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-multistriatus01308nas a2200217   4500008004100000020001400041245013700055210006900192260001300261300001000274490000800284520052600292653002400818100001900842700001300861700001400874700002900888700001500917700002300932856013500955       2010                        eng d  a0071-073300aFirst records of the banded elm bark beetle Scolytus schevyrewi Semenov (Coleoptera: Curculionidae: Scolytinae), in British Columbia0 aFirst records of the banded elm bark beetle Scolytus schevyrewi   cDecember  a21-240 v1073 aThe banded elm bark beetle, Scolytus schevyrewi Semenov was detected for the first time in British Columbia near Kelowna during 2010. Fifty-eight S. schevyrewi were captured in an experiment that targeted the European elm bark beetle, Scolytus nniltistriatus (Marsham). It was a test of the efficacy of a new trap design relative to the multiple funnel trap currently used in surveillance programs for invasive bark- and wood-boring Coleoptera. Data on the seasonal occurrence of the banded elm bark beetle are presented.10aScolytus schevyrewi1 aHumble, L., M.1 aJohn, E.1 aSmith, J.1 aZilahi-Balogh, G., M.

The results showed that there were no significant differences in antenna morphological characters and sensor's distribution between the male and female. Majority of sensilla spreaded on the club of the antennae and occupied 98. 4% of all sensilla. The sensilla could be divided into four types: zigzag sensillum, bud-shaped sensillum, basiconca sensillum and chaeticum sensillum. These types respectively accounted for 57.7%, 28.6%, 12.6%, and 1.1% of the total sensilla. Zigzag sensilla distributed on all parts of antennae, among which sensilla on the club accounted for 99. 2% of total sensilla. However, sensilla on the scape and fanicles had approximately 0. 8% . Bud-shaped sensilla were buried beneath the zigzag sensilla on the club or distributed on the edges of club. Basiconca sensillum scattered on the edge of the club, and blended with bud-shaped sensilla while chaeticum sensilla distributed on the joint of the scape and funicle.10amorphology10aScolytus schevyrewi1 aFan, Linhua1 aLi, Yonghong1 aZhang, Jintong1 aLuo, Yuoqing1 aZong, Shixiang1 aYang, Meihong  uhttps://weevil.myspecies.info/antennae-structure-scolytus-schevyrewi-observed-scanning-electron-microscope01741nas a2200205   4500008004100000245009300041210006900134260000800203300001200211490000700223520105600230653002401286100001601310700002001326700001601346700001801362700002001380700001901400856011601419       2011                        eng d00aMorphological traits and bionomics of Scolytus schevyrewi Seme.

(Coleoptera: Scolytidae) is one of the elm boring pests. The morphological traits and bionomics of BEBB, including life cycle, adult lifespan, habits and mating behaviors, were observed in the laboratory and in the field in Yanchi county, Ningxia Province. There were two generations of BEBB per year. The pest overwintered in the form of mature larvae (98.2%) and pupae (1.8%). Mature larvae began to pupate in early May with a peak of pupation in mid May. Adults started to emerge from late May with a peak in early June. Second generation larvae pupated from late June till early July with a peak in late July and pupation ending in early August. The average lifespan of female and male adults was significantly different; (27.14 [plus or minus] 3.74) d for females and (16.86 [plus or minus] 4.13) d for males (P < 0.05). Diapause was not observed. Four kinds of natural enemies of BEBB; Elachistocontrum sp., Pedieuloids ventricosus Newport, Thansimus sp. and Labidura sp., were found.10aScolytus schevyrewi1 aFan, Li-Hua1 aZhang, Jin-Tong1 aLi, Yue-Hua1 aLuo, You-Qing1 aZong, Shi-Xiang1 aYang, Mei-Hong  uhttps://weevil.myspecies.info/morphological-traits-and-bionomics-scolytus-schevyrewi-seme-coleoptera-scolytidae01040nas a2200145   4500008004100000245024300041210006900284260000900353300001200362490000700374520039700381653002400778100002300802856006900825       2010                        eng d00aThe Banded Elm Bark Beetle, Scolytus schevyrewi Semenov (Coleoptera, Curculionidae, Scolytinae) in North America: a taxonomic review and modifications to the Wood (1982) key to the species of Scolytus Geoffroy in North and Central America0 aBanded Elm Bark Beetle Scolytus schevyrewi Semenov Coleoptera Cu  c2010  a207-2180 v563 aIn 2003, an Asian bark beetle, Scolytus schevyrewi Semenov (Coleoptera: Curculionidae: Scolytinae), the banded elm bark beetle, was detected for the first time in North America.
