1-(1H-pyrrol-2-yl)-1,2-propandione is a crucial pheromone component of the rare North American cerambycid beetle Dryobius sexnotatus
… compound alone. Adults of another cerambycine, Xylotrechus colonus (F.), were attracted by the ketol, consistent with its being the primary component of the pheromone of this species, and attraction was not influenced by the presence of the pyrrole. This study attests to the effectiveness of …

Chemically-Mediated Mate Location and Recognition in Longhorned Beetles (Coleoptera: Cerambycidae)
… the female-produced contact pheromone of Xylotrechus colonus F, M. robiniae, and M. caryae. I then explore the use of synthetic hydrocarbons in mark-recapture studies. In the final chapter, I study the genetic structure of the Asian longhorned beetle, Anoplophora glabripennis Motschulsky, …

Blending synthetic pheromones of cerambycid beetles to develop trap lures that simultaneously attract multiple species
… acuminatus (F.), Neoclytus mucronatus (F.), and Xylotrechus colonus (F.). Beetles of these species were significantly attracted to synthetic blends that contained their pheromone components (isomers of 3-hydroxy-2-hexanone and/or 2,3-hexanediol), despite the presence of pheromone components of …

Effect of trap height on abundance and species diversity of cerambycid beetles captured in forests of east-central Illinois
… aereus (Newman), Phymatodes lengi (Joutel) and Xylotrechus colonus (F.), and the lamiine Astylidius parvus (LeConte). Most adult P. lengi were trapped in the mid canopy, whereas the remaining species were captured primarily in the understory. These findings suggest that trapping surveys of …

Factors contributing to variation in cuticular hydrocarbon profiles of two species of longhorned beetles (Coleoptera: Cerambycidae)
… North America, Neoclytus acuminatus (F.) and Xylotrechus colonus F. The cuticular wax layer of N. acuminatus comprises at least 20 hydrocarbons ranging from C24 to C29, three of which serve as the contact pheromone of females. The wax layer of X. colonus contains at least 17 hydrocarbons that …

Use of sensory information by cerambycids and their natural enemies to locate resources and mates
… the eggs and pheromones of the rustic borer, Xylotrechus colonus (F.) in two field experiments. The first experiment evaluated the role of location and pheromones on the rate of attack on eggs of X. colonus, whereas the second experiment addressed the role of pheromones in modulating response …
