I´ve always worked with roundworms. Recently I discovered their ability to kill insects and I 've been working with them as biocontrol agents of agricultural and urban pests. I believe we can lower the adult mosquito population if we focus on the larval stage. So far, our results showed great control, but we still need to check if the agents will survive and infect the mosquito larvae in places where they are normally found. Roundworms can be a wonderful tool, if we know how to manage them.
