Nosema Locustae is a microsporidium protozoan that is used to kill grasshoppers.[1]
Nosema Locustae causes grasshoppers to become slower, stop eating, and die after consuming it. The disease is contagious if other grasshoppers feed off of a deceased one.[2] In a study done at Linkoping University using N. Locustae and a central Ethiopian grasshopper species, 55 % of the grasshoppers that were not inoculated reached adulthood, while only 19 % of the ones that were inoculated did. [3]
