摘要

Abstract Atrijuglans hetaohei Yang (Lepidoptera: Gelechioidea) is one of the major pests that can seriously damage the walnut tree, leading to harvest loss. Sex pheromones regulate mating communication and reproduction in insects and provide targets for developing a novel pest control strategy. In this study, by transcriptomic sequencing and analysis of the female pheromone gland (PG) and male genitalia of A. hetaohei, we identified 92 putative genes, of which 7 desaturases (Dess), 8 fatty acyl reductases (FARs), 4 fatty acid synthetases (FASs), 2 aldehyde oxidases (AOXs), 4 acetyltransferases (ACTs), 1 chemosensory protein (CSP), and 2 odorant‐binding proteins (OBPs) were predominantly expressed in the female PG, while 5 Dess, 11 FARs, 7 FASs, 6 AOXs, 1 ACT, and 1 CSP showed more robust expression in the male genitalia. Moreover, phylogenetic analysis revealed that 7 Dess and 1 FAR were grouped with genes involved in pheromone synthesis in other Lepidoptera species. Thus, we proposed that these candidate genes are possibly involved in the sex pheromone biosynthetic pathway in A. hetaohei. Our findings will provide a solid genetic basis for further exploring the function of the tissue‐biased genes and may be useful to screen potential targets for interfering chemical communication in A. hetaohei.
