Aedes albopictus
Oxitec developed a genetically modified version of "Aedes aegypti" to help control the transmission of mosquito-borne diseases. Oxitec created genetically-altered males of the species (OX513A) that produce the protein tTA, which negatively affects cell development. While it was presented as a sterile insect technique in a publication by Oxitec, this was disputed. One published study, successfully challenged by Oxitec and even some of the study's co-authors and now marked with an Editorial Expression of Concern stated that it found that the transgenic mosquitoes had successfully hybridized with the local "A. aegypti" population. In 2017 Oxitec started to develop a genetically modified version of the Asian tiger mosquito "Aedes albopictus".
