Oxitec is the world leader in application of synthetic biology to control of pest insects. Oxitec’s RIDL® technology relies on release of mass-reared genetically sterile (transgenic) male insects that mate with their wild pest counterparts, thereby causing a drop in population. RIDL efficacy is proven against the dengue mosquito, Ae. aegypti, reducing wild populations in Brazil by ca. 96%. A costly aspect of current technology is the means of selecting males only for release, important as the females blood-feed and transmit disease. This project aims to develop a novel method of producing male-only cohorts of RIDL mosquitoes (‘genetic sexing’) that would both markedly reduce costs and cement Oxitec’s leadership in the field. Next-generation sequencing datasets will be analysed to help develop new RIDL traits in Ae. aegypti mosquitoes, to increase the efficiency of applying our technology in the field. Development of targeted bioinformatics methodology, and successful engineering of a novel genetic sexing technique, will provide a pipeline for development of new RIDL traits in other pests important for public health and agriculture.

Oxitec是将合成生物学应用于害虫控制的世界领导者。Oxitec的RIDL®技术依赖于释放大量饲养的遗传不育（转基因）雄性昆虫，这些昆虫与野生害虫交配，从而导致种群数量下降。RIDL对登革热蚊子Ae.埃及，减少野生种群在巴西约。百分之九十六目前技术的一个昂贵方面是只选择雄性进行释放的手段，这一点很重要，因为雌性吸血并传播疾病。该项目旨在开发一种新的方法来生产RIDL蚊子的雄性群体（“遗传性别鉴定”），这将显着降低成本并巩固Oxitec在该领域的领导地位。将分析下一代测序数据集，以帮助在Ae中开发新的RIDL性状。埃及蚊子，以提高我们在该领域应用技术的效率。有针对性的生物信息学方法的发展，以及一种新的遗传性别鉴定技术的成功工程，将为在其他对公共卫生和农业重要的害虫中开发新的RIDL性状提供一个管道。
