The gall midges (Diptera, Cecidomyiidae) from three restingas of Rio de Janeiro State, Brazil

“…A different result was found in restingas, where Eulophidae and Eurytomidae were the predominant families. FERNANDES et al (1988) found similar results in their research in Minas Gerais, Brazil. These data suggest that Eulophidae and Eurytomidae may be the most important natural enemies of gall midges in the Neotropical region.…”

Gall-inducing insects of an Araucaria Forest in southern Brazil

“…This trend is uncommon for insect galls, which are usually reported to occur predominantly on leaves (DregerJauffret & Shorthouse 1992; Fernandes et al 1988;Maia & Fernandes 2004;Moreira et al 2007;Maia et al 2008). Only a few studies report more galls on stems (African savanna; Veldtman & McGeoch 2003) or stems and buds (rupestrian fields; Carneiro et al 2009b).…”

“…Considering gall occurrence, isolated galls were more frequent, as reported by other studies. Fernandes et al (1988) hypothesized that galls which occur isolated would be favored because parasitoid pressure would be diminished due to the greater searching time implied by isolation.…”

“…However, due to the concentration of taxonomists and research groups, most surveys were conducted at sites in southeastern Brazil, including areas under cerrado (e.g., Fernandes et al 1988;Gonçalves-Alvim & Fernandes 2001;UrsoGuimaraes & Scarelli-Santos 2006), Atlantic forest (e.g., Fernandes et al 2001;Moreira et al 2007) and specific ecosystems within these biomes (e.g., rupestrian fields, Maia & Fernandes 2004;Carneiro et al 2009b, andrestinga, Oliveira &Maia 2005;Maia et al 2008).…”

Galls in rhizome of an aquatic macrophyte, Eichhornia azurea (Swartz) kunth (Pontederiaceae), in Jataí Ecological Station, Luiz Antônio, SP, Brazil

“…There are several reports of galls in plants of most environments throughout the world (Felt, 1994;Mani, 1964;Gagné, 1989Gagné, , 1994Fernandes et al, 1988Fernandes et al, , 1997b. On the other hand, few authors have reported gall in aquatic macrophytes (Gagné, 1989;Fernandes & Lara, 1997a).…”
