1.  To assess the degree of herbivore host-specificity in the moist tropical forest on Barro Colourado Island, Panama, I conducted an extensive series of feeding trials on the common insect herbivores from 10 tree species. 2.  The herbivores were offered leaves from both congeneric and confamilial plant species to their known host species, as well as leaves from the most abundant tree species in the forest. 3.  The amount of damage caused by these herbivores to young, expanding leaves was… 

Low host specificity of herbivorous insects in a tropical forest

It is shown that most herbivorous species feed on several closely related plant species, suggesting that species-rich genera are dominant in tropical floras, and monophagous herbivores are probably rare in tropical forests.

Host specialization of leaf-chewing insects in a New Guinea rainforest

The number of new herbivore species resulting from the addition of the xth plant species to the compound community can be described as y = cxk, where c and k are constants, which is an order of magnitude lower than previously suggested.

This conclusion, together with the recent downward revisions of extremely high estimates of tropical species richness, suggest that tropical ecosystems may not be as biodiverse as previously thought.

Host specialization and species richness of fruit flies (Diptera: Tephritidae) in a New Guinea rain forest

Frugivorous dacine fruit flies were studied in a lowland tropical rain forest in Papua New Guinea to determine their host specificity, abundance, and the number of species attacking various plant

No tree an island: the plant-caterpillar food web of a secondary rain forest in New Guinea

A plant–caterpillar food web from secondary vegetation in a New Guinean rain forest that included 63 plant species, 546 Lepidoptera species and 1679 trophic links between them was characterized.

Comparison of Herbivores and Herbivory in the Canopy and Understory for Two Tropical Tree Species 1

The Janzen–Connell model of tropical forest tree diversity predicts that seedlings and young trees growing close to conspecific adults should experience higher levels of damage and mortality from

Variation in Herbivore Damage to Invasive and Native Woody Plant Species in Open Forest Vegetation on Mahé, Seychelles

In the Seychelles invasive woody plants profit from herbivore release relative to the native species and that the amount of herbivory, and therefore its effect on species invasiveness or habitat invasibility, may be dependent on local community structure and composition.

No Indication of High Host-Plant Specificity in Afrotropical Geometrid Moths

The study contributes to the evidence that host-plant specificity of herbivores is not necessarily substantially higher in tropical than temperate regions, by comparing host-specificity patterns of closely related temperate (hemiboreal) species.

Four ways towards tropical herbivore megadiversity.

This work presents a comprehensive scheme in which tropical herbivore megadiversity can be partitioned into the following components: more host plant species per se, more arthropod species per plant species, higher host specificity of herbivores, or higher species turnover in the tropics than in the temperate zone.

Species richness of phytophagous beetles in the tropical tree Brosimum utile (Moraceae): the effects of sampling strategy and the problem of tourists

Phytophagous beetles on six mature living trees and two dead trees of Brosimum utile (Moraceae) were surveyed during 1 year in a tropical wet forest in Panama, confirming a prominent vertical stratification among this guild.



Host specificity of arboreal and free‐living insect herbivores in rain forests

It is suggested that the strength of association between communities of insect herbivores and their rainforest host-trees may depend on the following factors, acting at both the tree and rainforest community level: chemical traits of foliage, young foliage availability and enemy-free space.


Folivorous mammals do less damage than insects or pathogens but have evolved to cope with the high levels of plant defenses and, along with insect herbivores, may contribute to the maintenance of tree diversity.


It is concluded that current estimates of Arthropod species numbers are grossly underestimated; that there could be as many as 30 million species extant globally, not 1.5 million a, usually estimated.


Interspecific patterns of defense mechanisms are discussed in terms of current theories of plant apparency, and an alternative model for the evolution of plant defenses is presented.

Effects of leaf age and plant life history patterns on herbivory

Grazing rates (% leaf area eaten per day) on mature leaves of fast growing, shade-intolerant species (pioneers) were an order of magnitude greater than those on slow growing, Shade-tolerance species (persistents), and young leaves in both groups of species suffered significantly greater grazing damage than mature leaves.

Anti-Herbivore Defenses of Young Tropical Leaves: Physiological Constraints and Ecological Trade-offs

Many leaf developmental traits may be the result of selection by herbivores and pathogens, and most of the understanding of the costs and benefits of defenses and of the interplay between defenses and herbivore is based on research on mature leaves.

Ecological Characterization of a Costa Rican Dry Forest Caterpillar Fauna

The dry forests of Costa Rica's Santa Rosa National Park range from deciduous and 2 m tall to nearly evergreen and 30 m tall, and this vegetation and a complex mosaic of secondary succession in old fields and pastures supports at least 3 140 species of caterpillars.

A lesser predilection for bugs : Hemiptera (Insecta) diversity in tropical rain forests

The Hemiptera fauna of a moderately large and topographically diverse area of tropical rain forest in Sulawesi Utara, Indonesia is presented and the global estimates of 1.84–2.57 million species of insect are much lower than the 10–80 million predicted by Erwin and Stork from a study of tropical Coleoptera.

Insect diversity: facts, fiction and speculation*

Assessment of the faunal importance of the canopy in relation to that of other rain forest biotopes requires comparative quantitative studies, and the preliminary results of one such study suggest that over 42 million arthropods may be found in a hectare of Seram rain forest.

Temporal and spatial variability in insect grazing of the canopies of five Australian rainforest tree species.

Variability in herbivory is discussed in terms of plant-insect phenologies, plant defences, successional status of tree species, and insect behaviour.
