Microfungi in the phyllosphere of Senecio umbrosus Waldst. et Kit., a host species with a narrow ecological niche

Acta Mycologica, 2023
Among the biotic factors that limit plant growth, population size, and reproduction, there is a mass appearance of microscopic parasitic fungi. The aim of the study was to determine the spectrum of the microfungi and the degree of leaf surface infection ...

Hyperparasitism in a Generalist Ectoparasitic Pupal Parasitoid, Pachycrepoideus vindemmiae (Hymenoptera: Pteromalidae), on Its Own Conspecifics: When the Lack of Resource Lead to Cannibalism.

PLoS ONE, 2015
Hyperparasitism is a normal behavior of parasitoids, which often happens among species. Conspecific hyperparasitism, such as some kinds of heteronomous hyperparasitic behaviors, has been only reported in some species belonging to Aphelinidae.
