Abstract

Nine species of hymenopterous parasitoids were trapped on sticky traps as they were attracted to red cedar logs infested with the eastern jumper bark beetle, Phloeosinus dentatus (Say). All were successfully reared from infested logs. The parasitoids Cheiropachus arizoninsis (Ashmead), Eurytoma aequabilis Bugbee, Heydenia unica Cook & Davis, and Spathius impus Matthews were reared directly from P. dentatus larvae.

Five species of parasitoids reared from P. dentatus larvae or from infested logs commonly attack the southern pine beetle and Ips spp. beetles, indicating that P. dentatus may be an important alternate host when the other host populations are low.
