Popis: BackgroundAedes albopictus is an invasive mosquito species of global medical concern as its distribution has recently expanded to Africa, the Americas and Europe. In the absence of prophylaxis protecting human populations from emerging arboviruses transmitted by this mosquito species, the most straightforward control measures rely on the suppression or manipulation of vector natural populations. A number of environmental-friendly methods using innundative releases of sterilizing males are currently under development. However, these strategies are still lacking an efficient sexing method required for mass production of males.ResultsWe present the first Genetic Sexing Strain (GSS) in Ae. albopictus, hereafter referred as TiCoq, obtained by sex linkage of rdl gene conferring dieldrin resistance. Hatching rate, larval survival and sex ratio were followed during twelve generations. The use of dieldrin at third larval stage allowed selecting 98% of males on average.ConclusionA good production rate of TiCoq males makes this GSS suitable for any control method based on mass production of Ae. albopictus sterilizing males. Despite limitations resulting from affected egg hatch as well as the nature of the used insecticide, the construction of this GSS paves the way for industrial sex separation of Ae. albopictus.
