Review of American Xyleborina (Coleoptera: Curculionidae: Scolytinae) Occurring North of Mexico, with an Illustrated Key
Ambrosia-feeding scolytids in the Xyleborina are the most abundant exotic bark beetles in North America and the need for a worldwide revision of this tribe hampers the ability to identify species, so an illustrated key is constructed and new species are reported and diagnosed. Expand
Morphology, Taxonomy, and Phylogenetics of Bark Beetles
This chapter summarizes the historical and contemporary taxonomy, phylogenetic relationships, morphological and molecular approaches, and information resources used in the classification of bark and… Expand
Standard percent DNA sequence difference for insects does not predict species boundaries.
- A. Cognato
- Journal of economic entomology
The reviewed studies suggest that a standard percent sequence divergence does not predict species boundaries among economically important insects. Expand
Standard Percent DNA Sequence Difference for Insects Does Not Predict Species Boundaries
- A. Cognato
- 1 August 2006
It is suggested that a standard percent sequence divergence does not predict species boundaries among economically important insects, as well as common occurrence of nonmonophyly among closely related species. Expand
Cladistic review of generic taxonomic characters in Xyleborina (Coleoptera: Curculionidae: Scolytinae)
The characters most useful for generic‐level taxonomy of Xyleborina were identified and their states refined and illustrated and an accompanying illustrated multiple‐entry electronic key for the updated xyleborine classification is published. Expand
Phylogeny of ips DeGeer species (Coleoptera: scolytidae) inferred from mitochondrial cytochrome oxidase I DNA sequence.
European Ips species do not form a monophyletic group, contrary to common usage, and are dispersed on the phylogenetic tree among North American species, indicating that a formal systematic revision of Ips is needed. Expand
Assessing the odd secondary structural properties of nuclear small subunit ribosomal RNA sequences (18S) of the twisted‐wing parasites (Insecta: Strepsiptera)
- Joseph J Gillespie, C. McKenna, +4 authors A. Cognato
- Biology, Medicine
- Insect molecular biology
- 1 December 2005
The entire sequence and secondary structure of the nuclear small subunit ribosomal RNA (SSU rRNA) gene (18S) from the twisted‐wing parasite Caenocholax fenyesi texensis is reported and no support for the previously recovered heterogeneity in the 18S molecules of strepsipterans is found. Expand
The age and phylogeny of wood boring weevils and the origin of subsociality.
The phylogenetic results were quite dependent on morphological data and it is concluded that more genetic loci must be sampled to improve phylogenetic resolution, however, some results such as the derived position of Scolytinae were consistent between morphological and molecular data. Expand
Genetic analysis of emerald ash borer (Agrilus planipennis Fairmaire) populations in Asia and North America
- A. Bray, L. Bauer, T. Poland, R. Haack, A. Cognato, James J. Smith
- Biological Invasions
- 24 February 2011
Using molecular markers to characterize the population genetic structure of EAB in its native and introduced range may provide valuable insights on the geographic origin, potential host range, invasion potential, and additional biological control agents for ongoing management efforts of this destructive wood-boring beetle.

Genetic Structure Among Pinyon Pine Beetle Populations (Scolytinae: Ips confusus)
Cl cladistic and nested clade analyses of mitochondrial DNA cytochrome oxidase I (mtDNA COI) sequence data revealed three main haplotype lineages, each associated with eastern, southwestern, and western geographic localities. Expand
