ECOLOGY AND EVOLUTION 12/09/13 Release of genetically engineered insects: a framework to identify potential ecological effects. Abstract Genetically engineered (GE) insects have the potential to radically change pest management worldwide.
With recent approvals of GE insect releases, there is a need for a synthesized framework to evaluate their potential ecological and evolutionary effects. The effects may occur in two phases: a transitory phase when the focal population changes in density, and a steady state phase when it reaches a new, constant density. We review potential effects of a rapid change in insect density related to population outbreaks, biological control, invasive species, and other GE organisms to identify a comprehensive list of potential ecological and evolutionary effects of GE insect releases.
We apply this framework to the Anopheles gambiae mosquito – a malaria vector being engineered to suppress the wild mosquito population – to identify effects that may occur during the transitory and steady state phases after release.

Abstract The increasing burden of dengue, and the relative failure of traditional vector control programs highlight the need to develop new control methods.
SIT using self-limiting genetic technology is one such promising method. A self-limiting strain of Aedes aegypti, OX513A, has already reached the stage of field evaluation. Sustained releases of OX513A Ae. aegypti males led to 80% suppression of a target wild Ae. aegypti population in the Cayman Islands in 2010.

A new stage design Transgenic Aedes (PAT), which frees males genetically modified to combat wild insect, that transmits dengue, was started in the city of Bahia Jacobina.
Will be released approximately 4 million mosquitoes a week for the next three years to combat dengue. Result of an agreement between the Institute of Biomedical Sciences (ICB) and the USP biofactory Moscamed Brazil, PAT will release in this new stage, more than 430 million mosquitoes. "This is a pioneering project in the world.

PLOS 21/04/11 Engineered Resistance to Plasmodium falciparum Development in Transgenic Anopheles stephensi. Abstract Transposon-mediated transformation was used to produce Anopheles stephensi that express single-chain antibodies (scFvs) designed to target the human malaria parasite, Plasmodium falciparum.
The scFvs, m1C3, m4B7, and m2A10, are derived from mouse monoclonal antibodies that inhibit either ookinete invasion of the midgut or sporozoite invasion of salivary glands. The scFvs that target the parasite surface, m4B7 and m2A10, were fused to an Anopheles gambiae antimicrobial peptide, Cecropin A. Previously-characterized Anopheles cis-acting DNA regulatory elements were included in the transgenes to coordinate scFv production with parasite development. Gene amplification and immunoblot analyses showed promoter-specific increases in transgene expression in blood-fed females.
Author Summary Malaria eradication will require vector-control strategies that are both self-sustaining and not affected by migration of infected humans and mosquitoes. Figures Editor: Nora J. Introduction.
