Why Are Cuckoos Host Specific?

Oikos, 1990
Evidence suggests that each cuckoo species is specific to a discrete group of primary hosts, although there is often considerable overlap in the use of secondary hosts. Presumably therefore, the host segregation of cuckoo species has evolved as a result of interspecific competition, in line with Gause's hypothesis.

The host specificity of monogenetic trematodes

Experimental Parasitology, 1957
Abstract The host-parasite relations of the 75 species of Monogenea in the present collection and many more from the literature have been considered and the following conclusions reached: 1. 1. The species studied, and probably most other Monogenea, are highly host-specific. 2. 2.

Host specificity and speciation

1985
Most aphids are autoecious (Figure 3.1), living on one or a few species of a particular genus of plants (Eastop, 1973). About 10% are heteroecious (Figure 3.1), spending autumn, winter and spring on a primary host plant, and the summer on a secondary host plant(s), which is rarely closely related to the primary host. For example the primary host of the

Host Specificity of Plant Viruses

Annual Review of Phytopathology, 1975
What factors determine the host specificity of viruses? This is not a simple question and a simple answer is not expected. More often than not we do not know which features of the host and the virus are responsible for the tendency of a plant cell to resist or be susceptible to infection.

[Host specificity of homoxenous trypanosomatids].

Parazitologiia, 2003
Some problems in a correct using of the term "host specificity" for parasitic protozoans and specifically for the trypanosomatids are discussed. Results of investigation the host specificity of the trypanosomatids obtained by traditional methods are summarized.
