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. 

Comparing the plant–herbivore network topology of different insect guilds in Neotropical savannas

The hypothesis that the structure of plant–herbivore networks differs between guilds of galling, sucking, and chewing insects is tested.

Low host specificity and broad geographic ranges in a community of parasitic non-pollinating fig wasps (Sycoryctinae; Chalcidoidea).

It is proposed that long lived non-pollinators may disperse more gradually and be less reliant on infrequent long-distance dispersal by wind currents, and provide one more example of lack of strict codiversification in the geographic diversification of plant associated insect-communities.

Low host specificity and abundance of frugivorous lepidoptera in the lowland rain forests of Papua New Guinea

The very low incidence of seed damage suggests that pre-dispersal seed predation by Lepidoptera does not play a major role in regulating plant populations via density-dependent mortality processes outlined by the Janzen-Connell hypothesis.

Plants and gall hosts of the Tirimbina Biological Reserve, Sarapiqui, Costa Rica: Combining field sampling with herbarium records

The results demonstrate the utility of providing complete plant inventories when conducting gall inventories, and of using herbarium specimens and previous galls studies to infer gall diversity in a specific area.

Ecology and Diversity haracterization of entomogen galls from Mato Grosso do Sul , Brazil aria

The geographic distribution of gall morphotypes associated to the cecidomyiids Youngomyia pouteriae Maia, 2004, and Trotteria quadridentata MaIA, 2004 are expanded to the localities sampled in Mato Grosso do Sul.

A meta-analysis of the effects of galling insects on host plant secondary metabolites

It is found that galling insects are associated with significantly higher levels of tannins and phenolics; however, no difference was found for volatiles.

Polyphagy on unpredictable resources does not exclude host specialization: insects feeding on mushrooms.

This study highlights the multidimensional nature of ecological specialization: a high number of acceptable hosts does not preclude considerable discrimination among members of the available resource pool and is highlighted by individual-based analyses capable of capturing differences in partner-to-partner interaction intensities.

Diversity of insect galls associated with Eucalyptus alba & E. urophylla in altitudinal zones in Timor Island, Indonesia

Puspasari LT, Buchori D, Ubaidillah R, Triwidodo H, Hidayat P. 2021. Diversity of insect galls associated with Eucalyptus alba & E. urophylla in altitudinal zones in Timor Island, Indonesia.

Variation in community structure of gall‐inducing insects associated with a tropical plant supports the hypothesis of competition in stressful habitats

The low availability of resources for oviposition and the high density of gallers in xeric environments reinforce interspecific competition as an important structuring force for gall communities in these environments.



Species Richness of Galling Arthropods in Manaus, Amazon and the Surroundings of the Iguassu Falls

The data in Iguassuand Amazon, as well as the previous data in Indonesia and Japan, revealed that the galling species richness was considerably high in humidenvironments.

Richness of gall-inducing insects in the tropical dry forest (caatinga) of Pernambuco

The main gall inducing taxon was the Cecidomyiidae (Diptera), and the most common gall morphological types were spheroid and discoid, glabrous, predominantly green and with one chamber.

Diversity of gall-inducing insects in the high altitude wetland forests in Pernambuco, Northeastern Brazil.

The results of this study contribute to existing knowledge richness of galling insects and host-plant diversity in the altitudinal wetland forests of Northeastern Brazil.

Convergence in the variation of local and regional galling species richness

It is indicated that local factors may be the most important factors structuring the galling insect community on B. concinna and the richness of all galling species and galling cecidomyiids were strongly influenced by habitat.

Are gall midge species (Diptera, Cecidomyiidae) host-plant specialists?

It is concluded that gall morphotypes associated with information on the host plant species and attacked organs are reliable surrogates of the gall-inducing species.

Species Richness of Galling Arthropods in Brisbane, Green Island, and Daintree National Park in Northeastern Australia

The present data indicates that the species richness of galling arthropods is relatively high both under humid conditions and under high plant species richness in tropical rainforests.

Insect galls from savanna and rocky fields of the Jequitinhonha valley, Minas Gerais, Brazil

Most insect galls (82.6%) were caused by the Cecidomyiidae (Diptera) and leaves were the most frequently galled plant organs (51.7%).

Gall inducing arthropods from a seasonally dry tropical forest in Serra do Cipó, Brazil

The first study of gall-inducing arthropods and their host plant species ever undertaken in a Brazilian SDTF ecosystem indicates the need for an increased effort to catalogue the corresponding flora and fauna and further understand the implications of such rich diversity in these stressed and vulnerable ecosystems.

Diversity of galling arthropods and host plants in a subtropical forest of Porto Alegre, southern Brazil.

Seasonal sampling of galling arthropods and host plants in a humid subtropical forest of southern Brazil suggests that both plant richness and specific composition of the vegetation have a strong influence on galler richness at least for local scales, and suggests that sampling team experience is an important factor.

Diversity of gall-inducing insects in a Mexican tropical dry forest: the importance of plant species richness, life-forms, host plant age and plant density

A significant positive correlation between G II species richness and plant species richness in both deciduous and riparian habitats is found, suggesting that radiation of GII species may be associated with plant species species richness.
