ABSTRACT: Pest insects are one of the major factors affecting the productivity of sugarcane, and especially those associated with the soil, which damage the crop if not controlled. There is little information on the insect associated with the soil in the sugarcane crop in the state of Mato Grosso do Sul, Brazil. This study evaluated the occurrence, abundance and population variation of soil-associated insects in sugarcane crops in four counties in the state of Mato Grosso do Sul during a period from September 2009 to August 2010. For the capture of insects, deep in the soil trenches were (50 x 50 x 30 width x length x depth). It was observed that county of Maracaju has a high incidence of soil insects in sugarcane crop. Specimens of the family Scarabaeidae are abundant in sugarcane fields of the state of Mato Grosso do Sul, being Liogenys suturalis the predominant species. Soil insects of the Chrysomelidae family were found with greater abundance in Dourados and Naviraí while Noctuidae, represented only by the Hyponeuma taltula, occurred mainly in Dourados. Insects of the family Termitidae occur in sugarcane fields in the counties of Maracaju and Naviraí but not in Nova Alvorada do Sul and Dourados. Sphenophorus levis and Metamasius hemipterus were alsoreported in the sugarcane fields from Maracaju, being the occurrence these species the first record in the Mato Grosso do Sul State. The determined occurrence of different soil insects in the sugarcane fields may help in their management in the four counties studied.

Abstract Objective To characterize the trophic composition of soil macrofauna in two animal husbandry systems in four municipalities located in the Dry Corridor of Nicaragua. Materials and Methods The study area comprised the municipalities Rivas, Belén, La Conquista and Diriamba, all located in the Dry Corridor of Nicaragua. In each municipality four farms were evaluated: two with conventional animal husbandry systems and two with silvopastoral systems. Rivas and Belén, where there was only one farm of each system, were excepted. The study lasted eight months and the sample collection of the edaphic macofauna was carried out every 60 days. The collected specimens were identified to the taxonomic category of families. The biological activity was determined through the grouping into the categories soil engineers, predators, herbivores and detritivores. Results The family composition was different between systems, with higher richness in the silvopastoral system, where six classes, 15 orders and 33 families were found. A total of 11 593 macrofauna individuals were recorded in the silvopastoral system, higher value than the conventional one, where 3 062 were found. The difference between systems was marked by the number of individuals found in the Formicidae and Termitidae families (4 150 and 2 126 individuals/m2, respectively), which represented 54 % of the total individuals present in the silvopastoral systems. Conclusions The highest family richness and quantity of individuals were obtained in the silvopastoral system, which proves its importance in animal husbandry exploitations.

Resumen Objetivo Caracterizar la composición trófica de la macrofauna del suelo en dos sistemas ganaderos en cuatro municipios localizados en el Corredor Seco de Nicaragua. Materiales y Métodos El área de estudio comprendió a los municipios de Rivas, Belén, La Conquista y Diriamba, todos ubicados en el Corredor Seco de Nicaragua. En cada municipio se evaluaron cuatro fincas: dos con sistemas ganaderos convencionales y dos con sistemas silvopastoriles. Se exceptuaron Rivas y Belén, donde solo hubo una finca de cada sistema. El estudio duró ocho meses y la recolección de muestras de la macrofauna edáfica se realizaron cada 60 días. Los especímenes recolectados se identificaron hasta la categoría taxonómica de familias. La actividad biológica se determinó mediante la agrupación en ingenieros del suelo, depredadores, herbívoros y detritívoros. Resultados La composición de familias fue diferente entre sistemas, con mayor riqueza en el silvopastoril, donde se encontraron seis clases, 15 órdenes y 33 familias. Se registraron 11 593 individuos de la macrofauna en el sistema silvopastoril, valor superior al convencional, donde se hallaron 3 062. La diferencia entre sistemas estuvo marcada por el número de individuos encontrados en las familias Formicidae y Termitidae (4 150 y 2 126 individuos/m2, respectivamente), las que representaron 54 % del total de individuos presentes en el sistema silvopastoril. Conclusiones La mayor riqueza de familias y cantidad de individuos se obtuvo en el sistema silvopastoril, lo cual evidencia la importancia de este en las explotaciones ganaderas.

