Polygynous Supercolonies of the Acacia-Ant Pseudomyrmex Peperi, an Inferior Colony Founder

Several plant–ants are polygynous. Possessing more than one queen per colony can reduce nestmate relatedness and consequently the inclusive fitness of workers. Here, we investigated the colony structure of the obligate acacia-ant Pseudo- myrmex peperi, which competes for nesting space with several congeneric and sympatric species. Pseudomyrmex peperi had a lower colony founding success than its congeners and thus, appears to be competitively inferior during the early stages of colony development. Aggression assays showed that P. peperi establishes distinct, but highly polygynous supercolonies, which can inhabit large clusters of host trees. Analysing queens, workers, males and virgin queens from two supercolonies with eight polymor- phic microsatellite markers revealed a maximum of three alleles per locus within a colony and, thus, high relatedness among nestmates. Colonies had probably been founded by one singly mated queen and supercolonies resulted from intranidal mating among colony-derived males and daughter queens. -

MOUND & ALICE WELLS Australian National Insect Collection CSIRO, PO Box 1700, Canberra, ACT 2601 [email protected] Abstract Drypetothrips korykis gen. et sp.n. is described as inducing leaf-margin galls on a small tree in Australia, Drypetes deplanchei [Putranjivaceae]. This thrips is similar in appearance to the smaller species of the genus Kladothrips that induce galls on Acacia species. The galls are invaded by a phytophagous kleptoparasitic thrips, Pharothrips hynnis gen. et sp.n., females of which have a forked plough-like structure protruding ventrally on the frons that is unique amongst Thysanoptera. Key words: autapomorphy, systematic relationships, leaf-margin galls, Australia Introduction The small tree, Drypetes deplanchei [Putranjivaceae], is widespread across northern Australia as far south as New- castle on the east coast. This tree is sometimes referred to as native holly, because the leaf margins can be sharply dentate, but these margins may also be almost smooth, and a species of thrips has been found inducing rolled margin galls on both leaf forms (Fig. 1). These galls and their thrips have been found at sites near Taree in coastal New South Wales, and also at Mt. Nebo near Brisbane in south-eastern Queensland. -
A Small Number of Workers with Specific Personality Traits Perform Tool Use in Ants Istva´ N Maa´ K1,2, Garyk Roelandt3, Patrizia D’Ettorre3,4*
RESEARCH ARTICLE A small number of workers with specific personality traits perform tool use in ants Istva´ n Maa´ k1,2, Garyk Roelandt3, Patrizia d’Ettorre3,4* 1Department of Ecology, University of Szeged, Szeged, Hungary; 2Museum and Institute of Zoology, Polish Academy of Science, Warsaw, Poland; 3Laboratory of Experimental and Comparative Ethology UR 4443, University Sorbonne Paris Nord, Villetaneuse, France; 4Institut Universitaire de France (IUF), Paris, France Abstract Ants use debris as tools to collect and transport liquid food to the nest. Previous studies showed that this behaviour is flexible whereby ants learn to use artificial material that is novel to them and select tools with optimal soaking properties. However, the process of tool use has not been studied at the individual level. We investigated whether workers specialise in tool use and whether there is a link between individual personality traits and tool use in the ant Aphaenogaster senilis. Only a small number of workers performed tool use and they did it repeatedly, although they also collected solid food. Personality predicted the probability to perform tool use: ants that showed higher exploratory activity and were more attracted to a prey in the personality tests became the new tool users when previous tool users were removed from the group. This suggests that, instead of extreme task specialisation, variation in personality traits within the colony may improve division of labour. Introduction Tool use is a widespread phenomenon within the animal kingdom (Shumaker et al., 2011; Sanz et al., 2013) and new examples of animal tool use are regularly discovered, such as recently in *For correspondence: [email protected] pigs (Root-Bernstein et al., 2019) and seabirds (Fayet et al., 2020). -

Bacterial endosymbionts are common across insects, but we often lack a deeper knowledge of their prevalence across most organisms. Next-generation sequencing approaches can characterize bacterial diversity associated with a host and at the same time facilitate the fast and simultaneous screening of infectious bacteria. In this study, we used 16S rRNA tag encoded amplicon pyrosequencing to survey bacterial communities of 310 samples representing 221 individuals, 176 colonies and 95 species of ants. We found three distinct endosymbiont groups—Wolbachia (Alphaproteobacteria: Rickettsiales), Spiroplasma (Firmicutes: Entomoplasmatales), -

