Insect herbivory in Gondwana plants
Journal of Palaeosciences, 2016Plant–insect interaction is dominant in the extant flora and it is estimated that more than one million species of insects directly or indirectly survive on plants. In comparison, such association is limited in extinct flora, mainly due to problem in identifying structural features associated with the insect wronged plant fossils. Concerted efforts and

Insect herbivory on mangrove leaves in North Queensland*
Australian Journal of Ecology, 1987AbstractEstimates of leaf damage by insect herbivores are presented for 25 species of mangrove plants, comprising canopy and understorey species. Leaf area loss was highly variable among the species sampled, with means ranging from 0.3 to 35.0% of expanded leaf area.

Effects of tree diversity on insect herbivory
Journal of Forestry Research, 2021Tree diversity has long been considered a key driver of insect herbivory in forest ecosystems. However, studies have given contradictory results: increased tree diversity can have positive, negative or neutral effects on insect herbivory. Since many issues can complicate the tree-herbivore interactions, the descriptor ‘tree diversity’ per se actually ...

Wound and insect herbivory responsive genes in poplar
Biotechnology Letters, 2006Insect herbivory leads to induced resistance to subsequent infestations in plants. This is due in part to feeding-induced expression of genes that can lead to reduced palatability and/or digestibility of the plant material. We identified 57 distinct differentially expressed genes from poplars that were either infested by gypsy moth (Lymantria dispar ...

Significance of phototoxic phytochemicals in insect herbivory
Journal of Chemical Ecology, 1986The significance of the wide range of phototoxins, occurring in many plant species, with respect to their role in insect herbivory and on insects, is not fully understood. The types of compounds include polyacetylenes, quinones, furanocoumarins, tryptophan- and tyrosine-derived alkaloids and are distributed throughout some of the major families of ...

Insect herbivory and woody plants
1982Wood 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, 2007AbstractBiodiversity 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
1982In 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, 2016AbstractArthropods 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, 1988Standing 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 ...
