Abstract: Twenty-six species of ants associated with aphids, belonging to twelve genera, are collected. Three subfamilies are identified, being the Formicinae the more represented about number of samples, genera and species. On the other hand, Lasius niger has been the species that is found with a more number of aphids (fifty eight species), and it seems to be the ant with a more capacity to establish associations with the different species of aphids. 224 different associations between the ants and the aphids are established and 164 of them are not recorded in the bibliography consulted for Spain. Se han recogido veintiséis especies de hormigas asociadas a pulgones, pertenecientes a doce géneros. De las tres subfamilias identificadas, Formicinae ha sido la más representada en cuanto a número de muestras, géneros y especies. Lasius niger, por otra parte, ha sido la especie que se ha encontrado junto a un mayor número de pulgones (cincuenta y ocho especies), demostrando ser la hormiga con mayor capacidad para establecer asociaciones con las diferentes especies de pulgones. Se han establecido un total de 224 asociaciones diferentes entre las hormigas y los áfidos, de las cuales 164 no se han encontrado citadas en la bibliografía consultada para Espa a.

Revista de la Sociedad Entomol?3gica Argentina , 2008,
Abstract: in 30 surveys across cordoba city and surroundings (argentina) i recorded, from november 2001 to may 2002, a total of 109 ornamental plants infested with aphid colonies. surveys were conducted in the local botanical garden as well as homestead gardens and nurseries. seventeen species of aphids were identified, 4 of which are new species in the area, from 47 ornamental plants. in a total of 59 plant/aphid associations, 38 new associations were found. i present the first record of aphids colonizing cactaceae in argentina. most aphid colonies were medium and a high proportion (more than 40%) showed alate individuals. the most frequent aphid species, aphis gossypii glover and aphis craccivora koch were especially associated with the most frequent damages: curled leaves or buds and necrosis, respectively. more than 30% of aphid colonies were attended by ants. camponotus mayr and prenolepis mayr were the ant genus attending the highest number of aphid species.

En 30 censos realizados en la ciudad de Córdoba y alrededores (Argentina) se registraron, entre noviembre de 2001 y mayo de 2002, un total de 109 plantas ornamentales infestadas de colonias de áfidos. Los censos fueron realizados en jardines, viveros y el jardín botánico de la ciudad. Se identificaron 47 especies de plantas ornamentales infestadas con 17 especies de áfidos (4 nuevas en el área). Se establecen 59 relaciones áfido/planta, de las cuales 38 son nuevas. Se obtuvo el primer registro de áfidos que colonizan Cactaceae en Argentina. La mayoría de las colonias de áfidos fueron medianas y una alta proporción (más del 40 %) mostró individuos alados. Aphis gossypii Glover y Aphis craccivora Koch, fueron las especies más frecuentes y generaban los da os más conspicuos, como el enrollamiento y la necrosis foliar. Más del 30% de las colonias estuvieron atendidas por hormigas, siendo Camponotus Mayr y Prenolepis Mayr los géneros de hormigas que frecuentaban el mayor número de especies de áfidos.

Abstract: Diez especies de áfidos (Hemiptera: Aphididae) se hallaron parasitados por siete especies de parasitoides (Hymenoptera: Braconidae, Aphidiinae) en cultivos hortícolas orgánicos. Myzus persicae (Sulzer) fue el áfido más frecuentemente encontrado sobre una amplia variedad de cultivos, y con mayor diversidad de parasitoides asociados. Aphidius colemani Viereck fue el afidiino más usual, que ataca varias especies de áfidos. Ocho asociaciones tritróficas, involucrando Aphidius matricariae Haliday, han sido registradas por primera vez para la Argentina. Ten aphid species (Hemiptera: Aphididae) were found parasitized by seven aphid parasitoid species (Hymenoptera: Braconidae, Aphidiinae) on organic vegetable crops. Myzus persicae (Sulzer) was the most frequent aphid found on a wide variety of crops, with the largest parasitoid diversity associated. Aphidius colemani Viereck was the most frequent aphidiine attacking several species of aphids. Eight tritrophic associations involving Aphidius matricariae Haliday are reported for the first time for Argentina.

