Species of Aphidiinae (Braconidae) have never been surveyed in Central America. Here we present the results of an initial inventory of the aphidiine species of Costa Rica and record the presence of ten species (four undetermined), in six genera. The material was obtained by rearing aphids from both crop and noncrop plants throughout the country. In total 2832 aphidiine specimens were reared from 24 species of aphids.Aphidius colemaniandLysiphlebus testaceipes, which are probably not native to Costa Rica, accounted for nearly 90% of all the specimens. Many of the other aphidiines are also probably exotic species, as are most of their host aphids.

Aphid parasitoids have been recorded in many countries around the globe, however records in Colombia are few. Here, five primary parasitoids species, Aphidius platensis Brèthes, 1913, Aphidius funebris Mackauer, 1961, Aphidius matricariae Haliday, 1834, Aphelinus varipes (Förster, 1841), Aphelinus paramali Zehavi & Rosen, 1989, and two hyperparasitoids species, Syrphophagus aphidivorus (Mayr, 1876) and Pachyneuron aphidis (Bouché, 1834) are newly recorded in Colombia. Two other primary parasitoids, Lysiphlebus testaceipes (Cresson, 1880) and Aphidius colemani Viereck, 1912 are newly recorded from the department of Valle del Cauca.

Host Habitat Location

AbstractA critical stage in the success of a parasitoid is the ability to locate a host within its habitat. It is hypothesized that a series of olfactory cues may be involved in altering the parasitoid's movement patterns at this stage of foraging. This paper focuses specifically on host habitat location and host location and the olfactory stimuli necessary to mediate the transition between these stages. Firstly, we confirm the ability of the parasitoid Aphidius colemani to detect the aphid sex pheromone at an electrophysiological level. Following this we investigate the effect of the sex pheromone component (4aS,7S,7aR)-nepetalactone on the movement patterns of A. colemani and its retention within an area. The key findings of this work are that A. colemani is able to detect the sex pheromone components, that parasitoid retention is increased by a synergy of nepetalactone and other host-associated cues and that foraging patterns are augmented by the presence of nepetalactone or experience associated with nepetalactone.

Para Determinar

El control de Myzus persicae Sulzer (Hemiptera: Aphididae) en la producción de duraznero, se lleva a cabo principalmente mediante el uso de insecticidas, cuyo uso indiscriminado puede causar diferentes efectos adversos en los agroecosistemas. Esta investigación presentó como objetivo principal: evaluar el empleo del sistema de Avena sativa-Rhopalosiphum padi-Aphidius colemani, como estrategia para el control biológico de M. persicae en el cultivo de P. persica por medio de la técnica de plantas refugio o banker plants. En una parcela comercial de duraznero en Junín (Prov. de Mendoza, Argentina), se realizaron muestreos para determinar las asociaciones planta-áfido-parasitoide en la vegetación aledaña al cultivo, en gramíneas del interfilar y en el monte frutal. En la vegetación aledaña, se relevaron 16 especies vegetales en las que se identificaron 13 especies de áfidos y siete especies de parasitoides primarios. El áfido dominante fue Aphis gossypii Glover mientras que Lysiphlebus testaceipes (Cresson) fue el parasitoide dominante. En relación a las gramíneas, se encontraron cinco especies de áfidos y seis de parasitoides primarios, Ropalosiphum maidis (Fitch) fue el áfido dominante y A. colemani el parasitoide dominante. En duraznero, la asociación M. persicae-A. colemani fue la más importante. Se evaluaron a campo tres estrategias de control: Insecticida (Imidacloprid 70% WP), Testigo y liberación de A. colemani a razón de 2 Momias/m2. El parasitoidismo natural aumentó mas del 30% en el segundo año de estudio registrando el testigo la mayor proporción de parasitoides secundarios. El tratamiento 2 Momias/m2 presentó, tasas superiores y un crecimiento más rápido del parasitoidismo de M. persicae respecto a los otros, revelando además valores similares al tratamiento con insecticida en relación al daño producido por M. persicae. La diversidad de parasitoides primarios medida por el Índice de Shannon-Wiener fue de 2,0452 para el tratamiento 2 Momias/m2, de 1,7824 para el Testigo y de 1,7201 para el Insecticida. El control biológico por medio del uso de plantas refugio se considera una alternativa viable para el control de la plaga M. persicae.

A summary of the study of Aphis illinoisensis Shimer on grapes, Vitis vinifera in the Mediterranean area brings references and new findings on its distribution in Crete/Greece, Turkey, Northern Cyprus, Malta, Israel, Montenegro, Tunisia, Algeria and Libya. Parasitoids of A. illinoisensis were only occasionally found (Aphidius matricariae Hal. - Cyprus, Turkey, Greece; Aphidius colemani Viereck - Libya; Lysiphlebus testaceipes Cress. - Algeria). Of the native species, i.e. A. colemani, and others similar to the native species, L. testaceipes seem to be a promising biocontrol agent within the framework of an ecologically friendly management in the area. Given the evidence of its expansion, A. illinoisensis is expected to expand further in several directions from the recently documented invaded area to all the grape-growing areas of the Mediterranean and even those of South-Eastern and Central Europe.

The interactions between aphids and their Hymenopteran parasitoids on irrigated oats as well as the response of different cultivars of cereals regarding the resistance to these aphids and the influence on the host/parasitoid relationships were studied during two years in São Carlos, Brazil. Rhopalosiphum padi (L.) was the predominant aphid observed throughout the study, while the other species were rarely found. Five species of parasitic Hymenoptera were found: three primary parasitoids, Lysiphlebus testaceipes (Cresson), Aphidius colemani (Viereck) and Diaeretiella rapae (M'Intosh) and two hyperparasitoids, Syrphophagus aphidivorus (Myer) and Alloxysta brassicae (Ashmead). The UPF 86081 cultivar presented significant results regarding lower Rhopalosiphum padi contamination and higher aphid parasitism rates than those observed on some other cultivars. No significant effect on the percentage variation of parasitoid emergence on the mummified aphids was observed throughout this study.
