The evolution of defensive traits and strategies depends on the intensity of selection
imposed by natural enemies and on the fitness costs of defenses against these enemies. We …

Plants use a diverse mix of defenses against herbivores, including multiple secondary
metabolites, which may affect herbivores synergistically. Chemical defenses also can affect …

We investigated the life history consequences of changes in diet between larval and adult
life stages in the polyphagous lady beetle Coleomegilla maculata DeGeer (Coleoptera …

Sequestration of plant compounds by herbivorous insects as a defense against predators is
well documented; however, few studies have examined the effectiveness of sequestration as …

Invasive plant species can have significant ecological and economic impacts. Although
numerous hypotheses highlight the importance of the chemical defenses of invasive plant …

M onarch larvae are specialists on milkweed (Asclepias spp.) host plants. Milkweeds|
produce cardenolides, which are bitter, toxic, and effective deterrents for many herbivores …

The diet breadth of insect herbivores influences their response to variation in plant quality,
and these bitrophic interactions have implications for the higher‐level trophic interactions …

Estimation of the host range of entomophagous biological control agents (parasitoids and
predators) is more complex than for phytophagous weed biological control agents. This is …

Larvae of Epargyreus clarus (Hesperiidae), the silver-spotted skipper, inhabit leaf-and-silk
shelters that they construct on their leguminous host plants. In the field, Polistes …

Many insect herbivores are dietary specialists capable of sequestering the secondary
metabolites produced by their host plants. These defensive compounds have important but …
