Biological collections store organisms and valuable information that can be used for biodiversity research. The Entomology Collection of the Natural History Museum of the Cauca University - MHNUC, Colombia, preserves a considerable number of specimens belonging to various orders of insects, among which the order Lepidoptera stands out. Lepidoptera...

Se revisaron 199 ejemplares de la familia Papilionidae depositados en la Colección de Entomología del Museo de Historia Natural de la Universidad del Cauca (MHN-UniCauca), Popayán, Cauca, Colombia. El material biológico ha sido recolectado por estudiantes, profesores e investigadores desde los años 1940s hasta la fecha. Se identificaron nueve géner...

El Patía, (Cauca, Colombia) es una zona caracterizada por ser vulnerable a intervenciones antrópicas y fenómenos naturales, lo cual motiva a realizar estudios que reflejen las dinámicas ecológicas empleando organismos indicadores biológicos como las mariposas. Esta investigación evaluó el efecto de la matriz ganadera sobre la comunidad de mariposas...

Resumen Con el fin de profundizar en el conocimiento de la herbivoría de la hormiga arriera (Atta cephalotes) en el bosque seco tropical, se estudió la actividad forrajera de 12 nidos situados en dos parches de bosque seco: seis en el Parque Natural Regional El Vínculo en el departamento del Valle del Cauca y seis en La Pachuca en el departamento d...

En dos fincas cafeteras localizadas en la vereda Villanueva, municipio de Popayán; Colombia, se identificó la comunidad de hormigas presentes en los nectarios extraflorales de árboles de guamo (Inga edulis e I. densiflora) utilizados como sombra en cafetales, y sobre la hojarasca del suelo. Las recolecciones se realizaron con cebos, extracción de h...

In the department of Cauca, still remains small fragments sub-Andean forest persist. The nature reserve "Raíces de Vida" (Roots of Life) of the school "Carmen Quintana", at Cajibío (Cauca), has one of these fragments but influenced by areas of agricultural uses. This prompted a need for investigate the actual state in order to define and, if needed...

The ant assemblages of a fragment of secondary tropical dry forest located in the Botanical Garden of Cali are presented. Two habitats were chosen: a fragment of forest and a pasture matrix. Samples were taken monthly for six months, using a linear transect of 100 m, with 10 stations spaced 10 m. At each station pitfall traps, epigeal bait and arbo...

Despite the numerous records of ant-mimicking arthropods, reports of ant species that are mimics among themselves are still rare. In the savannah of central Brazil we found two ant species that are remarkably similar in color pattern and body size, Pseudomyrmex termitarius and Camponotus blandus. Both species are widely distributed in the Neotropic...

In order to survey the ant fauna inhabiting termite nests of Cornitermes cumulans (Kollar) in the Cerrado sensu stricto of Central Brazil, we collected inquiline ants in 36 termitaries in three localities. Termite mounds were fragmented and the ants collected and preserved in 80% ethanol. Here we present a list of the associated ants found in mound...

It was evaluated the impact of intensifying coffee production and the agricultural management on ant diversity. The study was carried out in seven coffee farms under two different shade management systems: Polyculture (coffee with shading trees) and monoculture (coffee with no shading). Plant characterization for each coffee crop was done based on...

Las interacciones entre hormigas y otros insectos pueden afectar directa o indirectamente las plantas de café y su producción. El presente estudio tuvo como objetivo describir estas interacciones en cuatro plantaciones de café con y sin presencia de árboles de sombra, en el sitio Pescador (Caldono) departamento del Cauca. En cada plantación se sele...

Dung beetles (Coleoptera: Scarabaeoidea-Scarabaeinae) are saprophagous organisms that maintain stenotypic relations with forest environments, forming communities dependent of the conservation status and ecosystem management. Therefore, this research associated the structure variation, its richness and abundance on the habitat plots in the Clarete m...

The interactions between ants and other insects can directly or indirectly affect coffee plants and their production. The objective of this study was to describe these interactions in four coffee plantations, with and without the presence of shade trees, in the location of Pescador (Caldono), Cauca Department. At each plantation, 45 coffee bushes w...

Certain agroecological practices, such as implementing crops in agroforest systems favor biodiversity and, consequently the presence of certain biological control agents. Among these agents, predatory ants might play an important role for crop production. This study was intended to determine whether the presence of ants might affect coffee producti...

Soil-dwelling ants, many of which are generalist predators, are more diverse in shaded than in sun coffee plantations without trees. We compared ant predation on the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae) in three shaded and three sun coffee plantations in Apía, Colombia, in both the wet and the dr...