The aim of this work was to isolate, Leaf-cutting ants; identify and complete the phylogenetic study of Leucoagaricus gongylophorus species of Acromyr- Leucoagaricus; mex pubescens. Macroscopic and microscopic features were used to identify the fungal symbiont Phylogeny of the ants. The ITS1-5.8S-ITS2 region was used as molecular marker for the molecular identifica- tion and to evaluate the phylogeny within the Leucoagaricus genus. One fungal symbiont associated with A. pubescens was isolated and identified as L. gongylophorus. The phylogeny of Leucoagaricus obtained using the ITS molecular marker revealed three well established monophyletic groups. It was possible to recognize one clade of Leucoagaricus associated with phylogenetically derived leaf-cutting ants (Acromyrmex and Atta). A second clade of free living forms of Leucoagaricus (non-cultivated), and a third clade of Leucoagaricus associated with phylogenetically basal genera of ants were also recognized. -
The Functions and Evolution of Social Fluid Exchange in Ant Colonies (Hymenoptera: Formicidae) Marie-Pierre Meurville & Adria C
ISSN 1997-3500 Myrmecological News myrmecologicalnews.org Myrmecol. News 31: 1-30 doi: 10.25849/myrmecol.news_031:001 13 January 2021 Review Article Trophallaxis: the functions and evolution of social fluid exchange in ant colonies (Hymenoptera: Formicidae) Marie-Pierre Meurville & Adria C. LeBoeuf Abstract Trophallaxis is a complex social fluid exchange emblematic of social insects and of ants in particular. Trophallaxis behaviors are present in approximately half of all ant genera, distributed over 11 subfamilies. Across biological life, intra- and inter-species exchanged fluids tend to occur in only the most fitness-relevant behavioral contexts, typically transmitting endogenously produced molecules adapted to exert influence on the receiver’s physiology or behavior. Despite this, many aspects of trophallaxis remain poorly understood, such as the prevalence of the different forms of trophallaxis, the components transmitted, their roles in colony physiology and how these behaviors have evolved. With this review, we define the forms of trophallaxis observed in ants and bring together current knowledge on the mechanics of trophallaxis, the contents of the fluids transmitted, the contexts in which trophallaxis occurs and the roles these behaviors play in colony life. We identify six contexts where trophallaxis occurs: nourishment, short- and long-term decision making, immune defense, social maintenance, aggression, and inoculation and maintenance of the gut microbiota. Though many ideas have been put forth on the evolution of trophallaxis, our analyses support the idea that stomodeal trophallaxis has become a fixed aspect of colony life primarily in species that drink liquid food and, further, that the adoption of this behavior was key for some lineages in establishing ecological dominance. -

Electronically produced using Free Software and in accomplishment with an Open Access spirit for academic publications Social behaviour in ants of the genus Leptothorax is reviewed. Attention is paid to the existence of collective robust periodic oscillations in the activity of ants inside the nest. It is known that those oscillations are the outcome of the process of short-distance interactions among ants and that the activity of individual workers is not periodic. Isolated workers can activate spontaneously in a unpredictable fashion. A model of an artificial society of computer automata endowed with the basic behavioural traits of Leptothorax ants is presented and it is demonstrated that collective periodic oscillations in the activity domain can exist as a consequence of interactions among the automata. -
Termites (Isoptera) in the Azores: an Overview of the Four Invasive Species Currently Present in the Archipelago
Arquipelago - Life and Marine Sciences ISSN: 0873-4704 Termites (Isoptera) in the Azores: an overview of the four invasive species currently present in the archipelago MARIA TERESA FERREIRA ET AL. Ferreira, M.T., P.A.V. Borges, L. Nunes, T.G. Myles, O. Guerreiro & R.H. Schef- frahn 2013. Termites (Isoptera) in the Azores: an overview of the four invasive species currently present in the archipelago. Arquipelago. Life and Marine Sciences 30: 39-55. In this contribution we summarize the current status of the known termites of the Azores (North Atlantic; 37-40° N, 25-31° W). Since 2000, four species of termites have been iden- tified in the Azorean archipelago. These are spreading throughout the islands and becoming common structural and agricultural pests. Two termites of the Kalotermitidae family, Cryp- totermes brevis (Walker) and Kalotermes flavicollis (Fabricius) are found on six and three of the islands, respectively. The other two species, the subterranean termites Reticulitermes grassei Clemént and R. flavipes (Kollar) of the Rhinotermitidae family are found only in confined areas of the cities of Horta (Faial) and Praia da Vitória (Terceira) respectively. Due to its location and weather conditions the Azorean archipelago is vulnerable to coloni- zation by invasive species. The fact that there are four different species of termites in the Azores, all of them considered pests, is a matter of concern. Here we present a comparative description of these species, their known distribution in the archipelago, which control measures are being used against them, and what can be done in the future to eradicate and control these pests in the Azores. -
Hymenoptera: Apidae), with Distributional Modeling of Adventive Euglossines
Comparative Genital Morphology, Phylogeny, and Classification of the Orchid Bee Genus Euglossa Latreille (Hymenoptera: Apidae), with Distributional Modeling of Adventive Euglossines BY ©2010 Ismael Alejandro Hinojosa Díaz Submitted to the graduate degree program in Ecology and Evolutionary Biology and the Graduate Faculty of the University of Kansas in partial fulfillment of the requirements for the degree of Doctor of Philosophy. Chairperson Michael S. Engel Charles D. Michener Edward O. Wiley Kirsten Jensen J. Christopher Brown Date Defended: November 10, 2010 The Dissertation Committee for Ismael Alejandro Hinojosa Díaz certifies that this is the approved version of the following dissertation: Comparative Genital Morphology, Phylogeny, and Classification of the Orchid Bee Genus Euglossa Latreille (Hymenoptera: Apidae), with Distributional Modeling of Adventive Euglossines Chairperson Michael S. Engel Date approved: November 22, 2010 ii ABSTRACT Orchid bees (tribe Euglossini) are conspicuous members of the corbiculate bees owing to their metallic coloration, long labiomaxillary complex, and the fragrance-collecting behavior of the males, more prominently (but not restricted) from orchid flowers (hence the name of the group). They are the only corbiculate tribe that is exclusively Neotropical and without eusocial members. Of the five genera in the tribe, Euglossa Latreille is the most diverse with around 120 species. Taxonomic work on this genus has been linked historically to the noteworthy secondary sexual characters of the males, which combined with the other notable external features, served as a basis for the subgeneric classification commonly employed. The six subgenera Dasystilbe Dressler, Euglossa sensu stricto, Euglossella Moure, Glossura Cockerell, Glossurella Dressler and Glossuropoda Moure, although functional for the most part, showed some intergradations (especially the last three), and no phylogenetic evaluation of their validity has been produced.
