   [page 22] Among the most illuminating and certainly the most bizarre of self-replicators are the digital organisms invented by Thomas Ray of the University of Delaware. [...] [page 23] A peculiar creature that is 80 instructions long, but differs from the ancestral sequence by 20 or so alterations, has sometimes been observed; it is a hyperparasite able to force parasites to replace themselves with copies of itself.

   In a second instance, two parasitic fungi (Dicyma pulvinata and Cylindrosporium concentricum) were introduced against a fungal pathogen causing black crust on the foliage of rubber, Phyllachora huberi, in the Amazon basin of Brazil and long-term control was documented [...]. These antagonists are obligate pathogens living as hyperparasites and their increase is dependent on the presence of the plant pathogen.

   Secondary parasites, or hyperparasites, are parasites of primary parasites and have quite the opposite ecological effect since they constrain the population of the primary parasite. [...] A few species are able to function as facultative hyperparasites, attacking both the host and its primary parasites.