Resumen La mayoría de las termitas plagas de área urbana en Brasil son especies exóticas, pero algunas especies nativas también están comenzando a representar un problema creciente. Este estudio tuvo como objetivo identificar las especies de termitas que infestan árboles y casas en la ciudad de Campos dos Goytacazes, en el norte del estado de Río de Janeiro. Los árboles de calles de dieciséis vecindarios fueron inspeccionados y los ataques por termitas fueron registrados. También se realizaron entrevistas con propietarios de residencias de los mismos vecindarios y sus domicilios fueron inspeccionados para verificar la ocurrencia de ataque de termitas. Las termitas fueron registradas en 17 % de los 1.307 árboles inspeccionados. La especie más frecuente fue Coptotermes gestroi (51 % de los árboles infestados), Nasutitermes corniger y Microcerotermes strunckii fueron especies de ocurrencia intermedia (38 % y 14 %, respectivamente) y Microcerotermes arboreus (1 %) fue la menos común. Las infestaciones de árboles por más de una especie ocurrieron en 14 % de los casos (n = 31). Las infestaciones de termitas también se presentaron en 26 % de las residencias inspeccionadas (n = 1.020). Las cuatro especies que causaron daños en domicilios fueron Cryptotermes brevis, C. gestroi, N. corniger y M. strunckii. La especie más común, encontrada en 133 residencias, fue C. brevis (51 %). C. gestroi y N. corniger pueden ser consideradas especies secundarias en términos de la presencia en las residencias pero fueron responsables por más daños estructurales que C. brevis que atacó principalmente el mobiliario.

Abstract Most pest termites in urban areas in Brazil are exotic species, but native species are becoming an increasing problem. This study aimed to identify termite species infesting trees and houses in urban areas of Campos dos Goytacazes, in the north of Rio de Janeiro State. Trees in the streets of sixteen neighborhoods were inspected for termites. Inspections and interviews were also conducted to verify the occurrence of termites in houses. Termites were recorded in 17 % of the 1,307 trees surveyed. Coptotermes gestroi was the most frequent species (51 % of infested trees), Nasutitermes corniger and Microcerotermes strunckii were present in 38 % and 14 % of infested trees, respectively, and Microcerotermes arboreus was the least common (1 %). Different termite species coexisted in 14 % of the infested trees (n = 31). Termite infestations were recorded in 26 % of the surveyed households (n = 1,020). Four species were identified as causing damage: Cryptotermes brevis, C. gestroi, N. corniger, and M. strunckii. The most common species was C. brevis, affecting 133 residences (51 %). C. gestroi and N. corniger were less frequent, but they were responsible for more structural damage than C. brevis, which mainly attacked furniture.

ABSTRACT The objective of this work was to evaluate the forest restoration of the basin of Guapiaçu river in Cachoeiras de Macacu, Rio de Janeiro state, using the families of Termites as tools for environmental assessment. We analyzed the population fluctuation and feeding guilds of the families of Termites: Kalotermitidae, Rhinotermitidae and Termitidae. Six sampling points were arranged along Guapiaçu river, five points being inferred in reforestation carried out in the basin and a point in a regeneration control area. Quantitative and qualitative surveys followed standard protocols and the samples were obtained directly, without baits. Thirty species within 25 genera were identified and the family Termitidae was the most frequent. The termite fauna of the control point P06 was the richest. From the frequencies of occurrence of the species related to their trophic guild, an ecological evaluation table of the environments was proposed. The P05 area, rich in plant species, presented the greatest similarity to the natural regeneration area P06. The majority of the species was classified as xilophagous.

The protection of biodiversity is critical to ecosystem function and is a primary management goal for conservation areas globally. Maintaining a current inventory of known diversity is a central component of achieving this goal and serves as an essential starting point for future research endeavours. Since the first published survey of termites in South Africa's Kruger National Park (KNP) over 55 years ago, our understanding of termite diversity has expanded sufficiently to merit an update and formal checklist. Here we revise the inventory of termite diversity in KNP and summarise the taxonomic and functional diversity of termites in the park. A thorough review of recent termite research in KNP added 6 new genera and 13 species to what was found in Coaton's original survey, with one genus, Anenteotermes, recorded for the first time in southern Africa. Based on the updated species checklist, the majority of genera in the park belong to Feeding Group II (39%) and the Termitidae family (75%). CONSERVATION IMPLICATIONS: In savannas, termites play crucial roles in nutrient cycling, water redistribution and plant dynamics. Systematically cataloguing termite diversity and assemblage composition in the park provides an essential baseline for scientific research, aids biodiversity conservation efforts and encourages scientists and managers to consider termites in ecosystem functioning and management. Having more detailed descriptions of genera, species and feeding groups allows for more tangible, ecologically relevant attributions of termite influence, facilitates enhanced inquiry and allows for more realistic quantification of termite roles in key ecosystem processes.

