Reliance on adult external morphological characters for identification can be problematic because of wide within-species variability and the need for good-quality specimens. The inability to identify developmental stages can also hamper early-detection programs. Using two character identification systems, genitalic (aedeagus) morphology, and DNA markers (random amplified polymorphic DNA polymerase chain reaction (RAPD-PCR)) to distinguish S. schevyrewi from S. multistriatus, we examined specimens from geographically distinct populations of both species collected from infested host trees or semiochemical-baited funnel traps. We found that aedeagus morphology can be used to identify the two species. The use of two oligonucleotide primers in the RAPD-PCR analysis yielded distinct DNA banding patterns for the two species. Species identification using RAPD-PCR analysis was validated by a blind test and used to make species identifications of larval specimens. These tools improve the ability to differentiate between S. schevyrewi and S. multistriatus at immature and adult stages, and could be developed and used for other scolytines as well.10aScolytus multistriatus10aScolytus schevyrewi1 aJohnson, Patricia, L.1 aHayes, Jane, L.1 aRinehart, John1 aSheppard, Walter, S.1 aSmith, Steven, E.  uhttps://weevil.myspecies.info/characterization-two-non-native-invasive-bark-beetles-scolytus-schevyrewi-and-scolytus-multistriatus02032nas a2200217   4500008004500000020001400045245009400059210006900153260001200222300001200234490000700246520130700253653001501560100002001575700002601595700002001621700002201641700001701663700001901680856011501699       2008                        Engldsh    a0885-609500aResponse of bark and woodboring beetles to host volatiles and wounding on western juniper0 aResponse of bark and woodboring beetles to host volatiles and wo  cOctober  a206-2150 v233 aIn central Oregon, management of western juniper (Juniperus occidentalis var. occidentalis Hook.) has included use of prescribed fire and mechanical removal. After these treatments, several species of bark and woodboring beetles have been observed on treated trees and also occasionally on trees outside management areas, suggesting that these insects might contribute to juniper mortality. In this 2-year (2002-2003) study, we identified bark and woodboring beetles that attack western juniper along with associated beetle predators and examined whether these insects can be manipulated for use in juniper management. Using funnel traps and sticky traps on trees wounded by pruning or treated with host volatiles (juniper berry oil, cade oil, and ethanol) that may attract insects, we captured beetles in the families Buprestidae, Cerambycidae, and Scolytidae (20 species in 17 genera) and known predators in the families Cleridae and Trogositidae (8 species in 7 genera). Cedar bark beetles (Phloeosinus spp.) were the most prevalent insects captured on trees treated with host volatiles and/or wounded. Treatments that included ethanol plus wounding were most attractive to these beetles. However, there was no obvious insect-caused damage or mortality of treated trees in either year of this study.10aScolytidae1 aHayes, Jane, L.1 aJohnson, Patricia, L.1 aEglitis, Andris1 aScott, Donald, W.1 aSpiegel, Lia1 aSchmitt, Craig  uhttps://weevil.myspecies.info/response-bark-and-woodboring-beetles-host-volatiles-and-wounding-western-juniper
