Six new species of Agrilus Curtis, 1825 (Coleoptera, Buprestidae, Agrilinae) from the Oriental Region related to the emerald ash borer, A. planipennis Fairmaire, 1888 and synonymy of Sarawakita Obenberger, 1924.

ABSTRACT: Six new species of Agrilus Curtis, 1825 with affinities to the emerald ash borer, Agrilus planipennis Fairmaire, 1888, are described from the Oriental Region: Agrilus crepuscularissp. n. (Malaysia); Agrilus pseudolubopetrisp. n. (Laos); Agrilus sapphirinussp. n.(Laos); Agrilus seramensissp. n.(Indonesia); Agrilus spineussp. n. (Malaysia); and Agrilus tomentipennissp. n. (Laos). The genus Sarawakita Obenberger, 1924 syn. nov. is considered a junior synonym of Agrilus.

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.
