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 This review points out the problem of processing multiple sensory inputs and
provides evidence that generalists suffer a disadvantage compared with specialists with …

The current concepts of host plant resistance to insects are reviewed in this book. The broad
coverage includes crop plant and insect diversity, mechanisms of insect-plant interactions …

Literature data were collected on the floristic distribution and toxicity of phytochemicals to
herbivores and on herbivore specialization in order to test phytochemical coevolution theory …

Specializing on host plants with toxic secondary compounds enforces specific adaptation in
insect herbivores. In this review, we focus on two compound classes, iridoid glycosides and …

In reviewing the hostplant associations of nymphalid butterflies, particular emphasis is
placed on the intractable problem of nymphalid classification. Although offering few certain …

Populations of wild Brassica oleracea L. grow naturally along the Atlantic coastlines of the
United Kingdom and France. Over a very small spatial scale (ie,< 15 km) these populations …

Plant performance and chemistry may vary due to a variety of factors, such as plant
genotype, environmental conditions, presence of herbivores, timing of herbivory, and …

Dogwoods evolved in two main lineages, a red-fruited line in which the inflorescences have
basal bracts, and a blue-(or white-) fruited line in which the bracts are rudimentary or …

We examined the effects of a set of four biosynthetically related iridoid glycosides, aucubin,
catalpol, loganin, and asperuloside, on larvae of a generalist, Lymantria dispar …
