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

Figure 1

Response of plum curculio to commercial lures of benzaldehyde (BZ), plum essence (PE), and grandisoic acid (GA) in four-choice olfactometer bioassays. In each test, two lure treatments (binary test) and two controls were compared: (a) BZ versus PE; (b) PE versus GA; and (c) BZ versus GA. In this figure and Figure 2, Control 1 = air and Control 2 = empty microcentrifuge vial. 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, ).
