Aedes albopictus, the Asian tiger mosquito, is a vector of several arboviruses including dengue and chikungunya, and is also a significant nuisance mosquito. It is one of the most invasive of mosquitoes with a relentlessly increasing geographic distribution. Conventional control methods have so far failed to control Ae. albopictus adequately. Novel genetics-based strategies offer a promising alternative or aid towards efficient control of this mosquito. We describe here the isolation, characterisation and use of the Ae. albopictus Actin-4 gene to drive a dominant lethal gene in the indirect flight muscles of Ae. albopictus, thus inducing a conditional female-specific late-acting flightless phenotype. We also show that in this context, the Actin-4 regulatory regions from both Ae. albopictus and Ae. aegypti can be used to provide conditional female-specific flightlessness in either species. With the disease-transmitting females incapacitated, the female flightless phenotype encompasses a genetic sexing mechanism and would be suitable for controlling Ae. albopictus using a male-only release approach as part of an integrated pest management strategy. The Asian Tiger mosquito, Aedes albopictus, is a highly invasive species which took advantage of human activity to spread from South-East Asia to Africa, North and South America, and Europe in the past forty years. Beyond the annoying biting nuisance, this mosquito is also a significant public health threat, capable of transmitting dengue and responsible for an important chikungunya outbreak in the Indian Ocean in 2007. This mosquito is notoriously difficult to control using current methods, but control techniques involving the release of genetically sterile males have recently shown promising results against the closely related yellow fever mosquito, Aedes aegypti. Wild females inseminated by sterile males have non-viable progeny so if enough sterile males are released, the target population crashes. Female mosquitoes, even if sterile, would bite and potentially acquire and transmit pathogens, so it is crucial to minimise the release of such females. Here we describe the development of genetically engineered strains of the Asian Tiger mosquito to use in such control programmes: the females are unable to fly unless reared with an antidote, thus facilitating male-only releases. The daughters of released males will also be flightless, a lethal phenotype in the field, thus reducing the population and preventing disease transmission.
