气味结合蛋白（OBPs）和化学感觉蛋白（CSPs）在昆虫化学感觉系统中发挥着重要作用。在亚洲玉米（鳞翅目：革螨科）中，只有一小部分对其表达模式进行了研究。在这项研究中，我们使用定量RT-PCR比较了24个OBPs和19个csp在性别之间的表达水平。在处女个体中观察到17个obp和7个csp的性别偏向表达。交配后，18个OBPs和10个CSP的表达水平发生了变化，导致16个OBPs和1个CSP的表达存在性别偏倚。在9个obp和2个csp中，交配的影响是性别特异性的。这些结果表明两性分子组成存在差异，并可能表明在o的化学感觉系统中OBP和CSP基因之间存在功能差异。furnacalis。
Odorant-binding proteins (OBPs) and chemosensory proteins (CSPs) play important roles in insect chemosensory systems. In the Asian corn borerOstrinia furnacalis(Guenée) (Lepidoptera: Crambidae), only a fraction of them have been examined for their expression patterns. In this study, we compared the expression levels of 24 OBPs and 19 CSPs between sexes using quantitative RT-PCR. Sexually biased expression was observed for 17 OBPs and 7 CSPs in virgin individuals. Expression levels of 18 OBPs and 10 CSPs changed after mating, resulting in sexually biased expression in 16 OBPs and 1 CSP. The effect of mating was sex-specific in 9 OBPs and 2 CSPs. These results suggest a sexually divergent molecular composition and may indicate a functional divide between OBP and CSP genes in the chemosensory system ofO. furnacalis.
