Figure 2. Response Indices for plum curculio adults during 2 hours of exposure 

 to water extracts of twigs (diamonds), leaves (squares), or fruit (triangles) from 

 Mcintosh trees at pink, bloom, petal fall, or 2, 3, 4, 5, or 6 weeks after bloom. If 

 the difference between two means of any stage exceeds 20 (based on a sample 

 size of 12), then the means are significantly different at odds of 19 to 1.
