Was performed a diagnosis to identify the species of the Scarabaeidae family present in guava cultivation, to determine the distribution and ecological indices of abundance and relative frequency of species associated with the cultivation. The sampling was carried out by light traps, in 35 fields of guava, in five Basic Units of Production and a small property, all belonging to the Ceballos Agroindustrial Enterprise, between May 2013 and June 2015. It was determined that the species of the Scarabaeidae family associated with the cultivation, were Cyclocephala cubana Chap., Phyllophaga patruelis Chev. Phyllophaga puberula Duval, Phyllophaga pilositarsis Blackwelder, Anomala calceata Chev., Strategus sarpedon Burm., Digitonthophagus gazella Fabricius and Dyscinetus picipes Burm. The most abundant species were C. cubana Chap. 60% (very abundant) and A. calceata Chev. with 10% (abundant). The species C. cubana, P. patruelis, P. puberula, P. pilositarsis, A. calceata and S. sarpedon, were very frequent, while D. gazella and D. picipes were frequent in guava cultivation.

Diferentes grupos de insectos se consideran importantes elementos bioindicadores de la calidad de los ecosistemas, los coleópteros son hoy en día uno de los grupos más reconocidos y utilizados para el monitoreo y establecimiento de áreas protegidas. Se evaluó el uso de la superfamilia Scarabaeoidea como bioindicador del grado de perturbación antropogénica de los bosques húmedos amazónicos. En tres niveles de perturbación (alta, media y baja) se establecieron 12 transectos, utilizando tres trampas de interceptación, dos trampas de luz, tres trampas de caída, cuatro trampas de botella y captura manual. Se capturaron 593 individuos, 92 especies, 44 géneros y 7 familias. Las familias con el mayor número de individuos y especies fueron Scarabaeidae (n=232, 27 spp.) y Dynastidae (n=161, 26 spp.). Las especies más abundantes fueron: Ateuchus sp., Cyclocephala verticalis, Ceratocanthus amazonicus y Chaetodus asuai. El número de especies e individuos fue mayor a medida que el gradiente de perturbación aumentó. Dynastidae presenta el mayor número de especies exclusivas mientras Scarabaeidae comparte la mayoría. Diez especies fueron registradas en los tres bosques, 26 en dos y 56 en solo uno. De las especies más abundantes C. asuai muestra una reducción significativa del número de individuos con el aumento de la perturbación, mientras se observa una relación inversa para C. verticalis. Se discute la utilización de la riqueza y la diversidad como indicadores de perturbación, mientras se ratifica la abundancia de ciertos táxones como una mejor variable a medir.

A study of the scarab beetles fauna of Huehuetitla canyon, in Tlaxcala state, Mexico is presented. Samples were obtained from August 2008 to December 2009 in Juniperus forest and secondary vegetation located at elevation of 2,600 m. We obtained 2,751 specimens than represent five families, seven subfamilies and 23 species of the following genera: Phyllophaga, Diplotaxis, Cyclocephala, Orizabus, Lygirus, Xyloryctes, Chrysina, Paranomala, Cotinis, Euphoria, Eucanthus, Labarrus, Cephalocyclus, Liothorax, Gonaphodiellus and Trox. The genus with the highest number of species was Phyllophaga (5 spp.), while Cephalocyclus fuliginosus was the most abundant specie with the 50.4% of the total sample. In addition, by mean of Parsimony Analysis of Endemism the relationship with other regional faunas is presented, where Huehuetitla canyon is grouped together with the faunas of Michilía, Durango and Villa de Allende, Estado de México. Its generic composition has a predominance of elements belonging to Paleoamerican pattern followed by elements of the Mexican Plateau. [ABSTRACT FROM AUTHOR]

The knowledge of the diversity of scarabs in Colombia in some areas is still very little studied, in order to extend this information the fauna of Scarabaeidae (Pleurosticti) of the lowlands of the tropical rain forest of the Choco-Biogeografico zone was characterized, durng the years 2001-2003. Five sampling sites with different composition and degrees of intervention were selected (primary forest, secondary forest, high stubble and agroforestal parcels), corresponding to the municipalities of ltsmina, Lloro, Quibdo, Todo and Union Panamericana, located between the 43 and 150 meters. The capture of the scarabs was made manually and with the use of nets, black light and modified coke-traps, rotten trunk of Brosimum utile H. B.K, Lecythis ampla Miers, Pouteria caimito Radlk, Apeiba aspera Aubl., lnga spp., Cedrela odorata L. and Jacaranda hesperi Dugand among others were explored. A total of 17,840 specimens in 65 species, distributed in 4 subfamilies, 12 tribes and 38 genera were collected. Pelidnota chiriquina Bates, Spodochlamys cupreola Bates, Gymnetis pardalis (G & P), Gymnetis vandepolli (Bates), Hoplopyga ocellata (G & P) and Guatemalica hueti (Chevrolat) are record for Colombia for the first time. The richest subfamily in number of species was Dynastinae with 26 species, followed of Rutelinae with 25, Cetoniinae with 11 and Melolonthinae with 3 species. The richest genera were: Cyclocephala Dejean, 1821: C. amazona (Linne), C. carbonaria Arrow, C. melanocephala (Fabricius), C. pardolocarrnoi Dechambe y C. fulgurata Burmeister; Anomala Samouelle. 1819: Anomala cincta Say, A. medellina Ohaus, A. undulata Melsheimer; Gymnetis MacLeay, 1819: Gymnetis coturnix (Burmeister), G. stellata (Latreille), G. holosericea (Voet) and Rutela Latreille, 1802: Rutela heraldica Perty, R. pygidialis Ohaus y R. sanguinolenta Waterhouse. A taxonomic key to identify the 65 species gathered is included. Biological and ecological comments for these species are also provided. [ABSTRACT FROM AUTHOR]

