The Asian tiger mosquito, Aedes albopictus, is an invasive species and a vector for several significant human pathogens. Gaining deeper understanding of its reproductive biology offers valuable insights into evolutionary success may inform the development sustainable strategies to control spread. This study presents comprehensive structural functional characterization fruitless gene in Ae. albopictus (Aalfru), pivotal regulator sexual behavior insects. Through silico analysis combined with molecular genetics approaches, we identified high degree conservation fru structure regulation via sex-specific alternative splicing. Differently from Drosophila, aegypti, other dipteran orthologs, Aalfru starts 1-day-old embryos, rather than late larval stage. Functional using embryonic RNA interference (RNAi) demonstrated that, males transiently disrupted expression at stage showed deficits adult mating failed produce viable progeny. Our findings elucidate gene’s organization, developmental regulation, critical role courtship behavior, highlighting importance male albopictus.
