Some experiments were carried out on this subject with some of the common grasshoppers. Fungous diseases of adult grasshoppers can be ignored, for in normal years the percentage of infestation is very low, probably less than one per cent. All control insects survived the 9-day period of observation, while 30-95% of parasitized grasshoppers died, depending on the species (table 1).

Furthermore, the different strategy adaptations of this insular grasshopper were compared with related continental species. The present studies were carried out in order to find out the potential and actual fertilities of grasshoppers, and to determine their role in outbreaks.
