Aphids are important insects in agronomy, due to their sap-sucking habits in cultivable plants. Their damages may generate economic losses and become lethal to plants, due to diseases produced by the viruses that several aphids transmit. Despite their importance, taxonomic inventories in the country are still incipient. Also, species studied in pre...
The aphids Takecallis taiwana (Takahashi, 1926) and T. arun-dinariae (Essig, 1917) were collected from two locations in the Department of Cundinamarca (Colombia) and one location within 90 km of the city of Bogota on plants of the Phyllostachys sp. (Poaceae: Bambusoideae). This represents the first record of these species from the northern half of...
The gall-forming aphid Tetraneura fusiformis is recorded for the first time for Northern South America. Its identity is clarified, and descriptions of this species and that of T. nigriabdomi-nalis, with which it is commonly confused, are offered. The association of this sap sucking insect with the ant Linepithema angulatum (Hymenoptera: Formicidae)...
El áfido Sipha flava (Hemiptera: Aphididae), se encontró en pasto kikuyo, Pennisetum clandestinum, en el norte de la Sabana de Bogotá y en el área urbana de Manizales. Se evaluó el daño ocasionado por su alimentación y las características de las colonias. El amarillamiento de la hoja presentó un valor máximo de 31,3 %/m². Las colonias de S. flava p...
The aphid Sipha flava was found on kikuyu grass, Pennisetum clandestinum, in the Northern Sabana of Bogota and Manizales urban area. We evaluated the damage caused due to the aphid's feeding habits and colonies characteristics. Symptoms of yellow leaves reached the maximum value of 31.3%/m². Colonies of S. flava preferred the upper leaf feeding and...

Aphids are succivorous, polyphagous insects that attack an important number of crops. Damages are of economic importance and may be lethal to plants since aphids are adapted to transmit different viruses, while sucking sap juices. Aphids live in symbiotic association with ants. Ants protect and move them from one place to another, and receive honey...

The crape myrtle aphid Sarucallis kahawaluokalani (Kirkaldy) (Hemiptera: Aphididae) collected on Lagerstroemia indica (Lythraceae) is herein reported as a new invasive species in the city of Palmira, State of Valle del Cauca, and on San Andres island, in the State of San Andres, Old Providence and Santa Catalina, Colombia. The species is illustrate...
Resumen Los áfidos son insectos polífagos succívoros y se alimentan de una importante cantidad de cultivos. Los daños son de importancia económica y pueden ser letales para las plantas, ya que los áfidos están adaptados para transmitir diferentes virus cuando chupan la savia. Viven también en asociación simbiótica con hormigas. Estas, a su vez, los...
