Abstract:

Abstract: Mosquito-borne diseases such as malaria, dengue, Zika and Japanese encephalitis have imposed a severe burden on global public health. Mosquito control remains the main remedy to prevent and control mosquito-borne diseases. Mosquito control requires comprehensive measures; biological control, such as the sterile insect technique (SIT) which aims at suppressing pest population size, will become one of its most important components due to its species-specificity, safety, effectiveness, and environmental-friendliness. The release of high-quality sterile males is one of the key factors for the success of SIT, while intensive mass rearing and irradiation-induced sterility of male mosquitoes will affect sterile males qualities. Mosquito guts are inhabited by numerous microbes that play important roles in the growth and development, invasion resistance, and immune regulation of the hosts. In this article, we review the species and roles of mosquito gut microbiotas, analyze the potential relationship between gut microbiotas and weakening of sterile male mosquitoes. We also investigate the application prospects of gut microbiotas in SIT-based mosquito control, i.e., improving the efficacy of SIT-based mosquito control by reducing or repairing the weakening of sterile male mosquitoes through mosquito gut microbiotas.

摘要：

疟疾、登革热、寨卡病毒病及流行性乙型脑炎等蚊媒传染病对全球公共卫生造成了严重负担。目前大部分蚊媒传染病预防与控制以媒介蚊虫控制为主。控制媒介蚊虫需要采取综合防制措施，其中生物防制如以控制有害昆虫种群为目的的昆虫不育技术，因其特异性强、安全有效、绿色环保，将成为蚊媒综合防制措施的重要组成部分。释放高质量的绝育雄虫是昆虫不育技术成功的关键保障之一，而集约化生产操作、诱导雄虫绝育的辐照，均会影响绝育雄虫的质量。蚊虫肠道内栖息着大量微生物，这些微生物在宿主的生长发育、抵御侵害、免疫调控等方面发挥着重要作用。该文综述了蚊虫肠道微生物的种类和功能，分析了肠道微生物与绝育雄蚊“致弱”的潜在关系，并展望肠道微生物在昆虫不育技术中控制蚊虫的应用前景，即利用蚊虫肠道微生物群来减缓或修复绝育雄蚊的“致弱”，从而提升昆虫不育技术控制蚊媒的效率。
