Behavioral Response of Plum Curculio, Conotrachelus nenuphar, to Synthetic Fruit Volatile Lures and the Male-Produced Aggregation Pheromone

Figure 2

Response of plum curculio to combinations of commercial lures of benzaldehyde (BZ), plum essence (PE), and grandisoic acid (GA) in four-choice olfactometer bioassays. In each binary test, PE was compared against any two combinations of the three lures: (a) PE versus BZ + PE, (b) PE versus BZ + GA, and (c) PE versus PE + GA. Groups of five weevils of either sex were released per test in the olfactometer and replicated six times. Means for each sex having no letter in common are significantly different (ANOVA, Tukey-Kramer HSD, ).
