A Mata Atlântica é considerada um dos biomas com maior diversidade do mundo, abrigando um grande número de espécies endêmicas, porém é um dos mais degradados do Brasil, restando menos de 8% de sua vegetação original. No Sudeste da Bahia, a floresta vem sofrendo um processo de deterioração, originado pelo desmatamento indiscriminado e o mau uso do solo. Nessa região, pouco se conhece sobre a fauna de cupins, onde não existia qualquer levantamento prévio. Os objetivos foram: 1) fazer uma primeira amostragem da fauna de Isoptera dessa parte da Mata Atlântica, através de duas técnicas de coleta; 2) comparar a riqueza de espécies de uma área de mata primária com outra de mata secundária; 3) comparar os resultados dos diferentes protocolos; 4) fazer... |

The composition of termite assemblages was analyzed in three caatinga sites of the Estação Ecológica do Seridó, located in the municipality of Serra Negra do Norte, in the state of Rio Grande do Norte, Brazil. These sites have been subjected to selective logging, and cleared for pasture and farming. A standardized sampling protocol for termite assemblages (30h/person/site) was conducted between September 2007 and February 2009. At each site we measured environmental variables, such as soil pH and organic matter, necromass stock, vegetation height, stem diameter at ankle height (DAH) and the largest and the smallest crown width. Ten species of termites, belonging to eight genera and three families, were found at the three experimental sites. Four feeding... |

The spatial distribution, abundance, and feeding habits of termites in a sugar cane plantation in Northeast Brazil were studied, and based on these ecological parameters, the pest status of the species was evaluated. Four species were found: Amitermes nordestinus Mélo & Fontes, Cylindrotermes nordenskioeldi Holmgren, Nasutitermes coxipoensis (Holmgren) and Syntermes nanus Constantino, which we reported by the first time in association to sugar cane. The abundance and spatial distribution (vertical and horizontal) of the termites were influenced mainly by the plant root biomass and soil organic matter. C. nordenskioeldi is harmful to sugar cane, A. nordestinus is a potential pest, while N. coxipoensis and S. nanus are not potential pests. The... |

O trabalho é um estudo taxonômico de Cylindrotermes Holmgren (Isoptera, Termitidae, Termitinae), incluindo a redescrição do gênero, a descrição de três espécies novas C. caata, C. capixaba e C. sapiranga, além da redescrição de quatro, das cinco espécies anteriormente conhecidas: C. parvignathus, C. brevipilosus, C. macrognathus e C. flangiatus. Os alados de C. brevipilosus e C. macrognathus são descritos pela primeira vez. Há ilustrações de todos os soldados e alados das espécies estudadas, bem como uma chave dicotômica de identificação baseada nos soldados. |

ABSTRACT This paper consists on a bibliometric analysis of the international influences of the book "Studies on termites from the Mato Grosso State, Brazil", by AGA Mathews (1977). The number of citations has increased over the years after the first citation. Mathews book was cited in articles, reviews, theses, dissertations, books, book chapters, abstracts in conference proceedings, comments and scientific notes. Most these studies are empirical and descriptive. The studies were conducted in 35 countries of the Neotropical, Palearctic, Afrotropical, Nearctic, Australasia and Indomalaya regions. 55% of the studies were carried out in Brazil. The journals Sociobiology and Insectes Sociaux, have social insect studies within its scope, and the highest number... |

Resumo: O objetivo deste trabalho foi avaliar a densidade e a diversidade da fauna epigeica e edáfica de invertebrados em cultivos de mandioca consorciada com adubos verdes. O estudo foi realizado em cultivos de mandioca (M) em consórcios com feijão-de-porco (FP), milheto (MI) e guandu-anão (G), em comparação ao cultivo de mandioca tradicional (ST), sem a presença de adubos verdes. Os invertebrados epigeicos foram coletados com armadilhas de queda (pitfall) e os edáficos foram coletados de monólitos de solo. Entre os invertebrados epigeicos, os grupos Collembola, Diptera e Formicidae predominaram em todos os consórcios, tendo sido mais de 80% da frequência relativa total (FR), enquanto entre os edáficos predominou o grupo Isoptera em todos os consórcios,... |

ABSTRACT Termites have peculiar activities in the soil, inducing significant changes in the soil properties. The objective of this study was to assess physical and chemical properties and soil organic matter to evaluate the effect of termite activity and termite mounds on the soil. Two toposequences were selected and divided in slope thirds (shoulder, backslope, and footslope). In each of these, four termite mounds were selected. Samples were taken from the soils and termite mounds (top, center, and base) along with a variety of termites for identification. Analyses were carried out for physical, soil texture, and chemical properties, as well as for particle size and chemical fractioning of organic matter. The species Cornitermes cumulans was found in all... |

Epigeous termite mounds are frequently observed in pasture areas, but the processes regulating their population dynamics are poorly known. This study evaluated epigeous termite mounds in cultivated grasslands used as pastures, assessing their spatial distribution by means of geostatistics and evaluating their vitality. The study was conducted in the Cerrado biome in the municipality of Rio Brilhante, Mato Grosso do Sul, Brazil. In two pasture areas (Pasture 1 and Pasture 2), epigeous mounds (nests) were georeferenced and analyzed for height, circumference and vitality (inhabited or not). The area occupied by the mounds was calculated and termite specimens were collected for taxonomic identification. The spatial distribution pattern of the mounds was... |

The subterranean termite Heterotermes tenuis is one of the main pests of sugarcane and eucalyptus in Brazil, and the use of entomopathogenic fungi, alone or associated to chemicals, is an efficient and environmentally favorable method for its control. Studies related to the fungal development on these insects are important due to the effect of insect behavior on entomopathogens. The objective of this work was to describe the external development of Beauveria bassiana and Metarhizium anisopliae on H. tenuis using Scanning Electron Microscopy (SEM), determining the duration of the different phases of fungal infection. Two fixation techniques for preparing SEM samples were also evaluated. Worker specimens of H. tenuis were inoculated with a 1 x 10(9) conidia... |
