“…Due to lack of information on the biology and natural history of the immature stages of lepidopterans and their host plants in the Cerrado, a research program was initiated in the 1990s (Diniz and Morais 1997;Morais et al 1999;Morais and Diniz 2004;BendichoLopez et al 2006;Pessoa-Queiroz et al 2008). However, after almost 20 years of research, information on the majority of the species is still limited due mainly to the large number of species found in the Cerrado or to the complexity of interactions between the lepidopteran and host plants.…”

How do frequent fires in the Cerrado alter the lepidopteran community?

Despite the great biodiversity of lepidopterans, there are few studies focusing on caterpillars and the effects of fire on their community structure in the Cerrado. The aim of this study was to evaluate the effects of frequent fires every 2 years for 16 years, on the Lepidoptera larval community hosted on Byrsonima coccolobifolia (Malpighiaceae). The study was carried out in the Cerrado sensu stricto in the Reserva Ecológica of the Instituto Brasileiro de Geografia e Estatística (IBGE-RECOR) (15°55 0 -15°58 0 S, 47°52 0 -47°55 0 W), in Distrito Federal, Brazil, from December 2005 to August 2006. We selected two burned parcels, one of which was burned during the mid-dry season (FM) and the other of which burned in the late dry season (FL), in addition to a preserved, unburned parcel (FA). In each parcel, 900 plants of B. coccolobifolia were inspected for caterpillars, which were then collected and reared in a laboratory of the University of Brasilia. We found 480 caterpillars from 49 species distributed in 16 Lepidoptera families. The frequency of plants with larvae, the number of caterpillars and species composition varied among parcels. In the unburned parcel the frequency of plants with caterpillars was 2.4 and 5.2 times higher than in burned parcels (FM and FL), respectively. The species richness did not differ among parcels, and an asymptotic curve was nearly reached in only the unburned parcel. The dominant species in the preserved parcel was Cerconota achatina (Elachistidae). In the FM, the dominant species was Concana mundissima (Noctuidae) and in the FL, the dominant species was Stenoma salome (Elachistidae). The dissimilarity between unburned and burned parcels was 64%. Results indicated that fire events have a strong negative impact on caterpillar abundance and species composition.

“…Unfortunately, the phenology of the northern Chilean Andes butterflies has been little investigated. However, as also mentioned for some other Neotropical lepidopterans (Bendicho-Lopez et al 2003;Pessoa-Queiroz et al 2008;Muniz et al 2012), an important role of the host plant phenology was mentioned for the temporal variation of the host-specialist butterfly Teriocolias zelia andina Forbes, 1928 (Pieridae, Coliadinae) in the same study site (Vargas 2012;Vargas & Benítez 2013). Thus the pattern here reported for N. faga, with a striking variation in the abundance between two successive summers, deserves further attention as the collections were performed at different flowering stages.…”

Rapid response to abiotic and biotic factors controls population growth of two invasive drosophilids (Diptera) in the Brazilian Savanna

An intrinsic property of invaders that determines many of the effects they produce in the areas they colonize is their great abundance. However, a lack of data generally hampers the exploration of the complex interactions of factors that regulate the abundance of most invasive populations. This lack of data generally hinders the understanding of the invasion process and, more specifically, interferes with the management of these populations. This paper uses hierarchical complex models to investigate how temperature, humidity, competitive interactions and resource availability affect the growth rates of naturalized populations of two invaders in the Brazilian Savanna: the African Drosophila simulans and Zaprionus indianus. We also assess how morphological (life-history) and demographic traits mediate these effects. Our results suggest that the population growth rates of both species depend on complex interactions between several of the studied variables but are regulated primarily by rapid and direct responses to resource availability. We found evidence that resources determine immediate oviposition rates, inducing a very rapid regulation of population sizes (in one generation, i.e., approximately 1 month). Our study also demonstrates a lower predictability for Z. indianus and we suggest that this finding is a result of the shorter evolutionary history of Z. indianus in the Brazilian Savanna. These results, valid for the system we have investigated, if validated by other studies, will help to increase the mechanistic understanding of invasions and may contribute to the development of effective management strategies to mitigate their effects on natural and agro-ecosystems.
