An endoparasitoid avoids hyperparasitism by manipulating immobile host herbivore to modify host plant morphology. [PDF]

open access: yesPLoS ONE, 2014
Many parasitic organisms have an ability to manipulate their hosts to increase their own fitness. In parasitoids, behavioral changes of mobile hosts to avoid or protect against predation and hyperparasitism have been intensively studied, but host ...

Ecological functions of zoosporic hyperparasites

open access: yesFrontiers in Microbiology, 2014
Zoosporic parasites have received increased attention during the last years, but it is still largely unnoted that these parasites can themselves be infected by hyperparasites. Some members of the Chytridiomycota, Blastocladiomycota, Cryptomycota, Hyphochytriomycota, Labyrinthulomycota, Oomycota, and Phytomyxea are hyperparasites of zoosporic hosts ...

Antifungal activity of microbiological drugs in relation to pathogens from the genus Fusarium Link

open access: yesBIO Web of Conferences, 2021
As a result of studying the antifungal activity of biological drugs against fungi of the genus Fusarium, causative agents of rot of roots and fruits of the apple tree, both weak and very strong mycoparasitism were noted, but in most variants of the ...
