Ecology Letters (2010) 13: 383–393 Abstract The extent to which behavioural choices reflect
fine‐tuned evolutionary adaptation remains an open debate. For herbivorous insects, the …

Among herbivorous insects with a complete metamorphosis the larval and adult stages
usually differ considerably in their nutritional requirements and food ecology. Often, feeding …

Novel methodology is presented for indexing the relative potential of hosts to function as
resources. A Host Potential Index (HPI) was developed as a practical framework to express …

Abstract Heliothine moths (Lepidoptera: Heliothinae) include some of the world's most
devastating pest species. Whereas the majority of nonpest heliothinae specialize on a single …

“Pests soon colonize plants that are cultivated extensively, plant species recruit different pest
species in different regions, and associations of insects with plants are often more casual …

There is a considerable interest in trying to understand how aphids find their host plants
because they are a major cause of economic losses in agricultural and horticultural …

Highlights•Insect herbivores deal with a vast spectrum of information from many
sources.•Limitations in host plant choice accuracy in polyphagous insects may be mitigated …

Oviposition substrate selection, egg mass characteristics, host preference, and life history of
Lycorma delicatula (White)(Hemiptera: Fulgoridae) were studied in Pennsylvania between …

Insect olfactory orientation along odour plumes has been studied intensively with respect to
pheromonal communication, whereas little knowledge is available on how plant odour …

Kairomones are chemical signals that mediate interspecific interactions beneficial to
organisms that detect the cues. These attractants can be individual compounds or mixtures …
