Further contributions to the longhorn beetle (Coleoptera, Cerambycidae) fauna of New Brunswick and Nova Scotia, Canada

Abstract

Sixteen species of Cerambycidae are newly recorded for New Brunswick, Canada; Arhopalus obsoletus (Randall), Atimia confusa confusa (Say), Callidium frigidum Casey, Phymatodes amoenus (Say), Phymatodes testaceus (Linnaeus), Neoclytus mucronatus mucronatus (Fabricius), Xylotrechus aceris Fisher, Xylotrechus sagittatus sagittatus (Germar), Tylonotus bimaculatus Haldeman, Lepturges angulatus (LeConte), Lepturges symmetricus (Haldeman), Urgleptes querci (Fitch), Oplosia nubila (LeConte), Eupogonius subarmatus (LeConte), Monochamus carolinensis (Olivier), and Pogonocherus parvulus LeConte. Urgleptes signatus (LeConte) and Urgleptes querci are newly recorded from Nova Scotia. All but two specimens were collected in 12-funnel Lindgren traps. Xylotrechus aceris, Tylonotus bimaculatus, Lepturges angulatus, Lepturges symmetricus, Urgleptes signatus (NS), and Pogonocherus parvulus were detected exclusively in traps deployed in the forest canopy, and most individuals of Oplosia nubila and Monochamus carolinensis were captured in canopy traps. Arhopalus obsoletus, Atimia confusa confusa, Callidium frigidum, Phymatodes testaceus, and Xylotrechus sagittatus sagittatus were captured almost exclusively in traps near (1 m above) the forest floor. These results highlight the importance of sampling both the understory and upper canopy when using traps for surveying diversity of Cerambycidae.

Effect of semiochemicals and trap height on catch of Neocerambyx raddei in Jilin province, China

“…Traps placed in the middle or high canopy of oak trees captured more N. raddei than those placed in the understorey, indicating that canopy traps would be more efficacious for surveys and mass trapping than understorey traps. Previous studies have found that the species composition of longhorn beetles in traps differs between the forest canopy and the understorey (Graham et al, 2012;Dodds, 2014;Webster et al, 2016). Feeding habits of larvae and adults may influence whether beetles were captured in canopy or understorey traps.…”

Further contributions to the Coleoptera fauna of New Brunswick with an addition to the fauna of Nova Scotia, Canada

“…However, data on attractants were not collected for non-target species. See Webster et al (2012r), Hughes et al (2014), and Webster et al (2016) for additional details of the lures and methods used to deploy Lindgren traps and collect samples. A description of the habitat was recorded for all specimens collected during this survey.…”

“…Recently, Pelletier and Hébert (2014) reviewed the Cantharidae of eastern Canada and reported 19 species new to New Brunswick. Most recently, Webster et al (2016) newly reported an additional 16 species of Cerambycidae for the province. These baseline biodiversity data are important for documentation of changes in our ecosystems due to human intervention and climate change.…”

Further contributions to the staphylinid fauna of New Brunswick, Canada, and the USA, with descriptions of two new Proteinus species (Coleoptera, Staphylinidae)

“…Traps were baited with various combinations of lures for detecting Cerambycidae. See Webster et al (2012b), Hughes et al (2014), and Webster et al (2016a) for details of the lures and methods used to deploy Lindgren traps and collect samples. A description of the habitat was recorded for all specimens collected during this survey.…”
