Host specificity of a guild of sucking insects tapping leaf mesophyll cells (Auchenorrhyncha: Typhlocybinae) was surveyed for the first time in the tropics, on 65 woody species from a lowland rainforest in Papua New Guinea (PNG). Typhlocybinae species were host specific, feeding on 1–3 (median 1) plant species. Their assemblages did not functionally connect populations of different plant species, as an overwhelming majority (> 99%) of tree species pairs coexisting in the same forest did not…

Results of the study suggest that the leaf architecture-related herbivory trends under greenhouse conditions are similar to those occurring in natural ecosystems when considering the functional significance of particular leaf traits, and remain relevant at the scale of particular plant taxa with disregard of spatial factor.

Saltahojas (Typhlocybinae) y su relación con los síntomas de enfermedades en un campo de frijol (Phaseolus vulgaris L.)

The identified species of leafhoppers present in a production field of bean in Guines, Mayabeque, Cuba and the observation of their relationships with disease symptoms on the plants showed symptoms representative of hopperburn, phytoplasma and virus diseases, which were related to vectors.

Saproxylic moths reveal complex within-group and group-environment patterns

Investigation of saproxylic moths within the Białowieża Primeval Forest in Poland indicates mutually independent fungal colonization events by sa proxylic moth species, and thus a possible mechanism exists for competition avoidance with other saproxy Alic moths.

Mapping and understanding the diversity of insects in the tropics: past achievements and future directions

Recent progress in molecular taxonomy, proliferation of community phylogenies, improved food web census techniques and an increasing focus on experiments promise an exciting time for tropical entomology.

Distribución espacial y temporal de Empoasca spp. (Typhlocybinae) en un campo de frijol (Phaseolus vulgaris L.)

The objective of the present work was the determination of the spatial and temporal pattern distribution of Empoasca spp. and its relationship with weather variables of interest in a 26 ha black bean

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.

Quantifying diet breadth through ordination of host association.

An index of host range based on observed associations between plants and insects, and the calculation of multivariate distances among plants in ordination space is proposed, finding that host use is clustered in multivariate space with respect to associations observed across all of the butterfly taxa.

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.

Influential entomology: a short review of the scientific, societal, economic and educational services provided by entomology

The formation of national entomological societies in the early and mid‐19th century heralded the blossoming of entomology as a scientific discipline.



Low host specificity in species-rich assemblages of xylem- and phloem-feeding herbivores (Auchenorrhyncha) in a New Guinea lowland rain forest

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.

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.

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.

Species richness of insect herbivore communities on Ficus in Papua New Guinea

The high faunal overlap among Ficus communities and the importance of local resources for insect herbivores suggest that highly specialized interactions between insect Herbivores and Ficus in Papua New Guinea have not been conserved in evolutionary time.

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.

Unprecedented ichneumonid parasitoid wasp diversity in tropical forests

It is shown with primary data that the species richness of Ichneumonidae is markedly underestimated in tropical areas and that latitudinal diversity patterns in the family remain uncharacterized, and the true extent of tropical orthocentrine diversity is revealed.

Low beta diversity of herbivorous insects in tropical forests

Low beta diversity was documented in groups with differing host specificity (fruitflies and ambrosia beetles), suggesting that dispersal limitation does not have a substantial role in shaping the distribution of insect species in New Guinea lowland rainforests.

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.

Diversity and assemblage structure of phytophagous Hemiptera along a latitudinal gradient: predicting the potential impacts of climate change

Assessment of species richness and structure of phytophagous Hemiptera communities along a latitudinal gradient indicated that, at least in the short term, species richness patterns of these communities may be similar to that found today.

Local Species Richness of Leaf‐Chewing Insects Feeding on Woody Plants from One Hectare of a Lowland Rainforest

Most of the herbivore diversity was associated with plant diversity on the familial and generic levels, and Lepidoptera was the most speciose taxon in the local fauna, followed by Coleoptera and orthopteroids (OrthopterA and Phasmatodea).
