Induced defense mechanisms in an aquatic angiosperm to insect herbivory
Oecologia, 2014In terrestrial angiosperms, defense and resistance mechanisms against herbivores have been studied extensively; yet this topic is poorly understood in aquatic angiosperms. We investigated induced response mechanisms in Myriophyllum spicatum to the generalist insect herbivore Acentria ephemerella in three independent experiments.

Insect herbivory and non-woody plants
1982Herbaceous plants are usually relatively short-lived and lack the resistant structural materials found in the woody plants. Thus, the whole plant is potentially susceptible to insect herbivory. Much of the literature dealing with the effects of insects on such plants relates to agricultural crops and there is little detailed information on noneconomic ...

Reassessment of the role of gut alkalinity and detergency in insect herbivory
Journal of Chemical Ecology, 1991Previously it was reported that significant amounts of the tomato phenolic, chlorogenic acid, were oxidized in the digestive system of generalist feedersSpodoplera exigua andHelicoverpa zea. The covalent binding of the oxidized phenolic (i.e., quinone) to dietary protein exerts a strong antinutritive effect against larvae.

Effects of insect herbivory on plant architecture
1994In plants of Mediterranean-type ecosystems, the diversity and distribution of construction units or modules of species may lead to an enhanced understanding of specific types of metameric architecture and thus of canopy construction. An analysis of 160 species of plants from ecosystems of central Chile, France, Israel and South Africa resulted in the ...

Physiological Adaptations of the Insect Gut to Herbivory
2012Plant biomass is the most abundant resource in terrestrial communities, and terrestrial green plants and the herbivorous (phytophagous) insects that feed on them account for more than half of all living species (Scudder 2009). Still, herbivory appears to have represented a challenge that most insect orders have not been able to adapt, since ...

Insect Herbivores, Herbivory and Plant Succession
1990Succession is a characteristic feature of most plant communities and is clearly seen when any habitat is disturbed. The temporal and directional changes in plant communities, which constitute succession, are well documented and have been described in a range of different habitats and geographical regions (e.g.