Resumen Se estimó la composición de termitas asociada a plantaciones de Pinus caribaea de diferentes edades, establecidas en terrenos previamente ocupados por sabana seminatural y pastos artificiales, en la meseta de San Pedro en la Orinoquía colombiana (Villanueva, Casanare). Utilizando el protocolo del transecto, se muestrearon cuatro edades de plantación y áreas con pastos artificiales y sabana seminatural en dos épocas climáticas: húmeda 2013 y 2014 (marzo - abril) y seca de 2013 (noviembre - diciembre). La termitofauna encontrada estuvo compuesta de 28 especies pertenecientes a las familias Termitidae (Apicotermitinae, Nasutitermitinae, Termitinae, Syntermitinae) y Rhinotermitidae. Las plantaciones de siete años con poda y sin entresaca fueron las más diversas y la sabana seminatural alcanzó un mayor número de especies con respecto a los pastos introducidos, sin variaciones importantes en época de muestreo. La especie humívora Anoplotermes sp. 1 y la xilófaga Heterotermes tenuis fueron las más frecuentes en todas las edades de plantación, mientras en los otros usos del suelo el grupo más frecuente fue el humívoro con predominancia de Anoplotermes spp. Gracias al mejoramiento del microclima y al aumento de la disponibilidad de recursos alimenticios en plantaciones de pino de edades avanzadas, la diversidad y abundancia de termitas en este monocultivo es significativamente mayor que en pastos o sabanas, lo que sugiere que las termitas están interactuando con la dinámica natural de las plantaciones al contribuir en la descomposición del material celulósico y el mejoramiento de la fertilidad de los suelos.

Abstract Termite abundance and diversity on Pinus caribaea stands established on lands previously occupied by a seminatural savanna and artificial grass were examined. Sampling was done during the transition from the dry to the rainy season in 2013 and 2014 (March - April) and the rainy to the dry season in 2013 (November - December) in plantations established in the Colombian Orinoco basin region, commonly known as “Mesa de San Pedro” (Villanueva, Casanare). Using the transect protocol, stands of Pinus caribaea of four different ages, and areas with introduced grass and seminatural savanna were sampled. Termite fauna was composed of twenty eight morphospecies belonging to the Termitidae (Apicotermitinae, Nasutitermitinae, Termitinae, Syntermitinae) and Rhinotermitidae (Heterotermitinae and Rhinotermitinae) families. Seven year-old pine stands without pruning or thinning had the most diversity, while natural savanna had a greater number of species than introduced grasses. No significant differences were observed between sampling seasons. The humivorous species Anoplotermes sp. 1 and the xylophagous Heterotermes tenuis were the most common in pine stands, while several species belonging to the humivorous genus Anoplotermes spp. predominated in pastures and savanna vegetation. Changes in the microclimate and increased availability of food resources in older pine stands may explain the higher diversity and abundance of termites in this monoculture as compared to pastures or savanna vegetation, suggesting that termites are interacting with the natural dynamics of plantations by contributing to the decomposition of cellulosic material and the improvement of soil fertility.

In order to determine the diversity and functionality of soil macrofauna as biological indicator of soil health and the effect of management practices in productive systems of Moringa oleifera Lam., a study was conducted in areas of the National Agricultural University, Nicaragua. The essays lasted nine months, in which agroecological management and conventional management practices were implemented. The soil macrofauna was sampled through the methodology developed by the International Tropical Soil Fertility and Biology Program. Taxonomic identification at phylum, class, order and family level was performed, as well as of functional groups: detritivores, soil engineers, herbivores and predators. The non-parametric Kruskal-Wallis test was applied to determine statistical differences in the variation of density per taxon and functional group per management system. The density of individuals was statistically different (p < 0,05) between management systems at class, order and family level. Diversity was higher in agroecological conversion, and a higher equitability of families stood out. The functional groups were different between systems, with dominance of soil engineers (64,22 %) in agroecological conversion, and of detritivores (74,19 %) in conventional management. Association was found of the management practices with the density and diversity of the soil macrofauna; and the organisms Formicidae, Termitidae and Coleoptera, which interacted with M. oleifera in different development stages, were identified. The number of taxonomic units constituted an indicator that allowed to distinguish between the management systems, soil health and transformation dynamics of the chemical, physical and biological properties of each system.

