Agricultural intensification and greater production of Brassica vegetable and oilseed crops
over the past two decades have increased the pest status of the diamondback moth (DBM) …

There has been a long-standing hypothesis that specialist and generalist insects interact
with plants in distinct ways. Although many tests exist, they typically compare only one …

Increased frequency and severity of drought, as a result of climate change, is expected to
drive critical changes in plant–insect interactions that may elevate rates of tree mortality. The …

Background Plants are hotbeds for parasites such as arthropod herbivores, which acquire
nutrients and energy from their hosts in order to grow and reproduce. Hence plants are …

Plants release volatiles induced by herbivore feeding that may affect the diversity and
composition of plant-associated arthropod communities. However, the specificity and role of …

Glucosinolates are token stimuli in host selection of many crucifer specialist insects, but the
underlying molecular basis for host selection in these insects remains enigmatic. Using a …

Induction of plant defences by early season herbivores can mediate interspecific herbivore
competition. We have investigated plant‐mediated competition between three herbivorous …

Intraspecific variation in plants plays a major role in the composition and diversity of the
associated insect community. Resistance traits of plants are likely candidates mediating …

A general prediction of the specialist/generalist paradigm indicates that plant responses to
insect herbivores may depend on the degree of ecological specialization of the insect …

Winter cress (Barbarea vulgaris) is resistant to a range of insect species. Some B. vulgaris
genotypes are resistant, whereas others are susceptible, to herbivory by flea beetle larvae …
