TL;DR: The results show cross-species application of known microsatellite loci is a highly promising source of codominant markers for population genetic and evolutionary studies in aphids.
Abstract: Despite the relative ease of isolating microsatellites, their development still requires substantial inputs of time, money and expertise For this reason there is considerable interest in using existing microsatellites on species from which markers were not cloned We tested cross-species amplification of 48 existing aphid loci in species of the following genera: Aphidinae: Aphidini: Aphis and Rhopalosiphum ; Aphidinae: Macrosiphini: Acyrthosiphum , Brevicoryne , Diuraphis , Illinoia , Macrosiphoniella , Macrosiphum , Metopeurum , Metapolophium , Myzus , Phorodon , Sitobion and Uroleucon and Neuquenaphidinae: Neuquenaphis Our results show cross-species application of known microsatellite loci is a highly promising source of codominant markers for population genetic and evolutionary studies in aphids

TL;DR: Collections of Uroleucon bereticum made throughout the National Park "Quebrada del Condorito" at Pampa de Achala, province of Cordoba, Argentina indicate the occurrence of new and more numerous oligophagous parasitoid guild in the target area.
Abstract: Collections of Uroleucon bereticum (E.E. Blanchard) on Conyza bonariensis (L.) Cronquist were made throughout the National Park "Quebrada del Condorito" at Pampa de Achala, province of Cordoba, Argentina. This aphid species was described as Macrosiphoniella beretica by Blanchard (1922) from apterous viviparous female and the alate viviparous female were unknown. Morphological characteristics of U. bereticum presented in this paper include the re-description of the apterous viviparous female as well as a new description of the alate viviparous female. Very little is known about the aphid parasitoids in Argentina and material of the indigenous endemic aphid species has not been collected up to now. Binodoxys achalensis Starý, sp.n. is described as a new endemic parasitoid species associated with U. bereticum and its seems to indicate the occurrence of new and more numerous oligophagous parasitoid guild in the target area.
