After setbacks, good results!

Once we got our proposal funded, we jumped into the business of assessing the efficacy of entomopathogenic roundworms (ER) to kill larvae of the mosquito A. aegypti.  It was a disaster... the larva...

Here´s our "celebrity": Heterorhabditis indica LPP35. Each little white speck floating in the water is a roundworm. They are small but they can do wonders against agricultural and urban pests!

Biological control of the mosquito Aedes aegypti

Dear Dale, surplus nematodes - those applied to drains or water containers but not eaten by mosquito larvae - would certainly have no ecological effect. They must infect insects to survive, which other than mosquito larvae, are rare in water containers. Those applied to drains would eventually be flushed into the sewer system.
