A new species of Ibitermes (Isoptera, Termitidae) from the Atlantic forest, northeastern Brazil
Provedor de dados: 76
Autores: Vasconcellos,Alexandre.
The sterile castes of Ibitermes inflatus sp. nov. from Rio Tinto, State of Paraíba, Brazil are described and illustrated. This is the first record of a species of Ibitermes from the Brazilian northeast and from the Atlantic Forest biome. The absence of ridges in the molar plate of the left mandible and the presence of granules of sand and silt mixed with organic matter in advanced stage of decomposition in the digestive tube of workers suggest that the species is a typical humus feeding termite.

Riqueza de cupins (Insecta, Isoptera) em áreas de Mata Atlântica primária e secundária do sudeste da Bahia
Provedor de dados: 76
Autores: Reis,Yana T.
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...

Padrão de distribuição de cupins na região urbana de Goiânia
Provedor de dados: 76
Autores: Costa,Diogo A; Espírito Santo Filho,Kleber do; Brandão,Divino.
Foi realizado um levantamento das espécies de cupins em Goiânia, GO, que constituem praga e sua distribuição foi relacionada com alguns fatores ambientais. Realizou-se uma amostragem em 600 edificações de várias idades localizadas em 20 bairros, e analisaramse os principais tipos de vegetação original. Foram registradas quatro espécies de cupins. As análises mostraram que a associação entre a frequência de infestação e o tipo de vegetação original apresentou baixa significância; e entre as idades dos bairros e das edificações apresentou alta significância e constatou-se que árvores próximas não podem ser consideradas uma causa importante do padrão de distribuição dos cupins.

Cupins de duas florestas de restinga do nordeste brasileiro
Provedor de dados: 76
Autores: Vasconcellos,Alexandre; Mélo,Ana Cerilza S.; Segundo,Eusébio de M. Vasconcelos; Bandeira,Adelmar G.
A estrutura da comunidade de cupins foi avaliada em duas florestas de restinga localizadas nos municípios de Mataraca e Cabedelo, Estado da Paraíba. Um protocolo padronizado de amostragem foi aplicado em cada área. Vinte e cinco espécies foram encontradas, sendo 19 em Mataraca e 15 em Cabedelo, com 9 espécies comuns às duas localidades. As espécies de Nasutitermitinae e as do grupo dos comedores de madeira foram dominantes em ambas as áreas. A baixa riqueza de espécies, em comparação com outros ecossistemas do Nordeste, e a baixa freqüência de encontros de humívoros e da subfamília Apicotermitinae podem estar relacionadas com as propriedades do solo das restingas. As espécies construtoras de ninhos conspícuos (todos arborícolas) foram Armitermes holmgreni...

Soil termites in primary forest, secondary forest and an agroforestry plantation system in central Amazonia.
Provedor de dados: 14
Autores: MARTIUS, C.; GOMES, E.; GARCIA, M. V. B.
Litter and soil termites were collected with soil cores (21cm diameter) in a primary forest site, a secondary forest site and two sites of a polyculture plantation system in central Amazonia (Brazil), in three-monthly intervals from 1997 to 1999. Termite genus diversity, abundance and biomass all were highest in the primary forest. The values in the secondary forest were half those of the primary forest, and they were lowest in the plantation systems, indicating that the latter sites may suffer from functional constraints concerning the process of organic residue decomposition.

Termites as Bioindicators of Habitat Quality in the Caatinga, Brazil: Is There Agreement Between Structural Habitat Variables and the Sampled Assemblages?
Provedor de dados: 82
Autores: Alves,W de F; Mota,AS; Lima,RAA de; Bellezoni,R; Vasconcellos,A.
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...

Termites in sugar cane in Northeast Brazil: ecological aspects and pest status
Provedor de dados: 82
Autores: Miranda,Carmélia S.; Vasconcellos,Alexandre; Bandeira,Adelmar G.
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 &amp;amp; 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...

Provedor de dados: 90
Autores: Lima,Sandra Santana de; Pereira,Marcos Gervasio; Pereira,Renato Nunes; Pontes,Rafael Moura de; Rossi,Celeste Queiroz.
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...

Termite assemblages in five semideciduous Atlantic Forest fragments in the northern coastland limit of the biome
Provedor de dados: 92
Autores: Souza,Heitor Bruno de Araújo; Alves,Wagner de França; Vasconcellos,Alexandre.
Termites are abundant organisms in tropical ecosystems and strongly influence the litter decomposition and soil formation. Despite their importance, few studies about their assemblage structures have been made in Brazilian Atlantic Forest fragments, especially in the area located north of the São Francisco River. This study aims to analyze the assemblage composition of five Atlantic Forest fragments located in the northern biome limit along the Brazilian coast. A standardized sampling protocol of termites was applied in each fragment. Thirty-three termite species belonging to twenty genera and three families were found in the forest fragments. The wood-feeder group was dominant both concerning to species richness and number of encounters in all areas. In...

External development of the entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae in the subterranean termite Heterotermes tenuis
Provedor de dados: 63
Autores: Moino Jr.,Alcides; Alves,Sérgio Batista; Lopes,Rogério Biaggioni; Neves,Pedro Manuel Oliveira Janeiro; Pereira,Roberto Manoel; Vieira,Solange Aparecida.
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...

