Hyperparasitism in Ornithodoros erraticus
The Journal of Parasitology, 1983Hyperparasitism is common in laboratory colonies of Egyptian Ornithodoros erraticus whether the ticks are on or off the rodent host. Sex, recent engorgement, and size appear to be major factors in this feeding relationship. Males, and nymphs that produced males (N-male), parasitized females and nymphs that produced females (N-female) more frequently ...

Revisiting the Role of Hyperparasitism in the Evolution of Virulence
The American Naturalist, 2021AbstractHyperparasitism denotes the natural phenomenon where a parasite infecting a host is in turn infected by its own parasite. Hyperparasites can shape the dynamics of host-parasite interactions and often have a deleterious impact on pathogens, an important class of parasites, causing a reduction in their virulence and transmission rate ...

Annual Review of Phytopathology, 1964
Much of the research on hyperparasitism has been of a descriptive nature, based primarily on studies with dual cultures in synthetic media. The main contributions from these investigations concern the host range of the parasite, the mode of penetration and infection, and the morphological changes of the host and the parasite resulting from parasitism ...

Mycologia, 1969
A new species of Blyttiomyces, B. rhizophlyctidis, is described and discussed. It is readily distinguished from all other previously known species of the genus by its angular or tubercular sporangi...

A Model for Hyperparasitism in Malaria With Environmental Fluctuations
Applied Mathematics and Computation, 2009The present paper deals with the problem of enhancement of host fitness in malaria, due to the effect of hyperparasitism. The experimental evidence for such situations is reviewed. A mathematical model for host-parasite-parasitoid (tritrophic) is considered to analyze the experimental observations.

HYPERPARASITISM: Multitrophic Ecology and Behavior
Annual Review of Entomology, 1999▪ Abstract Hyperparasitoids are secondary insect parasitoids that develop at the expense of a primary parasitoid, thereby representing a highly evolved fourth trophic level. This review evaluates multitrophic relationships and hyperparasitoid ecology.

Hyperparasitism of Mosquitoes by Water Mite Larvae
Parasitology Research, 2015Hyperparasitism of ectoparasitic water mite larvae on mosquitoes is still a neglected relationship and was investigated only in a few studies. We analysed 2313 female mosquitoes from six different sampling localities with regard to their degree of parasitism with water mite larvae. In total, we found 38 mosquito individuals parasitized by 93 water mite

The Quarterly Review of Biology, 1934
T H E interrelations among organisms in nature are wonderfully diverse. Symbiosis-the association of organisms for their mutual advantage; and parasitism-the existence of one organism at the expense of another-are two opposite extremes of the same phenomenon. Parasitism has attracted much attention. Among plants and animals parasites are very numerous.
