Comunidades de insetos galhadores (Insecta) em diferentes fisionomias do cerrado em Minas Gerais, Brasil

Abstract

ABSTRACT. Galling insect (Insecta) communities in different "cerrado" physiognomies in Minas Gerais, Brazil. Studies on the communities ofgalli ng insects and their host plants were performed in three "cerrado" physiognomies that occ ur in Minas Gerais: "campo suj o", "ce'Tado" sensu slriclu, and "ce'Tadão". Galls and host plants were collected along transects in a total of3,OOO herbs, 300 shrubs and 135 trees in each physiognomy. Ninety two species 01' galling insects (morphotypes) on 62 host plant species of 28 families were found. The highest galling insect richness was observed in the "cen·ado". Approximate ly 75 .0% of galling insects belonged to the Cecidomy iidae (Diptera). The highest gall frequency was found on leaves (58.70%) ofthe host plants, and was glabrous (83.70%). Most gall shape were ellipti c (30.43%). A low similarity in galling insec t species was observed among the three sampled phys iognomies -the highest similarity index was observed between "cerrado" and "cam po sujo" (S~rense n index = 0.20), indicating that the presence of rare spec ies of ga lling insects might be common in these environments.

Effects of Environmental Heterogeneity on the Composition of Insect Trophic Guilds

“…Notably, xeric, hygrothermally-challenged environments were preferred for their nutritional value with typical sclerophyllous vegetation, confirming the results of Fernandes and Price (1991), Fernandes et al (1995) and Gonçalves-Alvim and Fernandes (2001).…”

Representativity of the genus Asphondylia Loew, 1850 (Diptera, Cecidomyiidae) in Brazil

“…Literature data were compiled from six papers retrieved from the Web of Science (Carneiro et al, 2009a;Maia, 2013a;Maia et al, 2008b;Maia & Fernandes, 2005;Gagné et al, 2001), 51 Brazilian gall inventories (Almada & Fernandes, 2011;Araújo et al, 2011;Araújo et al, 2014;Bregonci et al, 2010;Carneiro et al, 2009b;Coelho et al, 2009;Coelho et al, 2013a;Coelho et al, 2013b;Costa et al, 2014;Dreger-Jauffret & Shorthouse, 1992;Fernandes & Negreiros, 2006;Fernandes et al, 1988;Fernandes et al, 1997;Fernandes et al, 2001;Gagné et al, 2001;Gagné, 1994;Gagné, 2004;Gonçalves-Alvim & Fernandes, 2001;Julião et al, 2002;Maia & Carvalho, 2016;Maia & Fernandes, 2004;Maia & Fernandes, 2005;Maia & Oliveira, 2010;Maia & Souza, 2013;Maia et al, 1992;Maia et al, 2008a;Maia et al, 2014;Maia, 2001;Maia, 2004;Maia, 2011;Maia, 2013b;Maia, 2014;Mendonça et al, 2014;Oliveira & Maia, 2005;<...>…”

Patterns of gall infestation in Heteropterys byrsonimifolia A. Juss. in a forest-savannah ecotone

“…Gallers have different distributions, which depend on the habitat and vegetation type (Gonçalves-Alvim & Fernandes, 2001;Mendonça et al, 2010;Araújo & Guilherme, 2012). Investigating the effects of landscape on the density of galling insects is an important way to clarify these patterns in changing ecosystems.…”
