“…Second, the amount of plant resources increases for a few months after a fire, with almost all herbaceous plants producing flowers or regrowing vigorously, allowing epigaeic arthropod species to take advantage of the nutrients released by fire (COUTINHO 1990, MIRANDA et al 2002. These available resources should attract many herbivore species, such as Orthoptera and Hemiptera, which benefit from the regrowth of plants (CHAMBERS & SAMWAYS 1998, MARINI-FILHO 2000, ANDERSEN et al 2003. In turn, an increase in the abundance of these species should attract their predators (CHEN & WISE 1999).…”

“…Despite the great diversity and functional importance of savanna arthropods, they have received little attention by researchers working in the cerrado (see OLIVEIRA & MARQUIS 2004) and other tropical savannas (ANDERSEN et al 2003). Of the few studies conducted in the cerrado so far, most have dealt with one or a few taxonomic groups and have reached different conclusions about fire effects (e.g., MORAIS & BENSON 1988, PRADA et al 1995, SEYFFARTH et al 1996, VIEIRA et al 1996, MARINI-FILHO 2000, MARTINS et al 2004, MORAIS et al 2007, KNOECHELMANN & MORAIS 2008. Therefore, understanding the general responses of arthropods to different fire regimes remains a challenge.…”

ABSTRACT. Fire is a major determinant of structure and dynamics in savannas, and the rapid increase of human activities in this biome has changed the natural burning regime. The effects of fire on the fauna of the cerrado (Brazilian savanna) are still poorly understood, and studies comparing sites frequently and infrequently burned are scarce. In this study, the abundance of epigaeic arthropod orders and trophic guilds was assessed in cerrado sites located in the Brazilian Central Plateau that were subjected to three burning frequencies: frequent (HighFi), intermediary (MidFi), and infrequent (LowFi).In general, we found a positive relationship between the abundance of epigaeic arthropods and fire frequency. When arthropods were analyzed by orders, the abundance of Collembola and Orthoptera was lower in the LowFi site, while for Hemiptera, it was higher in the MidFi site. No significant differences were found for Hymenoptera, Coleoptera, and Araneae.The abundance of detritivores and herbivores decreased from HighFi to LowFi, but did not change significantly for omnivores and predators. These results indicate that some arthropod groups may not only be resilient to fire effects, but actually might benefit from fire effects in the cerrado. Characterizing arthropod responses to burning frequency at high taxonomic or functional levels is important for applied studies. Based on the results of the current study, springtails and ants seem to be particularly appropriate focal groups for further exploratory studies on the effects of fire at the species level.

“…This increase may result from intense regrowth, which may produce new oviposition sites and new environments for these species. At the same time, nearby areas were available to act as a source for re-colonization [17]. However, the rarefaction curves did not reach an asymptote.…”

“…The effects of fire on the structure, composition and diversity of plants in the cerrado are far more extensively documented [8][9][10][11][12] than the effects on the fauna [13][14][15]. The knowledge of the effects of fire on insect herbivores and their natural enemies is even more limited [3,16,17].…”

Among the mechanisms that influence herbivorous insects, fires, a very frequent historical phenomenon in the cerrado, appear to be an important modifying influence on lepidopteran communities. The purpose of this study was to compare the richness, abundance, frequency, and composition of species of caterpillars in two adjacent areas of cerrado sensu stricto, one recently burned and one unburned since 1994, on the experimental farm "FazendaÁgua Limpa" (FAL) (15 • 55 S and 47 • 55 W), DF, Brazil. Caterpillars were surveyed on two plant species, genus Erythroxylum: E. deciduum A. St.-Hil. and E. tortuosum Mart. (Erythroxylaceae). We inspected a total of 4,196 plants in both areas, and 972 caterpillars were found on 13.3% of these plants. The number of plants with caterpillars (frequency) differed significantly between the areas. The results indicate that recent and accidental fires have a positive effect on the abundance of caterpillars up to one year postfire, increase the frequency of caterpillars associated with Erythroxylum species in the cerrado and do not affect the richness of caterpillars on these plants. Moreover, the fires change the species composition of caterpillars by promoting an increase in rare or opportunistic species.

“…Para essas espécies especializadas num recurso tão efêmero, sincronizar suas fenologias com a da planta hospedeira é muito importante na sobrevivência e manutenção das populações (Breedlove & Ehrlich 1972, Thompson 1983, Jordano et al 1990. Por outro lado, quatro tipos de minadores foram registrados em R. montana em área de cerrado acidentalmente queimado na FAL e, nesse caso, suas abundâncias foram maiores (Smith 1995, Marini-Filho 2000.…”

-Richness of lepidopteran species in the cerrado is high. The confirmation of this richness is based on adult records but knowledge of larvae-host plants interactions is still incipient. The main purpose of this work was to identify folivorous caterpillar species on Roupala montana Aubl. in areas of a Brazilian cerrado sensu stricto, their dietary range, and the relative age of the consumed leaves richness. Three data sets, collected from 1991 to 2004 were used in this study. All caterpillars found on the host plants in the field were collected and reared in the laboratory. Sixtytwo lepidopteran species from 22 families were recorded; they were found feeding on new (8%) and mature (92%) leaves of R. montana. Cerconota sciaphilina (Zeller) (Elachistidae), two unidentified Gracillariidae species and, one species of Gelechiidae fed only on new leaves. These species showed a short life cycle, which was very syncronized with the host plant foliar phenology. Among the species feeding on mature leaves, 36 were considered polyphagous and, these showed a large variation in the use of the food resource. Twenty-six species were found only on R. montana, 58% were very rare, a character that difficults the analysis of their dietary range. The monophagous species on R. montana were: Chlamydastis platyspora (Meyrick) (Elachistidae), Stenoma cathosiota Meyrick (Elachistidae), Idalus prop. sublineata (Rothschild) (Arctiidae), and Eomichla sp. (Oecophoridae). KEY WORDS: Chlamydastis platyspora, dietary range, Eomichla, Idalus, Stenoma cathosiotaRESUMO -No cerrado a riqueza de espécies de lepidópteros é alta e confirmada por registros de adultos, mas o conhecimento sobre as interações das lagartas com suas plantas hospedeiras ainda é incipiente. Os objetivos deste trabalho foram conhecer a riqueza de espécies de lepidópteros folívoros em Roupala montana Abl., a idade relativa das folhas consumidas pelas espécies e suas amplitudes de dietas. Os dados foram coletados em áreas de cerrado sensu stricto de Brasília de 1991 a 2004. As lagartas encontradas foram coletadas e criadas no laboratório. Foram registradas 62 espécies de lepidópteros de 22 famílias, consumindo folhas jovens (8%) e maduras (92%) de R. montana. Cerconota sciaphilina (Zeller) (Elachistidae), duas espécies de Gracillariidae e uma de Gelechiidae consumiram somente folhas jovens e, apresentaram ciclo de vida curto e sincronizado com a fenologia foliar da planta hospedeira. Das espécies que consomem folhas maduras, 36 foram consideradas polífagas e mostraram variação muito grande na utilização do recurso. Vinte e seis espécies foram encontradas somente em R. montana, sendo que 58% delas são bastante raras, o que dificulta análise de amplitude de dieta. As espécies monófagas em R. montana foram Chlamydastis platyspora (Meyrick) (Elachistidae), Stenoma cathosiota Meyrick (Elachistidae), Idalus prop. sublineata (Rothschild) (Arctiidae) e Eomichla sp. (Oecophoridae).
