Parasites, immunology of hosts, and host sexual selection.

The Journal of parasitology, 1995
Parasite-mediated sexual selection is reviewed with special emphasis on the bird literature. Choosy females may benefit from choosing parasite-free mates if such males provide better parental care, do not transmit contagious parasites, or provide resistance genes to offspring. There is evidence in support of each of these mechanisms.

Parasitism, Host Immune Function, and Sexual Selection

The Quarterly Review of Biology, 1999
Parasite-mediated sexual selection may arise as a consequence of 1) females avoiding mates with directly transmitted parasites, 2) females choosing less-parasitized males that provide parental care of superior quality, or 3) females choosing males with few parasites in order to obtain genes for parasite resistance in their offspring.

Host Selection by Insect Parasitoids

Annual Review of Entomology, 1976
Insects that are parasitic only during their immature stages are termed protelean parasites (11). The protelean parasites that attack invertebrates nearly always de­ stroy their hosts. These parasites are often described as parasitoids, a term coined by Reuter (167) to differentiate them from the typical parasites.

Insect host plant selection in complex environments

Current Opinion in Insect Science, 2015
Selection of suitable host plants is essential for the development and survival of herbivorous insects. Here we address behavioural mechanisms and the role of olfactory cues governing host choice, and their adaptive significance in complicated ecological contexts, with a focus on polyphagous insects.

Host Selection by Mycophagous Drosophila

Ecology, 1978
Host—selection behavior was studied in the mycophagous species, Drosophila falleni, D. putrida, and D. testacea. By marking flies with fluorescent dusts and recapturing them, it was determined that individuals of each of the 3 Drosophila species are attracted to >1 species of mushroom. There appeared to be little variation among individuals in their

Studies on Host Selection and Host Specificity of the Aphid Hyperparasite Charips victrix (Hymenoptera: Cynipidae). 5. Host Selection

Annals of the Entomological Society of America, 1970
Several aspects of host selection by Charips victrix (Westwood) were investigated. The following summarizes the experimental findings: (1) unparasitized aphids were probed but eggs were not deposited in them; (2) parasitized aphids were found readily among unparasitized aphids; (3) unparasitized pea aphids, Acyrthosiphon pisum (Harris), were probed ...

Non-random host selection by anopheline mosquitoes

Parasitology Today, 1988
Malaria represents a complex system. Transmission depends on a multitude of factors - of which vector density may not be the most important (see Box 1). The classical Ross-Macdonald model of malaria transmission (Box 2) reveals two dominant factors: the probability that a mosquito will survive long enough for the parasite to develop to its infective ...

Determination of Host-Selective Toxins

1992
Since Hutchinson’s first toxigenic hypothesis of fungal plant disease, proposed in 1913, there have been many reports of phytotoxins isolated from culture filtrates of pathogens. Some toxins could be related to symptom development, and others were found to have no positive relation to the pathogenicity of the producing fungus.
