Using tetramethylammonium hydroxide thermochemolysis, lignin degradation by two insect species, the Asian longhorned beetle and the Pacific dampwood termite, is shown and a single species of fungus is identified in the Fusarium solani/Nectria haematococca species complex that may be contributing to wood degradation.

Metagenomic Profiling Reveals Lignocellulose Degrading System in a Microbial Community Associated with a Wood-Feeding Beetle
A taxonomic and functional profile of a gut community derived from an invasive population of larval A. glabripennis collected from infested host trees is developed and genes that could have key roles in woody tissue digestion and nutrient acquisition are identified. Expand
Effect of Host Tree Species on Cellulase Activity and Bacterial Community Composition in the Gut of Larval Asian Longhorned Beetle
Results show that the host tree can impact both gut microbial community complexity and cellulase activity in A. glabripennis, and this community can be extremely variable when reared in different host trees. Expand
Effects of laccase on lignin depolymerization and enzymatic hydrolysis of ensiled corn stover.
The findings suggest that ensilage might provide a platform for biological pretreatment and demonstrate the potential of enzymes, either directly amended or expressed by microbes during ensilage, to maximize utilization of corn stover for cellulosic biofuels and other downstream fermentations.

An Evaluation of the Species Status of Bactrocera invadens and the Systematics of the Bactrocera dorsalis (Diptera: Tephritidae) Complex
This work sequenced one mitochondrial and two nuclear genes from 73 specimens belonging to 19 species to construct phylogenies and examine species relationships and limits within the genus Bactrocera and several species of the B. dorsalis complex-specifically addressing the placement of B. invadens.

Genome Annotation Generator: a simple tool for generating and correcting WGS annotation tables for NCBI submission
The Genome Annotation Generator is a consistent and user-friendly bioinformatics tool that can be used to generate a .tbl file that is consistent with the NCBI submission pipeline. Expand
Genome of the Asian longhorned beetle (Anoplophora glabripennis), a globally significant invasive species, reveals key functional and evolutionary innovations at the beetle–plant interface
Amplification and functional divergence of genes associated with specialized feeding on plants, including genes originally obtained via horizontal gene transfer from fungi and bacteria, contributed to the addition, expansion, and enhancement of the metabolic repertoire of the Asian longhorned beetle and to a lesser degree, other phytophagous insects.

Host plant species determines symbiotic bacterial community mediating suppression of plant defenses
Examination of suppression of JA-mediated defense in wild and cultivated hosts of Colorado potato beetles by chemical elicitors and their symbiotic bacteria demonstrates that host plants influence herbivore gut bacterial communities and consequently affect the herbivor’s ability to manipulateJA-mediated plant defenses.

Sequencing and De Novo Assembly of the Western Tarnished Plant Bug (Lygus hesperus) Transcriptome
The L. hesperus transcriptome advances the underlying molecular understanding of this arthropod pest by significantly increasing the number of known genes, and provides the basis for further exploration and understanding of the fundamental mechanisms of abiotic stress responses. Expand
Incongruence between molecules and morphology: A seven-gene phylogeny of Dacini fruit flies paves the way for reclassification (Diptera: Tephritidae).
The phylogeny confirms the monophyly of Dacus, Bactrocera, and Zeugodacus, however, most groups below the genus level are not monophyletic, and only through further revision will the authors be able to understand their evolution and clarify the taxonomy within this tribe. Expand
