“…Las 14 especies de formícidos que se han estudiado tienen diversas categorías de distribución geográfica (nativas, exóticas, introducidas, etc.) (Janicki et al, 2016), destacando: Linepithema humile y Solenopsis invicta como hormigas introducidas y/o exóticas; las cuales han invadido casi todos los continentes, provocado daños en ecosistemas y pérdidas económicas para el hombre (Angulo et al, 2022;Chen et al, 2020;Seko et al, 2021).…”

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.

“…However, the reproductive capacity of a species is a complex phenotype, which depends on its genetics, reproductive development and physiology. In many organisms, reproductive development and physiology are not static traits (10). Remarkably, there is limited research investigating whether populations of an invasive species differ in their reproductive development and physiology, resulting in population differences in their overall reproductive capacity that could influence their invasive success (9) The Asian tiger mosquito Aedes albopictus (Skuse, 1894) is the archetype of a successful invasive species.…”

The understanding of traits favoring biological invasions has been considered an essential step to predict which species would become successful invaders. Classical approaches test for differences between invasive vs. not invasive species and emphasize reproduction as a critical phenotype for successful establishment of an invasive species. However, cross-species comparisons underestimate intraspecies differences, which may be relevant in invasive species with highly genetically diverse populations. Here we capitalize on the well-characterized invasion history of the arboviral vectorAedes albopictus, which resulted in genetically-distinct native, old and invasive populations, and compared the reproductive capacity (fertility and fecundity), development (timing of egg development, oviposition patterns and egg hatching) and physiology (blood digestion and nutrient movement during oogenesis) across populations. We observed that invasive mosquitoes optimize their nutrient investment during development and oogenesis, which leads to increased egg production with respect to native and long adapted laboratory mosquitoes. This higher fecundity results from a delay in oogenesis and is accompanied by higher fertility. We further tested inheritance of reproductive traits via reciprocal crosses, which showed a higher fertility and fecundity in hybrids with respect to parental strains and a potential contribution of males to the reproductive success of invasive mosquitoes. Our results provide evidence that resource allocation during development and oogenesis influences the reproductive capacity ofAe. albopictusand manifests in population differences that correlate with their invasion success.Significance StatementIn addition to being an essential process to ensure the survival of a species, reproduction is a key determinant for a species invasion success because it facilitates a species’ ability to establish in a new area. Reproduction is a complex phenotype that relies on intricate and timely interactions between genetic and physiological factors. Here we combined molecular, biochemical, and genetic approaches to show that efficient allocation of energetic resources during development and oogenesis fosters the reproductive output ofAe. albopictusmosquitoes and manifests as variation in the reproductive capacity of its geographic populations. These results are critical for predicting the invasion success of this species and tailoring effective control strategies.

The variability of iridomyrmecin, the venom of the Argentine ant, in its native and invasive ranges

et al. 2023

The Argentine ant is one of the five worst invasive ants. Recently it has been shown that one of the main compounds of its pygidial gland, iridomyrmecin, is used as a venom against competitors and enemies. Here, we explore the variability in the quantities of iridomyrmecin of individual workers, along a range of locations pertaining to both its native and invasive ranges, in order to know whether its venom could have contributed to the differential invasion success of European supercolonies. We specifically compared the amount of iridomyrmecin among supercolonies in the native range and among three invasive supercolonies: the Main supercolony (the most extended worldwide), the Corsican and the Catalonian supercolonies (both with a restricted distribution in Europe). Our main result is that the variability of the iridomyrmecin is very high. Looking at mean values, we found that the amount of iridomyrmecin of the Main supercolony was the lowest while the highest corresponded to the Corsican supercolony, with the Catalonian and the native range supercolonies having intermediate values. However, variability in the values within each supercolony was similar between supercolonies. This suggests that the success of a given invasive supercolony may not be explained by higher quantities of this defensive compound. Our results open the way for exploring the connection between defensive compounds and the invasion success of this global invader.
