A new species and genus of entomophthoralean fungus, Arthrophaga myriapodina kills polydesmid millipedes. This species was first seen over a century ago but never described. It is the first millipede pathogen known from the order Entomophthorales, species of which are best known as pathogens of a wide diversity of insects. The fungus induces pre-death climbing behavior in its hosts, enabling the fungus to broadcast its forcibly-discharged conidia from a high vantage, which presumably increases the fitness of the fungus. Study of herbarium specimens and photographic discoveries on the internet suggest the fungus occurs widely in eastern North America.
一种新的昆虫真菌，节虫霉属的节虫霉，可杀死倍足纲千足虫。该物种一个多世纪前就已被发现，但从未被描述过。它是已知的第一个来自昆虫纲的千足虫病原体，而该纲的物种最常见的是作为各种昆虫的病原体。这种真菌会诱导其宿主在死前进行攀爬行为，使真菌能够从高处将其强制排出的分生孢子散布出去，这可能会增加真菌的适应性。对标本和互联网上的照片的研究表明，这种真菌广泛存在于北美东部。
