The complete mitogenome of the Emerald Ash Borer (EAB), Agrilus planipennis (Insecta: Coleoptera: Buprestidae).

ABSTRACT: The complete mitogenome of the Emerald Ash Borer (EAB, Agrilus planipennis) was obtained by gleaning mitochondrial sequences from whole-genome Illumina sequencing data. The circular genome has 15,942 base pairs and contains 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs) and an A-T-rich region. All PCGs begin with ATN codons. The nucleotide composition is highly asymmetric (31.65% A, 40.25% T, 17.39% G, 10.71% C), with an overall A-T content of 71.9%. Phylogenetic analysis based on insect mitogenomes indicated that EAB is closely related to other Buprestoidea species, clustering most closely with Chrysochroa fulgidissima.

Project description:BackgroundInsects rely on olfaction to locate food, mates, and suitable oviposition sites for successful completion of their life cycle. Agrilus planipennis Fairmaire (emerald ash borer) is a serious invasive insect pest that has killed tens of millions of North American ash (Fraxinus spp) trees and threatens the very existence of the genus Fraxinus. Adult A. planipennis are attracted to host volatiles and conspecifics; however, to date no molecular knowledge exists on olfaction in A. planipennis. Hence, we undertook an antennae-specific transcriptomic study to identify the repertoire of odor processing genes involved in A. planipennis olfaction.Methodology and principal findingsWe acquired 139,085 Roche/454 GS FLX transcriptomic reads that were assembled into 30,615 high quality expressed sequence tags (ESTs), including 3,249 isotigs and 27,366 non-isotigs (contigs and singletons). Intriguingly, the majority of the A. planipennis antennal transcripts (59.72%) did not show similarity with sequences deposited in the non-redundant database of GenBank, potentially representing novel genes. Functional annotation and KEGG analysis revealed pathways associated with signaling and detoxification. Several odor processing genes (9 odorant binding proteins, 2 odorant receptors, 1 sensory neuron membrane protein and 134 odorant/xenobiotic degradation enzymes, including cytochrome P450s, glutathione-S-transferases; esterases, etc.) putatively involved in olfaction processes were identified. Quantitative PCR of candidate genes in male and female A. planipennis in different developmental stages revealed developmental- and sex-biased expression patterns.Conclusions and significanceThe antennal ESTs derived from A. planipennis constitute a rich molecular resource for the identification of genes potentially involved in the olfaction process of A. planipennis. These findings should help in understanding the processing of antennally-active compounds (e.g. 7-epi-sesquithujene) previously identified in this serious invasive pest.

Project description:The Agrilus occipitalis species-group is redefined and diagnosed. Two species from this group, Agrilus auriventris Saunders, 1873 and Agrilus occipitalis (Eschscholtz, 1822), are known as the serious pests of cultivated Citrus trees. Overall twenty-three taxa are included in the Agrilus occipitalis species-group. A complete list of references, type material, species examined and distribution is given for each taxon. The host plants, adult occurrence and altitude range is cited for most taxa. Habitus of all taxa and aedeagi of available males are pictured. Images of primary type specimens are provided. A character state matrix table for diagnostic characters is given for all taxa to facilitate their determination. The following new taxonomic and nomenclatural acts are proposed. New species:eight new species are described: Agrilus mucidus sp. n., Agrilus nebulosus sp. n., Agrilus picturatus sp. n., Agrilus pluvius sp. n., Agrilus pseudoambiguus sp. n., Agrilus tesselatus sp. n., Agrilus trepanatus sp. n. and Agrilus umrongso sp. n. Proposed synonyms: eight synonyms are proposed: celebicola Obenberger, 1924, syn. n. (synonym of occipitalis Eschscholtz, 1822); connexus Kerremans, 1900, syn. n. (synonym of occipitalis Eschscholtz, 1822); cupricauda Saunders, 1867 syn. n. (synonym of occipitalis Eschscholtz, 1822); evinadus Gory & Laporte, 1839, syn. n. (synonym of occipitalis Eschscholtz, 1822); nirius Obenberger, 1924 syn. reconfirmed (synonym of occipitalis Eschscholtz, 1822); oblatus Kerremans, 1900, syn. n. (synonym of occipitalis Eschscholtz, 1822); samoensis Blair, 1928, syn. n. (synonym of auriventris Saunders, 1873); tebinganus Obenberger, 1924, syn. n. (synonym of occipitalis Eschscholtz, 1822). New lectotype designations: six lectotypes are designated: Agrilus celebicola Obenberger, 1924; Agrilus cupricauda Saunders, 1867; Agrilus korenskyi Obenberger, 1923; Agrilus kurandae Obenberger, 1923; Agrilus nirius Obenberger, 1924; Agrilus nitidus Kerremans, 1898.
