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.

“…Caterpillar's abundance variation, among years, is relatively common in cerrado areas (Andrade et al 1995; Diniz et al 2000a, b;Bendicho-López et al 2003). This temporal variation (seasonal and annual) in caterpillar abundance makes it diffi cult to distinguish the possible effects of fi re on this fauna.…”

“…This means that they eat leaves with low nitrogen and high fi ber contents (Marquis et al 2001), which can be another factor that partially explain the rarity of caterpillars. In the case of S. cathosiota, whose larvae fed on mature leaves (Bendicho-López et al 2006), the peaks of caterpillar frequencies occurred in the dry season (June-July), but there was a relative high frequency of caterpillars in the beginning of the rainy season (OctoberNovember).Caterpillar's abundance variation, among years, is relatively common in cerrado areas (Andrade et al 1995; Diniz et al 2000a, b;Bendicho-López et al 2003).

Variação Temporal e Espacial na Abundância das Lagartas de Stenoma cathosiota Meyrick (Lepidoptera: Elachistidae) no Cerrado de Brasilia, DF RESUMO -As lagartas da mariposa Stenoma cathosiota Meyrick alimentam-se de folhas de Roupala montana Aubl. (Proteaceae) em áreas de cerrado do Distrito Federal. Elas constroem abrigos juntando folhas da planta onde se alimentam e empupam. São parasitadas por uma vespa (Hymenoptera: Braconidae) que emerge da pupa. A abundância de lagartas de S. cathosiota e a freqüência do parasitismo foram comparadas em duas áreas de estudo: uma com queimadas freqüentes (bienal) e a outra com queimadas esporádicas (1987 e 1994). Na área com baixa freqüência de queimada, a variação na abundância das lagartas entre anos foi signifi cativamente diferente (χ² = 24,06; gl. = 1; P = 0,000). No entanto, a variação na abundância de lagartas entre áreas, para o mesmo período de tempo, não diferiu estatisticamente (χ² = 3,45; gl. = 1; P = 0,063). A freqüência do parasitismo foi alta, ocorrendo em 29% das lagartas coletadas e não diferiu entre as áreas. A grande variação temporal na abundância de lagartas no cerrado difi culta a determinação dos efeitos do fogo sobre essa fauna.PALAVRAS-CHAVE: Braconidae, Stenomatinae, fogo, parasitismo, planta hospedeira ABSTRACT -The caterpillars of Stenoma cathosiota Meyrick feed on Roupala montana Aubl.(Proteaceae) in the cerrado of the Distrito Federal, Brazil. They construct shelters by joining leaves of the plant where they feed and pupate. The caterpillars are parasitized by a wasp (Hymenoptera: Brachonidae), which emerges from the pupae. Caterpillar abundance and parasitism frequency were associated in an area of frequently burned cerrado (biennial fi re) and in another area that burns sporadically (1987 and 1994). For S. cathosiota, the variation among years in a single area, with sporadic fi res, was greater than the variation among areas with different fi re regimes. Caterpillar abundance among years was signifi cantly different in the area that burns sporadically (χ² = 24.06; df. = 1; P = 0.000). However, there were no signifi cant differences on caterpillar abundance between areas for the same period (χ² = 3.45; df. = 1; P = 0.063). Parasitism frequency was high, reaching 29% of the collected caterpillars, and did not differ among areas. The great temporal variation in abundance of lepidopteran caterpillars in the cerrado makes it diffi cult to determine the effects that fi re exerts over this fauna.KEY WORDS: Braconidae, Stenomatinae, fi re, host plant, parasitismKnowledge of the effects of fi re over cerrado vegetation has grown quickly in recent years (Hoffman 1998;Miranda et al. 2002Miranda et al. , 2004. However, its effects on the fauna are still poorly understood. In accidentally burned, protected areas, there has been a tendency for greater herbivory and greater abundance of some herbivorous insects during the fi rst regrowth after the fi re (Prada et al. 1995, pers. obs.). For example, the frequency of a gall insect was greater and they had hig...

“…O grupo é especialmente rico nas Américas, com cerca de 1.200 espécies, distribuídas desde os Estados Unidos até a Argentina (AIELLO 1981). As lagartas de três espécies dessa subfamília são bem conhecidas na região do cerrado, incluindo as suas plantas hospedeiras e ciclos de vida: Gonioterma exquisita Duckworth, 1964, Gonioterma indecora (Keafott, 1911) (TRAVASSOS-FILHO 1972 e Cerconota achatina (Zeller, 1855) (ANDRADE et al 1995).…”

História natural da mariposa Chlamydastis smodicopa (Meyrick) (Lepidoptera, Elachistidae, Stenomatinae)

O gênero Chlamydastis Meyrick, 1916 (Elachistidae, Stenomatinae) possui 82 espécies descritas da região Neotropical. Chlamydastis smodicopa (Meyrick, 1915) tem local tipo o Estado de Amazonas, Brasil. No cerrado de Brasília, Distrito Federal, as lagartas de C. smodicopa são folívoras externas restritas à planta hospedeira Styrax ferrugineus Nees & Mart. (Styracaceae). De junho de 2000 a junho de 2001, foram vistoriados 243 indivíduos de S. ferrugineus, e encontradas 38 espécies de lagartas de Lepidoptera em 26% das plantas examinadas. C. smodicopa foi a espécie mais comum em S. ferrugineus mas, apesar disso, ocorreu somente em 7% das plantas. As lagartas apresentam no último ínstar cabeça castanho escuro, placa protorácica marron com faixa amarela na sua margem anterior, tegumento cinza com faixas dorsais e subdorsais marron e amarela, e atingem 30 mm de comprimento. Lagartas são solitárias e constróem abrigos ovóides com duas folhas unidas com fios de seda e com as duas extremidades abertas: uma utilizada para alimentação e a outra para deposição de fezes. Um novo abrigo é construído, à medida que as lagartas crescem ou quando as folhas tornam-se senescentes. No último instar a lagarta constrói um casulo no interior do abrigo foliar, onde ocorre o desenvolvimento da pupa que, em condições de laboratório, teve uma média de 18 dias. As lagartas tiveram a maior freqüência de agosto a setembro, no final da estação seca no cerrado.
