“…La feromona 3-ethyl-2,5-dimethylpyrazine del grupo funcional amina fue el de cadena más corta (C05), utilizada en los experimentos con Myrmca rubra (Chalissery et al, 2019). En contraste, el hidrocarburo de cadena más larga fue Trishomofarnesene en los bioensayos con Cyphomyrmex rimosus y Cyphomyrmex salvini (C18) (Hamilton et al, 2018) (Figura 1). Los compuestos orgánicos más utilizados fueron hidrocarburos con cadenas de C12, C15, C16, C17 y C18 representando el 34.8%, seguido de ésteres cíclicos y cetonas (C06, C08 y C07, C10) con el 13% (Figura 1).…”

Las hormigas son himenópteros muy diversos y de amplia distribución geográfica. Son insectos sociales y su comunicación se basa en señales químicas. Dentro del grupo de semioquímicos que regulan la búsqueda de alimentos están las feromonas de rastro en los caminos. El propósito de esta revisión es documentar las principales feromonas de seguimiento en los senderos que guían a las hormigas hacia las fuentes de alimentación. Se realizó una revisión sistemática basada en las directrices de la declaratoria PRISMA de las investigaciones encontradas en PubMed, Web of Science y Google Scholar de las feromonas de rastro. Se reportaron 26 compuestos químicos de 14 especies de hormigas, las principales fuentes de obtención fueron extractos de cuerpo completo, abdomen y glándulas. La detección de los semioquímicos fueron respuestas electrofisiológicas de los himenópteros y métodos cromatográficos, registrando compuestos orgánicos de cadena corta y larga (C05-C18). El estudio de compuestos químicos de rastro se ha realizado a un número reducido de especies, este tipo de investigaciones tiene gran potencial para el control de hormigas invasoras, ya que su distribución ha tenido repercusiones negativas en los ecosistemas y daños económicos para el hombre. Palabras clave: Cromatografía de gases-espectrometría de masas, electroantenografía, glándulas, bioensayo, sendero.

“…Determination of the key compounds, and their physiological and behavioral effects, will provide a foundation for comparative studies (e.g., Ngumbi and Fadamiro, 2015). Such studies will clarify the evolutionary trajectories of specific compounds (Norman et al, 2017;Brückner et al, 2018;Hamilton et al, 2018) and improve our understanding of their perception by ant associates. Finally, an evolutionary approach to ant chemistry and eavesdropping will provide a basis for understanding how eavesdroppers and other ant associates, can shape the evolution of pheromone profiles.…”

“…If nest disturbance attracts the wasps or induces the emergence of adults, then these individuals could be collected and used in trials with host ant pheromones to test for eavesdropping. The alarm pheromone, 1-octen-3-ol, produced by Cyphomyrmex rimosus and Trachymyrmex cornetzi (Norman et al, 2017;Hamilton et al, 2018) may be a good compound to explore first. Additionally, the chemical ecology of fungus-growing attine ants has recently expanded (Hogan et al, 2017;Norman et al, 2017;Hamilton et al, 2018) and the phylogenetic relationships within the Attina subtribe are well understood (Branstetter et al, 2017), therefore this lineage of host ants offers great experimental potential for the identification of parasitoid attractants.…”

Interspecific Eavesdropping on Ant Chemical Communication

Chemical communication is a fundamental, highly complex component of social insect societies. Ants in particular employ a remarkable diversity of chemical signals to maintain social cohesion among nestmates, gain essential resources through coordinated foraging, and warn of danger. Although the chemicals used can be functionally specific, they are vulnerable to exploitation by eavesdropping natural enemies (e.g., parasitoids, predators, parasites) and other associates (e.g., myrmecophiles). Ant nests are nutrient hotspots due to their collection of resources warranting keen defense systems; yet the heavily defended hideouts are frequently invaded. Many organisms exploit ant species, but how they locate hosts-including what host-derived cues are used-is still poorly understood. Here, we review current knowledge about how ant chemical communication systems can be exploited by unintended receivers. We take a case study approach and illustrate the diversity of ant associates and host traits that may predispose ants to exploitation. We identify knowledge gaps by reviewing host systems and listing: (1) the types of associates (e.g., fly, wasp, beetle) where eavesdropping is likely occurring, organized by the host communication system that is being exploited; (2) the ant parasites that exploit trail pheromones; and (3) the experimentally determined chemicals (i.e., alarm/defensive pheromones), used by eavesdroppers. At least 25 families of arthropods (10 orders) potentially eavesdrop on ant communication systems and nearly 20 host ant species are vulnerable to trail parasite ant species. We also propose future research that will improve our understanding of community assembly by examining host traits (e.g., latitude, nest characteristics, trail system) that influence their susceptibility to eavesdropping associates.

The fungus-growing ant Mycetomoellerius (previously Trachymyrmex) zeteki (Weber 1940) has been the focus of a wide range of studies examining symbiotic partners, garden pathogens, mating frequencies, and genomics. This is in part due to the ease of collecting colonies from creek embankments and its high abundance in the Panama Canal region. The original description was based on samples collected on Barro Colorado Island (BCI), Panama. However, most subsequent studies have sampled populations on the mainland 15 km southeast of BCI. Herein we show that two sibling ant species live in sympatry on the mainland: Mycetomoellerius mikromelanos Cardenas, Schultz, & Adams and M. zeteki. This distinction was originally based on behavioral differences of workers in the field and on queen morphology (M. mikromelanos workers and queens are smaller and black while those of M. zeteki are larger and red). Authors frequently refer to either species as “M. cf. zeteki,” indicating uncertainty about identity. We used an integrative taxonomic approach to resolve this, examining worker behavior, chemical profiles of worker volatiles, molecular markers, and morphology of all castes. For the latter, we used conventional taxonomic indicators from nine measurements, six extrapolated indices, and morphological characters. We document a new observation of a Diapriinae (Hymenoptera: Diapriidae) parasitoid wasp parasitizing M. zeteki. Finally, we discuss the importance of vouchering in dependable, accessible museum collections and provide a table of previously published papers to clarify the usage of the name T. zeteki. We found that most reports of M. zeteki or M. cf. zeteki—including a genome—actually refer to the new species M. mikromelanos.
