1. The effects of prey species and leaf age used by prey on performance of two generalist invertebrate predators were studied. The focal plant was Plantago lanceolata, which contains iridoid glycosides. 

Effects of prey quantity and quality on predatory wasps

1. The simultaneous effects of prey quantity and prey quality on fitness correlates of the predatory wasp Polistes fuscatus were examined in a glasshouse study. Prey quantity was manipulated by

Prey identity but not prey quality affects spider performance

Using food for different purposes: female responses to prey in the predator Coccinella septempunctata L. (Coleoptera: Coccinellidae)

The propensity of adult females of the ladybird beetle to attack two natural prey species, pea aphids and alfalfa weevil larvae, was compared, and the degree to which ladybird egg production depends on consumption of aphids vs. weevils was assessed.

Interactions between a hunting spider and a web‐builder: consequences of intraguild predation and cannibalism for prey suppression

Two abundant spider predators, the large wolf spider Pardosa littoralis and the small sheet‐web builder Grammonota trivitatta co‐occur on the salt marshes of eastern North America where they both attack planthoppers, the dominant herbivores on the marsh.

Investigating the Relationship Between Dietary Specialization of Caterpillars and Their Risk of Ant Predation in a Forest Community

The risk of predation by ants is quantified for a community of caterpillar species that employ several putative anti-predator traits that may be constrained by dietary specialization and their correlation with diet breadth in a temperate forest.

Effects of prey quality on social wasps when given a choice of prey

The effect of prey quality on foraging behavior and colony demographics of the social wasp Polistes fuscatus was examined by providing a choice between non‐toxic prey and sublethally toxic prey, and then comparing the performance of these colonies to others given only the non‐Toxic prey.

Combined effects of allelochemicals, prey availability, and supplemental plant material on growth of a generalist insect predator

Overall, there was no negative effect of allelochemicals in the diet of the prey on these variables when predators were supplied with an excess of prey, but alle Loclochemical in the prey diet negatively affected these predators when prey were scarce.


In general, body nitrogen content increased and C:N ratio decreased from lower to higher trophic levels for marsh-inhabiting arthropods, suggesting that many predators may be nitrogen limited, and intraguild predation may allow them to increase their nitrogen intake and growth by supplementing a diet of herbivores with more nitrogen-rich intrusion prey.

Combined effects of allelochemical‐fed and scarce prey on the generalist insect predator Podisusmaculiventris

1. The simultaneous effects of allelochemicals ingested by herbivorous insect prey and prey scarcity on the performance of a generalist insect predator were examined.

On the Evolution of Host Specificity in Phytophagous Arthropods

We argue that generalist natural enemies of herbivorous insects provide a major selection pressure for restricted host plant range. The significance of plant chemistry is discussed in terms of

Growth of Herbivorous Caterpillars in Relation to Feeding Specialization and to the Growth Form of Their Food Plants

A clear relationship between larval growth and growth form of the food plants quantified as leaf water content was revealed, and it was found that larvae grew faster and more efficiently on herbaceous plants than on the foliage of shrubs and trees.


Abstract Reproductive and survival patterns of the heteropteran predator Podisus maculiventris (Say) (Heteroptera: Pentatomidae) were measured under low prey inputs. A single prey, mealworm larva

Effects of chlorogenic acid- and tomatine-fed caterpillars on performance of an insect predator

The hypothesis that generalist insect predators may be a selective pressure shaping host plant range of insect herbivores was supported and the occurrence of allelochemical by thermal regime interactions means that it will be difficult to determine the relative importance of plant chemistry versus predators on patterns of feeding specialization by herbivore without taking into account a third factor, temperature.

Plant apparency and chemical defense

A test of how far understanding of insect ecology has progressed will be the authors' ability to predict how patterns vary from one kind of community to another and how they will change when subjected to natural or human disturbance.

Host specificity in phytophagous insects: selection pressure from generalist predators

Experiments to test the hypothesis that generalists are more vulnerable than specialists to predators are described, and generalists were taken more readily than specialists: some but not all reasons could be detected.

Food Limitation of the Spider Linyphia marginata: Experimental Field Studies

It appears that mature L. marginate compete for food; hence, for them, food supply acts as a density-dependent limiting factor, and that though a shortage of food limits growth, immature spiders are not competing for food.

Insect Hosts and Nymphal Development of Podisus Maculiventris Say and Perillus Bioculatus F. (Hemiptera, Pentatomidae)

This study highlights the importance of knowing the larva-to-fly ratio, as a source of infection for honey bees, which can be a clue to the presence of sexually transmitted diseases.

Tasty Generalists and Nasty Specialists? Antipredator Mechanisms in Tropical Lepidopteran Larvae

It is concluded that predation could be a substantial selective force in the evolution of narrow diet breadth and that plant chemistry could be the mechanism whereby specialists are better defended.