Abstract: Los áfidos son insectos perjudiciales tanto por la succión de savia como por la transmisión de enfermedades. Los objetivos de este trabajo fueron conocer las especies de áfidos y sus parasitoides presentes en diferentes genotipos de garbanzo, calcular la incidencia del parasitismo e informar sobre las fluctuaciones poblacionales de pulgones y parasitoides en relación a los estados fenológicos del cultivo. El estudio se realizó durante 2006 y 2007 en San Marcos Sierras (Córdoba). Se evaluaron siete líneas y dos cultivares sembrados en un dise o en bloques completamente aleatorizados con tres repeticiones. Cada 15 días se colectaron manualmente áfidos y "momias" presentes en 10 plantas seleccionadas al azar, de cada genotipo y bloque. Se determinaron 13 especies de áfidos. En 2006 se observó mayor abundancia y riqueza de especies que en 2007. Las especies numéricamente dominantes fueron: Acyrthosiphon pisum y A. kondoi. Solamente cinco especies colonizaron el cultivo. El cultivar Cha aritos presentó la mayor abundancia de insectos en los dos a os agrícolas, y los genotipos M60 y M75 mostraron la mayor riqueza de especies. En ambos a os, los pulgones estuvieron presentes durante la etapa reproductiva del cultivo. Se registraron tres especies de parasitoides y se estimó un 35% de parasitismo total. Aphids may damage plants by sucking plant juices or by transmitting diseases. The aim of this study was to obtain further information about aphid species and their parasitoids in different genotypes of chickpea, calculate the incidence of parasitism and report on fluctuating populations (from aphids and parasitoid) in relation to plant phenology. The study was undertaken during 2006 and 2007 in San Marcos Sierras (Cordoba). Seven lines and two cultivars of chickpea were evaluated. Crop plots were planted following a completely randomized design block with 3 replicates. Every two weeks different developmental stages of aphids and "mummies" found in 10 plants randomly selected from each genotype and block were collected manually. Thirteen species of aphids were identified. In 2006 there was greater abundance and species richness than in 2007. The numerically dominant species were Acyrthosiphon pisum and A. kondoi. Only 5 species colonized the crop. Cha aritos presented the greatest abundance of insects in both years and M60 and M75 genotypes showed the greatest species richness. In both years, aphids were present during the reproductive stage. There were three species of parasitoids and parasitism was estimated at about 35%.

Abstract: the quality of the ornamental plants is closely related to their phytosanitary state, that, in turn, is affected by the activity of some insect groups. aphids are common pests of nearly all kinds of plants, ornamental plants among them. the fauna associated with aphids that colonize ornamental plants includes honey ants (hymenoptera: formicidae) that establish mutualistic relations, and some parasitoids (hymenoptera: braconidae, aphidiinae) that contribute to the control of the aphid population. very little is known about the aphids and their associated fauna living on ornamental plants of cordoba, argentina. the goal of this work was to identify the aphids that colonize ornamental plants, as well as their associated honey ants and parasitoids. samples of sprouts, leaves and/or flowers of aphid-colonized ornamental plants of the jardín botánico municipal of cordoba city were collected weekly, from october 2003 to november 2004. whenever found, the associated honey ants and "mummies" of aphids atacked by parasitoids were also collected. one hundred and thirty two aphid-plant associations were registered, 64.4% of which were unknown in the country. in 33.3% of these associations, the aphids were tended by honey ants whereas the presence of aphid parasitoids was registered in 16.7%. ninety five species of ornamental plants were colonized by 41 aphid species, whereas six ant species tended 10 aphid species. aphid parasitoids were represented by four species related to 11 aphid species.
