Abstract

The odor produced by male Ips grandicollis attacking caged loblolly pine bolts was not very effective in attracting marked beetles. Only 2.4% of the 9,417 beetles released around the attracting attacks were recaptured.Unscreened infested bolts lost their attractiveness to responding beetles when about 27 attacks per square foot of bark surface had been reached. More beetles attacked bolts placed outside of a beetle producing area than those within. The latter indicates that a dispersal flight may be needed before response takes place.
