    Notes: Abstract The bucket trap is a lightweight device for capturing southern pine beetles in flight and retaining them either alive or dead for later examination. It is not messy like the sticky trap and not cumbersome like conventional live traps. Placing the bucket against a vertical silhouette increases the number of beetles caught. Few nontarget insects are captured except for the cleridThanasimus dubius. When the trap was baited with Frontalure, about 99% of the beetles trapped were male. When infested pine bolts were used as bait, roughly equal numbers of males and females were captured.

    Pheromone biosynthetic pathways: Conversion of ipsdienone to (−)-ipsdienol, a mechanism for enantioselective reduction in the male bark beetle,Ips paraconfusus (1984)

    Notes: Abstract The enantiomeric composition of the pheromone components (+)-ipsdienoI, e.e. 87.6%, and (−)-ipsenol, e.e. 93.8%, produced by the male bark beetleIps paraconfusus (Scolytidae) under natural conditions was determined by HPLC separation of their diastereomeric ester derivatives. Males confined in an atmosphere of ipsdienone produced (−)-ipsdienol, e.e. 28%, and (−)-ipsenol, e.e. 86%, indicating an enantiomeric selectivity in the conversion of the ketone to the alcohols. These findings demonstrate an enantioselective conversion mechanism in the biosynthetic pathway to the pheromones from myrcene, a host-plant terpene.
