Effects of culture medium and formulation on the larvicidal activity of the mosquito pathogen Lagenidium giganteum (Oomycetes: Lagenidiales) against Aedes aegypti

▶ Medium containing sunflower seed promoted the greatest production of zoospores. ▶ The LC50 value was 43.9 μl of total culture/ml against Aedes aegyti larvae. ▶ The formulation of culture with 2% pectin increased the larval mortality.