Con el objetivo de determinar la diversidad y funcionalidad de la macrofauna edáfica como indicador biológico de la salud del suelo y el efecto de prácticas de manejo en sistemas productivos de Moringa oleifera Lam., se llevó a cabo un estudio en predios de la Universidad Nacional Agraria, Nicaragua. Los ensayos tuvieron una duración de nueve meses, en los que se implementaron prácticas de manejo agroecológico y manejo convencional. La macrofauna edáfica fue muestreada mediante la metodología desarrollada por el Programa Internacional Biología y Fertilidad del Suelo Tropical. Se realizó identificación taxonómica a nivel de phylum, clase, orden y familia; así como de grupos funcionales: detritívoros, ingenieros del suelo, herbívoros y depredadores. La prueba no paramétrica Kruskal-Wallis se aplicó para determinar diferencias estadísticas en la variación de la densidad por taxón y grupo funcional por sistema de manejo. La densidad de individuos resultó estadísticamente diferente (p < 0,05) entre sistemas de manejo a nivel de clase, orden y familia. La diversidad fue mayor en conversión agroecológica, y se destacó una mayor equitatividad de familias. Los grupos funcionales fueron diferentes entre sistemas, con dominancia de los ingenieros del suelo (64,22 %) en conversión agroecológica, y de los detritívoros (74,19 %) en manejo convencional. Hubo una asociación entre las prácticas de manejo con la densidad y la diversidad de la macrofauna del suelo; y se identificaron los organismos Formicidae y Termitidae y del Coleoptera, que interactuaron con M. oleifera en diferentes estados de desarrollo. El número de unidades taxonómicas constituyó un indicador que permitió distinguir entre los sistemas de manejo, la salud del suelo y la dinámica de transformación de las propiedades químicas, físicas y biológicas de cada sistema.

En esta contribución se da a conocer el primer registro de termiteros fósiles para la región Mesopotámica de Argentina, y su disposición espacial, al tiempo que se discuten sus afinidades taxonómicas e implicancias paleoambientales. Las estructuras fósiles pertenecen a nidificaciones de insectos sociales atribuibles a miembros de la Familia Termitidae, y se ubican en la zona de contacto entre la base de la Fm. Toropí/Yupoí (Pleistoceno tardío) y el tope de la Fm. Ituzaingó (Mioceno tardío-Plioceno). Se las identifica en los alrededores del Arroyo Toropí (28°36' S y 59°02' W), Departamento Bella Vista, provincia de Corrientes. El estudio de las nidificaciones y su disposición espacial se realizó en cinco campos de termiteros mediante su relevamiento y descripción morfológica. La morfología de las estructuras estudiadas coincide claramente con la de los nidos de termitas, en donde resulta característica una fuerte muralla externa. La caracterización de campo, yacencia, desarrollo, frecuencia, tamaños e interrelaciones de los termiteros fósiles y actuales sugieren una estrecha similitud con montículos del género Cornitermes. La morfología presente muestra también cierta semejanza con Tacuruichnus farinai, descripta para el Piso/Edad Marplatense (Plioceno) de la región Pampeana. Por otro lado, el análisis fitolítico indicó que las cantidades y las morfologías fitolíticas son semejantes tanto en los termiteros actuales como en los fósiles. Desde un punto de vista paleoambiental, la abundancia de estos termiteros en el contacto entre las mencionadas unidades indicaría la existencia de suelos bien desarrollados, con abundante vegetación graminosa y condiciones húmedas y cálidas con estacionalidad marcada.

