Can the introduced genes be transferred to other species?

No, Aedes aegypti mosquitoes cannot produce viable offspring with other insects in the wild, not even with other species of mosquito. Therefore the genes are restricted to this single species of mosquito. Animals that eat the OX513A Aedes aegypti mosquito will be exposed to nutritional elements – protein, fat, carbohydrate and others – as they would from eating any mosquito, but they cannot take up genes through this route. Aedes aegypti is not a keystone species, meaning that it does not occupy a significant place in the food chain and if it’s eliminated from an area animals will have other prey. In most countries Aedes aegypti is not an indigenous mosquito, it was moved to that country by people, so it never occupied any part of the food chain or ecosystem prior to introduction. It is also under constant control by other methods, so nothing is reliant on it.
