Abstract: We documented one of the most species-rich assemblages of tropical rain-forest Auchenorrhyncha, comprising 402 phloem- and xylem-feeding species, by sampling adults from forest vegetation. Further, we reared 106 species from larvae sampled on 14 plant species. Both xylem- and phloem-feeding guilds exhibited wide host-plant ranges, as 74% of species fed on more than one plant family. In comparison, using data extracted from the temperate-zone literature, phloem-feeders exhibited lower… Expand
Mesophyll cell‐sucking herbivores (Cicadellidae: Typhlocybinae) on rainforest trees in Papua New Guinea: local and regional diversity of a taxonomically unexplored guild
Host specificity of a guild of sucking insects tapping leaf mesophyll cells was surveyed for the first time in the tropics, on 65 woody species from a lowland rainforest in Papua New Guinea, to estimate that there may be at least 2775 typhlocybine species in PNG, in comparison to the global total of only 4508 taxonomically described species.

The global distribution of diet breadth in insect herbivores
A global dataset is used to investigate host range for over 7,500 insect herbivore species covering a wide taxonomic breadth and interacting with more than 2,000 species of plants in 165 families to ask whether relatively specialized and generalized herbivores represent a dichotomy rather than a continuum from few to many host families and species attacked and whether diet breadth changes with increasing plant species richness toward the tropics.

Diversity of Planthoppers (Hemiptera: Delphacidae) on Maize Crops and Edge Grasses in Mexico.
A high diversity of delphacids was found in the edge grasses during the dry season and rainy season, and the most abundant species was M. propinqua representing 67.5% of the specimens collected. Expand
Gall‐forming insects in a lowland tropical rainforest: low species diversity in an extremely specialised guild
1. Gall‐forming insects are a guild of endophages that exhibit a high level of fidelity to their host plants, however, their level of host specificity is seldom explicitly tested.
An entomocentric view of the Janzen–Connell hypothesis
In 1987, in the first issue of Conservation Biology, Edward O. Wilson wrote about the “little things that run the world” – the importance and conservation of insects (Wilson, 1987). Readers of InsectExpand


Guild-specific patterns of species richness and host specialization in plant-herbivore food webs from a tropical forest.
A complex, species-rich plant-herbivore food web for lowland rain forest in Papua New Guinea is described, resolving 6818 feeding links between 224 plant species and 1490 herbivore species drawn from 11 distinct feeding guilds. Expand
Habitat and successional status of plants in relation to the communities of their leaf‐chewing herbivores in Papua New Guinea
These results contradict several previous studies of successional trends in temperate regions and suggest that many tropical successions start with pioneer trees, rather than with annual herbs, and may present a permanent and predictable habitat for insects even at the earliest stages, with no advantage for polyphagous species.

Insects on Plants: Explaining the Paradox of Low Diversity within Specialist Herbivore Guilds
It is shown that herbivore assemblages are enriched with generalists because these are more completely sampled from regional species pools, and the relative species diversity among guilds is thus scale dependent, as the importance of specialized guilds increases with plant diversity. Expand
Host specificity of Lepidoptera in tropical and temperate forests
It is suggested that greater specialization in tropical faunas is the result of differences in trophic interactions; for example, there are more distinct plant secondary chemical profiles from one tree species to the next in tropical forests than in temperate forests as well as more diverse and chronic pressures from natural enemy communities.

Relation between temporal persistence of host plants and wing length in leafhoppers (Hemiptera: Auchenorrhyncha)
Because of this inability of leafhopper populations to decrease significantly the quality of their resources, a high population density cannot be used as a predictor of future quality of these resources, which is information essential for efficient dispersal behaviour. Expand
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. Expand
Seasonality of sap-sucking insects (Auchenorrhyncha, Hemiptera) feeding on Ficus (Moraceae) in a lowland rain forest in New Guinea
Sap-sucking insects (Auchenorrhyncha, Hemiptera) were sampled quantitatively from the foliage of 15 species of Ficus in a lowland rain forest in Papua New Guinea to reveal a significant correlation between seasonality and host specificity, so that polyphagous species had, on average, larger populations than specialists.

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. Expand
Host specificity of insect herbivores in tropical forests
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. Expand

There were major differences in faunal composition between sites and diversity appeared to peak at elevations between 600–1000 m, and seasonal changes were also significant but generally lower than between methods or sites. Expand
