Expression profile and functional characterization of odorant binding proteins in a forest pest, Dioryctria abietella (Lepidoptera: Pyralidae).

In the forest ecosystem dominated by the Pinaceae plants, this boring pest Dioryctria abietella is subject to a variety of odorants derived from host and nonhost plants, in which olfactory-related proteins enriched in antennae are key behavioral modulators for the orientation of feeding and ovipositing hosts. Here, we addressed the odorant binding protein (OBP) gene family in D. abietella.

Two Antenna-Enriched Odorant Binding Proteins in Dioryctria abietella Tuned to General Odorants and Insecticides.

The management of forest pests has become a significant challenge, particularly for wood borers, because they spend most of the time in the trunks or cones. The coneworm, Dioryctria abietella, is a representative of cone borers as its larvae feed on the cones of Pinaceae plants. The molecular mechanisms underlying the interactions between this species and host plants or habitats can assist in developing strategies for pest control.

Identification and characterization of candidate detoxification genes in Gahan (Coleoptera: Cerambycidae).

The wood-boring beetles, including the majority of Cerambycidae, have developed the ability to metabolize a variety of toxic compounds derived from host plants and the surrounding environment. However, detoxification mechanisms underlying the evolutionary adaptation of a cerambycid beetle to hosts and habitats are largely unexplored. Here, we characterized three key gene families in relation to detoxification (cytochrome P450 monooxygenases: P450s, carboxylesterases: COEs and glutathione-S-transferases: GSTs), by combinations of transcriptomics, gene identification, phylogenetics and expression profiles.

Genome-Wide Analysis of Odorant-Binding Proteins in with Focus on the Perception of Two PxutGOBPs to Host Odorants and Insecticides.

In this study, we annotated 49 odorant-binding proteins (OBPs) in , with four novel genes and seven improved sequences. Expression profiles identified numerous OBPs in antennae or reproductive tissues. Using two antenna-enriched general OBPs (PxutGOBP1 and PxutGOBP2) as targets, we screened three key compounds by a reverse chemical ecology strategy.

Combined transcriptomic, proteomic and genomic analysis identifies reproductive-related proteins and potential modulators of female behaviors in Spodoptera litura.

The common cutworm, Spodoptera litura, is a polyandrous moth with high reproductive ability. Sexual reproduction is a unique strategy for survival and reproduction of population in this species. However, to date available information about its reproductive genes is rare.

Suppression of Expression Enhances the Susceptibility of to .

Transferrins (Trfs) are multifunctional proteins with key functions in iron transport. In the present study, a () from was identified and characterized. The consisted of a 2046-bp open reading frame, which encoded a 681 amino acid protein with a molecular weight of 73.
