Insects are by far the most diverse group of organisms on Earth; estimates of their current
diversity range as high as 30 million species (58). A large fraction of these species feed on …

▪ Abstract Herbivore offense describes traits that allow herbivores to increase their feeding
and other uses of host plants when these uses benefit the herbivores. We argue that …

Populations and communities of organisms are influenced by a host of abiotic and biotic
factors. Climate, nutrients, natural enemies (including parasites and pathogens), symbionts …

Four sources of evidence are used to support the Plant Vigor Hypothesis that many
herbivore species feed preferentially on vigorous plants or plant modules, as opposed to the …

Biologists who study insect-induced plant galls are faced with the overwhelming diversity of
plant forms and insect species. A challenge is to find common themes amidst this diversity …

To investigate the relationship between oviposition preference and offspring performance
we tested three hypotheses about the oviposition behavior of Euura lasiolepis:(1) the …

Gall forming herbivores induce sinks and act as phloem parasites within their host plants.
Their performance on the host plant can depend on the sink-source relationship they …

An understanding of the dynamics of populations is critically important to ecologists,
evolutionary biologists, wildlife managers, foresters, and many other biologists. This edited …

Among Lepidoptera, populations of some species display outbreaks at irregular intervals,
some show regular cycles, whereas densities of most species never reach extremely high …

Potential fecundity of Epirrita autumnata females is strongly correlated with pupal weight.
Adult feeding weakly increases fecundity but does not eliminate its dependence on body …
