Insect herbivory and woody plants

1982
Wood is persistent and woody plants may live to a great age. An important reason for this is that relatively few insects have evolved to exploit wood in living plants. Most species feed on the softer and more transient tissues of woody plants such as leaves, fine roots, flowers, fruits and to a lesser extent the meristems.

Tree diversity reduces herbivory by forest insects

Ecology Letters, 2007
AbstractBiodiversity loss from plant communities is often acknowledged to affect primary production but little is known about effects on herbivores. We conducted a meta‐analysis of a worldwide data set of 119 studies to compare herbivory in single‐species and mixed forests.

Insect herbivory and the plant community

1982
In this chapter we will examine how plant communities can modify, either directly or indirectly, the abundance and population dynamics of their associated insect herbivores and, conversely, how insect herbivores might alter the composition of plant communities [163].

Insect herbivory fluctuations through geological time

Ecology, 2016
AbstractArthropods and land plants are the major macroscopic sources of biodiversity on the planet. Knowledge of the organization and specialization of plant–herbivore interactions, such as their roles in food webs is important for understanding the processes for maintaining biodiversity.

Insect herbivory on an inland brackish wetland

Wetlands, 1988
Standing crop measurements were made in emergent wetland vegetation following acute herbivory by 2 species of leaf-chewing caterpillars,Cisseps fulvicula (Ctenucidae) andAcronicta leporina (Noctuidae). Significant weight differences were found between grazed and ungrazed stands of alkali bulrush, cattail, Olney’s bulrush, and saltgrass, respectively ...

Intercropping Alters Phytochemicals Associated With Insect Herbivory

Journal of Chemical Ecology
Given the multiple possible mechanisms for interspecific chemical interaction between adjacent heterospecific plants, phytochemical profiles, which include phytochemical defense compounds, of crop species could potentially be enhanced or altered by intercropping with phytochemically diverse neighbors.

Background Insect Herbivory: Impacts, Patterns and Methodology

2017
Plants provide humans with oxygen, food, fibre and fuel, but their effectiveness in performing these roles is affected by herbivores. Historically, studies on insect herbivory have primarily addressed pest outbreaks, which have indisputable ecological and economic consequences.

Plant Resistance to Insect Herbivory

2011
Plants are the major food source for most insects. While insects have developed various feeding strategies, plants respond by activating distinct signaling pathways resulting in the production of defensive compounds. Important regulators in this signaling system are compounds in the insect saliva, which are often modified plant molecules.

Deciduous leaf drop reduces insect herbivory

Oecologia, 2007
Deciduous leaf fall is thought to be an adaptation that allows plants living in seasonal environments to reduce water loss and damage during unfavorable periods while increasing photosynthetic rates during favorable periods. Observations of natural variation in leaf shedding suggest that deciduous leaf fall may also allow plants to reduce herbivory.

Induced defense mechanisms in an aquatic angiosperm to insect herbivory

Oecologia, 2014
In 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.
