Entomophaga grylli : ウィキペディア英語版 | Entomophaga grylli
''Entomophaga grylli'' is a fungal pathogen which infects and kills grasshoppers. It is the causal agent of one of the most widespread diseases affecting grasshoppers. This is sometimes known as summit disease because infected insects climb to the upper part of a plant and grip the tip of the stem as they die; this ensures widespread dispersal of the fungal spores.〔 The fungus is a species complex with several different pathotypes, each one of which seems to be host-specific to different subfamilies of grasshoppers. The pathogen is being investigated for its possible use in biological pest control of grasshoppers. ==Taxonomy== ''E. grylli'' is a species complex which in North America includes the pathotypes ''E. macleodii'' and ''E. calopteni'', and in Australia ''E. praxibuli''. The different pathotypes can be distinguished by the formation or lack of formation of primary conidia, the size and the number of nuclei in the conidia, their isozyme profiles, the host species involved, and the geographical range in which they are found. They all attack grasshoppers, but it is not known whether all grasshopper species are susceptible to infection. Each pathotype seems to be host-specific to certain grasshopper subfamilies.