En el presente trabajo se determinó la riqueza de especies de escarabajos coprófagos en tres remanentes boscosos en tres áreas con condiciones ecológicas distintas: bosque primario maduro, fragmentos de bosque dentro de áreas agropecuarias y zonas deforestadas dentro de la Reserva Forestal Natural de Vanguardia en el municipio de Villavicencio. En cada una de las tres zonas definidas se hicieron tres muestreos en diferentes fechas, que consistieron en diez trampas de caída, 5 cebadas con heces de vaca intercaladas con 5 con heces humanas, dispuestas cada 100 metros en un transecto de un kilómetro de longitud. Los individuos recolectados se identificaron hasta género. Se calcularon índices de riqueza biológica como Chao y Jackknife, índices de diversidad y dominancia como Shannon-Wierner y Simpson para calcular la variedad de géneros en el área de estudio; de igual forma se identificó la relación y similitud de las muestras mediante el índice de Jaccard. Del esfuerzo de muestreo se logró colectar 194 individuos pertenecientes a 14 géneros de la familia Scarabaeidae que representa entre el 82 y el 100% de los géneros presentes en el área de acuerdo a los estimados de Jacknife y Chao respectivamente. Se encontró que en el bosque primario y en los fragmentos los 14 géneros y los indicadores mostraron una alta riqueza de especies y baja dominancia. En la zona deforestada solamente se encontraron tres de los 14 géneros y los indicadores mostraron una baja riqueza de especies, pero una alta dominancia. En las zonas forestadas se encontraron en abundancia los géneros Gromphas y Eurysternus que son típicas de bosques en buen estado, el número de capturas fue significativamente mayor en la zona de bosque primario extenso que en la zona de bosque fragmentado, estos géneros no fueron encontrados en las zonas deforestadas. Sylvicanthon, que es un género que se adapta mejor a todo tipo de condición, fue encontrado tanto en las zonas forestadas como en las deforestadas. Se encontró que todos los géneros fueron colectados en trampas cebadas con heces de vaca o de humano; sin embargo, en las trampas con heces humanas el número de individuos capturados fue mucho mayor. In the present work, the richness of coprophagous beetle species in remnant forest was determined at one area with different ecological conditions: primary old forest, fragmented forest and deforested areas within the Vanguardia Natural Forest Reserve at Villavicencio´s City. In each of them we made three samples, each sample consisted of a transect of 1 km, with pitfall traps, baited with cow and human feces, and in each transect five traps used cow feces and five with Human stool; those traps were interspersed. The collected specimens will be identified until gender level. Wealth indices such as Chao and Jackknife are calculated, indices of diversity and dominance such as Shannon-Wierner and Simpson to calculate the variety of genres in the study area; similarly, the relationship and similarity of the samples is identified through the Jaccard index. The sampling effort was divided to collect 194 specimens belonging to 14 genders of the Scarabaeidae family that represents between 82 and 100% of the genera present in the area according to the estimates of Jacknife and Chao, respectively. It was found that in the primary old forest and at fragmented forest. At deforested area we just found three of the 14 genders and indicators of low species richness, but higher dominance. In the forested areas, the genders called Gromphas and Eurysternus, which are typical in places with good conditions; Those genders were found in abundance, the number of catches became the area of extensive primary forest, and in the zone of fragmented forest, these genders were not found. Sylvicanthon, which is a genus that best adapts to all types of conditions, has been found in all of the areas. It was found that all of genders were collected in traps with cow or human feces; However, in the traps with the number of individuals captured was much more important.

