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. -

Received: 18 December 2013; in revised form: 19 February 2014 / Accepted: 19 February 2014 / Published: 20 March 2014 Abstract: Brazilian forest producers have developed integrated management programs to increase the effectiveness of the control of leaf-cutting ants of the genera Atta and Acromyrmex. These measures reduced the costs and quantity of insecticides used in the plantations. Such integrated management programs are based on monitoring the ant nests, as well as the need and timing of the control methods. Chemical control employing baits is the most commonly used method, however, biological, mechanical and cultural control methods, besides plant resistance, can reduce the quantity of chemicals applied in the plantations. -
Acromyrmex Ameliae Sp. N. (Hymenoptera: Formicidae): a New Social Parasite of Leaf-Cutting Ants in Brazil

Four attine taxa are known to be social parasites of other attines. Acromyrmex (Pseudoatta) argentina argentina and Acromyrmex (Pseudoatta) argentina platensis (parasites of Acromyrmex lundi), and Acromyrmex sp. (a parasite of Acromyrmex rugosus) produce no worker caste. In contrast, the recently discovered Acromyrmex insinuator (a parasite of Acromyrmex echinatior) does produce workers. Here, we describe a new species, Acromyrmex ameliae, a social parasite of Acromyrmex subterraneus subterraneus and Acromyrmex subterraneus brunneus in Minas Gerais, Brasil. Like A. insinuator, it produces workers and appears to be closely related to its hosts. Similar social parasites may be fairly common in the fungus-growing ants, but overlooked due to the close resemblance between parasite and host workers. Key words Acromyrmex, leaf-cutting ants, social evolution, social parasitism DOI 10.1111/j.1744-7917.2007.00151.x Introduction species can coexist as social parasites in attine colonies, consuming the fungus garden (Brandão, 1990; Adams The fungus-growing ants (Tribe Attini) are a New World et al., 2000). -

Its flora and fauna diversity has been reported, but knowledge gap has been identified concerning the bacterial communities associated with the flora and fauna. This study focused on ants (Hymenoptera: Formicidae), which are dominant in forest canopy and play essential roles in the ecosystem functionality. A metagenomic sequencing approach based on amplified V3–V4 regions of the 16S rRNA was employed to investigate the bacterial communities associated with five arboreal ant species collected from MMFR. The collected ants were identified as Dolichoderus thoracicus, Myrmicaria sp., Colobopsis leonardi, Polyrhachis mindanaensis, and Polyrhachis semiinermis. The sequence analyses revealed that Proteobacteria, Spirochaetes, Firmicutes, Bacteroides, and Actinobacteria were the most abundant phyla. Individual analysis of the bacterial genera associated with the five ant species showed that unclassified members of Rhizobiaceae, Orbaceae, and Burkholderiaceae were dominant in D. -
Effects of Ω-ACTX-Hv1a/GNA, a Novel Protein Biopesticide Targeting Voltage-Gated Calcium Ion Channels, on Target and Non-Target Arthropod Species
Effects of ω-ACTX-Hv1a/GNA, a novel protein biopesticide targeting voltage-gated calcium ion channels, on target and non-target arthropod species Erich Yukio Tempel Nakasu Thesis submitted for the degree of Doctor of Philosophy (PhD) Faculty of Science, Agriculture and Engineering – School of Biology July/2014 Abstract An increasing human population is met with the challenge of feeding over 10 billion people by 2050. Nowadays, over 20% of crop production is lost to insect pests. Chemical control agents, in general, present broad-spectrum activity, killing both pests and beneficial organisms that would contribute to production (i.e. pollinators and natural enemies). Previously, the insecticidal voltage-gated calcium channel blocker peptide -ACTX-Hv1a (Hv1a) was linked to the ‘carrier’ molecule snowdrop lectin (GNA). The resulting fusion protein, Hv1a/GNA, is highly toxic towards lepidopteran and coleopteran pests, presenting potential for use as a biopesticide. Here, the fusion protein was shown to also be toxic to the hemipteran pests Sitobion avenae and Myzus persicae, via artificial diet and when expressed in transgenic plants. However, its effects on non-target arthropods have not been previously evaluated. Therefore, toxicity of Hv1a/GNA was tested against two beneficial insects, the parasitoid wasp Eulophus pennicornis via its host, Lacanobia oleracea, and the honeybee Apis mellifera. The fusion protein did not present any significant tri- trophic negative effects on E. pennicornis, even when injected into host larvae. Honeybee survival was slightly affected when fed on high doses of fusion protein representing a ‘worst-case scenario’, but lead to no detectable effects when dosed with field-relevant levels. -

Reconstructing the Functions of Endosymbiotic Mollicutes in Fungus
RESEARCH ARTICLE Reconstructing the functions of endosymbiotic Mollicutes in fungus- growing ants Panagiotis Sapountzis*, Mariya Zhukova, Jonathan Z Shik, Morten Schiott, Jacobus J Boomsma* Centre for Social Evolution, Department of Biology, University of Copenhagen, Copenhagen, Denmark Abstract Mollicutes, a widespread class of bacteria associated with animals and plants, were recently identified as abundant abdominal endosymbionts in healthy workers of attine fungus- farming leaf-cutting ants. We obtained draft genomes of the two most common strains harbored by Panamanian fungus-growing ants. Reconstructions of their functional significance showed that they are independently acquired symbionts, most likely to decompose excess arginine consistent with the farmed fungal cultivars providing this nitrogen-rich amino-acid in variable quantities. Across the attine lineages, the relative abundances of the two Mollicutes strains are associated with the substrate types that foraging workers offer to fungus gardens. One of the symbionts is specific to the leaf-cutting ants and has special genomic machinery to catabolize citrate/glucose into acetate, which appears to deliver direct metabolic energy to the ant workers. Unlike other Mollicutes associated with insect hosts, both attine ant strains have complete phage-defense systems, underlining that they are actively maintained as mutualistic symbionts.
