The systemic insecticide imidacloprid may be applied to deciduous trees for control of the Asian longhorned beetle, an invasive wood-boring insect. Senescent leaves falling from systemically treated trees contain imidacloprid concentrations that could pose a risk to natural decomposer organisms. We examined the effects of foliar imidacloprid concentrations on decomposer organisms by adding leav...

Background: Wood-feeding beetles harbor an ecologically rich and taxonomically diverse assemblage of gut microbes that appear to promote survival in woody tissue, which is devoid of nitrogen and essential nutrients. Nevertheless, the contributions of these apparent symbionts to digestive physiology and nutritional ecology remain uncharacterized in most beetle lineages. Results: Through parallel...

Olfactory proteins form the basis of insect olfactory recognition, which is crucial for host identification, mating, and oviposition. Using transcriptome analysis of Anoplophora glabripennis antenna, we identified 42 odorant-binding proteins (OBPs), 12 chemosensory proteins (CSPs), 14 pheromone-degrading enzymes (PDEs), 1 odorant-degrading enzymes (ODE), 37 odorant receptors (ORs), 11 gustatory...

Abstract The genus Anoplophora (Coleoptera: Cerambycidae) is among the most well-known insect genera in invasive entomology and represented by 2 noted alien species: Asian longhorned beetle (Anoplophora glabripennis (Motschulsky, 1854)) Citrus chinensis (Forster, 1771)). In this study, a new non-native species belonging to Anoplophora, horsfieldii (Hope, 1843), has been discovered on Jeju Islan...

We conducted 2 markÐrecapture experiments in urban landscapes to examine the dispersal behavior of the eucalyptus longhorned borer, Phoracantha semipunctata (F.), a crepuscular beetle whose larvae bore into woody tissues of stressed or weakened eucalypts and fallen branches. Temporal changes in attractiveness of trees to beetles resulted in a correlation between beetle abundance and sampledate....

Abstract A reproductive population of the Asian longhorned beetle, Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), an adventive insect from Asia, was discovered in 2003 urban landscape Ontario, Canada. This polyphagous which attacks maples, Acer spp. (Sapindaceae), had potential to seriously and permanently alter composition structure forests eastern North America. The Canadi...
