“…Estos dípte-ros deben superar una serie de barreras físicas y de comportamiento que imponen sus hospederos para poder alcanzar el éxito reproductivo (Feener & Brown, 1997;Elizalde & Folgarait, 2011); características que son cruciales en el entendimiento de las interacciones a nivel ecológico (Elizalde, 2009). De estas moscas parasitoides se conoce que afectan varias especies de hormigas de los géneros Atta y Acromyrmex, pero poco se sabe sobre la biología y ecología de estas interacciones (Brown, 1997), por lo cual se desconoce qué tan significativa es la importancia de estos parasitoides.…”

“…Entre los diferentes efectos que pueden provocar sobre las hormigas cortadoras de hoja, se encuentra la disminución del reclutamiento hacia las fuentes de forrajeo, disminución en el tamaño de los fragmentos transportados hacia la colonia, pérdida de interacciones competitivas por la comida e, incluso, el abandono de las fuentes de alimento (Feener & Moss, 1990;Folgarait, 2013). También, se puede estimular el despliegue de posturas defensivas de protección con el cuerpo y la asociación con pequeñas hormigas compañeras sobre las cargas que impiden el ataque de los fóridos (Feener & Moss 1990, Elizalde, 2009Elizalde & Folgarait, 2011).…”

Behavioral patterns of parasitoid phorids (Diptera: Phoridae) of Atta colombica (Hymenoptera: Formicidae). In ecology, the success of parasitoid-host interactions is determined by the behavior of seeking, recognition, attack and defense deployed by the participants in the interaction. Our study aimed to understand the behavioral patterns between parasitoid phorids and their host Atta colombica from a forest fragment of Córdoba department, Colombia. We observed three nests of Atta colombica, from December 2013 to Januray 2015 (including dry and rainy seasons), for a total effort of 189 hours. We observed Phorids, their attacks to ants and collected their loads; we also considered differences in the way the parasitoids attacked and observed the microhabitat they preferred. A total of 52 individuals of Eibesfeldtphora attae and 54 of Apocephalus colombicus were collected. Apparently there was no preference for the size of the ants that were attacked by phorids, but larger loads were selected to land on them. When the ants responded to the phorid attack, they used individual defenses (adopting positions or increasing their speed) or grupal defenses (closer ants attacking the phorid). Parasitoid phorids have specialized their behavior, in order to ensure a successful attack on their host, who responded by modifying its behavior, according to the attacker (parasitoid). Rev. Biol.

“…Therefore, alternative methods of pest control have received increased attention, with researchers focusing mainly on biological control either by microorganisms or by other insects (Montoya Lerma et al, 2012;Della Lucia et al, 2014). Amongst the latter, the flies in the family Phoridae have been proposed as promising candidates for biological control of leafcutter ants (Folgarait, 2013) because of two main reasons: their high specificity (Elizalde & Folgarait, 2011) and the indirect effects they have on their hosts, which widely exceed the mortality they inflict (Elizalde & Folgarait, 2012;Guillade & Folgarait, 2014). Research on leafcutter ant phorids in Argentina is relatively new, and therefore the information on their distribution and the ant species they attack is still somewhat limited (Folgarait, 2013;Elizalde et al, 2017).…”

“…Every nest sampled was geo-referenced and the ants identified to the species level following the keys by Gonçalves (1961) and Kusnezov (1978). Samplings were carried out through the Larval Parasitoid Collection method (Elizalde & Folgarait, 2011), which consists in collecting every ant that passes a fixed point in the foraging trail returning to the nest, until between 300 and 500 ants have been caught. Ants were then transported to the laboratory and kept in climatically controlled chambers at 24 °C and 70% RH, which according to Guillade & Folgarait (2015) are the optimal rearing conditions for leafcutter ant parasitoids.…”

