Biology And Host Finding Of Predaceous Hister Beetles (Coleoptera: Histeridae) Associated With Ips Spp. (Coleoptera: Scolytidae) In Loblolly Pine (Pinus Taeda L.), William Pinson Shepherd
LSU Doctoral Dissertations
The most common predaceous Histeridae (Coleoptera) found associated with Ips engraver beetles (Coleoptera: Scolytidae) in Louisiana were Platysoma attenuata LeConte, Pla. cylindrica (Paykull), Pla. parallelum (Say), and Plegaderus transversus (Say). Seasonal abundance of histerids in flight traps coincided with Ips spp. activity in the area. Histerid adults arrived at loblolly pine (Pinus taeda L.) logs one wk after Ips attacks had begun. As a group, histerids exhibited a bimodal emergence pattern with the first peak occurring during Ips emergence and a second four wks later, indicating that they fed on bark beetles and associated organisms arriving later in the colonization …