Pentodontini es la tribu de dynastinos más diversificada y la mayoría de sus especies están restringidas a una única región geográfica. Sin embargo su validez taxonómica ha sido bastante debatida y existen dificultades para la diferenciación de algunos de sus géneros y especies. En el presente trabajo se determinó la composición taxonómica de la tribu Pentodontini en Colombia, se diagnosticaron los géneros y especies con base en los caracteres de la morfología externa y los genitales masculinos, se discutió la significancia de los caracteres tradicionalmente utilizados, y se analizó la distribución geográfica del grupo en el país. Se revisaron colecciones entomológicas colombianas con el fin de determinar los especímenes, realizar montajes, estudiar los caracteres taxonómicos y obtener registros de la distribución y biología de las especies. La fauna de pentodontinos en Colombia está representada por siete géneros y 24 especies. Se validan y corrigen registros de distribución para el país y se discuten posibles cambios en la nomenclatura taxonómica de algunas especies que deberían ser consideradas sinónimos de otras (Pucaya punctata, Denhezia caucacola, Tomarus discrepans). Se encontró una especie nueva del género Tomarus y cuatro más (Tomarus cicatricosus, T. cuniculus, T. pullus y Oxyligyrus contractus) se registran por primera vez en el territorio colombiano. Se incluyen claves taxonómicas para la identificación de los géneros y las especies, y fotografías e ilustraciones de los caracteres diagnósticos. Aunque la forma de los parámeros y del spiculum gastrale fueron los caracteres más importantes para diagnosticar las especies, estos deben ser combinados con los de la morfología externa. Abstract. Pentodontini is the most diverse tribe of Dynastinae, and most species are restricted to a single biogeographic region. However, its taxonomic validity has been debated and there are difficulties differentiating some genera and species. In this work, the taxonomic composition of the tribe in Colombia was determined, genera and species were diagnosed based on external morphology and male genitalia, significance of traditionally used characters was evaluated, and geographic distribution of the group within Colombia was analyzed. Entomological collections were visited to identify specimens, study taxonomical characters, and obtain records of distribution and biology of the species. In Colombia, Pentodontini are represented by seven genera and 24 species. Distributional records for Colombia are corrected and validated, and possible changes in the taxonomic nomenclature of some species, which should be considered as synonims (Pucaya punctata, Denhezia caucacola, Tomarus discrepans) are discussed. A new Tomarus species was discovered and four more (Tomarus cicatricosus, T. cuniculus, T. pullus and Oxyligyrus contractus) are recorded for the first time in Colombian territory. Taxonomic keys to genera and species and photographs and illustrations of diagnostic characters are included. Although shape of the parameres and spiculum gastrale were the most valuable characters for diagnosing species, they should be combined with those of external morphology. Maestría

Insects have been recognized to be important indicators of the quality elements of ecosystems, among others, because of their rapid response to environmental variability and ease cost-effective capture. In this work we evaluated whether beetles of the Scarabaeoidea superfamily may be used as bioindicators of anthropogenic disturbance of Amazonian terra firme rain forests, in order to provide guidelines for monitoring strategies of the Amacayacu National Park. We considered three different levels of anthropogenic disturbance (i.e. low, medium, high) in 12 transects (four in each intervention level), and caught all beetle species of this superfamily. Three interception traps, two light traps, three pitfalls and four bottle fruit traps were used per transect, as well as manual catch. In total, 593 individuals belonging to 92 species, 44 genera and seven families were collected. Scarabaeidae (n=232, 27 spp.) and Dynastidae (n=161, 26 spp.) were the families with the highest number of individuals and species, while Aphodiidae, Cetoniidae and Geotrupidae exhibited the lowest. The most abundant species per family were Ateuchus sp. (33.2%) from Scarabaeidae, Cyclocephala verticalis (55.9%) from Dynastidae, Astaena sp. (75.8%) from Melolonthidae, Ceratocanthus amazonicus (66.7%) from Ceratocanthidae y Chaetodus asuai (96.8%) from Hybosoridae. Results showed that the number of species and individuals increased with the anthropogenic disturbance. The Margalef and Shannon indexes also revealed that the highest richness and equity occurred in the high-disturbed site, respectively. Dynastidae exhibited the highest number of exclusive species per gradient, while Scarabaeidae shared most of its species. Ten species were recorded in the three disturbance levels, 26 species in two and 56 species were exclusive to one level. The most abundant species Chaetodus asuai (Hybosoridae) presented a significant decrease in the number of individuals as disturbance increased, while an inverse relationship occurred for C. verticalis (Dynastidae). For Astaena sp. (Melolonthidae) and Ligyrus gyas (Dynastidae) a high number of individuals was recorded and were exclusive for one forest site (low and high disturbed forest, respectively). The complete superfamily cannot be used like a single bioindicator element because it displays, in a specific level, very different behaviors in each disturbance condition. We discuss the use of richness and diversity as indicators of disturbance, while we highlight abundance of particular taxa as a better metric for disturbance. Diferentes grupos de insectos se consideran importantes elementos bioindicadores de la calidad de los ecosistemas, los coleópteros son hoy en día uno de los grupos más reconocidos y utilizados para el monitoreo y establecimiento de áreas protegidas. Se evaluó el uso de la superfamilia Scarabaeoidea como bioindicador del grado de perturbación antropogénica de los bosques húmedos amazónicos. En tres niveles de perturbación (alta, media y baja) se establecieron 12 transectos, utilizando tres trampas de interceptación, dos trampas de luz, tres trampas de caída, cuatro trampas de botella y captura manual. Se capturaron 593 individuos, 92 especies, 44 géneros y 7 familias. Las familias con el mayor número de individuos y especies fueron Scarabaeidae (n=232, 27 spp.) y Dynastidae (n=161, 26 spp.). Las especies más abundantes fueron: Ateuchus sp., Cyclocephala verticalis, Ceratocanthus amazonicus y Chaetodus asuai. El número de especies e individuos fue mayor a medida que el gradiente de perturbación aumentó. Dynastidae presenta el mayor número de especies exclusivas mientras Scarabaeidae comparte la mayoría. Diez especies fueron registradas en los tres bosques, 26 en dos y 56 en solo uno. De las especies más abundantes C. asuai muestra una reducción significativa del número de individuos con el aumento de la perturbación, mientras se observa una relación inversa para C. verticalis. Se discute la utilización de la riqueza y la diversidad como indicadores de perturbación, mientras se ratifica la abundancia de ciertos táxones como una mejor variable a medir.

