Neuropeptides are endogenous active substances that widely exist in multicellular biological nerve tissue and participate in the function of the nervous system, and most of them act on neuropeptide receptors. In insects, neuropeptides and their receptors play important roles in controlling a multitude of physiological processes. In this project, we sequenced the transcriptome from twelve tissues of the Asian citrus psyllid, Kuwayama. A total of 40 candidate neuropeptide genes and 42 neuropeptide receptor genes were identified. Among the neuropeptide receptor genes, 35 of them belong to the A-family (or rhodopsin-like), four of them belong to the B-family (or secretin-like), and three of them are leucine-rich repeat-containing G-protein-coupled receptors. The expression profile of the 82 genes across developmental stages was determined by qRT-PCR. Our study provides the first investigation on the genes of neuropeptides and their receptors in , which may play key roles in regulating the physiology and behaviors of .
神经肽是广泛存在于多细胞生物神经组织中的内源性活性物质，参与神经系统的功能，其中大多数作用于神经肽受体。在昆虫中，神经肽及其受体在控制多种生理过程中起着重要作用。在这个项目中，我们对亚洲柑橘木虱 Kuwayama 的 12 种组织进行了转录组测序。总共鉴定出 40 个候选神经肽基因和 42 个神经肽受体基因。在神经肽受体基因中，其中 35 个属于 A 家族（或视蛋白样），4 个属于 B 家族（或分泌素样），3 个是富含亮氨酸重复的 G 蛋白偶联受体。通过 qRT-PCR 确定了 82 个基因在发育阶段的表达谱。我们的研究首次对 的神经肽及其受体基因进行了研究，这些基因可能在调节 的生理学和行为中发挥关键作用。
