Extracts with these metabolites produced by three isolates killed 100 percent of mosquito larvae within 24 hours of exposure. Killing mosquito larvae before they grow into adult mosquitoes is a common control method since the insects reproduce so quickly. More than 100 of the isolates killed all of the mosquito larvae within a week and 37 of those killed the larvae within three days. Those 37 isolates represented 20 genera of bacteria, many of which have not previously been identified for use in biopesticides, according to Dimopoulos. This method is promising because it suggests that an insecticide using this bacteria would not depend on the microbes staying alive.
