Our first results

In a series of lab and field assays, containers of different shapes and sizes that mimicked typical mosquito ovipositing sites were filled with tap water. We applied A. aegypti larvae and our EPN to the containers.

 

 

In a few days 85-100% of the larvae had been killed. That´s how healthy (left) and killed (right) mosquito larvae look like.

 

But at this point we cannot assure that our EPN will be a great biocontrol agent to fight A. aegypti. To the dispair of health officials worldwide, the mosquito females learned to oviposit in any kind of human-generated water container that you can think of.

 

So we must challenge the efficacy of our EPN in a range of real situations, hoping that it will remain highly efficient at killing A. aegypti larvae.
