A nondestructive trap for Dendroctonus frontalis Zimmerman (Coleoptera: Scolytidae)
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 clerid Thanasimus 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.