Las hormigas cortadoras de hojas son una de las plagas más importantes de la región Neotropical. En el presente estudio, fueron recolectados representantes de cuatro provincias de Argentina, con el objetivo de identificar las especies de fóridos que las parasitan. Como resultado, se registraron siete especies de fóridos, Apocephalus neivai Borgmeier, Ap. noetingerorum Disney, Neodohrniphora unichaeta Disney, Myrmosicarius catharinensis Borgmeier, M. cristobalensis Disney, M. crudelis Borgmeier y M. gracilipes Borgmeier, obtenidos en hormigas cortadoras de hojas de las especies Acromyrmex ambiguus Emery, Ac. crassispinus Forel, Ac. heyeri Forel, Ac. lobicornis Emery y Ac. lundii Guérin. Asimismo, son reportados todos los registros previos de hospedadores y su distribución geográfica en Argentina para las siete especies de fóridos. Se citan nuevos registros en todas las especies estudiadas, ampliando así sus rangos geográficos y estableciendo once nuevas interacciones hospedador-parasitoide. Nuestros datos amplían el conocimiento de este poco estudiado sistema y proveen importantes consideraciones para el uso potencial de estos parasitoides como controladores biológicos de hormigas cortadoras de hojas.

In the present study, several specimens were collected from four provinces in Argentina in order to determine the species of phorid flies parasitizing them. We report our findings on seven phorid species, Apocephalus neivai Borgmeier, Ap. noetingerorum Disney, Neodohrniphora unichaeta Disney, Myrmosicarius catharinensis Borgmeier, M. cristobalensis Disney, M. crudelis Borgmeier and M. gracilipes Borgmeier, over the leafcutter ants Acromyrmex ambiguus Emery, Ac. crassispinus Forel, Ac. heyeri Forel, Ac. lobicornis Emery and Ac. lundii Guérin. All the known hosts and geographic ranges for these seven phorids in Argentina are provided. The seven phorid species represent new records for all the provinces studied, expanding their geographical ranges; furthermore, we establish a total of eleven new host-parasitoid interactions. Our data expand the knowledge of this little studied system and provide important considerations for the potential use of these parasitoids as biological control candidates of the leafcutter ants.

“…The phorid flies that parasitize ants use the host's body to complete their life cycle, and their occurrence is restricted by certain conditions, such as habitat structure, temperature and relative humidity (Folgarait et al 2007;Almeida et al 2008;Elizalde & Folgarait 2010). In addition, parasitoid abundance may depend on host foraging activity (Tonhasca Jr. 1996), and the form of attack or oviposition site (such as nest entrance holes or foraging trails) vary among phorid species (Erthal Jr. & Tonhasca Jr. 2000;Bragança & Medeiros 2006;Gazal et al 2009;Elizalde & Folgarait 2011, 2012. Recently, three species of phorid flies were described attacking workers of A. robusta, two of them were recorded only in Rio de Janeiro: Eibesfeldtphora breviloba Brown and Myrmosicarius exrobusta Brown (Brown et al 2012).…”

ABSTRACT. Parasitoids of the endangered leafcutter ant Atta robusta Borgmeier in urban and natural areas. Hosts of parasitoids in urban areas may suffer from a double threat of habitat destruction by urbanization and parasitism pressure. Moreover, the parasitoids themselves might be at risk if they are specialists. Here, we studied whether Atta robusta (Hymenoptera, Formicidae), which is on the red list of Brazilian threatened species, suffers from higher parasitism pressure in an urban area compared to a natural one. In addition, we determined whether their specialist parasitoids, Eibesfeldtphora breviloba and Myrmosicarius exrobusta (Diptera, Phoridae), are in risk and evaluated whether they are influenced by habitat structure, temperature, humidity, ant traffic, and time of the day. The study was carried out in an urban park and in a natural protected area in the city of Rio de Janeiro. In each site we chose an open area and a closed area (forest) and sampled nine nests in each area. We found that parasitism pressure was similar in urban and natural areas, with the same two parasitoid species present in both areas. The main difference was related to habitat structure, since M. exrobusta was mainly present in open areas while E. breviloba was almost exclusively found in closed areas. Myrmosicarius exrobusta was not present during the hottest midday times, and its abundance was negatively correlated to vapor pressure deficit. These results suggest that green areas can be an important component in efforts to conserve diversity in urban areas. However, the complexity of the habitats in those areas is a fundamental issue in designing urban parks.