In this contribution we show the first termite nests fossil record presence from the Mesopotamian region of Argentina and its spatial distribution. At the same time taxonomic affinities and paleoenvironmental implications are discussed. The discovery takes place in the contact area between the base of the Toropí / Yupoí formations (late Pleistocene) and the top of the Ituzaingó Fm. (late Miocene-Pliocene), around the Toropí stream (28°36' S y 59°02' W), Bella Vista Department, Corrientes province. These fossil structures belong to nestings of social insects, such as the termite nests type. They could be attributable to representatives of the Termitidae Family. The study of nestings and their spatial arrangement was carried out on five termite nest fields, by surveying and detailed morphological description thereof. The morphology of the studied structures clearly matches with termite nests, with a typical strong outer wall. Characterization of field development, frequency, size and relationships of extant and fossil termite nests suggest a close similarity with mounds of the Cornitermes genus. Furthermore the morphology of these fossil termite nests also shows some resemblance to Tacuruichnus farinai, described for the Marplatanse Stage (Pliocene) of the Pampean region. From a paleoenvironmental point of view, the abundance of these termite nests in the contact between these units indicates the existence of well developed soils with abundant grassy vegetation and humid warm conditions with marked seasonality.

The chemical composition of the front gland of termites has been studied for over 40 years. The genus Nasutitermes, considered the most evolved of the Termitidae family, has a peculiarity that sets it apart from the others: a caste of soldiers that carry a terpenic mixture used in defense. This secretion is formed by mono, sesqui and diterpenes from trinervitane, kempane and rippertane skeletons, only found in termites. This article sought to review the scientific literature and contribute to the knowledge on the chemical composition of the secretion of the Nasutitermes soldiers from the interesting aspects of its behavior.

Con el objetivo de establecer la incidencia y distribución de termitas en cuatro tipos de cultivos de cítricos de la costa Caribe de Colombia, se muestrearon 64 huertos de cinco departamentos (Atlántico, Bolívar, Cesar, Córdoba y Magdalena). Se utilizó el método de búsqueda exhaustiva en nidos y galerías de termitas en el árbol del cítrico y sus alrededores. Se realizaron mapas de distribución y mediante análisis de varianza se comparó la incidencia de termitas entre especies de cítricos, categorías de edad del cultivo y entre zonas de muestreo (departamento y municipio). Para las mencionadas comparaciones no se encontraron diferencias estadísticamente significativas. En total, se revisaron 1975 árboles de los cuales 899 presentaron termitas; el 64% correspondió a los huertos de naranja, el 27,30% a limón pajarito y el 8,70% restante a los cultivos de limón tahití y pomelo. En las muestras se encontraron representadas dos familias: Termitidae (57%) con diez géneros (Anoplotermes, Amitermes, Cortaritermes, Microcerotermes, Nasutitermes, Neocapritermes, Orthognathotermes, Ruptitermes, Rhynchotermes y Termes) y Rhinotermitidae (43%) con dos géneros (Coptotermes y Heterotermes). Se identificaron 17 especies y se destacan por su abundancia y amplia distribución en el área de estudio Microcerotermes cf. arboreus (59%), Heterotermes convexinotatus (38,50%) y H. tenuis (27,50%). La presencia de M. cf. arboreus, H. convexinotatus, H. tenuis, Coptotermes testaceus, C. crassus y Amitermes foreli constituyen los hallazgos más importantes del trabajo, ya que se reportan como especies de importancia forestal en Colombia, por lo que se recomienda continuar más estudios en cultivos de cítricos.

In order to establish the incidence and distribution of four types of termites in citrus crops of the Caribbean coast of Colombia, were sampled 64 crops distributed in 61 farms in five departments (Atlántico, Bolívar, Cesar, Córdoba, and Magdalena). We used the exhaustive method of search termite nests and galleries in the citrus tree and its surroundings. Distribution maps were made with the occurrence of termites and with the ANOVA to compare the occurrence of termites among citrus species, age categories of the crop and between sampling areas (department and municipality). For the above comparisons statistically significant differences were not found. In total, 1975 trees were reviewed from which 899 had termites, 64% came from the crops of orange, 27.30% from common lemon tree and the remaining 8.70% from tahiti lemon crop and grapefruit. The samples were represented two families: Termitidae (57%) with ten genera (Anoplotermes, Amitermes, Cortaritermes, Microcerotermes, Nasutitermes, Neocapritermes, Orthognathotermes, Ruptitermes, Rhynchotermes and Termes) and Rhinotermitidae (43%) with two genera (Coptotermes and Heterotermes). 17 species were important for their abundance and wide distribution in the study area: Microcerotermes cf. arboreus (59%), Heterotermes convexinotatus (38.50%) and H. tenuis (27.50%). The presence of M. cf. arboreus, H. convexinotatus, H. tenuis, Coptotermes testaceus, C. crassus and Amitermes foreli are the most important findings of this work, because these termites are reported as important species for the Colombian forested, so it is recommended to do further research.

