Inhibitory Mechanism of Trichoderma virens ZT05 on Rhizoctonia solani

Plants, 2020
Trichoderma is a filamentous fungus that is widely distributed in nature. As a biological control agent of agricultural pests, Trichoderma species have been widely studied in recent years.

International Biological Flora: Loranthus europaeus*

Journal of Ecology, Volume 114, Issue 4, April 2026.
Loranthus europaeus is a deciduous hemiparasitic species native to Europe and western Asia, primarily parasitizing oaks. It forms xylem connections via haustoria, extracting water and nutrients while exhibiting high transpiration and low water‐use efficiency.

First description of conspecific hyperparasitism in Amblyomma sculptum

Ticks and Tick-borne Diseases, 2023
The present study reports a case of conspecific hyperparasitism for Amblyomma sculptum. Two partially engorged females were collected from two naturally infested dairy cows and placed in a single petri dish to be transported to the laboratory, where they were held in a biological oxygen demand (BOD) incubator chamber under controlled conditions of 27 ±

Solving the trophic puzzle: Host–parasite associations in Neotropical fig wasps associated with fig trees of section Americanae

Ecological Entomology, Volume 51, Issue 2, Page 284-294, April 2026.
We determined the trophic associations among fig wasp species associated with Ficus citrifolia by integrating gall morphology, the temporal sequence of wasp colonization, and oviposition behaviour. Dissection of galls produced by four gall‐inducing species at a late developmental phase enabled direct identification of occupants and inference of host ...

Myxosporean hyperparasites of gill monogeneans are basal to the Multivalvulida [PDF]

Parasites & Vectors, 2011
Myxosporeans are known from aquatic annelids but parasitism of platyhelminths by myxosporeans has not been widely reported. Hyperparasitism of gill monogeneans by Myxidium giardi has been reported from the European eel and Myxidium-like hyperparasites have also been observed during studies of gill monogeneans from Malaysia and Japan.The present study ...

Mitogenomic phylogeny of Eurytoma Illiger (Hymenoptera: Eurytomidae): Genus delimitation, species‐group assessment and recurrent host‐use transitions

Systematic Entomology, Volume 51, Issue 2, April‐June 2026.
Mitogenomes from 166 Eurytomidae confirm Eurytoma is polyphyletic; 10 species groups are recovered in Eurytoma s.s., and several lineages are reassigned to other genera or newly delimited clades. Conservative head and mesosoma traits, especially the postgenal depression and ventral shelf, track mitogenomic clades closely, supporting their diagnostic ...

Variations in community assemblages and trophic networks of aphids and parasitoids in protected crops

Ecosphere, 2020
Greenhouse crops are thought to be simplified ecosystems because they often consist of monocultures that are relatively isolated from their environment.

Biotrophic Interactions Between a Mycoparasitic Ampelomyces Fungus and Podosphaera xanthii on Fungicide‐Treated Melon Leaves

Plant Pathology, Volume 75, Issue 2, March/April 2026.
The digital micrographs show images of the infection progress by the mycoparasitic Ampelomyces strain in a melon powdery mildew fungus Podosphaera xanthii that was treated with kresoxim‐methyl and sprayed with Ampelomyces spores under the high‐humidity conditions of a growth chamber.

Molecular Data Confirm Interspecific Limits of Four Alloxysta and One Phaenoglyphis Species of Parasitic Wasps within the Subfamily Charipinae (Cynipoidea: Figitidae)

Insects
The hymenopteran subfamily Charipinae (Cynipoidea: Figitidae) consist of a group of parasitic wasps that are exclusive hyperparasitoids of Hemipteran. The species boundaries in Charipinae have historically been unclear.

The role of hyperparasitism in microbial pathogen ecology and evolution [PDF]

The ISME Journal, 2016
Abstract Many micro-organisms employ a parasitic lifestyle and, through their antagonistic interactions with host populations, have major impacts on human, agricultural and natural ecosystems. Most pathogens are likely to host parasites of their own, that is, hyperparasites, but how nested chains of parasites impact on disease dynamics ...
