Prey-specialised spiders often do not have brood care and may not deposit eggs in the proximity of the preferred prey. Thus, naïve spiderlings are left to their own to find their focal prey. Our aim was to reveal whether the choice of a specific prey is innate and whether familiarisation with a certain prey will condition prey choice.

Abstract In specialized predators, a variety of adaptations have evolved to such a level of specificity that they allow very effective exploitation of focal prey. Venom is an essential adaptive trait of predatory venomous species, such as spiders, yet our knowledge of spider venom is incomplete.

Serangium parcesetosum Sicard (Col., Coccinellidae) is considered one of the important predators of whiteflies. However, knowledge about its preferences for different prey stages, species and parasitized prey is still lacking in the literature. The present work investigated the preferences of S. parcesetosum for different stages of B. tabaci, different

Prey preference by Metaseiulus occidentalis (Acari: Phytoseiidae) and the role of prey aggregation
Biological Control, 1991Abstract The phytoseiid predator Metaseiulus occidentalis is an important biological control agent for the Pacific spider mite (PSM) Tetranychus pacificus and the Willamette spider mite (WSM) Eotetranychus willamettei, two economically important spider mite species in California vineyards. Field observations indicated that M.

Prey Preference in Stethorus punctum (Coleoptera: Coccinellidae)
Environmental Entomology, 1986Stethorus punctum (LeConte) is an obligate predator of tetranychid mites. Laboratory studies were conducted to determine feeding preference of S. punctum at varying densities of Panonychus ulmi (Koch) and Tetranychus urticae Koch. Using the Strauss linear index of prey selection, S.

Hunger, partial consumption of prey and prey size preference in a carabid beetle
Ecological Entomology, 1988ABSTRACT. Partial consumption of prey and prey size preference were studied in females of the carabid Notiophilus biguttatus F., using different size‐classes of the springtail

Grasshopper Coloration Influences Juvenile Collared Lizard Prey Preference
The Southwestern Naturalist, 2019We tested the influence of grasshopper coloration on the foraging preferences of juvenile collared lizards (Crotaphytus collaris) that prey on grasshoppers. The study site harbored three grasshopper species with coloration that varied considerably: Melanoplus differentialis (yellow), Syrbula admirabilis (green), and Ageneotettix deorum (brown).

Ecology, 2019
AbstractIndividual diet specialization appears widespread and has several ecological ramifications. Hypotheses on the causes of diet specialization generally assume prey preferences differ among predator individuals. They then predict how the magnitude of diet variation should change when ecological factors (e.g., intraspecific competition) alter prey ...

Initial Prey Preferences in the Lizard Sceloporus malachiticus
Copeia, 1981Neonate and inexperienced Sceloporus malachiticus (Squamata: Iguanidae) have an unlearned response to the aposematic color pattern of the milkweed bug Oncopeltus fasciatus. This response may be interpreted as either an avoidance of the aposematic color pattern or a preference for the uniformly colored alternate prey.
