25. Ecoepidemiology and biology of Eratyrus mucronatus Stål, 1859 (Hemiptera: Reduviidae: Triatominae), a sylvatic vector of Chagas disease in the Brazilian Amazon
Introduction Eratyrus mucronatus Stål, 1859 is a wild triatomine vector of Trypanosoma cruzi Chagas, 1909. However, little is known regarding the biology and ecoepidemiology of this triatomine in the Brazilian Amazon. The present study describes

26. Caste polymorphism of apterous line of the Neotropical termite Nasutitermes corniger (Motschulsky) (Isoptera, Termitidae)
Termite societies are structured by individuals that can be grouped into castes and instars. The development of these instars in most species occurs in irregular patterns and sometimes is distinguished subcastes in physical systems that originate polymorphic soldiers and workers. In this study, we characterized the morphological diversity of castes of aptero

27. Very low mitochondrial variability in a stingless bee endemic to cerrado
Partamona mulata is a stingless bee species endemic to cerrado, a severely threatened phytogeographical domain. Clearing for pasture without proper soil treatment in the cerrado facilitates the proliferation of termite ground nests, which are the nesting sites for P. mulata. The genetic consequences of these changes in the cerrado environment for bee populat

28. Composição e variabilidade enantiomérica de α-pineno em Constrictotermes cyphergaster (Silvestri, 1901) (Isoptera; Termitidae) / Composition and enantiomeric variability of α-pinene in Constrictotermes Cyphergaster (Silvestri, 1901) (Isoptera; Termitidae)
Termites are eusocial insects of isoptera order that part in seven families. In this study we analyze the chirality of α-pinene in the defensive secretion that C. cyphergaster (Isoptera, Termitidae, Nasutitermitinae) this compound showed that among the majority of termite volatile. Along with checking the chirality was made a study seeking to correlate

30. Environmental effects on the nest abundances and biomasses of three nest-building termite species (Insecta: Isoptera) in a non-flooded forest in Central Amazonia / Efeitos ambientais sobre as abundâncias e biomassas de três espécies de cupins construtores (Insecta: Isoptera) em uma floresta de terra firme na Amazônia Central
A teoria ecológica sugere que a resposta biológica à variação ambiental está frequentemente sujeita à interação entre fatores limitantes, mas as implicações metodológicas disto para o estudo da distribuição das espécies são controversas. Este trabalho usa padrões de variação espacial das abundâncias de uma espécie de palmeira (Arecaceae)

31. Diversidade molecular de procariotos em solo de cupinzeiro e seu agente Cornitermes cumulans
Symbiosis between insects and prokaryotes are recognized as essential to the survival of these invertebrates. The bacterial community in the gastrointestinal tract of termites, social insects, is diverse and the function of this microbiota has been characterized. This study investigated the molecular diversity of prokaryotes in soil of the mound and its agen

32. Laboratory and field evaluation of Metarhizium anisopliae var. anisopliae for controlling subterranean termites
The efficacy of the Metarhizium anisopliae strain ARSEF 6911 was determined in the laboratory and field against two sugarcane pests, Microtermes obesi Holmgren and Odontotermes obesus Rambur (Termitidae: Isoptera). The susceptibility of both termite species to different conidial suspensions (1 × 10(10), 1 × 10(8), 1 × 10(6) and 1 × 10(4) conidia/ml) was

33. Termites as Bioindicators of Habitat Quality in the Caatinga, Brazil: Is There Agreement Between Structural Habitat Variables and the Sampled Assemblages?
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 assemblage

35. Nature et propriétés de l'horizon diagnostic de Latosols du Plateau Central brésilien.
The Latosols correspond to about 40% of the Brazilian Central Plateau. They are characterized by low activity clay, little horizon differentiation, a weak macrostructure and a strong microgranular structure resulting in microaggregates 50 to 300um in size. Ten Latosols (L) were selected along a 350-km long regional toposequence across the South American Surf

36. Mecanismos de defesa em ninhos de cupins (Insecta: Isoptera) / Mechanisms of defense in termite nests (Insecta: Isoptera)
Cupins apresentam um elaborado sistema de defesa, porém seus ninhos são frequentemente invadidos por uma variedade de organismos. Os mecanismos que permitem a invasão em cupinzeiros ainda não foram elucidados. Sendo assim, o objetivo desta dissertacão foi compreender os mecanismos de defesa em ninhos de cupins. Para isso, levantamos a hipótese que falh