Se realizó la revisión de los estados de larvas, pupas y adultos colectados en muestreos en suelos provenientes de cultivos de pasto y cultivos en el municipio de Guaitarilla en el departamento de Narino, y de la revisión de especímenes colectados en el municipio de Rionegro y El Retiro en el altiplano oriente de Antioquia. Las colectas de adultos se realizaron en los meses de noviembre de 2007 y abril de 2008 y de larvas de tercer instar, pupas y adultos en el mes de febrero de 2009. Después de la captura en cada uno de los sitios se fijaron los estados larval y pupal, en solución pampel. Los adultos fueron dispuestos en alfileres y se extrajo el edeago del macho para su análisis posterior en el laboratorio. Para la identificación de las especies se siguió la revisión de caracteres morfológicos sugeridos por Ritcher (1966) y Pardo et al (2007), y se generó una matriz comparativa revisando todas las partes del cuerpo en cada uno de los estados. Los resultados obtenidos permitieron determinar las siguientes especies: para el altiplano antioqueño, Astaena pigydialis Moser, para el altiplano nariñense, Astaena nitidula Moser, ambas consideradas nuevos registros de importancia agrícola para el complejo chisa de Colombia. Se describieron las larvas, pupas y adultos, aportando datos sobre crecimiento en condiciones de laboratorio. / Abstract: Astaena Erichson (Coleoptera: Melolonthidae) it has been considered to be one of the chisas with agricultural importance both by the quantity of individuals and for the damage that it realizes in farmings of the Colombian plateaus. Trying to establish what the species of present Astaena sp were in the plateaus of Nariño and Antioquia, and the morphologic differences between the states of larval and pupa. There was realized the review of the specimens collected in soils provenientes of farmings and of grasslands in the municipalities of Guaitarilla, Rionegro and the Retiro, respectively. The collections of third-instar larva and pupa were realized in November, 2007 and April, 2008, February, 2009. After the apprehension, the state larvae and pupal was fixed, in solution pampel for his later analysis in the laboratory. For the identification of the species there followed the review of morphologic characters suggested by Ritcher (1966) and Pardo-Locarno et to (2007), and a comparative counterfoil was generated checking all the parts of the body in each of the states. The obtained results allowed to determine the following species: for the antioqueño plateau, Astaena pigydialis Moser, for the nariñense plateau, Astaena nitidula Moser, both considered new records of agricultural importance for the complex chisa of Colombia.

From 1987 to 2000, great embryo and hatchling mortality (>70%) of sea turtles (Lepidochelys) has been reported in the nesting beach La Escobilla, Oaxaca, México. The embryo death in this beach was attributed by some authors mainly to the egg predation by a beetle belonging to the family Trogidae. Taxonomic examination confirmed that the beetle at La Escobilla was Omorgus suberosus Fabricius. This species has been also reported in some other nesting beaches of the Pacific, but in none of the Atlantic Ocean. The present paper, based on the literature published about both Omorgus and marine turtles (Lepidochelys), describes the interaction between Omorgus and sea turtles, and discusses the predatory role of Omorgus suberosus. Based in our research, there was insufficient evidence to point O. suberosus as a predator especialist in turtle eggs; the beetle seems to be a highly efficient and facultative necrophagous-saprophagous organism.