Se estimaron la diversidad y la abundancia relativa de termitas en asociación con plantaciones de caucho (Hevea brasiliensis) de diferentes edades en un núcleo forestal de la altillanura bien drenada de los Llanos Orientales (Puerto López, Meta). Se muestrearon tres edades de plantación en dos épocas climáticas: lluviosa de 2009 (mayo, julio) y seca de 2010 (febrero, marzo), utilizando el método de transecto con modificaciones. Se encontraron 10 especies pertenecientes a las familias Termitidae (Apicotermitinae, Termitinae, Nasutitermitinae, Syntermitinae) y Rhinotermitidae (Heterotermitinae). La diversidad de termitas en plantaciones de caucho mayores a dos años fue predominantemente xilófaga y humívora siendo Anoplotermes spp., Heterotermes convexinotatus y Grigiotermes sp. las especies con mayor frecuencia. La diversidad y abundancia de termitas xilófagas en asociación con el cultivo del caucho fue favorecida por la disponibilidad de recursos en las plantaciones de mayor desarrollo pero en ningún caso se observó actividad dañina sobre el cultivo. Los resultados sugieren un papel importante de H. convexinotatus en el reciclaje de residuos de madera, especialmente, en los rodales de mayor edad.

The diversity and relative abundance of termites in association with rubber-tree (Hevea brasiliensis) plantations was estimated for different aged stands in well-drained plateau in the Llanos Orientales (Puerto López, Meta). Three plantation ages were surveyed in two climate seasons: rainy in 2009 (May, June) and dry in 2010 (February, March), using the transect method with modifications. Ten species were found belonging to the families Termitidae (Apicotermitinae, Termitinae, Nasutitermitinae, Syntermitinae) and Rhinotermitidae (Heterotermitinae). Termite diversity in rubber plantations older than two years was predominately xylophagous and saprophagous, with Anoplotermes spp., Heterotermes convexinotatus and Grigiotermes sp. being the most common species. The diversity and abundance of xylophagous termites in association with rubber trees was favored by the availability of resources in the more well developed plantations, but in no case was any damaging activity observed in the crop. The results suggest an important role for H. convexinotatus in the recycling of wood residues, especially in the older tree plantations.

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 classificação das espécies em grupos tróficos. As áreas de estudo foram a "Mata da Esperança" (mata primária) e a "Reserva Zoobotânica da CEPLAC" (secundária), localizadas no município de Ilhéus, BA. Foram feitas coletas chamadas aqui de "qualitativas" e "quantitativas", que seguiram protocolos determinados, e as amostras foram obtidas por coletas diretas, sem uso de iscas. Foram identificadas 38 espécies, distribuídas em 27 gêneros, sendo que a família Termitidae foi a mais freqüente. A fauna de Isoptera foi mais rica na mata primária. A partir das coletas "quantitativas", foram registradas 19 espécies, e através das coletas "qualitativas", 33 espécies. A maioria das espécies encontradas é xilófaga.

The Atlantic Forest is considered one of the most diverse biome in the World, harboring a large number of endemic species. However, it is one of the most degraded ecosystems in Brazil; less than 8% of its original vegetation has been preserved. In southeastern part of the state of Bahia, irresponsible deforestation and misuse of land have being degrading the forest. In this area, the termite fauna is poorly known and there was no available survey. This paper aimed: 1) to carry out a first survey on the Isoptera from this region of the Atlantic Forest; 2) to compare the termite richness between primary and secondary forests using two kind of collecting protocols; 3) to compare the results from the two different collecting protocols; 4) to classify the species into trophic groups. The study areas are "Mata da Esperança" (primary forest) and "Reserva Zoobotânica da CEPLAC" (secondary forest), both in the county of Ilhéus, BA. Quantitative and qualitative surveys followed standard protocols and the samples were obtained directly, without baits. Thirty-eight species within twenty-seven genera were identified and the family Termitidae was the most frequent. The termite fauna of the primary forest was the richest. Nineteen and thirty-three species were registered with the quantitative and qualitative protocol, respectively. The majority of the species was classified as xilophagous.
