Nutrient-Specific Foraging in Invertebrate Predators
TLDR
It is showed experimentally that invertebrate predators can forage selectively for protein and lipids to redress specific nutritional imbalances.
Growth, development, and survival of a generalist predator fed single- and mixed-species diets of different quality
TLDR
The results of these experiments suggest that prey species that are similar in morphology and behavior, and that are initially killed and consumed, may differ dramatically in their suitability as food for generalist arthropod predators.
Optimal foraging for specific nutrients in predatory beetles
TLDR
Female predatory ground beetles (Anchomenus dorsalis) restricted to one of a range of diets varying in lipid and protein content showed that total egg production peaked at a target intake of both nutrients.
The quality of aphids as food for generalist predators: implications for natural control of aphids

TLDR
The low food quality of aphids to generalist predators explains why generalist and specialist predators have widely different roles in aphid biocontrol, but does not rule out that under some conditions the generalists may be able to inhibit aphid population growth sufficiently to prevent an outbreak.
Value of the Aphid Rhopalosiphum padi as Food for Cereal Spiders
TLDR
It was concluded that R. padi represented a low quality prey for cereal spiders which obtain very little energy but essential nutrients from the aphids, and improving availability of alternative prey in more diverse agrosystems may possibly reduce spider predation on aphids.
Effects of prey quality and availability on the life history of a trap-building predator
TLDR
Test the hypothesis that the life history of a trap-building predator is affected by both prey availability and by the nutrient quality of prey to suggest both prey nutrient quality and availability may be important factors shaping the evolution of life history traits in generalist predators.
Factors influencing cannibalism in the wolf spider Pardosa agrestis (Araneae, Lycosidae)
TLDR
The results showed that cannibalism was strongly positively correlated with both weight ratio and hunger, but absolute size/age of an individual could not predict the occurrence of a cannibalistic event.
Behavioral and ecophysiological responses of a generalist predator to single- and mixed-species diets of different quality
TLDR
Consumption by Schizocosa of even small amounts of some “toxic” prey species reduced growth by inhibiting feeding rate and impairing utilization of food derived from prey of higher quality, having implications for understanding the interactions of generalist predators in community food webs.
The value of Collembola from agricultural soils as food for a generalist predator
TLDR
The effect of Collembola quality on the beetle fecundity and larval developmental time suggests that agricultural management for natural enemies, should aim to benefit the species composition of the prey population.