Autores: Camargo-Dietrich,Célia R.R. de; Costa-Leonardo,Ana Maria.
Groups of Heterotemies tenuis (Hagen, 1858) from five infestation points were paired in bioassays to investigate the intercolony aggression. The combinations of arena sizes (Petri dishes of 6.0 and 9.0 cm) and temperatures (25 and 28 ºC) were assessed for effects on intraspecific agonism. Agonistic behavior was scored positive in arena if more than half of the starting number of termites was dead and injured after 17 hours. After the intraspecific encounters it was possible to delimitate three colonies from the five infestation points. No significant differential survival was seen in two different arena sizes and two different temperatures. These assays indicate that the factors governing the agonistic behavior in H. tenuis are complex and seems to be...

The histological study of the exocrine glands in the swarming females showed the presence of tergal glands, mandibular glands, salivary glands and sternal glands. Tergal and sternal glands are not developed in the physogastric queens, probably, because of a regression process. The development of mandibular glands is similar in swarming females and physogastric queens.

Termiteros del Plioceno y Pleistoceno de la provincia de Buenos Aires, República Argentina: Significación paleoambiental y paleozoogeográfica
Provedor de dados: 41
Autores: Laza,José H.
Se describen nuevas trazas fósiles atribuidas a Termitidae (Barberichnus bonaerensis igen. et isp. nov.). Las partes preservadas corresponden a cámaras y túneles de dos nidos de termitas, hallados en sendos paleosuelos, uno en la parte inferior de la Formación Buenos Aires (Pleistoceno medio) en el municipio de La Plata; el otro en niveles de la Formación San Andrés (Plioceno superior) localizada en la base de las barrancas marinas del municipio de Necochea. Las localidades de los nidos fósiles de termitas no coinciden con la actual distribución de la mayoría de las especies actuales de Termitidae, sugiriendo un cambio climático en la región hacia condiciones ambientales más secas y frías, cambio que se da progresivamente con vaivenes, desde el Plioceno...

Abstract: In detritus-based trophic systems, springtails, dung beetles, saprophagous calyptrate flies and termites consume and fragment organic matter and control populations of decomposer microorganisms, exerting a strong influence on energy and nutrient fluxes. A faunal inventory of these four groups of hexapods was performed in Serra de Santa Catarina (SSC), an area of arboreal-shrub caatinga located in the state of Paraíba, with the purpose of characterizing the assemblages of these taxa, and highlighting their unique links to the local ecosystem. Samplings were performed in May, 2014, and April, 2015, both during the rainy season. Standard sampling protocols for biodiversity inventory of the various taxa were used, including both active and passive...

High termite richness in an urban fragment of Atlantic Forest in northeastern Brazil
Provedor de dados: 49
Autores: Ernesto,Matilde Vasconcelos; Ramos,Elaine Folly; Moura,Flávia Maria da Silva; Vasconcellos,Alexandre.
Termites are very abundant in tropical ecosystems and have active roles in nutrient cycling and soil formation, but few studies of their assemblages have been undertaken in the Brazilian Atlantic Forest. The present study analyzed the composition of termite assemblages in a fragment of Atlantic Forest embedded within an urban matrix in northeastern Brazil. Five standardized sampling protocols of termites were applied, with a total sampling effort of 1500m2. We encountered 45 species of termites belonging to 25 genera and three families. The soil-feeders group demonstrated the greatest species richness, while wood-feeders species were the most abundant. The species richness of termite in the study area was the greatest yet recorded for an Atlantic forest...

Commercial gouache as a dye for termites in laboratory assays
Provedor de dados: 52
Autores: Brunow,Guilherme S.; Souza,Og de; Miramontes,Octavio.
Studies were performed to evaluate the suitability of a commercial gouache as an external marker for termite workers in lab assays. Dyed and non-dyed termites presented similar survival for the first 300 minutes since the experiment has began, and differed after this time. Mortality did not differ for termites dyed in two different colours from the same brand of gouache. It was concluded that commercial gouache could be a suitable marker for Cornitermes cumulans (Isoptera: Termitidae) termites, provided following restrictions were applied (i) tested hypotheses did not rely on times to death greater than 300 min., or (ii) experiments included "sham-dyed" termites (i. e., a "control" group with "dyed" individuals, rather than the tradicional control group...

Reproductive mechanisms in a Nasutitermes species (Isoptera: Termitidae)
Provedor de dados: 57
Autores: BUSCHINI,M. L. T.; LEONARDO,A. M. C.
The number of reproductive individuals present in colonies of Nasutitermes sp. was analysed, and its possible reproductive strategy discussed. Twenty-four nests were collected and opened, and a single queen and king were found in 17 of them. In the other 7 nests, no queen or king were neither found, nor any other reproductive individual. All quee ns were weighed, and the number of eggs laid by them was counted. No relationship between the volume of the nests and the weight of their respective queens was found, but the number of eggs laid by the queens during an hour was positively correlated to their weight .

Ação dos térmitas no solo
Provedor de dados: 65
Autores: Ferreira,Eric Victor de Oliveira; Martins,Vanessa; Inda Junior,Alberto Vasconcellos; Giasson,Elvio; Nascimento,Paulo César do.
A ordem Isoptera é bastante conhecida pelo seu potencial como praga, apesar dos cupins-praga constituírem a minoria dentro do grupo. Os cupins (térmitas) são invertebrados dominantes em ambientes terrestres tropicais e estão espalhados desde as florestas úmidas até as savanas, sendo encontrados até mesmo em regiões áridas, nos mais variados habitats. Esses insetos têm um papel destacado e ainda pouco estudado nos ecossistemas tropicais. Ciclagem de nutrientes, aeração, infiltração de água do solo, bioturbação, formação de agregados e decomposição de material orgânico, são processos influenciados pela ação dos térmitas, que vão, direta ou indiretamente, influenciar a formação dos solos e da paisagem onde se encontram. Sugerimos que uma maior abordagem deva...
