Abstract

A bioassay was developed to compare pine outer-bark constituents extracted chemically from five species of southern pines. Extracts from inner and outer bark were also compared. Extracts from the outer bark of shortleaf pine elicited the greatest number of biting responses which significantly exceeded the controls. Beetles responded more often to extracts from the outer bark than to those from the inner bark.
