Research Interests
- My main interest is the study of the genetic basis of fertilization and mating behaviour in Anopheles mosquitoes, with the view to both answer basic biological questions and to develop new molecular and genetic tools for vector control programs.
- We are also involved in a series of projects aimed at developing tools for vector control methods, especially those based on the Sterile Insect Technique (SIT). SIT generally relies on the release of mass numbers of sterile male insects over large areas. As mating of these males with field females produces no progeny, if releases are effective then eradication or reduction of the field population will ensue. Considering that for malaria control male-only populations must be released, as females would contribute to disease transmission, efficient sexing methods to eliminate females from the released males must be in place. To this end, we have very recently accomplished the development of the first transgenic sexing strains for Anopheles mosquitoes, which allows an automated separation of male from female individuals. In this stains, the sperm-specific expression of an EGFP reporter gene allows the identification of male individuals at the 4th instar larval stage and throughout development.
- Recently we have started a project aimed at analyzing Anopheles genes that are involved in sex-determining pathway. We have identified, cloned and analyzed the Anopheles gambiae doublesex gene, the double-switch gene at the bottom of the sex-determining cascade, and we are now using this information to develop sexing strains and to identify other genes of the pathway.research 3
