Habitat selection when killing primary versus alternative prey species supports prey specialization in an apex predator [PDF]

, 2019
© 2019 The Zoological Society of London Many predators specialize on one or several prey species that they select from the range of potential prey. Predator specialization on primary versus alternative prey is driven in part by encounter rates with prey ...

The two spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), alternative prey for the lacewing Dichochrysa prasina (Neuroptera: Chrysopidae)

European Journal of Entomology, 2008
The predatory lacewing Dichochrysa prasina Burmeister can feed and reproduce on various aphid species. However, other species such as the two spotted spider mite Tetranychus urticae Koch may serve as an alternative prey for this predator in the field in ...

Numbers, neighbors, and hungry predators: What makes chemically defended aposematic prey susceptible to predation?

Ecology and Evolution, 2020
Many chemically defended aposematic species are characterized by relatively low toxin levels, which enables predators to include them in their diets under certain circumstances.

The effects of six species of aphids on some life history parameters of the ladybird Propylea quatuordecimpunctata (Coleoptera: Coccinellidae)

European Journal of Entomology, 2005
One of the factors affecting the effectiveness of predatory coccinellids in an aphid infested crop is the food specificity of the predator. The response towards six species of aphids (Sternorrhyncha: Aphididae) was therefore tested in one of the most ...

Optimal-foraging predator favors commensalistic Batesian mimicry. [PDF]

PLoS ONE, 2008
BACKGROUND:Mimicry, in which one prey species (the Mimic) imitates the aposematic signals of another prey (the Model) to deceive their predators, has attracted the general interest of evolutionary biologists.

Predator discrimination of prey promotes the predator-mediated coexistence of prey species

Royal Society Open Science, 2022
The predator discrimination of prey can affect predation intensity and the prey density dependence of predators, which has the potential to alter the coexistence of prey species.

THE EFFECT OF ALTERNATIVE PREY ON THE DYNAMICS OF IMPERFECT BATESIAN AND MÜLLERIAN MIMICRIES [PDF]

Evolution, 2004
Both Batesian and Müllerian mimicries are considered classical evidence of natural selection where predation pressure has, at times, created a striking similarity between unrelated prey species. Batesian mimicry, in which palatable mimics resemble unpalatable aposematic species, is parasitic and only beneficial to the mimics.

Reproduction and longevity of Supputius cincticeps (Het.: Pentatomidae) fed with larvae of Zophobas confusa, Tenebrio molitor (Col.: Tenebrionidae) or Musca domestica (Dip.: Muscidae)

Brazilian Archives of Biology and Technology, 2005
Reproduction and longevity of Supputius cincticeps (Stål) (Heteroptera: Pentatomidae) fed on Zophobas confusa Gebien, Tenebrio molitor L. (Coleoptera: Tenebrionidae) or Musca domestica (L.) (Diptera: Muscidae) larvae were studied during two generations ...

A simple predator–prey model of exploited marine fish populations incorporating alternative prey [PDF]

ICES Journal of Marine Science, 1996
A simple two-species population model in which the predator is partially coupled to the prey is developed. The model is an extension of traditional two-species models but less complex than a three-species system. The growth rate of the predator depends upon predation on the modeled and alternate prey; this formulation provides greater realism in ...
