“…is one of the most speciesrich genus with 1,524 species currently described with pandemic distribution (Janicki et al, 2016;Antweb, 2020;Antmaps, 2020), with diverse and well distributed workers by forest strata and dominant species that can change the regional diversity and ecosystem dynamic Silva-Viana et al, 2021;Vicente et al, 2016). Among the Camponotus species, Camponotus renggeri Emery, 1894 has the known distribution from Panamá to Uruguay (Brandão, 1991;Basset et al, 2012). Thus, the aim of this study was to know and characterize the ecological and environmental aspects of parasitism involving the entomopathogenic fungus Ophiocordyceps camponoti-renggeri Araujo et al, 2015 and the host ant Camponotus renggeri Emery, 1894, as well as expanding the area of occurrence of this interaction.…”

Entomopathogenic fungi are widely known to parasitize and manipulate the behavior of various orders of arthropods. In this study, we recorded parasitism involving the entomopathogenic fungus Ophiocordyceps camponoti-renggeri and host ants of the species Camponotus renggeri in a relic of Atlantic Forest in Caatinga biome, in addition to characterizing the environmental and ecological aspects of the interaction. We found 210 infected ant workers, fixed predominantly on the margins of the abaxial face of leaves of the local vegetation. Most ants used simple phyllotaxis leaves for fixation and death, whose size varied widely. The parasitized ants died about 1.5 m above the ground. These results suggest that Ophiocordyceps camponoti-renggeri has high virulence and that the behavioral changes induced in its hosts favor their fitness.

The evolution of social parasitism in Acromyrmex leaf-cutting ants: a test of Emery?s rule

et al. 2004

Summary. Emery's rule predicts that social parasites and their hosts share common ancestry and are therefore likely to be close relatives. Within the leaf-cutting ant genus Acromyrmex, two taxa of social parasites have been found, which are thought to occupy opposite grades of permanent social parasitism, based on their contrasting morphologies: Acromyrmex insinuator differs little in morphology from its freeliving congeneric host species and produces a worker caste, and is thus thought to represent an early grade of social parasitism. At the other extreme, Pseudoatta spp. exhibit a very specialised morphology and lack a worker caste, both of which are characteristics of an evolutionarily derived grade of social parasitism. Here we present a molecular phylogeny using partial sequences of cytochrome oxidase I and II of about half of the known Acromyrmex species including two social parasites, their hosts and all congeneric species occurring sympatrically. We show that the two inquiline parasites represent two separate origins of social parasitism in the genus Acromyrmex. The early-grade social parasite A. insinuator is highly likely to be the sister species of its host Acromyrmex echinator, but the derived social parasite Pseudoatta sp. is not the sister species of its extant host Acromyrmex rugosus.
