“…Os estudos de insetos cecidógenos têm sido feitos em diferentes espécies vegetais, principalmente, relacionados com Cecidomyiidae (Diptera), abrangendo aspectos como descrição de novas espécies (Maia 1996;Maia 1996a); associações com parasitóides (Maia & Monteiro 1999;Maia & Tavares 2000); descrição de estágios de desenvolvimento (Maia 1993) e padrões que infl uenciam na diversidade de galhas (Fernandes & Price 1988;Fernandes et al 1996;Fernandes et al 1997b). Entretanto, outros trabalhos têm visado a descrição e caracterização de galhas associadas a diferentes famílias vegetais Fernandes et al 1997a;Maia 2001;Maia & Fernandes 2004;Urso-Guimarães et al 2003;Urso-Guimarães & ScareliSantos 2006).…”

Recebido em 12/06/2008. Aceito em 5/11/2009 RESUMO -(Ocorrência e caracterização de galhas entomógenas em uma área de fl oresta estacional semidecídua em Goiânia, Goiás, Brasil). Em uma área de fl oresta estacional semidecídua do Campus Samambaia da Universidade Federal de Goiás, Goiânia, Goiás foram coletados 34 tipos de galhas entomógenas, durante o período de [2005][2006][2007]. As galhas ocorreram em 20 espécies de plantas de 12 famílias, sendo Leguminosae (9), Styracaceae (6) e Ulmaceae (4) as que apresentaram o maior número de morfotipos de galhas. Galhas foliares e caulinares foram as mais comuns. Em relação à morfologia foram coletadas galhas globóides, discóides, elipsóides, cilíndricas e coniformes. A coloração variou entre o verde, amarela, marrom e vermelha. As galhas estavam agrupadas ou isoladas e eram glabras ou pilosas. Os Cecidomyiidae (Diptera) foram os principais cecidógenos e os parasitóides encontrados pertenciam às famílias Eulophidae, Torymidae, Pteromalidae, Encyrtidae (Hymenoptera). Este é o primeiro relato de galhas em quatro espécies de plantas hospedeiras para a região Neotropical.

In an area of seasonal semideciduous forest situated on Campus Samambaia of the Universidade Federal de Goiás in Goiânia, Goiás 34 types of insect galls were collected during the period [2005][2006][2007]. The galls occurred in 20 species of plants from 12 families, with Leguminosae (9), Styracaceae (6) and Ulmaceae (4) having the greatest number of gall morphotypes. Leaf and stem galls were the most widespread. Concerning gall morphology, the following were collected: globoid, discoidal, ellipsoidal, cylindrical and conical. The colour varied from green to yellow, brown and red. The galls were isolated or grouped and glabrous or pilose. The principal inducers were Cecidomyiidae (Diptera) and the parasitoids found were of the families Eulophidae, Torymidae, Pteromalidae, Encyrtidae (Hymenoptera). This is the fi rst report of galls in four species of host plants for the Neotropical region.

“…Nevertheless, these host plant groups could be rich in gall-maker species exactly because they conform to the pattern suggested by the hypothesis, that is, flushing synchronously, resprouting and being speciose (and with these species in sympatry). It is a frequent question in gall-maker biology that a few genera or families of plants seem to bear so many species of gall-makers, for example Baccharis (Fernandes et al 1996), Quercus, Eucalyptus (Blanche and Westoby 1995) and Myrtaceae in general (Maia 1993, Gagné 1994, Maia et al 1996, particularly Eugenia. If it were possible to show whether these groups have synchronisation in flushing and resprouting in response to fire (along with hosting more gall-maker species) more commonly than comparable control ones, it would be a good indication that high gall-maker species richness is actually resulting from the presence of these physiological traits.…”

Galling insect diversity patterns: the resource synchronisation hypothesis

A new hypothesis is proposed to explain the insect gall‐maker species richness pattern found by Price et al. (1998; J. Biogeogr. 25: 581–591). First, it is necessary to consider an explicit model for speciation in this group of insects, and host‐shifts seem to be the most likely way by which gall‐makers can speciate. Since most galls are induced on young plant tissue, and mainly on leaves, the dynamics of leaf flushing in different vegetation types (how many plant species flush synchronously) can be of capital importance determining possible host‐shifts for dispersing insect females. I suggest that vegetation types with synchronous leaf flushing are more likely to harbour higher insect gall‐maker species richness, and this is why the pattern found by Price et al. (1998) showed low species richness of these insects for tropical rain forests and high richness for Mediterranean‐like vegetation. Additionally, Mediterranean‐like vegetation suffers seasonal influence of fires, and plants resprouting in response to this can provide further synchronous leaf flushes during which more host‐shifts can occur. Plant diversity is also of capital importance underlying the host‐shifting process in different biomes. Finally, I suggest a few possible ways of testing the hypothesis.

“…These studies cover aspects such as the description of new species (Maia, 1996a;Maia, 1996b); associations with parasitoids (Maia & Monteiro, 1999;Maia & Tavares, 2000); description of developmental stages (Maia, 1993) and patterns that influence the diversity of galls (Fernandes & Price, 1988;Fernandes et al, 1996;Fernandes et al, 1997a). However, other studies have focused on the description and characterization of galls from different localities Fernandes et al, 1997b;Maia, 2001;Maia & Fernandes, 2004;Urso-Guimarães et al, 2003;Urso-Guimarães & Scareli-Santos, 2006).…”

Abstract. Insect galls of the Floresta da Cicuta (Volta Redonda, RJ, Brazil). Galls are changes in the pattern of growth and development of plant tissues or organs in response to the action of an inducing organism, usually an insect. The goal of the present study was to inventory the insect galls of the Floresta da Cicuta (Volta Redonda, RJ, Brazil). The collections were carried out along all the trails, totaling 16 hours of sampling. Forty-three morphotypes of insect galls were found in 24 plant species (18 genera and 15 families). Sapindaceae and Euphorbiaceae were the most richness host plant families. Six new records of host plant species are presented: Senefeldera verticillata (Vell.) Croizat. (Euphorbiaceae), Inga acuminata (Fabaceae), Ocotea elegans (Lauraceae), Ouratea stipulata (Ochnaceae), Psychotria nuda (Rubiaceae) and Cestrum intermedium (Solanaceae). Most of the galls occurred on leaves (n = 21) and stems (n = 18), followed by buds (n = 2), two gall morphotypes occurred simultaneously on leaves and stems. One-chambered galls were more frequent (n = 31), as well as glabrous galls (n = 33). The gallers belong to three insect orders: Diptera (Cecidomyiidae), Hemiptera, and Lepidoptera. The associated fauna comprised parasitoids (Hymenoptera), inquilines (Hemiptera and Coleoptera) and successors (Isoptera and Acari).
