“…H. uvarum facilitates the exploitation of ripening fruit, since it grows equally well on ripe and unripe raspberries, which is another facet of its association with D. suzukii . Similarly, a match between plant substrate and fungal growth conditions regulates mutualistic interactions in fungus‐gardening ants (Bizarria et al., 2021; Fine Licht et al., 2010; Richard et al., 2005).…”

1. A goal in insect-microbe ecology is to understand the mechanisms regulating species associations and mutualistic interactions.2. The spotted wing drosophila Drosophila suzukii develops in ripening fruit, unlike other drosophilids that typically feed on overripe fruit, and is associated with the yeast Hanseniaspora uvarum.3. We hypothesized that D. suzukii and H. uvarum engage in niche construction leading to a mutualistic relation, facilitating the exploitation of fruit and berries as larval substrate.4. We show that H. uvarum proliferates on both ripe and on unripe raspberries, mediates attraction of D. suzukii larvae and adult flies, enhances egg-laying in mated females and is a sufficient food substrate to support larval development.Moreover, H. uvarum suppresses the antagonistic grey mould, Botrytis cinerea in collaboration with D. suzukii larvae, and produces less ethanol than baker's yeast. H. uvarum thus creates favourable conditions for D. suzukii larval development, which is susceptible to ethanol and grey mould. 5. D. suzukii, on the other hand, vectors H. uvarum to suitable substrates such as raspberries, where larval feeding activity enhances growth of H. uvarum. Larval feeding also helps to suppress B. cinerea, which otherwise outcompetes H. uvarum on raspberry, in the absence of fly larvae. 6. In conclusion, H. uvarum enhances D. suzukii larval development on unripe berries, and D. suzukii promotes H. uvarum dispersal and growth on berries. Yeast

“…Also, Leucocoprinus sp. has already been reported in fungiculture association with this ant species (Bizarria et al 2022). For the Macrocybe titans, there are already records of occurring near nests of unidentified leafcutter ants in Costa Rica (Pegler et Brazilian Journal of Animal and Environmental Research, Curitiba, v.5, n.4, p. 3935-3960, out./dez., 2022 Mueller and Mata, 2001).…”

Attini ants (Hymenoptera, Formicidae, Myrmicinae) have great diversity in exploiting food resources. However, little is known about the mycophagy involving Agaricales fungi (Basidiomycota, Agaricomycetes). Moreover, these associations are of paramount importance in riparian zones, as the interaction among soil, fauna and flora is fundamental to the maintenance of these environments. Thus, the aim of this study was to describe cases of mycophagy between ants and fungi in order to understand how these associations occur in riparian zones. To this, collections were made between 2021-2022 in the valleys of the Rio Vacacaí, Rio dos Sinos and Rio Pardo in the state of Rio Grande do Sul, Brazil. The samples were analyzed for characters macro and microscopic and identified taxonomically. Mycophagy activities of six species of ants worker were cataloged, among them Acromyrmex niger, Acromyrmex versicolor, Tranopelta gilva, Tranopelta subterranea, Pheidole flavens and Mycetosoritis hartmanni, which included in their diet the mushrooms Agaricus rufoaurantiacus, Macrocybe titans, Agrocybe underwoodii, Dactylosporina steffenii, Lepiota micropholis and Neopaxillus echinospermus, respectively. The observed interactions demonstrate the dispersal of fungal spores through ant body structures, such as legs, antennae, thorax and abdomen; basidiomata as aliment source, such as pileus, lamellae and stipe; and generalized and specialized levels of predation on various fungi structures. Our results demonstrate unprecedented mycophagous relationships and show that Agaricales fungi can be considered a food source for Attini in riparian zones in Brazil south.

“…Even more fascinating is the fact that black yeasts of the genus Phialophora and associates (Ascomycota: Chaetothyriales) have been reported to be associated with the attine ant symbiosis ( Figure 1 ; Little and Currie, 2007 ; Bizarria et al, 2022 ). Black yeasts are parasites known to derive nutrients from and suppress the growth of attine-ant Pseudonocardia ( Little and Currie, 2007 ).…”

In recent years, the insect microbiome has become the focus of many actinomycete researchers in their search for novel bioactive compounds with members of the order Hymenoptera at the forefront of the revolution. Hymenoptera encompasses all bees, wasps, ants, and sawflies and is the third largest insect order by species richness. Additionally, Hymenoptera is the most diverse insect order in terms of ecological roles, behaviors, and social systems, thus making it an ideal starting point in the search for symbiotic actinomycetes. The aim of this review is to summarize current knowledge on hymenopteran associations with actinomycetes including information on interactions between actinomycetes and hymenopterans, isolation, and screening methodologies, as well as novel actinomycete species and natural products discovered between early 2013 and 2023. A total of 19 new species were discovered within this time period, with the genus Streptomyces being represented by 11 species while the remaining 8 belonged to rare actinomycetes genera. In addition, 35 novel compounds were reported from hymenopteran-associated actinomycetes within the same time period with the majority originating from Streptomyces strains. The reported novel compounds exhibit a range of biological activities including antibacterial, antifungal, anticancer, anti-enzymatic, and antiproliferative activity, as well as cytotoxicity.
