英文释义

名词 n.
  1. A disease (usually fungal, caused by the species complex Entomophaga grylli) that affects various species of insect, especially grasshoppers, whereby the infected individual typically climbs to the upper parts of a plant, attaches itself there and dies, at which point the infecting agent disperses itself, usually in the form of spores. countable,uncountable
    — Some fungus mediated behavioral changes have been recorded, such as "summit disease" where infected grasshoppers climb to the top of plants to die[…]. This may aid spore dispersal, but it has also been suggested that it is a mechanism by which the host reduces infection through increased exposure to UV.
