Does spatial variation in insect herbivory match variations in plant quality? A meta-analysis.
Ecology LettersVariation in herbivore pressure has often been predicted from patterns in plant traits considered as antiherbivore defences. Here, we tested whether spatial variation in field insect herbivory is associated with the variation in plant quality by ...

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

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 ...

Insect adaptations to herbivory
1982Before feeding or oviposition any herbivorous insect is faced with the problem of locating its host plant both in space and time. It must be able to select its particular food plant(s) from amongst the complex array of available species and it must ensure that its period of feeding activity coincides with periods of plant availability.

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.

Insect herbivory in ecosystems
1982Whole ecosystem studies are complex and time consuming and it is not feasible to study every organism. Ecologists have usually concentrated on the apparently dominant groups of insect herbivores feeding on the dominant plant species. Often whole insect groups, particularly the sapsucking fauna, have been ignored.

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 ...

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.

The effect of rhizosphere microbes outweighs host plant genetics in reducing insect herbivory
Molecular Ecology, 2019Rhizosphere microbes affect plant performance, including plant resistance against insect herbivores; yet, a direct comparison of the relative influence of rhizosphere microbes versus plant genetics on herbivory levels and on metabolites related to ...
