“…The PG of the female moth is a specialized tissue and has been extensively characterized with respect to transcriptomics, gene identification and gene function ( Ma & Ramaswamy, 2003 ; Jurenka, 2021 ). In the present study, we compared the numbers of genes associated with the sex pheromone production, representing nine pheromone biosynthesis enzyme families and one pheromone degradation enzyme family from 24 moth species of nine families.…”

“…The chemical communication among moths is mediated primarily by female sex pheromones released by a differentiated tissue, pheromone gland (PG). The sex pheromones produced by the PGs are generally a blend of multiple components, with a unique ratio serving as species recognition (intraspecific communication) and reproductive isolation (interspecific communication) ( Tillman et al, 1999 ; Raina et al, 2000 ; Jurenka, 2021 ). Thus, it is of particular significance to understand how the female moths biosynthesize sex pheromones in the PGs, and to identify the genes associated with the pheromone production and degradation.…”

“…Thus, it is of particular significance to understand how the female moths biosynthesize sex pheromones in the PGs, and to identify the genes associated with the pheromone production and degradation. To date, the PG transcriptomes of at least 25 moths from 10 families have been sequenced and characterized, including a model lepidopteran moth Bombyx mori and Achelura yunnanensis presented in this study (see Table 1 ; Zhang et al, 2014a ; Jurenka, 2021 ). However, in the Zygaenidae family the transcriptomic data and related genes in the PG tissues have not been reported, restricting our knowledge of sex pheromone evolution and genetic variation across zygaenid moths.…”

“…In some case, the long-chain unsaturated fatty acids are shortened by β -oxidation enzymes to further increase the diversity of species-specific pheromones ( Bjostad, Wolf & Roelofs, 1987 ). Lastly, in most moths a terminal functional group (–OH, –Ald or –OAc) is formed by fatty acyl-CoA reductases (FARs), alcohol oxidases/dehydrogenases (AOs/ADHs) or acetyltransferases (ATFs) ( Teal & Tumlinson, 1986 ; Morse & Meighen, 1987 ; Moto et al, 2003 ; Lienard et al, 2010 ; Hagstrom et al, 2012 ; Jurenka, 2021 ).…”

“…Recently, the sensilla on chemosensory tissues and the genes involved in chemosensation in this species have been characterized ( Li et al, 2020 ; Li et al, 2021 ), greatly enhancing our understanding of intra- and interspecific interactions. Notably, although the PG transcriptomes of 24 moth species are available (see Table 1 ; Zhang et al, 2014a ; Jurenka, 2021 ), in Zygaenidae the related transcriptomes and the genes have not yet been surveyed to date. Here, we sequenced and assembled the transcriptome of the PGs and 12 other tissues previously sequenced ( Li et al, 2021 ).…”

In most moth species, sex pheromones responsible for mating and communication of both sexes are primarily produced by the pheromone glands (PGs) of female moths. Although the PG transcriptomes and pheromone production related genes from 24 moth species have been characterized, studies on the related information remain unknown in the Zygaenidae family. Here, we sequenced the PG transcriptome of a zygaenid moth, Achelura yunnanensis. Such the sequencing resulted in the yields of 47,632,610 clean reads that were assembled into 54,297 unigenes, coupled with RNA sequencing data from 12 other tissues. Based on the transcriptome, a total of 191 genes encoding pheromone biosynthesis and degradation enzymes were identified, 161 of which were predicted to have full-length sequences. A comparative analysis among 24 moth species of nine families indicated that the numbers of the genes were variable, ranging from 14 in two Grapholita species to 191 in A. yunnanensis. Phylogenetic analysis in parallel with the expression data highlighted some key genes, including three △9 and four △11 desaturases, four fatty acyl-CoA reductases (FARs) clustering in the pgFAR clade, and three significantly antennae-enriched aldehyde oxidases. An extensive tissue- and sex- expression profile revealed a broad distribution of the genes, in which 128 relatives were detected in the PGs and 127 in the antennae. This study reports, for the first time, the gene repertoires associated with the pheromone production in Zygaenidae, and provides a valuable resource for exploring putative roles of the PG-enriched genes in A. yunnanensis.

BACKGROUND: (Z,E)-9,12-tetradecadienyl acetate (ZETA, Z9,E12-14:OAc) is a major sex pheromone component for many stored-product moth species. This pheromone is used worldwide for mating disruption, detection, monitoring, and mass trapping in raw and processed food storage facilities. In this study, we demonstrate the biological production of ZETA pheromone by engineered yeast Saccharomyces cerevisiae. RESULTS:We mined the pheromone gland transcriptome data of the almond moth, Ephestia (Cadra) cautella (Walker), to trace a novel E12 fatty acyl desaturase and expressed candidates heterologously in yeast and Sf9 systems. Furthermore, we demonstrated a tailor-made ZETA pheromone bioproduction in yeast through metabolic engineering using this E12 desaturase, in combination with three genes from various sources coding for a Z9 desaturase, a fatty acyl reductase, and an acetyltransferase, respectively. Electrophysiological assays (gas chromatography coupled to an electroantennographic detector) proved that the transgenic yeast-produced ZETA pheromone component elicits distinct antennal responses.CONCLUSION: The reconstructed biosynthetic pathway in yeast efficiently produces ZETA pheromone, leaves an undetectable level of biosynthetic intermediates, and paves the way for the economically competitive high-demand ZETA pheromone's bioproduction technology for high-value storage pest control.

BACKGROUNDMating and oviposition are essential and closely coordinated events in the reproduction of moths. Although tyramine, a biogenic amine, can affect insect reproduction by binding its receptors, the specific regulatory mechanism has not yet been fully elucidated.RESULTSPlutella xylostella mutant with tyramine receptor 1 (TAR1) knockout (homozygous mutant with 7‐bp deletion, Mut7) was developed by the CRISPR/Cas9 system to investigate the effect of TAR1 knockout on the reproduction of the moth. Compared with wild‐type (WT), the egg yield of Mut7 female (Mut7F) was significantly lower, no significant difference was observed in the egg size and hatching ratio between the groups. Further analysis showed that TAR1 knockout adversely affected ovary development, characterized by shorter ovarioles and fewer mature oocyte. Additionally, TAR1 knockout significantly reduced the occurrence of mating, resulting in a decrease in egg yield in Mut7F. The amounts of sex pheromones were quantified using gas chromatography–mass spectrometry. Results showed that the amounts of sex pheromone released by Mut7F were significantly lower before mating. Correspondingly, the messenger RNA (mRNA) levels of sex pheromone biosynthesis enzymes, including acetyl‐CoA carboxylase (ACC) and desaturase (DES), were significantly lower in the Mut7F pheromone gland. The decreased sex pheromone biosynthesis in Mut7F, especially before re‐mating, may be related to the underexpression of pheromone biosynthesis‐activated neuropeptide (PBAN).CONCLUSIONOverall, this study investigated the effect of PxTAR1 on oviposition and mating of P. xylostella. We report for the first time that TAR1 knockout could reduce the sex pheromone biosynthesis. These findings provide insights for developing a novel integrated pest control strategy based on mating interference. © 2023 Society of Chemical Industry.
