlated with age (D) (r s = 0.721, P < 0.001). N = 45 males, 15 per age class.
