SummaryAn indirect effects is defined here as a reduction in prey survivorship as a consequence of a reduction in growth rate of prey due to the presence of a predator that alters prey behavior. A method for partitioning the direct and indirect effects of predators on prey survivorship indicated that predatory wasps (Polistes sp.:. Vespidae) had both direct and indirect negative effects on survivorship of buckmoth caterpillars (Hemileuca lucina: Saturniidae). In a field experiment, the direct…

Resource-mediated impact of spider predation risk on performance in the grasshopper Ageneotettix deorum (Orthoptera: Acrididae)

Increased resource quality can clearly moderate the negative life history responses caused by the behavioral modification of grasshoppers when exposed to spider predation risk, a compensatory response.

Direct and indirect effect of cannibalism and intraguild predation in the two sibling Harmonia ladybird beetles

Different behaviors in the direct and indirect effects of cannibalism and IGP observed in the laboratory may play important roles in the coexistence of generalist–common H. axyridis and specialist–rare H. yedoensis in natural conditions.

Relative susceptibility to predation of two species of caterpillar on plantain

It is indicated that Spilosoma caterpillars, by way of cryptic and escape behaviors, can be less susceptible to insect predators than Junonia caterpillar.

Predator Cues Increase Silkmoth Mortality

The results of two separate experiments assessing the responses of Actias larvae to predatory wasps are reported, illustrating the high cost of anti-predator responses and are the first report of lethal risk effects in caterpillars.

Do Enemies of Herbivores Influence Plant Growth and Chemistry? Evidence from a Seminatural Experiment

The lack of effect by predators seems to reflect the relatively large variation in iridoid glycoside concentration among leaf ages, and the herbivores ability to respond to that variation, such that the difference in iriridoid Glycoside concentrations in the plant genotypes was less important.

N onlethal Effects in the Ecology of Predator-Prey Interactions

P redator-prey interactions have long captured the attention of ecologists, and with good reason. Predation leads inevitably to the removal of prey individuals from ecological systems, which can have…

Presence of predatory wasps and stinkbugs alters foraging behavior of cryptic and non-cryptic caterpillars on plantain (Plantago lanceolata)

It is found that both the amount of leaves eaten and the proportion of plants eaten were altered on plots with predators present, which suggests that the caterpillars' increased consumption countered increased maintenance costs due to the presence of predators.

Foraging behavior of specialist and generalist caterpillars on plantain (Plantago lanceolata) altered by predatory stinkbugs

The stinkbugs reduced the survivorship of the specialist caterpillars but not that of the generalists, which reflects the differences in predatoravoidance behaviors of these species.

Predator Presence Moves Helicoverpa armigera Larvae to Distraction

It is shown how the mere presence of the predator, Geocoris lubra Kirkaldy, on a plant can have a strong influence on the movement and behaviors of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) larvae.

Effects of large Saduria entomon (Isopoda) on spatial distribution of their small S. entomon and Monoporeia affinis (Amphipoda) prey

The combined effect of avoidance behaviour and predation in both species was aggregation, producting a positive correlation between the species in density.

Direct and indirect effects of predatory wasps (Polistes sp.: Vespidae) on gregarious caterpillars (Hemileuca lucina: Saturniidae)

It is suggested that wasps, in addition to killing caterpillars, indirectly affect larval fitness by slowing larval growth, at least in part by forcing larvae into cooler microhabitats where leaves are of lower quality.

The costs of reduced feeding due to predator avoidance: potential effects on growth and fitness in Ischnura elegans larvae (Odonata: Zygoptera)

Calculations made from published data show that reduced larval feeding rates can lead to slower growth and development and prolonged instar durations in Ischnura elegans larvae, which may have important consequences for larval survival and adult reproductive fitness.

The Effect of Predator Age and Prey Defense on the Functional Response of Podisus maculiventris Say to the Density of Hyphantria cunea Drury

It is concluded that the functional response of the various predators inside the nest is probably not important, and that attention should be devoted instead to the functional and numerical responses of predators and parasites to the density of nests per unit area.

It is concluded that the influence of the nest-inhabiting predators is small and relatively stable, and may be treated as a constant in the development of models to explain the population dynamics of H .

PHYSICAL CONSTRAINTS OF DEFENSE AND RESPONSE TO INVERTEBRATE PREDATORS BY PIPEVINE CATERPILLARS BATTUS-PHILENOR PAPILIONIDAE

The responses of pipevine swallowtail caterpillars to simulated attacks of invertebrate enemies and to actual attack by coccinel\id larvae were examined and it was shown that they were more reactive to the simulated attack of a biting predator than to the simulate touch by an insect enemy.

Foraging strategies of caterpillars

It is concluded that some caterpillar foraging behaviors may have evolved under the selective pressure of visually-oriented predators that use leaf-damage as a cue in their searching behavior.

Developmental change in aggregation, defense and escape behavior of buckmoth caterpillars, Hemileuca lucina (Saturniidae)

As larvae developed, the change from predominantly defense to escape behaviors paralleled the decline in tendency to aggregate.

CHERRIES, ANTS AND TENT CATERPILLARS: TIMING OF NECTAR PRODUCTION IN RELATION TO SUSCEPTIBILITY OF CATERPILLARS TO ANT PREDATION1

It is suggested that the ant-cherry relationship is a facultative mutualism and that nectar production is timed so as to maximize the chance of successful ant predation on tent-caterpillar colonies.

Foraging Strategies and the Avoidance of Predation by an Aquatic Insect, Notonecta Hoffmanni

The degree of avoidance is related to the risk of predation and the possibility that feeding behavior represents an adaptive compromise between the conflicting demands of feeding efficiently and avoiding predators is discussed, and the effects on the predictions of optimal foraging theory of some common mecha- nisms by which notonectids avoid their predators are discussed.

Cherries, Ants and Tent Caterpillars: Timing of Nectar Production in Relation in Relation to Susceptibility of Catepillars to Ant Predation

It is suggested that the ant—cherry relationship is a faculative mutualism and that nectar production is timed so as to maximize the chance of successful ant predation on tent—caterpillar colonies.
