| Using genetically modified mosquitoes to control vector-borne diseases will require specific, quantitative targets for the extent to which populations of competent mosquito vectors need to be reduced in order to produce predictable public-health outcomes. Unfortunately, dengue researchers do not have an entomological measure for predicting the risk of human dengue infection and disease that is as effective as they would like. The situation is further complicated by the fact that contemporary dengue control is based on the assumption, which has not been thoroughly tested, that a reduction in adult Aedes aegypti population densities will decrease risk of virus transmission. Ae. aegypti eradication is not considered feasible and there are no commercially... |
