ABSTRACT Wolbachia is a widespread genus of maternally transmitted endosymbiotic bacteria that often manipulates the reproductive strategy and life history of its hosts to favor its own transmission. Wolbachia-mediated phenotypic effects are well characterized in solitary hosts, but effects in social hosts are unclear. The invasive pharaoh ant, Monomorium pharaonis, shows natural variation in Wolbachia infection between colonies and can be readily bred under laboratory conditions. We previously… Expand
Association between host wing morphology polymorphism and Wolbachia infection in Vollenhovia emeryi (Hymenoptera: Myrmicinae)
It is proposed that the long‐winged S morph is associated with potential resistance to Wolbachia infection and that WolbachIA infection does not influence clonal reproduction (as is the case in other ant species). Expand
Among the shapeshifters: parasite-induced morphologies in ants (Hymenoptera, Formicidae) and their relevance within the EcoEvoDevo framework
By assessing case studies of parasites causing morphological changes in their ant hosts, from the eighteenth century to current research, a first overview of relevant host and parasite taxa is presented and hypotheses about the underlying developmental and evolutionary mechanisms are discussed.

New Strains of Wolbachia Unveiling the Complexity of This Symbiotic Interaction in Solenopsis (Hymenoptera: Formicidae)
The phylogenetic relationship between the strains showed a polyphyletic pattern, indicative of the complexity of the evolutionary history of these bacteria in the analyzed species and the need for further studies that focus on understanding of this intricate relationship. Expand
From egg to adult: a developmental table of the ant Monomorium pharaonis
The first developmental table in ants, from egg to adult, for the Myrmicine ant Monomorium pharaonis is presented and will serve as a blueprint for the generation of future ant developmental tables, which is key to understanding how the remarkable diversity in ants evolved. Expand
The Evolution and Biogeography of Wolbachia in Ants (Hymenoptera: Formicidae)
The data suggest that supergroup F is the ancestral character state for Wolbachia infection in ants, and there is only one transition to super group A, and once ants acquired infection with supergroup A, there have been no other strains introduced. Expand
Evolution of contribution timing in public goods games
Two stage game theoretical models are developed to explore how the timing of contributions evolves and show how contributing rapidly is not necessarily optimal, because delayers can act as ‘cheats,’ avoiding contributing while reaping the benefits of the public good. Expand


Wolbachia-infected ant colonies have increased reproductive investment and an accelerated life cycle.
The effects of Wolbachia on the short- and longer-term reproductive and life history traits of pharaoh ant colonies are characterized and it is found that infected colonies had higher reproductive investment and produced more new queens, particularly when existing colony queens were three months old. Expand
Variable fitness effects of Wolbachia infection in Drosophila melanogaster
It is suggested that variable fitness effects, in both sexes, and which interact strongly with the genetic background of the host, could increase cytoplasmic drive rates in some genotypes and help explain the widespread persistence of Wolbachia bacteria in D. melanogaster populations. Expand
The distribution and evolutionary history of Wolbachia infection in native and introduced populations of the invasive argentine ant (Linepithema humile)
It is shown that infected and uninfected colonies are often adjacent to one another, supporting the proposition that little female‐mediated gene flow occurs among Argentine ant colonies. Expand
Loss of Wolbachia infection during colonisation in the invasive Argentine ant Linepithema humile
Data is reported showing that colonisation of new habitats is a possible mechanism leading to the loss of infection in Linepithema humile, and a molecular phylogeny based on sequences of the Wolbachia wsp gene indicates that L. humile has been infected by a single strain. Expand
From Parasite to Mutualist: Rapid Evolution of Wolbachia in Natural Populations of Drosophila
This work shows that the Wolbachia in California D. simulans have changed over the last 20 y so that infected females now exhibit an average 10% fecundity advantage over uninfected females in the laboratory, and suggests smaller but qualitatively similar changes in relative fecundities in nature. Expand
Dynamic Wolbachia prevalence in Acromyrmex leaf‐cutting ants: potential for a nutritional symbiosis
It is confirmed that workers are infected with one or two widespread wsp genotypes of Wolbachia, shown that colony prevalence is always 100% and two rare recombinant genotypes are characterized, suggesting an unknown mutualistic function in worker ant nutrition. Expand
Wolbachia in the Flesh: Symbiont Intensities in Germ-Line and Somatic Tissues Challenge the Conventional View of Wolbachia Transmission Routes
It is shown that Wolbachia are not focused on reproductive tissues of eusocial insects, and that non-reproductive tissues of queens and workers of the ant Acromyrmex echinatior, harbour substantial infections. Expand
Wolbachia infections in native and introduced populations of fire ants (Solenopsis spp.)
The presence of Wolbachia is reported in native South American populations of the fire ant Solenopsisinvicta, but the apparent absence of the bacteria in introduced populations of this pest species in the USA is reported. Expand
Rapid Sequential Spread of Two Wolbachia Variants in Drosophila simulans
The sequential spread over approximately 20 years in natural populations of D. simulans on the east coast of Australia of two Wolbachia variants, only one of which causes significant CI, with wRi displacing wAu since 2004 is described. Expand
Widespread occurrence of the microorganism Wolbachia in ants
A first PCR–based Wolbachia screening in ants is reported on, finding that out of 50 Indo–Australian species, 50% screened positive for an A–group strain, and one of these species also harboured a B-group strain in a double infection. Expand
