Figure 5 From: Concerted evolution of male and female display traits in the European corn borer, Ostrinia nubilalis Composition of male pheromone in corn borers. (A) Partial gas chromatograms of hairpencil extracts from virgin 4-day-old ECB Z, ECB E and Asian corn borer (1, Z9-16:OAc; 2, Z11-16:OAc; 3, 16:OAc; 4, Z14-16:OAc). (B) Plot of canonical discriminant function scores for each species or strain for the first two functions accounting for 89.2% and 10.8% of the total variance explained. The four variables were absolute amount of individual compounds, all transformed (Y = log10 (amount + 0.1)).Back to article page
