—The potential for ecological and economic damage caused by invasive species is only beginning to be appreciated. A recently arrived, and particularly worrisome, invader in North America is the Asian longhorned beetle Anoplophora glabripennis (Motschulsky), the larvae of which damage trees and forests. The geographic extent and likely path of its possible invasion of North American forests, how...

Maternal exposure to an immune challenge can convey enhanced immunity to invertebrate offspring in the next generation. We investigated whether maternal exposure of the Asian longhorned beetle, Anoplophora glabripennis, to two species of the fungus Metarhizium or the bacterium Serratia marcescens elicited transgenerational immune priming (TGIP). We tested specificity of this protection and whet...

The predatory beetle Dastarcus helophoroides (Fairmaire) (Coleoptera: Bothrideridae) is a natural enemy of many longhorned beetles and is mainly distributed in both China and Japan. To date, no research on D. helophoroides P450 enzymes has been reported. In our study, for the better understanding of P450 enzymes in D. helophoroides, 100 novel cDNA fragments encoding cytochrome P450 were amplifi...

We conducted laboratory and Þeld studies to test the hypothesis that volatile pheromones mediate mate location in the longhorned beetle Prionus californicusMotschulsky (Coleoptera: Cerambyicidae), an important pest of many agricultural and ornamental plants. Males were strongly attracted to live females and to carcasses of freshly killed females in olfactometer bioassays.Males also responded st...

Commensalmicroorganismshave signiÞcant impacts on thehealthofmany insecthosts. Little is known, however, about the structure of commensal bacterial communities associatedwith the Cerambycidae, despite the important roles this large family of herbivorous endophytic insects plays in ecosystem processes, economic losses to ornamental and forest trees, and biological invasions. We analyzed the bact...

The invasive Asian cerambycid beetle Callidiellum rufipenne (Motschulsky), informally known as the Japanese cedar longhorned beetle, was first detected in North America in North Carolina in 1997. The beetle has since been detected in neighboring states and is expected to further expand its range. However, delineating the current distribution of C. rufipenne has been hindered by the lack of effi...

Taxonomic placement of the enigmatic monotypic Mexican longhorned beetle genus Vesperoctenus Bates is examined through inclusion in and reanalysis dataset Haddad et al. (2018, Systematic Entomology 43: 68–89). We describe discuss phylogenetic significance internal structures a recently collected V. flohri female from Sierra de la Laguna mountain range Mexico, same specimen which phylogenomic da...
